Documentation: ABI: IIO: Re-add sysfs-bus-iio-adc-ad4130
The ad4130 driver exports in_voltageY-voltageZ_filter_mode and
in_voltage-voltage_filter_mode_available attributes to user space. A
previous patch merged the documentation for those attributes with the
documentation for filter_type/filter_type_available into sysfs-bus-iio.
Filter mode and filter type refer to the same feature which is the digital
filter applied over ADC samples. However, since datasheets use the term
`filter type` and ad4130 driver is the only one using filter_mode,
deprecate the filter_mode ABI in favor of filter_type and keep the docs
separate to avoid confusion and intricate attribute descriptions.
Fixes:

Documentation: ABI: IIO: Add filter_type documentation
A previous patch added documentation for filter_type_available attributes.
However, the description for the value attribute (filter_type) was missing.
Add documentation for filter_type sysfs ABI.

HID: hid-appletb-kbd: add driver for the keyboard mode of Apple Touch Bars
The Touch Bars found on x86 Macs support two USB configurations: one where the device presents itself as a HID keyboard and can display predefined sets of keys, and one where the operating system has full control over what is displayed. This commit adds a driver for the display functionality of the first configuration. Note that currently only T2 Macs are supported. This driver is based on previous work done by Ronald Tschalär <ronald@innovation.ch>.

platform/chrome: cros_ec_sysfs: Expose AP_MODE_ENTRY feature state
This adds sysfs attribute /sys/class/chromeos/cros_ec/ap_mode_entry to expose the status of the AP_MODE_ENTRY feature. This attribute indicate whether the EC requires direction from the Application Processor (AP) before entering Type-C alternate modes or USB4 mode.

First batch of fixes for 6.14. Nothing really stands out,
but as usual there's a slight concentration of fixes for issues
added in the last two weeks before the MW, and driver bugs
from 6.13 which tend to get discovered upon wider distribution.
Including fixes from IPSec, netfilter and Bluetooth.
Current release - regressions:
- net: revert RTNL changes in unregister_netdevice_many_notify()
- Bluetooth: fix possible infinite recursion of btusb_reset
- eth: adjust locking in some old drivers which protect their state
with spinlocks to avoid sleeping in atomic; core protects
netdev state with a mutex now
Previous releases - regressions:
- eth: mlx5e: make sure we pass node ID, not CPU ID to kvzalloc_node()
- eth: bgmac: reduce max frame size to support just 1500 bytes;
the jumbo frame support would previously cause OOB writes,
but now fails outright
- mptcp: blackhole only if 1st SYN retrans w/o MPC is accepted,
avoid false detection of MPTCP blackholing
Previous releases - always broken:
- mptcp: handle fastopen disconnect correctly
- xfrm: make sure skb->sk is a full sock before accessing its fields
- xfrm: fix taking a lock with preempt disabled for RT kernels
- usb: ipheth: improve safety of packet metadata parsing; prevent
potential OOB accesses
- eth: renesas: fix missing rtnl lock in suspend/resume path

properly. Should make many SteamOS users happy. Even comes with
tests!
- Large IIO driver updates and bugfixes
- FPGA driver updates
- Coresight driver updates
- MHI driver updates
- PPS driver updatesa
- const bin_attribute reworking for many drivers
- binder driver updates
- smaller driver updates and fixes

power supply and reset changes for the 6.14 series
* power-supply core
- introduce power supply extensions, which allows adding properties to
a power supply device from a separate driver. This will be used
initially to extend the generic ACPI charger/battery driver with
vendor extensions for charge thresholds.
- convert all drivers from power_supply_for_each_device to new
power_supply_for_each_psy(), which avoids lots of casting being
done in the drivers.
- avoid LED trigger like values in uevent for POWER_SUPPLY_PROP_CHARGE_BEHAVIOUR
- introduce POWER_SUPPLY_PROP_CHARGE_TYPES, which is similar to the
POWER_SUPPLY_PROP_CHARGE_TYPE property, but also lists the available
options on the specific platform
* power-supply drivers
- dell-laptop: use new power_supply_charge_types_show/_parse helpers
- stc3117: new driver for equally named fuel gauge chip
- bq24190: add support for new POWER_SUPPLY_PROP_CHARGE_TYPES
- bq24190: add BQ24297 support
- bq27xxx: add voltage min design for bq27000/bq27200
- cros_charge-control: convert to new power supply extension API
- multiple drivers: constify 'struct bin_attribute'
- ds2782: convert to device managed resources
- max1720x: add charge full property

The various patchsets are summarized below. Plus of course many
indivudual patches which are described in their changelogs. - "Allocate and free frozen pages" from Matthew Wilcox reorganizes the page allocator so we end up with the ability to allocate and free zero-refcount pages. So that callers (ie, slab) can avoid a refcount inc & dec. - "Support large folios for tmpfs" from Baolin Wang teaches tmpfs to use large folios other than PMD-sized ones. - "Fix mm/rodata_test" from Petr Tesarik performs some maintenance and fixes for this small built-in kernel selftest. - "mas_anode_descend() related cleanup" from Wei Yang tidies up part of the mapletree code. - "mm: fix format issues and param types" from Keren Sun implements a few minor code cleanups. - "simplify split calculation" from Wei Yang provides a few fixes and a test for the mapletree code. - "mm/vma: make more mmap logic userland testable" from Lorenzo Stoakes continues the work of moving vma-related code into the (relatively) new mm/vma.c. - "mm/page_alloc: gfp flags cleanups for alloc_contig_*()" from David Hildenbrand cleans up and rationalizes handling of gfp flags in the page allocator. - "readahead: Reintroduce fix for improper RA window sizing" from Jan Kara is a second attempt at fixing a readahead window sizing issue. It should reduce the amount of unnecessary reading. - "synchronously scan and reclaim empty user PTE pages" from Qi Zheng addresses an issue where "huge" amounts of pte pagetables are accumulated (https://lore.kernel.org/lkml/cover.1718267194.git.zhengqi.arch@bytedance.com/). Qi's series addresses this windup by synchronously freeing PTE memory within the context of madvise(MADV_DONTNEED). - "selftest/mm: Remove warnings found by adding compiler flags" from Muhammad Usama Anjum fixes some build warnings in the selftests code when optional compiler warnings are enabled. - "mm: don't use __GFP_HARDWALL when migrating remote pages" from David Hildenbrand tightens the allocator's observance of __GFP_HARDWALL. - "pkeys kselftests improvements" from Kevin Brodsky implements various fixes and cleanups in the MM selftests code, mainly pertaining to the pkeys tests. - "mm/damon: add sample modules" from SeongJae Park enhances DAMON to estimate application working set size. - "memcg/hugetlb: Rework memcg hugetlb charging" from Joshua Hahn provides some cleanups to memcg's hugetlb charging logic. - "mm/swap_cgroup: remove global swap cgroup lock" from Kairui Song removes the global swap cgroup lock. A speedup of 10% for a tmpfs-based kernel build was demonstrated. - "zram: split page type read/write handling" from Sergey Senozhatsky has several fixes and cleaups for zram in the area of zram_write_page(). A watchdog softlockup warning was eliminated. - "move pagetable_*_dtor() to __tlb_remove_table()" from Kevin Brodsky cleans up the pagetable destructor implementations. A rare use-after-free race is fixed. - "mm/debug: introduce and use VM_WARN_ON_VMG()" from Lorenzo Stoakes simplifies and cleans up the debugging code in the VMA merging logic. - "Account page tables at all levels" from Kevin Brodsky cleans up and regularizes the pagetable ctor/dtor handling. This results in improvements in accounting accuracy. - "mm/damon: replace most damon_callback usages in sysfs with new core functions" from SeongJae Park cleans up and generalizes DAMON's sysfs file interface logic. - "mm/damon: enable page level properties based monitoring" from SeongJae Park increases the amount of information which is presented in response to DAMOS actions. - "mm/damon: remove DAMON debugfs interface" from SeongJae Park removes DAMON's long-deprecated debugfs interfaces. Thus the migration to sysfs is completed. - "mm/hugetlb: Refactor hugetlb allocation resv accounting" from Peter Xu cleans up and generalizes the hugetlb reservation accounting. - "mm: alloc_pages_bulk: small API refactor" from Luiz Capitulino removes a never-used feature of the alloc_pages_bulk() interface. - "mm/damon: extend DAMOS filters for inclusion" from SeongJae Park extends DAMOS filters to support not only exclusion (rejecting), but also inclusion (allowing) behavior. - "Add zpdesc memory descriptor for zswap.zpool" from Alex Shi "introduces a new memory descriptor for zswap.zpool that currently overlaps with struct page for now. This is part of the effort to reduce the size of struct page and to enable dynamic allocation of memory descriptors." - "mm, swap: rework of swap allocator locks" from Kairui Song redoes and simplifies the swap allocator locking.

perf-tools changes for v6.14
There are a lot of changes in the perf tools in this cycle.
build
-----
* Use generic syscall table to generate syscall numbers on supported archs.
* This also enables to get rid of libaudit which was used for syscall numbers.
* Remove python2 support as it's deprecated for years.
* Fix issues on static build with libzstd.
perf record
-----------
* Intel-PT supports "aux-action" config term to pause or resume tracing in
the aux-buffer. Users can start the intel_pt event as "started-paused" and
configure other events to control the Intel-PT tracing.
# perf record --kcore -e intel_pt/aux-action=start-paused/ \
-e syscalls:sys_enter_newuname/aux-action=resume/ \
-e syscalls:sys_exit_newuname/aux-action=pause/ -- uname
This requires the kernel support (which was added in v6.13).
perf lock
---------
* 'perf lock contention' command has an ability to symbolize locks in
dynamically allocated objects using slab cache name when it runs with BPF.
Those dynamic locks would have "&" prefix in the name to distinguish them
from ordinary (static) locks.
# perf lock con -abl -E 5 sleep 1
contended total wait max wait avg wait address symbol
2 1.95 us 1.77 us 975 ns ffff9d5e852d3498 &task_struct (mutex)
1 1.18 us 1.18 us 1.18 us ffff9d5e852d3538 &task_struct (mutex)
4 1.12 us 354 ns 279 ns ffff9d5e841ca800 &kmalloc-cg-512 (mutex)
2 859 ns 617 ns 429 ns ffffffffa41c3620 delayed_uprobe_lock (mutex)
3 691 ns 388 ns 230 ns ffffffffa41c0940 pack_mutex (mutex)
This also requires the kernel/BPF support (which was added in v6.13).
perf ftrace
-----------
* 'perf ftrace latency' command gets a couple of options to support linear
buckets instead of exponential. Also it's possible to specify max and
min latency for the linear buckets.
# perf ftrace latency -abn -T switch_mm_irqs_off --bucket-range=100 \
--min-latency=200 --max-latency=800 -- sleep 1
# DURATION | COUNT | GRAPH |
0 - 200 ns | 186 | ### |
200 - 300 ns | 256 | ##### |
300 - 400 ns | 364 | ####### |
400 - 500 ns | 223 | #### |
500 - 600 ns | 111 | ## |
600 - 700 ns | 41 | |
700 - 800 ns | 141 | ## |
800 - ... ns | 169 | ### |
# statistics (in nsec)
total time: 2162212
avg time: 967
max time: 16817
min time: 132
count: 2236
* As you can see in the above example, it nows shows the statistics at the
end so that users can see the avg/max/min latencies easily.
* 'perf ftrace profile' command has --graph-opts option like 'perf ftrace
trace' so that it can control the tracing behaviors in the same way.
For example, it can limit the function call depth or threshold.
perf script
-----------
* Improve physical memory resolution in 'mem-phys-addr' script by parsing
/proc/iomem file.
# perf script mem-phys-addr -- find /
...
Event: mem_inst_retired.all_loads:P
Memory type count percentage

* 'perf test' gets --runs-per-test option to run the test cases repeatedly.
This would be helpful to see if it's flaky.
* Add 'parse_events' method to Python perf extension module, so that users
can use the same event parsing logic in the python code. One more step
towards implementing perf tools in Python. :)
* Support opening tracepoint events without libtraceevent. This will be
helpful if it won't use the tracing data like in 'perf stat'.
* Update ARM Neoverse N2/V2 JSON events and metrics

Merge tag 'perf-tools-for-v6.14-2025-01-21' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools
Pull perf-tools updates from Namhyung Kim:
"There are a lot of changes in the perf tools in this cycle.
build:
- Use generic syscall table to generate syscall numbers on supported
archs
- This also enables to get rid of libaudit which was used for syscall
numbers
- Remove python2 support as it's deprecated for years
- Fix issues on static build with libzstd
perf record:
- Intel-PT supports "aux-action" config term to pause or resume
tracing in the aux-buffer. Users can start the intel_pt event as
"started-paused" and configure other events to control the Intel-PT
tracing:
# perf record --kcore -e intel_pt/aux-action=start-paused/ \
-e syscalls:sys_enter_newuname/aux-action=resume/ \
-e syscalls:sys_exit_newuname/aux-action=pause/ -- uname
This requires kernel support (which was added in v6.13)
perf lock:
- 'perf lock contention' command has an ability to symbolize locks in
dynamically allocated objects using slab cache name when it runs
with BPF. Those dynamic locks would have "&" prefix in the name to
distinguish them from ordinary (static) locks
# perf lock con -abl -E 5 sleep 1
contended total wait max wait avg wait address symbol
2 1.95 us 1.77 us 975 ns ffff9d5e852d3498 &task_struct (mutex)
1 1.18 us 1.18 us 1.18 us ffff9d5e852d3538 &task_struct (mutex)
4 1.12 us 354 ns 279 ns ffff9d5e841ca800 &kmalloc-cg-512 (mutex)
2 859 ns 617 ns 429 ns ffffffffa41c3620 delayed_uprobe_lock (mutex)
3 691 ns 388 ns 230 ns ffffffffa41c0940 pack_mutex (mutex)
This also requires kernel/BPF support (which was added in v6.13)
perf ftrace:
- 'perf ftrace latency' command gets a couple of options to support
linear buckets instead of exponential. Also it's possible to
specify max and min latency for the linear buckets:
# perf ftrace latency -abn -T switch_mm_irqs_off --bucket-range=100 \
--min-latency=200 --max-latency=800 -- sleep 1
# DURATION | COUNT | GRAPH |
0 - 200 ns | 186 | ### |
200 - 300 ns | 256 | ##### |
300 - 400 ns | 364 | ####### |
400 - 500 ns | 223 | #### |
500 - 600 ns | 111 | ## |
600 - 700 ns | 41 | |
700 - 800 ns | 141 | ## |
800 - ... ns | 169 | ### |
# statistics (in nsec)
total time: 2162212
avg time: 967
max time: 16817
min time: 132
count: 2236
- As you can see in the above example, it nows shows the statistics
at the end so that users can see the avg/max/min latencies easily
- 'perf ftrace profile' command has --graph-opts option like 'perf
ftrace trace' so that it can control the tracing behaviors in the
same way. For example, it can limit the function call depth or
threshold
perf script:
- Improve physical memory resolution in 'mem-phys-addr' script by
parsing /proc/iomem file
# perf script mem-phys-addr -- find /
...
Event: mem_inst_retired.all_loads:P
Memory type count percentage

IIO: 1st set of new device support, features and cleanup for 6.14
Fairly quiet cycle. Usual mix of new drivers, device support in
existing drivers, features and more general rework and cleanup.
There are a few late breaking or long standing but complex fixes
in here as well.
There is one expected merge conflict due to an upstream fix touching
neighboring code in ti-ads1119. The trivial resolution is the right one with
the result ending up as:
struct {
s16 sample;
aligned_s64 timestamp;
} scan;
New device support
==================
adi,ad4000
- Add support for many Pulsar ADC devices: AD7685, AD7686, AD7687, AD7688,
AD7690, AD7691, AD7693, AD7942, AD7946, AD7980, AD7982, AD7983, AD7984,
AD7988-1 and AD7988-5 ADCs. Generally similar to the AD4000 series
but with lower sampling rates and no configuration registers.
Includes addition of timestamp channels.
adi,adis16480
- Add support for ADIS16486, ADIS16487 and ADIS16489 IMUs. Required a few tweaks
to existing driver and addition of tables.
kionix,kx022a
- Add support for KX134ACR-LBZ accelerometer that is similar to the
KX132ACR-LBZ but with a wider (+-64G) sensor range.
- Add support for KX134-1211 accelerometer that is similar to the
KX132-1211 but with a wider (+-16G) sensor range.
nxp,fxls8962af
- Add support for fxls8974cf and fxls8967af accelerometers, Both are
compatible with fxls8962af but with different device IDs which are used in
presence checks.
renesas,rzg2l
- Add support for Renesas RZ/GS3 SoC ADCs (various driver refactors
precede this to allow for chip differences).
rohm,bd79704
- New driver for this 6 channel DAC.
st,mpu6050
- Support he IAM20380 which is effectively a cut down IAM20608 IMU with only
a gyroscope (no accelerometer).
st,stm-timmer-trigger
- Add support for ADC trigger use case for the STM32MP25 SOC. Do not support
the counter functionality in this driver as that is handled by the
counter subsystem.
ti,opt4060
- New driver for this RGBW color sensor.
Driver drop
===========
rohm,bu20008
- Drop as decision was made to not mass produce this light sensor after
Matti had done all the work to get a driver upstream.
Features
========
adi,ad_sigma_delta library + ad7124
- Allow for GPIO to check interrupt status, enabling this device on
more platforms that don't obey prior (non general) assumptions on
how the interrupt chips work.
- Allow variation in reset sequence length allowing chip specific
optimizations rather than always using worst case.
adi,ad7124
- Add temperature channel support.
adi,ad7173
- Add support calibration modes for this family of ADCs.
adi,adxl345
- Binding update to allow specification of which interrupt line is
connected (or none).
- Support interrupts and FIFO based data capture.
bosch,bme680
- Add regulators support. Note this required a new binding doc rather than
use of trivial-devices
- Runtime PM support.
microchip,pac1921
- Add ACPI support including _DSM for shunt value and label.
renesas,rzg2l
- Enable runtime autosuspend.
- Add suspend and resume support.
tyhx,hx9023s
- Add loading of a firmware file used to set defaults for some
configuration registers.
vishay,veml6030
- Support triggered buffers allowing efficient data capture at
higher speeds.
- Add regmap cache to reduce access to device.
Cleanup and minor fixes
=======================
cross-tree
- Another batch of conversions to devm_regulator_get_enable_read_voltage()
helper and related conversions to full devm that this enables.
- Various patches using guard() to allow early returns and simpler
code flow.
- Various conversions from s64 timestamp __aligned(8) to aligned_s64 type.
Includes a few cleanups where this unsigned and it should have been
signed.
- Fix up some missing types for drive-open-drain in dt-binding docs.
core
- Add missing documentation for iio_dmaengine_buffer_setup_ext()
- Add check that all buffers passed to iio_read_channel_ext_info()
and iio_read_channel_label() are page sized and page aligned.
Done this way because the callbacks are almost always only used
to fill sysfs attributes. The check covers the tiny percentage
of cases where use is made of this data in a consumer driver.
- Mark scan_timestamp memory of struct iio_dev private ensuring no
drivers change the value which belongs to the IIO core.
documentation
- Various missing ABI docs added.
- ABI docs made to use Y consistently as the wildcard for channel
number.
- Combine duplicate in_currentY_raw entries in ABI docs.
iio-mux
- Fix alignment of buffers passed to iio_channel_read_ext_info().
adi,ad_sigma_delta library
- Respect keep_cs_asserted flag in read path.
- Close a race condition around irq enabling and disabling.
- Use explicit unsigned int in place of unsigned.
adi,ad6695
- Move dt-binding header under adc sub-directory and fix include path in dt
example.
adi,ad7124
- Check number of channels in DT doesn't exceed what the driver can handle.
- Check input specified in DT are possible.
- Improved error reporting during probe.
adi,ad7173
- Drop unused structure element.
adi,ad7293
- Ensure power is turned on before resetting.
adi,adxl345
- Some documentation simplification and parameter renames.
- Add a function than unifies handling of power up and power down.
- Add defines to have a complete set of registers defined.
- Add missing \n to end of error messages.
amlogic,meson_saradc
- Simplify handling of the REG11 register access.
awinic,aw96104
- Constify iio_info structure.
bosch,bmp085
- Add to dt-binding to indicate devices support SPI.
bosch,bmp280
- Use sizeof() to replace a somewhat magic 2.
- Rename sleep related variables so the unit is included and use
fsleep() to replace usleep_range() calls.
bosch,bno055
- Constify struct bin_attribute
capella,cm3232
- Reset device before checking hardware ID inline with suggested flow
from datasheet.
diolan,dln2
- Simplify zeroing of structure used to gather up data by just
clearing the whole thing before writing rather than trying to
clear out he padding after write.
freescale,vf610
- Use devm_ and dev_error_probe() to simplify code and allow dropping
of explicit remove() callback.
invensense,timestamp library
- Use a cast to remove possibility of integer overflow.
kionix,kx022a
- Increase reset delay a little.
maxim,max1363
- Use a buffer of sufficient size in iio_priv() rather than allocating
variable sized buffer at use time.
microchip,mcp4725
- Replace of_property_read_bool() with of_property_present() for
detecting presence of regulator which is obviously not a bool.
nxp,fxls8962af
- Add wakeup-source property to the dt binding to allow these sensors
to wake the system up from suspend.
- Enable finer grained build when not all bus types need to be supported.
renesas,rzg2l
- Use dev_err_probe(), improving handling of probe errors and simplifying
code.
- Convert to devm_ based cleanup.
- Remove unnecessary runtime PM complexity as clocks are managed through
PM domains.
- Switch pm_ptr() removing need for __maybe_unused markings.
- use read_poll_timeout() to replace open coded equivalent.
samsung, ssp_sensors
- Simplify code by always providing timestamp whether or not it
is enabled.
st,lsm6dsx
- Avoid need to include linux/i3c/master by using i3cdev_to_dev() to
get to the contained struct device.
st,stm32-timer-trigger
- Check for clk_enable() fails.
vishay,veml6030
- Use new gts-helper functions and fix the _scale attribute to take into
account changes in gain and integration time.
Various other typo fixes in variable names + documentation and help text.
A few whitespace cleanup patches.

to fill sysfs attributes. The check covers the tiny percentage
of cases where use is made of this data in a consumer driver.

We aren't aware of any users who are likely to be using recent kernels.

power: supply: core: Add new "charge_types" property
Add a new "charge_types" property, this is identical to "charge_type" but reading returns a list of supported charge-types with the currently active type surrounded by square brackets, e.g.: Fast [Standard] "Long_Life" This has the advantage over the existing "charge_type" property that this allows userspace to find out which charge-types are supported for writable charge_type properties. Drivers which already support "charge_type" can easily add support for this by setting power_supply_desc.charge_types to a bitmask representing valid charge_type values. The existing "charge_type" get_property() and set_property() code paths can be re-used for "charge_types".

Char/Misc/IIO/Whatever driver subsystem updates for 6.13-rc1
Here is the "big and hairy" char/misc/iio and other small driver
subsystem updates for 6.13-rc1. Sorry for doing this at the end of the
merge window, conference and holiday travel got in the way on my side
(hence the 5am pull request emails...)
Loads of things in here, and even a fun merge conflict!
- rust misc driver bindings and other rust changes to make misc
drivers actually possible. I think this is the tipping point,
expect to see way more rust drivers going forward now that these
bindings are present. Next merge window hopefully we will have pci
and platform drivers working, which will fully enable almost all
driver subsystems to start accepting (or at least getting) rust
drivers. This is the end result of a lot of work from a lot of
people, congrats to all of them for getting this far, you've proved
many of us wrong in the best way possible, working code :)
- IIO driver updates, too many to list individually, that subsystem
keeps growing and growing...
- Interconnect driver updates
- nvmem driver updates
- pwm driver updates
- platform_driver::remove() fixups, loads of them
- counter driver updates
- misc driver updates (keba?)
- binder driver updates and fixes
- loads of other small char/misc/etc driver updates and additions,
full details in the shortlog.
Note, there is a semi-hairy rust merge conflict when pulling this. The
resolution has been in linux-next for a while and can be seen here:
https://lore.kernel.org/all/20241111173459.2646d4af@canb.auug.org.au/
All of these have been in linux-next for a while, with no other reported
issues other than that merge conflict.

USB / Thunderbolt (USB4) changes for 6.13-rc1
Here is the big set of USB and Thunderbolt changes for 6.13-rc1.

Pull PCI updates from Bjorn Helgaas:
"Enumeration:
- Make pci_stop_dev() and pci_destroy_dev() safe so concurrent
callers can't stop a device multiple times, even as we migrate from
the global pci_rescan_remove_lock to finer-grained locking (Keith
Busch)
- Improve pci_walk_bus() implementation by making it recursive and
moving locking up to avoid need for a 'locked' parameter (Keith
Busch)
- Unexport pci_walk_bus_locked(), which is only used internally by
the PCI core (Keith Busch)
- Detect some Thunderbolt chips that are built-in and hence
'trustworthy' by a heuristic since the 'ExternalFacingPort' and
'usb4-host-interface' ACPI properties are not quite enough (Esther
Shimanovich)
Resource management:
- Use PCI bus addresses (not CPU addresses) in 'ranges' properties
when building dynamic DT nodes so systems where PCI and CPU
addresses differ work correctly (Andrea della Porta)
- Tidy resource sizing and assignment with helpers to reduce
redundancy (Ilpo Järvinen)
- Improve pdev_sort_resources() 'bogus alignment' warning to be more
specific (Ilpo Järvinen)
Driver binding:
- Convert driver .remove_new() callbacks to .remove() again to finish
the conversion from returning 'int' to being 'void' (Sergio
Paracuellos)
- Export pcim_request_all_regions(), a managed interface to request
all BARs (Philipp Stanner)
- Replace pcim_iomap_regions_request_all() with
pcim_request_all_regions(), and pcim_iomap_table()[n] with
pcim_iomap(n), in the following drivers: ahci, crypto qat, crypto
octeontx2, intel_th, iwlwifi, ntb idt, serial rp2, ALSA korg1212
(Philipp Stanner)
- Remove the now unused pcim_iomap_regions_request_all() (Philipp
Stanner)
- Export pcim_iounmap_region(), a managed interface to unmap and
release a PCI BAR (Philipp Stanner)
- Replace pcim_iomap_regions(mask) with pcim_iomap_region(n), and
pcim_iounmap_regions(mask) with pcim_iounmap_region(n), in the
following drivers: fpga dfl-pci, block mtip32xx, gpio-merrifield,
cavium (Philipp Stanner)
Error handling:
- Add sysfs 'reset_subordinate' to reset the entire hierarchy below a
bridge; previously Secondary Bus Reset could only be used when
there was a single device below a bridge (Keith Busch)
- Warn if we reset a running device where the driver didn't register
pci_error_handlers notification callbacks (Keith Busch)
ASPM:
- Disable ASPM L1 before touching L1 PM Substates to follow the spec
closer and avoid a CPU load timeout on some platforms (Ajay
Agarwal)
- Set devices below Intel VMD to D0 before enabling ASPM L1 Substates
as required per spec for all L1 Substates changes (Jian-Hong Pan)
Power management:
- Enable starfive controller runtime PM before probing host bridge
(Mayank Rana)
- Enable runtime power management for host bridges (Krishna chaitanya
chundru)
Power control:
- Use of_platform_device_create() instead of of_platform_populate()
to create pwrctl platform devices so we can control it based on the
child nodes (Manivannan Sadhasivam)
- Create pwrctrl platform devices only if there's a relevant power
supply property (Manivannan Sadhasivam)
- Add device link from the pwrctl supplier to the PCI dev to ensure
pwrctl drivers are probed before the PCI dev driver; this avoids a
race where pwrctl could change device power state while the PCI
driver was active (Manivannan Sadhasivam)
- Find pwrctl device for removal with of_find_device_by_node()
instead of searching all children of the parent (Manivannan
Sadhasivam)
- Rename 'pwrctl' to 'pwrctrl' to match new bandwidth controller
('bwctrl') and hotplug files (Bjorn Helgaas)
Bandwidth control:
- Add read/modify/write locking for Link Control 2, which is used to
manage Link speed (Ilpo Järvinen)
- Extract Link Bandwidth Management Status check into
pcie_lbms_seen(), where it can be shared between the bandwidth
controller and quirks that use it to help retrain failed links
(Ilpo Järvinen)
- Re-add Link Bandwidth notification support with updates to address
the reasons it was previously reverted (Alexandru Gagniuc, Ilpo
Järvinen)
- Add pcie_set_target_speed() and related functionality so drivers
can manage PCIe Link speed based on thermal or other constraints
(Ilpo Järvinen)
- Add a thermal cooling driver to throttle PCIe Links via the
existing thermal management framework (Ilpo Järvinen)
- Add a userspace selftest for the PCIe bandwidth controller (Ilpo
Järvinen)
PCI device hotplug:
- Add hotplug controller driver for Marvell OCTEON multi-function
device where function 0 has a management console interface to
enable/disable and provision various personalities for the other
functions (Shijith Thotton)
- Retain a reference to the pci_bus for the lifetime of a pci_slot to
avoid a use-after-free when the thunderbolt driver resets USB4 host
routers on boot, causing hotplug remove/add of downstream docks or
other devices (Lukas Wunner)
- Remove unused cpcihp struct cpci_hp_controller_ops.hardware_test
(Guilherme Giacomo Simoes)
- Remove unused cpqphp struct ctrl_dbg.ctrl (Christophe JAILLET)
- Use pci_bus_read_dev_vendor_id() instead of hand-coded presence
detection in cpqphp (Ilpo Järvinen)
- Simplify cpqphp enumeration, which is already simple-minded and
doesn't handle devices below hot-added bridges (Ilpo Järvinen)
Virtualization:
- Add ACS quirk for Wangxun FF5xxx NICs, which don't advertise an ACS
capability but do isolate functions as though PCI_ACS_RR and
PCI_ACS_CR were set, so the functions can be in independent IOMMU
groups (Mengyuan Lou)
TLP Processing Hints (TPH):
- Add and document TLP Processing Hints (TPH) support so drivers can
enable and disable TPH and the kernel can save/restore TPH
configuration (Wei Huang)
- Add TPH Steering Tag support so drivers can retrieve Steering Tag
values associated with specific CPUs via an ACPI _DSM to improve
performance by directing DMA writes closer to their consumers (Wei
Huang)
Data Object Exchange (DOE):
- Wait up to 1 second for DOE Busy bit to clear before writing a
request to the mailbox to avoid failures if the mailbox is still
busy from a previous transfer (Gregory Price)
Endpoint framework:
- Skip attempts to allocate from endpoint controller memory window if
the requested size is larger than the window (Damien Le Moal)
- Add and document pci_epc_mem_map() and pci_epc_mem_unmap() to
handle controller-specific size and alignment constraints, and add
test cases to the endpoint test driver (Damien Le Moal)
- Implement dwc pci_epc_ops.align_addr() so pci_epc_mem_map() can
observe DWC-specific alignment requirements (Damien Le Moal)
- Synchronously cancel command handler work in endpoint test before
cleaning up DMA and BARs (Damien Le Moal)
- Respect endpoint page size in dw_pcie_ep_align_addr() (Niklas
Cassel)
- Use dw_pcie_ep_align_addr() in dw_pcie_ep_raise_msi_irq() and
dw_pcie_ep_raise_msix_irq() instead of open coding the equivalent
(Niklas Cassel)
- Avoid NULL dereference if Modem Host Interface Endpoint lacks
'mmio' DT property (Zhongqiu Han)
- Release PCI domain ID of Endpoint controller parent (not controller
itself) and before unregistering the controller, to avoid
use-after-free (Zijun Hu)
- Clear secondary (not primary) EPC in pci_epc_remove_epf() when
removing the secondary controller associated with an NTB (Zijun Hu)
Cadence PCIe controller driver:
- Lower severity of 'phy-names' message (Bartosz Wawrzyniak)
Freescale i.MX6 PCIe controller driver:
- Fix suspend/resume support on i.MX6QDL, which has a hardware
erratum that prevents use of L2 (Stefan Eichenberger)
Intel VMD host bridge driver:
- Add 0xb60b and 0xb06f Device IDs for client SKUs (Nirmal Patel)
MediaTek PCIe Gen3 controller driver:
- Update mediatek-gen3 DT binding to require the exact number of
clocks for each SoC (Fei Shao)
- Add support for DT 'max-link-speed' and 'num-lanes' properties to
restrict the link speed and width (AngeloGioacchino Del Regno)
Microchip PolarFlare PCIe controller driver:
- Add DT and driver support for using either of the two PolarFire
Root Ports (Conor Dooley)
NVIDIA Tegra194 PCIe controller driver:
- Move endpoint controller cleanups that depend on refclk from the
host to the notifier that tells us the host has deasserted PERST#,
when refclk should be valid (Manivannan Sadhasivam)
Qualcomm PCIe controller driver:
- Add qcom SAR2130P DT binding with an additional clock (Dmitry
Baryshkov)
- Enable MSI interrupts if 'global' IRQ is supported, since a
previous commit unintentionally masked them (Manivannan Sadhasivam)
- Move endpoint controller cleanups that depend on refclk from the
host to the notifier that tells us the host has deasserted PERST#,
when refclk should be valid (Manivannan Sadhasivam)
- Add DT binding and driver support for IPQ9574, with Synopsys IP
v5.80a and Qcom IP 1.27.0 (devi priya)
- Move the OPP "operating-points-v2" table from the
qcom,pcie-sm8450.yaml DT binding to qcom,pcie-common.yaml, where it
can be used by other Qcom platforms (Qiang Yu)
- Add 'global' SPI interrupt for events like link-up, link-down to
qcom,pcie-x1e80100 DT binding so we can start enumeration when the
link comes up (Qiang Yu)
- Disable ASPM L0s for qcom,pcie-x1e80100 since the PHY is not tuned
to support this (Qiang Yu)
- Add ops_1_21_0 for SC8280X family SoC, which doesn't use the
'iommu-map' DT property and doesn't need BDF-to-SID translation
(Qiang Yu)
Rockchip PCIe controller driver:
- Define ROCKCHIP_PCIE_AT_SIZE_ALIGN to replace magic 256 endpoint
.align value (Damien Le Moal)
- When unmapping an endpoint window, compute the region index instead
of searching for it, and verify that the address was mapped (Damien
Le Moal)
- When mapping an endpoint window, verify that the address hasn't
been mapped already (Damien Le Moal)
- Implement pci_epc_ops.align_addr() for rockchip-ep (Damien Le Moal)
- Fix MSI IRQ data mapping to observe the alignment constraint, which
fixes intermittent page faults in memcpy_toio() and memcpy_fromio()
(Damien Le Moal)
- Rename rockchip_pcie_parse_ep_dt() to
rockchip_pcie_ep_get_resources() for consistency with similar DT
interfaces (Damien Le Moal)
- Skip the unnecessary link train in rockchip_pcie_ep_probe() and do
it only in the endpoint start operation (Damien Le Moal)
- Implement pci_epc_ops.stop_link() to disable link training and
controller configuration (Damien Le Moal)
- Attempt link training at 5 GT/s when both partners support it
(Damien Le Moal)
- Add a handler for PERST# signal so we can detect host-initiated
resets and start link training after PERST# is deasserted (Damien
Le Moal)
Synopsys DesignWare PCIe controller driver:
- Clear outbound address on unmap so dw_pcie_find_index() won't match
an ATU index that was already unmapped (Damien Le Moal)
- Use of_property_present() instead of of_property_read_bool() when
testing for presence of non-boolean DT properties (Rob Herring)
- Advertise 1MB size if endpoint supports Resizable BARs, which was
inadvertently lost in v6.11 (Niklas Cassel)
TI J721E PCIe driver:
- Add PCIe support for J722S SoC (Siddharth Vadapalli)
- Delay PCIE_T_PVPERL_MS (100 ms), not just PCIE_T_PERST_CLK_US (100
us), before deasserting PERST# to ensure power and refclk are
stable (Siddharth Vadapalli)
TI Keystone PCIe controller driver:
- Set the 'ti,keystone-pcie' mode so v3.65a devices work in Root
Complex mode (Kishon Vijay Abraham I)

f2fs-for-6.13-rc1
This series introduces a device aliasing feature where user can carve out
partitions but reclaim the space back by deleting aliased file in root dir.
In addition to that, there're numerous minor bug fixes in zoned device support,
checkpoint=disable, extent cache management, fiemap, and lazytime mount option.
The full list of noticeable changes can be found below.
Enhancement:
- introduce device aliasing file
- add stats in debugfs to show multiple devices
- add a sysfs node to limit max read extent count per-inode
- modify f2fs_is_checkpoint_ready logic to allow more data to be written with the CP disable
- decrease spare area for pinned files for zoned devices
Bug fix:
- Revert "f2fs: remove unreachable lazytime mount option parsing"
- adjust unusable cap before checkpoint=disable mode
- fix to drop all discards after creating snapshot on lvm device
- fix to shrink read extent node in batches
- fix changing cursegs if recovery fails on zoned device

Pull f2fs updates from Jaegeuk Kim:
"This series introduces a device aliasing feature where user can carve
out partitions but reclaim the space back by deleting aliased file in
root dir.
In addition to that, there're numerous minor bug fixes in zoned device
support, checkpoint=disable, extent cache management, fiemap, and
lazytime mount option. The full list of noticeable changes can be
found below.
Enhancements:
- introduce device aliasing file
- add stats in debugfs to show multiple devices
- add a sysfs node to limit max read extent count per-inode
- modify f2fs_is_checkpoint_ready logic to allow more data to be
written with the CP disable
- decrease spare area for pinned files for zoned devices
Fixes:
- Revert "f2fs: remove unreachable lazytime mount option parsing"
- adjust unusable cap before checkpoint=disable mode
- fix to drop all discards after creating snapshot on lvm device
- fix to shrink read extent node in batches
- fix changing cursegs if recovery fails on zoned device
- fix to adjust appropriate length for fiemap
- fix fiemap failure issue when page size is 16KB
- fix to avoid forcing direct write to use buffered IO on inline_data
inode
- fix to map blocks correctly for direct write
- fix to account dirty data in __get_secs_required()
- fix null-ptr-deref in f2fs_submit_page_bio()
- fix inconsistent update of i_blocks in release_compress_blocks and

f2fs: add a sysfs node to limit max read extent count per-inode
Quoted:
"at this time, there are still 1086911 extent nodes in this zombie
extent tree that need to be cleaned up.
crash_arm64_sprd_v8.0.3++> extent_tree.node_cnt ffffff80896cc500
node_cnt = {
counter = 1086911
},
"
As reported by Xiuhong, there will be a huge number of extent nodes
in extent tree, it may potentially cause:
- slab memory fragments
- extreme long time shrink on extent tree
- low mapping efficiency
Let's add a sysfs node to limit max read extent count for each inode,
by default, value of this threshold is 10240, it can be updated
according to user's requirement.

soc: driver updates for 6.12
Nothing particular important in the SoC driver updates, just the usual
improvements to for drivers/soc and a couple of subsystems that don't
fit anywhere else:
- The largest set of updates is for Qualcomm SoC drivers, extending the
set of supported features for additional SoCs in the QSEECOM, LLCC
and socinfo drivers.a
- The ti_sci firmware driver gains support for power managment
- The drivers/reset subsystem sees a rework of the microchip
sparx5 and amlogic reset drivers to support additional chips,
plus a few minor updates on other platforms
- The SCMI firmware interface driver gains support for two protocol
extensions, allowing more flexible use of the shared memory area
and new DT binding properties for configurability.
- Mediatek SoC drivers gain support for power managment on the MT8188
SoC and a new driver for DVFS.
- The AMD/Xilinx ZynqMP SoC drivers gain support for system reboot
and a few bugfixes
- The Hisilicon Kunpeng HCCS driver gains support for configuring
lanes through sysfs
Finally, there are cleanups and minor fixes for drivers/soc, drivers/bus,
and drivers/memory, including changing back the .remove_new callback
to .remove, as well as a few other updates for freescale (powerpc)
soc drivers, NXP i.MX soc drivers, cznic turris platform driver, memory
controller drviers, TI OMAP SoC drivers, and Tegra firmware drivers

spi: Updates for v6.13
The only real core work we've got this time around is the completion of
the transition to the new host/target naming for the core APIs, Kconfig
still needs doing but that's a lot less invasive. Otherwise the big
changes are the new drivers that have been added:
- Completion of the conversion to spi_alloc_host()/_target() and
removal of the old naming.
- Cleanups for Rockchip drivers, these brought in a new logging helper
in the driver core for warnings during probe.
- Support for configuration of the word delay via spidev_test.
- Support for AMD HID2 controllers, Apple SPI controller and Realtek
SPI-NAND controllers.
The Rockchip cleanups

There are limitations involving generic netlink due to the multiplexing that is done, but it's no worse that what we currently have. As usual, more information can be found in the commit message. - Deprecate /sys/fs/selinux/user We removed the only known userspace use of this back in 2020 and now that several years have elapsed we're starting down the path of deprecating it in the kernel. - Cleanup the build under scripts/selinux A couple of patches to move the genheaders tool under security/selinux and correct our usage of kernel headers in the tools located under scripts/selinux. While these changes originated out of an effort to build Linux on different systems, they are arguably the right thing to do regardless. - Minor code cleanups and style fixes Not much to say here, two minor cleanup patches that came out of the netlink xperms work * tag 'selinux-pr-20241112' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux: selinux: Deprecate /sys/fs/selinux/user selinux: apply clang format to security/selinux/nlmsgtab.c selinux: streamline selinux_nlmsg_lookup() selinux: Add netlink xperm support selinux: move genheaders to security/selinux/ selinux: do not include <linux/*.h> headers from host programs |

PCI: Add 'reset_subordinate' to reset hierarchy below bridge
The "bus" and "cxl_bus" reset methods reset a device by asserting Secondary Bus Reset on the bridge leading to the device. These only work if the device is the only device below the bridge. Add a sysfs 'reset_subordinate' attribute on bridges that can assert Secondary Bus Reset regardless of how many devices are below the bridge. This resets all the devices below a bridge in a single command, including the locking and config space save/restore that reset methods normally do. This may be the only way to reset devices that don't support other reset methods (ACPI, FLR, PM reset, etc).

block: enable passthrough command statistics
Applications using the passthrough interfaces for IO want to continue seeing the disk stats. These requests had been fenced off from this block layer feature. While the block layer doesn't necessarily know what a passthrough command does, we do know the data size and direction, which is enough to account for the command's stats. Since tracking these has the potential to produce unexpected results, the passthrough stats are locked behind a new queue flag that needs to be enabled with the /sys/block/<dev>/queue/iostats_passthrough attribute.

The active mode is determined primarily by checking the speed of the enumerated USB device. When USB Power Delivery is supported, the active USB mode should be always the mode that was used with the Enter_USB Message, regardless of the result of the USB enumeration.

Add support for frame-based frame format, which can be used to support multiple formats like H264 or H265, in addition to MJPEG and YUV frames. The frame-based format is set to H264 by default, but it can be updated to other formats by modifying the GUID through the guid configfs attribute. Different structures are used for all three formats, as H264 has a different structure compared to MJPEG and uncompressed formats. These structures will be passed to the frame make function based on the active format, using a common frame structure with additional parameters needed only for frame-based formats. These parameters are handled at runtime in the UVC driver.

spi: intel: Add protected and locked attributes
The manufacturing access to the PCH/SoC SPI device is traditionally performed via userspace driver accessing registers via /dev/mem but due to security concerns /dev/mem access is being much restricted, hence the reason for utilizing dedicated Intel PCH/SoC SPI controller driver, which is already implemented in the Linux kernel. Intel PCH/SoC SPI controller protects the flash storage via two mechanisms one is the via region protection registers and second via BIOS lock. The BIOS locks only the BIOS regions usually 0 and/or 6. The device always boots with BIOS lock set, but during manufacturing the BIOS lock has to be lifted in order to enable the write access. This can be done by passing "writeable=1" in the command line when the driver is loaded. This "locked" state is exposed through new sysfs attributes (intel_spi_locked, intel_spi_bios_locked). Second, also the region protection status is exposed via sysfs attribute (intel_spi_protected) as the manufacturing will need the both files in order to validate that the device is properly sealed.

f2fs-6.12-rc1
In this series, the main changes include 1) converting major IO paths to use
folio, and 2) adding various knobs to control GC more flexibly for Zoned
devices. In addition, there are several patches to address corner cases of
atomic file operations and better support for file pinning on zoned device.
Enhancement:
- add knobs to tune foreground/background GCs for Zoned devices
- convert IO paths to use folio
- reduce expensive checkpoint trigger frequency
- allow F2FS_IPU_NOCACHE for pinned file
- forcibly migrate to secure space for zoned device file pinning
- get rid of buffer_head use
- add write priority option based on zone UFS
- get rid of online repair on corrupted directory
Bug fix:
- fix to don't panic system for no free segment fault injection
- fix to don't set SB_RDONLY in f2fs_handle_critical_error()
- avoid unused block when dio write in LFS mode
- compress: don't redirty sparse cluster during {,de}compress
- check discard support for conventional zones
- atomic: prevent atomic file from being dirtied before commit
- atomic: fix to check atomic_file in f2fs ioctl interfaces
- atomic: fix to forbid dio in atomic_file
- atomic: fix to truncate pagecache before on-disk metadata truncation
- atomic: create COW inode from parent dentry
- atomic: fix to avoid racing w/ GC
- atomic: require FMODE_WRITE for atomic write ioctls
- fix to wait page writeback before setting gcing flag
- fix to avoid racing in between read and OPU dio write, dio completion
- fix several potential integer overflows in file offsets and dir_block_index
- fix to avoid use-after-free in f2fs_stop_gc_thread()
As usual, there are several code clean-ups and refactorings.

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Wait for device readiness after reset by polling Vendor ID and
looking for Configuration RRS instead of polling the Command
register and looking for non-error completions, to avoid hardware
retries done for RRS on non-Vendor ID reads (Bjorn Helgaas)
- Rename CRS Completion Status to RRS ('Request Retry Status') to
match PCIe r6.0 spec usage (Bjorn Helgaas)
- Clear LBMS bit after a manual link retrain so we don't try to
retrain a link when there's no downstream device anymore (Maciej W.
Rozycki)
- Revert to the original link speed after retraining fails instead of
leaving it restricted to 2.5GT/s, so a future device has a chance
to use higher speeds (Maciej W. Rozycki)
- Wait for each level of downstream bus, not just the first, to
become accessible before restoring devices on that bus (Ilpo
Järvinen)
- Add ARCH_PCI_DEV_GROUPS so s390 can add its own attribute_groups
without having to stomp on the core's pdev->dev.groups (Lukas
Wunner)

- Export pcim_request_region(), a managed counterpart of
pci_request_region(), for use by drivers (Philipp Stanner)

(Philipp Stanner)
- Request the PCI BAR used by xboxvideo (Philipp Stanner)
- Request and map drm/ast BARs with pcim_iomap_region() (Philipp
Stanner)
MSI:
- Add MSI_FLAG_NO_AFFINITY flag for devices that mux MSIs onto a
single IRQ line and cannot set the affinity of each MSI to a
specific CPU core (Marek Vasut)
- Use MSI_FLAG_NO_AFFINITY and remove unnecessary .irq_set_affinity()
implementations in aardvark, altera, brcmstb, dwc, mediatek-gen3,
mediatek, mobiveil, plda, rcar, tegra, vmd, xilinx-nwl,
xilinx-xdma, and xilinx drivers to avoid 'IRQ: set affinity failed'
warnings (Marek Vasut)
Power management:
- Add pwrctl support for ATH11K inside the WCN6855 package (Konrad
Dybcio)
PCI device hotplug:
- Remove unnecessary hpc_ops struct from shpchp (ngn)
- Check for PCI_POSSIBLE_ERROR(), not 0xffffffff, in cpqphp
(weiyufeng)
Virtualization:
- Mark Creative Labs EMU20k2 INTx masking as broken (Alex Williamson)
- Add an ACS quirk for Qualcomm SA8775P, which doesn't advertise ACS
but does provide ACS-like features (Subramanian Ananthanarayanan)
IOMMU:

which uses the function 0 Requester ID (WangYuli)
NPEM:
- Add Native PCIe Enclosure Management (NPEM) support for sysfs
control of NVMe RAID storage indicators (ok/fail/locate/
rebuild/etc) (Mariusz Tkaczyk)
- Add support for the ACPI _DSM PCIe SSD status LED management, which
is functionally similar to NPEM but mediated by platform firmware
(Mariusz Tkaczyk)
Device trees:

clocks (Krzysztof Kozlowski)
Altera PCIe controller driver:
- Convert altera DT bindings from text to YAML (Matthew Gerlach)

- Use the 'bridge' reset method if described in the DT (Jim Quinlan)
- Use the 'swinit' reset method if described in the DT (Jim Quinlan)
- Add 'has_phy' so the existence of a 'rescal' reset controller
doesn't imply software control of it (Jim Quinlan)
- Add support for many inbound DMA windows (Jim Quinlan)
- Rename SoC 'type' to 'soc_base' express the fact that SoCs come in
families of multiple similar devices (Jim Quinlan)
- Add Broadcom 7712 DT description and driver support (Jim Quinlan)
- Sort enums, pcie_offsets[], pcie_cfg_data, .compatible strings for
maintainability (Bjorn Helgaas)

- Fix i.MX8MP Endpoint occasional failure to trigger MSI by enforcing
outbound alignment requirement (Richard Zhu)

statements (Frank Li)
- Manage core reset by using SoC-specific callbacks instead of switch
statements (Frank Li)
- Expand comments for erratum ERR010728 workaround (Frank Li)
- Use generic PHY APIs to configure mode, speed, and submode, which
is harmless for devices that implement their own internal PHY
management and don't set the generic imx_pcie->phy (Frank Li)
- Add i.MX8Q (i.MX8QM, i.MX8QXP, and i.MX8DXL) DT binding and driver
Root Complex support (Richard Zhu)
Freescale Layerscape PCIe controller driver:
- Replace layerscape-pcie DT binding compatible fsl,lx2160a-pcie with

to address a DT checker warning (Frank Li)
- Change layerscape-pcie DT binding 'fsl,pcie-scfg' to phandle-array
(Frank Li)

deasserted to partially avoid the problem that the endpoint SoC
crashes when accessing things when Refclk is absent (Manivannan
Sadhasivam)

Babu Chinta Venkata)
- Pass domain number to pci_bus_release_domain_nr() explicitly to
avoid a NULL pointer dereference (Manivannan Sadhasivam)
Renesas R-Car PCIe controller driver:

ALong with the usual shower of singleton patches, notable patch series in
this pull request are:
"Align kvrealloc() with krealloc()" from Danilo Krummrich. Adds
consistency to the APIs and behaviour of these two core allocation
functions. This also simplifies/enables Rustification.
"Some cleanups for shmem" from Baolin Wang. No functional changes - mode
code reuse, better function naming, logic simplifications.
"mm: some small page fault cleanups" from Josef Bacik. No functional
changes - code cleanups only.
"Various memory tiering fixes" from Zi Yan. A small fix and a little
cleanup.
"mm/swap: remove boilerplate" from Yu Zhao. Code cleanups and
simplifications and .text shrinkage.
"Kernel stack usage histogram" from Pasha Tatashin and Shakeel Butt. This
is a feature, it adds new feilds to /proc/vmstat such as
$ grep kstack /proc/vmstat
kstack_1k 3
kstack_2k 188
kstack_4k 11391
kstack_8k 243
kstack_16k 0
which tells us that 11391 processes used 4k of stack while none at all
used 16k. Useful for some system tuning things, but partivularly useful
for "the dynamic kernel stack project".
"kmemleak: support for percpu memory leak detect" from Pavel Tikhomirov.
Teaches kmemleak to detect leaksage of percpu memory.
"mm: memcg: page counters optimizations" from Roman Gushchin. "3
independent small optimizations of page counters".
"mm: split PTE/PMD PT table Kconfig cleanups+clarifications" from David
Hildenbrand. Improves PTE/PMD splitlock detection, makes powerpc/8xx work
correctly by design rather than by accident.
"mm: remove arch_make_page_accessible()" from David Hildenbrand. Some
folio conversions which make arch_make_page_accessible() unneeded.
"mm, memcg: cg2 memory{.swap,}.peak write handlers" fro David Finkel.
Cleans up and fixes our handling of the resetting of the cgroup/process
peak-memory-use detector.
"Make core VMA operations internal and testable" from Lorenzo Stoakes.
Rationalizaion and encapsulation of the VMA manipulation APIs. With a
view to better enable testing of the VMA functions, even from a
userspace-only harness.
"mm: zswap: fixes for global shrinker" from Takero Funaki. Fix issues in
the zswap global shrinker, resulting in improved performance.
"mm: print the promo watermark in zoneinfo" from Kaiyang Zhao. Fill in
some missing info in /proc/zoneinfo.
"mm: replace follow_page() by folio_walk" from David Hildenbrand. Code
cleanups and rationalizations (conversion to folio_walk()) resulting in
the removal of follow_page().
"improving dynamic zswap shrinker protection scheme" from Nhat Pham. Some
tuning to improve zswap's dynamic shrinker. Significant reductions in
swapin and improvements in performance are shown.
"mm: Fix several issues with unaccepted memory" from Kirill Shutemov.
Improvements to the new unaccepted memory feature,
"mm/mprotect: Fix dax puds" from Peter Xu. Implements mprotect on DAX
PUDs. This was missing, although nobody seems to have notied yet.
"Introduce a store type enum for the Maple tree" from Sidhartha Kumar.
Cleanups and modest performance improvements for the maple tree library
code.
"memcg: further decouple v1 code from v2" from Shakeel Butt. Move more
cgroup v1 remnants away from the v2 memcg code.
"memcg: initiate deprecation of v1 features" from Shakeel Butt. Adds
various warnings telling users that memcg v1 features are deprecated.
"mm: swap: mTHP swap allocator base on swap cluster order" from Chris Li.
Greatly improves the success rate of the mTHP swap allocation.
"mm: introduce numa_memblks" from Mike Rapoport. Moves various disparate
per-arch implementations of numa_memblk code into generic code.
"mm: batch free swaps for zap_pte_range()" from Barry Song. Greatly
improves the performance of munmap() of swap-filled ptes.
"support large folio swap-out and swap-in for shmem" from Baolin Wang.
With this series we no longer split shmem large folios into simgle-page
folios when swapping out shmem.
"mm/hugetlb: alloc/free gigantic folios" from Yu Zhao. Nice performance
improvements and code reductions for gigantic folios.
"support shmem mTHP collapse" from Baolin Wang. Adds support for
khugepaged's collapsing of shmem mTHP folios.

flags are now folio flags, so the page-based flags and their
accessors/mutators can be removed.
"mm: store zero pages to be swapped out in a bitmap" from Usama Arif. An
optimization which permits us to avoid writing/reading zero-filled zswap
pages to backing store.

Pull random number generator updates from Jason Donenfeld:
"Originally I'd planned on sending each of the vDSO getrandom()
architecture ports to their respective arch trees. But as we started
to work on this, we found lots of interesting issues in the shared
code and infrastructure, the fixes for which the various archs needed
to base their work.
So in the end, this turned into a nice collaborative effort fixing up
issues and porting to 5 new architectures -- arm64, powerpc64,
powerpc32, s390x, and loongarch64 -- with everybody pitching in and
commenting on each other's code. It was a fun development cycle.
This contains:
- Numerous fixups to the vDSO selftest infrastructure, getting it
running successfully on more platforms, and fixing bugs in it.
- Additions to the vDSO getrandom & chacha selftests. Basically every
time manual review unearthed a bug in a revision of an arch patch,
or an ambiguity, the tests were augmented.
By the time the last arch was submitted for review, s390x, v1 of
the series was essentially fine right out of the gate.
- Fixes to the the generic C implementation of vDSO getrandom, to
build and run successfully on all archs, decoupling it from
assumptions we had (unintentionally) made on x86_64 that didn't
carry through to the other architectures.
- Port of vDSO getrandom to LoongArch64, from Xi Ruoyao and acked by
Huacai Chen.
- Port of vDSO getrandom to ARM64, from Adhemerval Zanella and acked
by Will Deacon.
- Port of vDSO getrandom to PowerPC, in both 32-bit and 64-bit
varieties, from Christophe Leroy and acked by Michael Ellerman.
- Port of vDSO getrandom to S390X from Heiko Carstens, the arch
maintainer.
While it'd be natural for there to be things to fix up over the course
of the development cycle, these patches got a decent amount of review
from a fairly diverse crew of folks on the mailing lists, and, for the
most part, they've been cooking in linux-next, which has been helpful
for ironing out build issues.
In terms of architectures, I think that mostly takes care of the
important 64-bit archs with hardware still being produced and running
production loads in settings where vDSO getrandom is likely to help.
Arguably there's still RISC-V left, and we'll see for 6.13 whether
they find it useful and submit a port"

zram: introduce algorithm_params device attribute
This attribute is used to setup compression algorithms' parameters, so we can tweak algorithms' characteristics. At this point only 'level' is supported (to be extended in the future). Each call sets up parameters for one particular algorithm, which should be specified either by the algorithm's priority or algo name. This is expected to be called after corresponding algorithm is selected via comp_algorithm or recomp_algorithm. echo "priority=0 level=1" > /sys/block/zram0/algorithm_params or echo "algo=zstd level=1" > /sys/block/zram0/algorithm_params Link: https://lkml.kernel.org/r/20240902105656.1383858-16-senozhatsky@chromium.org Signed-off-by: Sergey Senozhatsky <senozhatsky@chromium.org> Cc: Minchan Kim <minchan@kernel.org> Cc: Nick Terrell <terrelln@fb.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> |

PCI/NPEM: Add _DSM PCIe SSD status LED management
The PCIe SSD Status LED Management _DSM defined in PCI Firmware Spec r3.3 sec 4.7 provides a way to manage LEDs via ACPI. The design is similar to NPEM defined in PCIe Base Specification r6.1 sec 6.28: - Both standards are indication oriented, - _DSM supported bits correspond to NPEM capability register bits, - _DSM control bits correspond to NPEM control register bits. _DSM does not support enclosure-specific indications or the special NPEM commands NPEM_ENABLE and NPEM_RESET. _DSM is implemented as a second backend in NPEM driver. The backend used is logged with info priority. The same sysfs interface is used for both NPEM and _DSM. According to spec, _DSM has higher priority, and availability of _DSM in not limited to devices with NPEM support. The Dell implementation of DSM uses acpi ipmi, which may not be available immediately (in fact it may take up to 10s for this interface to be available). It can determine if DSM is supported (GET_SUPPORTED_STATES_DSM is working) but it cannot serve GET_STATE_DSM or SET_STATE_DSM commands in this time. From userspace application perspective (primarily configured by systemd service) it is better to have not working but configured interface rather than have it available after few seconds. For that reason, npem->active_indications cache is now loaded lazily, i.e. any GET or SET request want cache to be updated if it is not done yet.

PCI/NPEM: Add Native PCIe Enclosure Management support
Native PCIe Enclosure Management (NPEM, PCIe r6.1 sec 6.28) allows managing LEDs in storage enclosures. NPEM is indication oriented and it does not give direct access to LEDs. Although each indication *could* represent an individual LED, multiple indications could also be represented as a single, multi-color LED or a single LED blinking in a specific interval. The specification leaves that open. Each enabled indication (capability register bit on) is represented as a ledclass_dev which can be controlled through sysfs. For every ledclass device only 2 brightness states are allowed: LED_ON (1) or LED_OFF (0). This corresponds to the NPEM control register (Indication bit on/off). Ledclass devices appear in sysfs as child devices (subdirectory) of PCI device which has an NPEM Extended Capability and indication is enabled in NPEM capability register. For example, these are LEDs created for pcieport "10000:02:05.0" on my setup: leds/ ├── 10000:02:05.0:enclosure:fail ├── 10000:02:05.0:enclosure:locate ├── 10000:02:05.0:enclosure:ok └── 10000:02:05.0:enclosure:rebuild They can be also found in "/sys/class/leds" directory. The parent PCIe device domain/bus/device/function address is used to guarantee uniqueness across leds subsystem. To enable/disable a "fail" indication, the "brightness" file can be edited: echo 1 > ./leds/10000:02:05.0:enclosure:fail/brightness echo 0 > ./leds/10000:02:05.0:enclosure:fail/brightness PCIe r6.1, sec 7.9.19.2 defines the possible indications. Multiple indications for same parent PCIe device can conflict and hardware may update them when processing new request. To avoid issues, driver refresh all indications by reading back control register. This driver expects to be the exclusive NPEM extended capability manager. It waits up to 1 second after imposing new request, it doesn't verify if controller is busy before write, and it assumes the mutex lock gives protection from concurrent updates. If _DSM LED management is available, we assume the platform may be using NPEM for its own purposes (see PCI Firmware Spec r3.3 sec 4.7), so the driver does not use NPEM. A future patch will add _DSM support; an info message notes whether NPEM or _DSM is being used. NPEM is a PCIe extended capability so it should be registered in pcie_init_capabilities() but it is not possible due to LED dependency. The parent pci_device must be added earlier for led_classdev_register() to be successful. NPEM does not require configuration on kernel side, so it is safe to register LED devices later.

power: supply: "usb_type" property may be written to
According to Documentation/ABI/testing/sysfs-class-power the "usb_type" property is Read-Only. For power-supplies which consume USB power such as battery charger chips, this is correct. But the UCS1002 USB Port Power Controller driver which is a driver for a chip which is a power-source for USB-A charging ports "usb_type" is actually writable to configure the type of USB charger emulated by the USB-A port. Adjust the docs and the power_supply_sysfs.c code to adjust for this new writeable use of "usb_type": 1. Update Documentation/ABI/testing/sysfs-class-power to document that "usb_type" may be writable 2. Change the power_supply_attr type in power_supply_sysfs.c from POWER_SUPPLY_ATTR() into POWER_SUPPLY_ENUM_ATTR() so that the various usb_type string values from POWER_SUPPLY_TYPE_TEXT[] such as e.g. "SDP" and "USB_PD" can be written to the "usb_type" attribute instead of only accepting integer values.

IIO: 1st set of new device support, features and cleanup for 6.12
Includes a merge of spi-mos-config branch from spi.git that brings support needed for the AD4000 driver. Lots of new device support this time including 9 new drivers and substantial changes to add new support to several more. New device support ------------------ Given we have a lot of new support, I've subcategorized them: Substantial changes, or new driver ********************************** adi,ad4000 - New driver for this high speed ADC. adi,ad4695 - New driver supporting AD4690, AD4696, AD4697 and AD4698 ADCs. - Follow up series added triggered buffer support. adi,ad7380 - Add support for single ended parts, AD7386, ADC7387, AD7388 and -4 variants. (driver previously only support differential parts). These variants have an additional front end MUX so only half the channels can be sampled efficiently. adi,ad9467 - Refactor and extend driver to support ad9643, ad9449 and ad9652 high speed ADCs. adi,adxl380 - New driver for this low power accelerometer. adi,ltc2664 - New driver supporting LTC2664 and LTC2672 DACs. microchip,pac1921 - New driver for this power/current monitor chip. rohm,bh1745 - New driver for this RGBC colour sensor. rohm,bu27034anuc - The original bu27034 was canceled before mass production, so the driver is modified to support the BU27034ANUC which had some significant differences. DT compatible changed to avoid chance of old driver ever binding to real hardware. sciosense,ens210 - New driver for ens210, ens210a, ens211, ens212, ens213a, and ens215 temperature and humidity sensors (all register compatible up to some conversion time differences) sensiron,sdp500 - New driver for this differential pressure sensor. tyhx,hx9023s - New driver to support this capacitive proximity sensor. Minor changes to support new devices ************************************ adi,adf4377 - Add support for the single output adf4378. kionix,kxcjk-1013 - Add support for KX022-1020 accelerometer (binding and ID table only) liteon,ltrf216a - Add support for ltr-308. A few minor differences in features set rockchip,saradc - Add ID for rk3576-saradc sensortek,stk3310 - Add ID for stk3013 proximity sensor which (despite documentation) has an ambient light sensor and is compatible with existing parts. Documentation updates --------------------- Generalize ABI docs for shunt resistor attribute Improve calibscale and calibbias related documentation. A couple of follow up patches to resolve duplicate documentation that resulted. New core features ----------------- backend - Add option for debugfs - useful for test pattern control - Use this for both adi-axi-adc and adi-axi-dac trigger suspend - Add functions to allow triggers to be suspended. This avoids problems when a device enters suspend to idle with a sysfs trigger. Use it for now in the bmi323 only. New driver features ------------------- adi,ad7192 - Add option to be a clock provider (+ additional clock config options) adi,ad7380 - Add documentation for this fairly new driver. adi,ad9461 - Provide control of test modes and backend validation blocks used to identify problems (via debugfs) adi,ad9739 - Add backend debugfs and docs for what is provided via adi-axi-dac avago,apds9960 - Add proximity and gesture calibration offset control bosch,bmp280 - Triggered buffer support including adding raw+scale output for sysfs. liteon,ltr390 - Add configuration of integration time and scale. stm,dfsdm - Convert this SD modulator driver to backend framework and add support for channel scaling + modern channel bindings. Treewide cleanup ---------------- iio_dev->masklength: Making it private. - Provide access function to read the core compute channel mask length and a macro to iterate over elements in the active_scan_mask. - Enables marking masklength __private preventing drivers from writing it without triggering a build warning whilst minimizing overhead in what are typically hot paths. - Convert all drivers and finally mark it private. Merge conflicts resolved in drivers applied after this point. Constify regmap_bus - These are never modified, so mark them const. Core cleanup ------------ backend - A few late breaking bits of feedback (unused variable, error messages) dma-buffer - Namespace exports. core - Drop unused assignment. Driver cleanup -------------- adi,ad4695 - Fixing binding to reflect that common-mode-channel is a scalar. adi,ad7280a - Use __free(kfree) to simplify freeing of receive buffer. adi,ad7606 - Various dt-binding cleanup and improvements. - Fix oversampling related gpio handling. - Make polarity of standby gpio match documentation. - use guard() to simplify lock handling. adi,ad7768 - Use device_for_each_child_node_scoped() instead of fwnode equivalent. adi,ad7124 - Reduce SPI transfers by avoiding separate writes to different fields in the same register. - Start the ADC in idle mode. adi,adis - Drop ifdefs in favor of IS_ENABLED. adi,admv8818 - Fix wrong ABI docs. asahi-kasei,ak8975 - Drop a prefix free compatible accidentally added recently. aspeed,adc - Use of_property_present() instead of of_find_property() to see if the property is there or not. atmel,at91, - Use __free(kfree) to simplify freeing of channel related array. bosch,bma400 - Use __free(kfree) to simplify freeing a locally allocated string. bosch,bmc150 - Add missing mount-matrix binding docs. bosch,bme680 - Fix read/write to ensure multiple necessary sequential reads without device configuration change. - Drop unnecessary type casts and use more appropriate data types. - Drop some left over ACPI code as ACPI support was removed due to invalid IDs (and no known users). - Sort headers consistently. - Avoid unnecessary duplicate read and redundant read of gas config. - Use bulk reads to get calibration data. - Reorder allocation of IIO device to be prior to device init. - Add remaining read/write buffers to the union used already for all others. - Tidy up error checks for consistency of style, including dev_err_probe() - Bring the device startup procedure inline with the vendor code. - Reorder code so mode forcing is more obvious occurring where needed. - Tidy up data locality in reading functions so no magic data is stored in state structures just to get it across function calls. - Make a local lookup table static to avoid placing it on the stack. bosch,bmp280 - Fix BME280 regmap to not include registers it doesn't have. - Wait a little longer after config to allow for maximum possible necessary wait. - Reorganize headers. - Make conversion_time_max array static to avoid placing it on the stack. maxim,max1363 - Use __free(kfree) to simplify freeing transmission buffer. microchip,mcp3964 - Use devm_regulator_get_enable_read_voltage() microchip,mcp3911 - Use devm_regulator_get_enable_read_voltage() microchip,mcp4728 - Use devm_regulator_get_enable_read_voltage() microchip,mcp4922 - Use devm_regulator_get_enable_read_voltage() and devm_* to allow dropping of explicit remove() callback. onnn,noa1305 - Various tidy up. - Provide available scale values. - Make integration time configurable. - Fix up integration time look up (/2 error) ti,dac7311 - Check if spi_setup() succeeded. ti,tsc2046 - Use __free(kfree) to simplify freeing rx and tx buffers. - Use devm_regulator_get_enable_read_voltage() Various minor fixes not called out explicitly. -----BEGIN PGP SIGNATURE----- iQJFBAABCAAvFiEEbilms4eEBlKRJoGxVIU0mcT0FogFAmbHhnARHGppYzIzQGtl cm5lbC5vcmcACgkQVIU0mcT0FohpshAApFDoTkyYMa7x1r5WUZ/5j474319LvwDO /9UIDIgR8qSzR2fDYl+LR03ZWknsOXF4lfCrCf65zPaR/8bB7TsjD8A7uIPVAKDF Tu+nSgBworJcvokPzygtrjoor2u2LCXdZVurYrFggMZ833LY5HTotFDAB32wx3QM p7p7OU0LgAZ8VR+ykzkbwp9NjOSrgD2mD7emy7Enu4h/OzLzst0c15KkUaOpnSUZ 8R/+tz5lERrF+ACjWm+sWSe8ry2SkQppd8G8pSXyUM0uD2KO0I78FEpA3wUB2H++ wiki1cm1kOM/ljHbXn2tqp5s+A8p6d0/LOCZm9bUi9kmtP5J2ky2iZmpZPraO52d +jbnHh/GyvoyIzeZRJZtp9h4hWTPNV2pgvb5BHD7Fek5rxOXXBlulDd695Ygbfq5 vxiXYfN+ozVQk3/1mm0FwA34VZSoHADvzTxANQE9Vi99ywenpqJ5VYWQm/Bf0oHm HMH1sCcrmPHF9NOEUPV2uCanTQ20Q+OO89xOUBDGma1FKh6108wSont5c6GX/dKu sChUdllXSlNUR8VoiAYSFEP/U+gXnRE8Scxuk1Xx12RuKYpe0NNdRyRtj86kTU+1 e6gHY90NskQCSVvOiivvo/rNTO08EZND9V3pbD/2HxaFvM4zw/iJtNR49DLdTkpX DfiCl2BAbLw= =eXUA -----END PGP SIGNATURE----- Merge tag 'iio-for-6.12a' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-testing Jonathan writes: IIO: 1st set of new device support, features and cleanup for 6.12 Includes a merge of spi-mos-config branch from spi.git that brings support needed for the AD4000 driver.

usb: gadget: f_acm: make bInterfaceProtocol configurable
The bInterfaceProtocol is hardcoded to USB_CDC_ACM_PROTO_AT_V25TER. This
will lead to problems with ModemManger which will gladly try to probe
that port as a modem if the gadget also has a network function.
ModemManager will try to send AT commands to the ACM port. Make the
bInterfaceProtocol configurable. For this, track the number of instances
and only allow write to the property if there are no intances (yet).
This will also set bFunctionProtocol to the same value, see commit

[FAIL] No such clock, but __vdso_clock_gettime returned 22 On powerpc, a call to a VDSO function is not an ordinary C function call. Unlike several architectures which returns a negative error code in case of an error, powerpc sets CR[SO] and returns the error code as a positive value. Define and use a macro called VDSO_CALL() which takes a pointer to the function to call, the number of arguments and the arguments. Also update ABI vdso documentation to reflect this subtlety. Provide a specific version of VDSO_CALL() for powerpc that negates the error code on return when CR[SO] is set. Fixes: |

ABI: testing: sysfs-class-power: clarify charge_type documentation
The existing docs here are a bit vague. This reformats and rewords it, and is based upon the wording originally used by the dell-laptop driver battery documentation and also sysfs-class-power-wilco. The wording for "Long Life" and "Bypass" remain the same, because I'm unfamiliar with hardware that use them.

optee: probe RPMB device using RPMB subsystem
Adds support in the OP-TEE drivers (both SMC and FF-A ABIs) to probe and use an RPMB device via the RPMB subsystem instead of passing the RPMB frames via tee-supplicant in user space. A fallback mechanism is kept to route RPMB frames via tee-supplicant if the RPMB subsystem isn't available. The OP-TEE RPC ABI is extended to support iterating over all RPMB devices until one is found with the expected RPMB key already programmed.

iio: ABI: add missing calibbias attributes
There are a number of calibbias and calibbias_available attributes that

cpu/SMT: Enable SMT only if a core is online
If a core is offline then enabling SMT should not online CPUs of
this core. By enabling SMT, what is intended is either changing the SMT
value from "off" to "on" or setting the SMT level (threads per core) from a
lower to higher value.
On PowerPC the ppc64_cpu utility can be used, among other things, to
perform the following functions:
ppc64_cpu --cores-on # Get the number of online cores
ppc64_cpu --cores-on=X # Put exactly X cores online
ppc64_cpu --offline-cores=X[,Y,...] # Put specified cores offline
ppc64_cpu --smt={on|off|value} # Enable, disable or change SMT level
If the user has decided to offline certain cores, enabling SMT should
not online CPUs in those cores. This patch fixes the issue and changes
the behaviour as described, by introducing an arch specific function
topology_is_core_online(). It is currently implemented only for PowerPC.

f2fs: add write priority option based on zone UFS
Currently, we are using a mix of traditional UFS and zone UFS to support some functionalities that cannot be achieved on zone UFS alone. However, there are some issues with this approach. There exists a significant performance difference between traditional UFS and zone UFS. Under normal usage, we prioritize writes to zone UFS. However, in critical conditions (such as when the entire UFS is almost full), we cannot determine whether data will be written to traditional UFS or zone UFS. This can lead to significant performance fluctuations, which is not conducive to development and testing. To address this, we have added an option zlu_io_enable under sys with the following three modes: 1) zlu_io_enable == 0:Normal mode, prioritize writing to zone UFS; 2) zlu_io_enable == 1:Zone UFS only mode, only allow writing to zone UFS; 3) zlu_io_enable == 2:Traditional UFS priority mode, prioritize writing to traditional UFS.

Pull CXL updates from Dave Jiang:
"Core:
- A CXL maturity map has been added to the documentation to detail
the current state of CXL enabling.
It provides the status of the current state of various CXL features
to inform current and future contributors of where things are and
which areas need contribution.
- A notifier handler has been added in order for a newly created CXL
memory region to trigger the abstract distance metrics calculation.
This should bring parity for CXL memory to the same level vs
hotplugged DRAM for NUMA abstract distance calculation. The
abstract distance reflects relative performance used for memory
tiering handling.
- An addition for XOR math has been added to address the CXL DPA to
SPA translation.
CXL address translation did not support address interleave math
with XOR prior to this change.
Fixes:
- Fix to address race condition in the CXL memory hotplug notifier
- Add missing MODULE_DESCRIPTION() for CXL modules
- Fix incorrect vendor debug UUID define
Misc:
- A warning has been added to inform users of an unsupported
configuration when mixing CXL VH and RCH/RCD hierarchies
- The ENXIO error code has been replaced with EBUSY for inject poison
limit reached via debugfs and cxl-test support
- Moving the PCI config read in cxl_dvsec_rr_decode() to avoid
unnecessary PCI config reads
- A refactor to a common struct for DRAM and general media CXL
events"

Yu has a fix which I'll send along later via the hotfixes branch. - In the series "mm: Avoid possible overflows in dirty throttling" Jan Kara addresses a couple of issues in the writeback throttling code. These fixes are also targetted at -stable kernels. - Ryusuke Konishi's series "nilfs2: fix potential issues related to reserved inodes" does that. This should actually be in the mm-nonmm-stable tree, along with the many other nilfs2 patches. My bad. - More folio conversions from Kefeng Wang in the series "mm: convert to folio_alloc_mpol()" - Kemeng Shi has sent some cleanups to the writeback code in the series "Add helper functions to remove repeated code and improve readability of cgroup writeback" - Kairui Song has made the swap code a little smaller and a little faster in the series "mm/swap: clean up and optimize swap cache index". - In the series "mm/memory: cleanly support zeropage in vm_insert_page*(), vm_map_pages*() and vmf_insert_mixed()" David Hildenbrand has reworked the rather sketchy handling of the use of the zeropage in MAP_SHARED mappings. I don't see any runtime effects here - more a cleanup/understandability/maintainablity thing. - Dev Jain has improved selftests/mm/va_high_addr_switch.c's handling of higher addresses, for aarch64. The (poorly named) series is "Restructure va_high_addr_switch". - The core TLB handling code gets some cleanups and possible slight optimizations in Bang Li's series "Add update_mmu_tlb_range() to simplify code". - Jane Chu has improved the handling of our fake-an-unrecoverable-memory-error testing feature MADV_HWPOISON in the series "Enhance soft hwpoison handling and injection". - Jeff Johnson has sent a billion patches everywhere to add MODULE_DESCRIPTION() to everything. Some landed in this pull. - In the series "mm: cleanup MIGRATE_SYNC_NO_COPY mode", Kefeng Wang has simplified migration's use of hardware-offload memory copying. - Yosry Ahmed performs more folio API conversions in his series "mm: zswap: trivial folio conversions". - In the series "large folios swap-in: handle refault cases first", Chuanhua Han inches us forward in the handling of large pages in the swap code. This is a cleanup and optimization, working toward the end objective of full support of large folio swapin/out. - In the series "mm,swap: cleanup VMA based swap readahead window calculation", Huang Ying has contributed some cleanups and a possible fixlet to his VMA based swap readahead code. - In the series "add mTHP support for anonymous shmem" Baolin Wang has taught anonymous shmem mappings to use multisize THP. By default this is a no-op - users must opt in vis sysfs controls. Dramatic improvements in pagefault latency are realized. - David Hildenbrand has some cleanups to our remaining use of page_mapcount() in the series "fs/proc: move page_mapcount() to fs/proc/internal.h". - David also has some highmem accounting cleanups in the series "mm/highmem: don't track highmem pages manually". - Build-time fixes and cleanups from John Hubbard in the series "cleanups, fixes, and progress towards avoiding "make headers"". - Cleanups and consolidation of the core pagemap handling from Barry Song in the series "mm: introduce pmd|pte_needs_soft_dirty_wp helpers and utilize them". - Lance Yang's series "Reclaim lazyfree THP without splitting" has reduced the latency of the reclaim of pmd-mapped THPs under fairly common circumstances. A 10x speedup is seen in a microbenchmark. It does this by punting to aother CPU but I guess that's a win unless all CPUs are pegged. - hugetlb_cgroup cleanups from Xiu Jianfeng in the series "mm/hugetlb_cgroup: rework on cftypes". - Miaohe Lin's series "Some cleanups for memory-failure" does just that thing. - Is anyone reading this stuff? If so, email me! - Someone other than SeongJae has developed a DAMON feature in Honggyu Kim's series "DAMON based tiered memory management for CXL memory". This adds DAMON features which may be used to help determine the efficiency of our placement of CXL/PCIe attached DRAM. - DAMON user API centralization and simplificatio work in SeongJae Park's series "mm/damon: introduce DAMON parameters online commit function". - In the series "mm: page_type, zsmalloc and page_mapcount_reset()" David Hildenbrand does some maintenance work on zsmalloc - partially modernizing its use of pageframe fields. - Kefeng Wang provides more folio conversions in the series "mm: remove page_maybe_dma_pinned() and page_mkclean()". - More cleanup from David Hildenbrand, this time in the series "mm/memory_hotplug: use PageOffline() instead of PageReserved() for !ZONE_DEVICE". It "enlightens memory hotplug more about PageOffline() pages" and permits the removal of some virtio-mem hacks. - Barry Song's series "mm: clarify folio_add_new_anon_rmap() and __folio_add_anon_rmap()" is a cleanup to the anon folio handling in preparation for mTHP (multisize THP) swapin. - Kefeng Wang's series "mm: improve clear and copy user folio" implements more folio conversions, this time in the area of large folio userspace copying. - The series "Docs/mm/damon/maintaier-profile: document a mailing tool and community meetup series" tells people how to get better involved with other DAMON developers. From SeongJae Park. - A large series ("kmsan: Enable on s390") from Ilya Leoshkevich does that. - David Hildenbrand sends along more cleanups, this time against the migration code. The series is "mm/migrate: move NUMA hinting fault folio isolation + checks under PTL". - Jan Kara has found quite a lot of strangenesses and minor errors in the readahead code. He addresses this in the series "mm: Fix various readahead quirks". - SeongJae Park's series "selftests/damon: test DAMOS tried regions and {min,max}_nr_regions" adds features and addresses errors in DAMON's self testing code. - Gavin Shan has found a userspace-triggerable WARN in the pagecache code. The series "mm/filemap: Limit page cache size to that supported by xarray" addresses this. The series is marked cc:stable. - Chengming Zhou's series "mm/ksm: cmp_and_merge_page() optimizations and cleanup" cleans up and slightly optimizes KSM. - Roman Gushchin has separated the memcg-v1 and memcg-v2 code - lots of code motion. The series (which also makes the memcg-v1 code Kconfigurable) are "mm: memcg: separate legacy cgroup v1 code and put under config option" and "mm: memcg: put cgroup v1-specific memcg data under CONFIG_MEMCG_V1" - Dan Schatzberg's series "Add swappiness argument to memory.reclaim" adds an additional feature to this cgroup-v2 control file. - The series "Userspace controls soft-offline pages" from Jiaqi Yan permits userspace to stop the kernel's automatic treatment of excessive correctable memory errors. In order to permit userspace to monitor and handle this situation. - Kefeng Wang's series "mm: migrate: support poison recover from migrate folio" teaches the kernel to appropriately handle migration from poisoned source folios rather than simply panicing. - SeongJae Park's series "Docs/damon: minor fixups and improvements" does those things. - In the series "mm/zsmalloc: change back to per-size_class lock" Chengming Zhou improves zsmalloc's scalability and memory utilization. - Vivek Kasireddy's series "mm/gup: Introduce memfd_pin_folios() for pinning memfd folios" makes the GUP code use FOLL_PIN rather than bare refcount increments. So these paes can first be moved aside if they reside in the movable zone or a CMA block. - Andrii Nakryiko has added a binary ioctl()-based API to /proc/pid/maps for much faster reading of vma information. The series is "query VMAs from /proc/<pid>/maps". - In the series "mm: introduce per-order mTHP split counters" Lance Yang improves the kernel's presentation of developer information related to multisize THP splitting. - Michael Ellerman has developed the series "Reimplement huge pages without hugepd on powerpc (8xx, e500, book3s/64)". This permits userspace to use all available huge page sizes. - In the series "revert unconditional slab and page allocator fault injection calls" Vlastimil Babka removes a performance-affecting and not very useful feature from slab fault injection. -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQTTMBEPP41GrTpTJgfdBJ7gKXxAjgUCZp2C+QAKCRDdBJ7gKXxA joTkAQDvjqOoFStqk4GU3OXMYB7WCU/ZQMFG0iuu1EEwTVDZ4QEA8CnG7seek1R3 xEoo+vw0sWWeLV3qzsxnCA1BJ8cTJA8= =z0Lf -----END PGP SIGNATURE----- Merge tag 'mm-stable-2024-07-21-14-50' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Pull MM updates from Andrew Morton: - In the series "mm: Avoid possible overflows in dirty throttling" Jan Kara addresses a couple of issues in the writeback throttling code.

Some landed in this pull. - In the series "mm: cleanup MIGRATE_SYNC_NO_COPY mode", Kefeng Wang has simplified migration's use of hardware-offload memory copying. - Yosry Ahmed performs more folio API conversions in his series "mm: zswap: trivial folio conversions". - In the series "large folios swap-in: handle refault cases first", Chuanhua Han inches us forward in the handling of large pages in the swap code. This is a cleanup and optimization, working toward the end objective of full support of large folio swapin/out. - In the series "mm,swap: cleanup VMA based swap readahead window calculation", Huang Ying has contributed some cleanups and a possible fixlet to his VMA based swap readahead code. - In the series "add mTHP support for anonymous shmem" Baolin Wang has taught anonymous shmem mappings to use multisize THP. By default this is a no-op - users must opt in vis sysfs controls. Dramatic improvements in pagefault latency are realized. - David Hildenbrand has some cleanups to our remaining use of page_mapcount() in the series "fs/proc: move page_mapcount() to fs/proc/internal.h". - David also has some highmem accounting cleanups in the series "mm/highmem: don't track highmem pages manually". - Build-time fixes and cleanups from John Hubbard in the series "cleanups, fixes, and progress towards avoiding "make headers"". - Cleanups and consolidation of the core pagemap handling from Barry Song in the series "mm: introduce pmd|pte_needs_soft_dirty_wp helpers and utilize them". - Lance Yang's series "Reclaim lazyfree THP without splitting" has reduced the latency of the reclaim of pmd-mapped THPs under fairly common circumstances. A 10x speedup is seen in a microbenchmark. It does this by punting to aother CPU but I guess that's a win unless all CPUs are pegged. - hugetlb_cgroup cleanups from Xiu Jianfeng in the series "mm/hugetlb_cgroup: rework on cftypes". - Miaohe Lin's series "Some cleanups for memory-failure" does just that thing. - Someone other than SeongJae has developed a DAMON feature in Honggyu Kim's series "DAMON based tiered memory management for CXL memory". This adds DAMON features which may be used to help determine the efficiency of our placement of CXL/PCIe attached DRAM. - DAMON user API centralization and simplificatio work in SeongJae Park's series "mm/damon: introduce DAMON parameters online commit function". - In the series "mm: page_type, zsmalloc and page_mapcount_reset()" David Hildenbrand does some maintenance work on zsmalloc - partially modernizing its use of pageframe fields. - Kefeng Wang provides more folio conversions in the series "mm: remove page_maybe_dma_pinned() and page_mkclean()". - More cleanup from David Hildenbrand, this time in the series "mm/memory_hotplug: use PageOffline() instead of PageReserved() for !ZONE_DEVICE". It "enlightens memory hotplug more about PageOffline() pages" and permits the removal of some virtio-mem hacks. - Barry Song's series "mm: clarify folio_add_new_anon_rmap() and __folio_add_anon_rmap()" is a cleanup to the anon folio handling in preparation for mTHP (multisize THP) swapin. - Kefeng Wang's series "mm: improve clear and copy user folio" implements more folio conversions, this time in the area of large folio userspace copying. - The series "Docs/mm/damon/maintaier-profile: document a mailing tool and community meetup series" tells people how to get better involved with other DAMON developers. From SeongJae Park. - A large series ("kmsan: Enable on s390") from Ilya Leoshkevich does that. - David Hildenbrand sends along more cleanups, this time against the migration code. The series is "mm/migrate: move NUMA hinting fault folio isolation + checks under PTL". - Jan Kara has found quite a lot of strangenesses and minor errors in the readahead code. He addresses this in the series "mm: Fix various readahead quirks". - SeongJae Park's series "selftests/damon: test DAMOS tried regions and {min,max}_nr_regions" adds features and addresses errors in DAMON's self testing code. - Gavin Shan has found a userspace-triggerable WARN in the pagecache code. The series "mm/filemap: Limit page cache size to that supported by xarray" addresses this. The series is marked cc:stable. - Chengming Zhou's series "mm/ksm: cmp_and_merge_page() optimizations and cleanup" cleans up and slightly optimizes KSM. - Roman Gushchin has separated the memcg-v1 and memcg-v2 code - lots of code motion. The series (which also makes the memcg-v1 code Kconfigurable) are "mm: memcg: separate legacy cgroup v1 code and put under config option" and "mm: memcg: put cgroup v1-specific memcg data under CONFIG_MEMCG_V1" - Dan Schatzberg's series "Add swappiness argument to memory.reclaim" adds an additional feature to this cgroup-v2 control file. - The series "Userspace controls soft-offline pages" from Jiaqi Yan permits userspace to stop the kernel's automatic treatment of excessive correctable memory errors. In order to permit userspace to monitor and handle this situation. - Kefeng Wang's series "mm: migrate: support poison recover from migrate folio" teaches the kernel to appropriately handle migration from poisoned source folios rather than simply panicing. - SeongJae Park's series "Docs/damon: minor fixups and improvements" does those things. - In the series "mm/zsmalloc: change back to per-size_class lock" Chengming Zhou improves zsmalloc's scalability and memory utilization. - Vivek Kasireddy's series "mm/gup: Introduce memfd_pin_folios() for pinning memfd folios" makes the GUP code use FOLL_PIN rather than bare refcount increments. So these paes can first be moved aside if they reside in the movable zone or a CMA block. - Andrii Nakryiko has added a binary ioctl()-based API to /proc/pid/maps for much faster reading of vma information. The series is "query VMAs from /proc/<pid>/maps". - In the series "mm: introduce per-order mTHP split counters" Lance Yang improves the kernel's presentation of developer information related to multisize THP splitting. - Michael Ellerman has developed the series "Reimplement huge pages without hugepd on powerpc (8xx, e500, book3s/64)". This permits userspace to use all available huge page sizes. - In the series "revert unconditional slab and page allocator fault injection calls" Vlastimil Babka removes a performance-affecting and not very useful feature from slab fault injection. * tag 'mm-stable-2024-07-21-14-50' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm: (411 commits) mm/mglru: fix ineffective protection calculation mm/zswap: fix a white space issue mm/hugetlb: fix kernel NULL pointer dereference when migrating hugetlb folio mm/hugetlb: fix possible recursive locking detected warning mm/gup: clear the LRU flag of a page before adding to LRU batch mm/numa_balancing: teach mpol_to_str about the balancing mode mm: memcg1: convert charge move flags to unsigned long long alloc_tag: fix page_ext_get/page_ext_put sequence during page splitting lib: reuse page_ext_data() to obtain codetag_ref lib: add missing newline character in the warning message mm/mglru: fix overshooting shrinker memory mm/mglru: fix div-by-zero in vmpressure_calc_level() mm/kmemleak: replace strncpy() with strscpy() mm, page_alloc: put should_fail_alloc_page() back behing CONFIG_FAIL_PAGE_ALLOC mm, slab: put should_failslab() back behind CONFIG_SHOULD_FAILSLAB mm: ignore data-race in __swap_writepage hugetlbfs: ensure generic_hugetlb_get_unmapped_area() returns higher address than mmap_min_addr mm: shmem: rename mTHP shmem counters mm: swap_state: use folio_alloc_mpol() in __read_swap_cache_async() mm/migrate: putback split folios when numa hint migration fails ... |

New code for 6.11:
* Enable FITRIM on the realtime device.
* Introduce byte-based grant head log reservation tracking instead of
physical log location tracking.
This allows grant head to track a full 64 bit bytes space and hence
overcome the limit of 4GB indexing that has been present until now.
* Fixes
- xfs_flush_unmap_range() and xfs_prepare_shift() should consider RT extents
in the flush unmap range.
- Implement bounds check when traversing log operations during log replay.
- Prevent out of bounds access when traversing a directory data block.
- Prevent incorrect ENOSPC when concurrently performing file creation and
file writes.
- Fix rtalloc rotoring when delalloc is in use
* Cleanups
- Clean up I/O path inode locking helpers and the page fault handler.
- xfs: hoist inode operations to libxfs in anticipation of the metadata
inode directory feature, which maintains a directory tree of metadata
inodes. This will be necessary for further enhancements to the realtime
feature, subvolume support.
- Clean up some warts in the extent freeing log intent code.
- Clean up the refcount and rmap intent code before adding support for
realtime devices.
- Provide the correct email address for sysfs ABI documentation.

Networking changes for 6.11. Not much excitement - a handful of large
patchsets (devmem among them) did not make it in time.
Core & protocols
----------------
- Use local_lock in addition to local_bh_disable() to protect per-CPU
resources in networking, a step closer for local_bh_disable() not
to act as a big lock on PREEMPT_RT.
- Use flex array for netdevice priv area, ensure its cache alignment.
- Add a sysctl knob to allow user to specify a default rto_min at socket
init time. Bit of a big hammer but multiple companies were
independently carrying such patch downstream so clearly it's useful.
- Support scheduling transmission of packets based on CLOCK_TAI.
- Un-pin TCP TIMEWAIT timer to avoid it firing on CPUs later cordoned off
using cpusets.
- Support multiple L2TPv3 UDP tunnels using the same 5-tuple address.
- Allow configuration of multipath hash seed, to both allow synchronizing
hashing of two routers, and preventing partial accidental sync.
- Improve TCP compliance with RFC 9293 for simultaneous connect().
- Support sending NAT keepalives in IPsec ESP in UDP states. Userspace
IKE daemon had to do this before, but the kernel can better keep
track of it.
- Support sending supervision HSR frames with MAC addresses stored in
ProxyNodeTable when RedBox (i.e. HSR-SAN) is enabled.
- Introduce IPPROTO_SMC for selecting SMC when socket is created.
- Allow UDP GSO transmit from devices with no checksum offload.
- openvswitch: add packet sampling via psample, separating the sampled
traffic from "upcall" packets sent to user space for forwarding.
- nf_tables: shrink memory consumption for transaction objects.
Things we sprinkled into general kernel code
--------------------------------------------
- Power Sequencing subsystem (used by Qualcomm Bluetooth driver
for QCA6390).
- Add IRQ information in sysfs for auxiliary bus.
- Introduce guard definition for local_lock.
- Add aligned flavor of __cacheline_group_{begin, end}() markings for
grouping fields in structures.
BPF
---
- Notify user space (via epoll) when a struct_ops object is getting
detached/unregistered.
- Add new kfuncs for a generic, open-coded bits iterator.
- Enable BPF programs to declare arrays of kptr, bpf_rb_root, and
bpf_list_head.
- Support resilient split BTF which cuts down on duplication and makes
BTF as compact as possible WRT BTF from modules.
- Add support for dumping kfunc prototypes from BTF which enables both
detecting as well as dumping compilable prototypes for kfuncs.
- riscv64 BPF JIT improvements in particular to add 12-argument support
for BPF trampolines and to utilize bpf_prog_pack for the latter.
- Add the capability to offload the netfilter flowtable in XDP layer
through kfuncs.
Driver API
----------
- Allow users to configure IRQ tresholds between which automatic IRQ
moderation can choose.
- Expand Power Sourcing (PoE) status with power, class and failure
reason. Support setting power limits.
- Track additional RSS contexts in the core, make sure configuration
changes don't break them.
- Support IPsec crypto offload for IPv6 ESP and IPv4 UDP-encapsulated ESP
data paths.
- Support updating firmware on SFP modules.
Tests and tooling
-----------------
- mptcp: use net/lib.sh to manage netns.
- TCP-AO and TCP-MD5: replace debug prints used by tests with
tracepoints.
- openvswitch: make test self-contained (don't depend on OvS CLI tools).
Drivers
-------
- Ethernet high-speed NICs:
- Broadcom (bnxt):
- increase the max total outstanding PTP TX packets to 4
- add timestamping statistics support
- implement netdev_queue_mgmt_ops
- support new RSS context API
- Intel (100G, ice, idpf):
- implement FEC statistics and dumping signal quality indicators
- support E825C products (with 56Gbps PHYs)
- nVidia/Mellanox:

Merge tag 'net-next-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Jakub Kicinski:
"Not much excitement - a handful of large patchsets (devmem among them)
did not make it in time.
Core & protocols:
- Use local_lock in addition to local_bh_disable() to protect per-CPU
resources in networking, a step closer for local_bh_disable() not
to act as a big lock on PREEMPT_RT
- Use flex array for netdevice priv area, ensure its cache alignment
- Add a sysctl knob to allow user to specify a default rto_min at
socket init time. Bit of a big hammer but multiple companies were
independently carrying such patch downstream so clearly it's useful
- Support scheduling transmission of packets based on CLOCK_TAI
- Un-pin TCP TIMEWAIT timer to avoid it firing on CPUs later cordoned
off using cpusets
- Support multiple L2TPv3 UDP tunnels using the same 5-tuple address
- Allow configuration of multipath hash seed, to both allow
synchronizing hashing of two routers, and preventing partial
accidental sync
- Improve TCP compliance with RFC 9293 for simultaneous connect()
- Support sending NAT keepalives in IPsec ESP in UDP states.
Userspace IKE daemon had to do this before, but the kernel can
better keep track of it
- Support sending supervision HSR frames with MAC addresses stored in
ProxyNodeTable when RedBox (i.e. HSR-SAN) is enabled
- Introduce IPPROTO_SMC for selecting SMC when socket is created
- Allow UDP GSO transmit from devices with no checksum offload
- openvswitch: add packet sampling via psample, separating the
sampled traffic from "upcall" packets sent to user space for
forwarding
- nf_tables: shrink memory consumption for transaction objects
Things we sprinkled into general kernel code:
- Power Sequencing subsystem (used by Qualcomm Bluetooth driver for
QCA6390) [ Already merged separately - Linus ]
- Add IRQ information in sysfs for auxiliary bus
- Introduce guard definition for local_lock
- Add aligned flavor of __cacheline_group_{begin, end}() markings for
grouping fields in structures
BPF:
- Notify user space (via epoll) when a struct_ops object is getting
detached/unregistered
- Add new kfuncs for a generic, open-coded bits iterator
- Enable BPF programs to declare arrays of kptr, bpf_rb_root, and
bpf_list_head
- Support resilient split BTF which cuts down on duplication and
makes BTF as compact as possible WRT BTF from modules
- Add support for dumping kfunc prototypes from BTF which enables
both detecting as well as dumping compilable prototypes for kfuncs
- riscv64 BPF JIT improvements in particular to add 12-argument
support for BPF trampolines and to utilize bpf_prog_pack for the
latter
- Add the capability to offload the netfilter flowtable in XDP layer
through kfuncs
Driver API:
- Allow users to configure IRQ tresholds between which automatic IRQ
moderation can choose
- Expand Power Sourcing (PoE) status with power, class and failure
reason. Support setting power limits
- Track additional RSS contexts in the core, make sure configuration
changes don't break them
- Support IPsec crypto offload for IPv6 ESP and IPv4 UDP-encapsulated
ESP data paths
- Support updating firmware on SFP modules
Tests and tooling:
- mptcp: use net/lib.sh to manage netns
- TCP-AO and TCP-MD5: replace debug prints used by tests with
tracepoints
- openvswitch: make test self-contained (don't depend on OvS CLI
tools)
Drivers:
- Ethernet high-speed NICs:
- Broadcom (bnxt):
- increase the max total outstanding PTP TX packets to 4
- add timestamping statistics support
- implement netdev_queue_mgmt_ops
- support new RSS context API

soc: driver updates for 6.11
The updates to the mediatek, allwinner, ti, tegra, microchip, stm32, samsung, imx, zynq and amlogic platoforms are farily small maintenance changes, either addressing minor mistakes or enabling additional hardware. The qualcomm platform changes add a number of features and are larger than the other ones combined, introducing the use of linux/cleanup.h across several drivers, adding support for Snapdragon X1E and other SoCs in platform drivers, a new "protection domain mapper" driver, and a "shared memory bridge" driver. The cznic "turris omnia" router based on Marvell Armada gets a platform driver that talks to the board specific microcontroller. The reset and cache subsystems get a few minor updates to SoC specific drivers, while the ff-a, scmi and optee firmware drivers get some code refactoring and new features. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmaVTTUACgkQYKtH/8kJ UiegixAAqGfwUtwk2GGZJlEGjUjT4cqrwCTLhNlaNfgN/dZxjk1XBTKvtp2mVDi2 lJN8TNqa0Csw8XZYPgHi0s1ppmwQl07Unpbc9tUeS4tAeIuputDe+ia0UtQx3Mkd GTAKJO6VzLeCnDxB4757OURZO9wYlPdZycQbnSKDyfBIapFuZwozmbAc7BuFGvBv 2Zt5lca531EJuM5wg25f+F/8XSxZIqjMA6/PTGNCYig1bx5AM2tCWK2xN+BL+dxn YVLuRZT7lSgpwivg9OHzJ49g9WeJB7RArnSDg1Ac7sNfC8476UC17BAH4rF7QSTP q2GBP2VOdRJA9mJkavtLhE/1LPDJuYTM+nt1xq7jzG2MKN7yLjX0LMrMgKsk0pXZ T2qQh7+4MA9lwlpGEwDruMajTJahbMgiAUcSivLsr18LrifAnKVHBDTRmRwNiRX2 T3/zk90kenJX1NOkc4SrdLd5iCyq0oSN+fukdh3UMgJLnAzaWOe5mKAMF7eefeog rMH276W8JwbbmIC4R2aQm6TL7IWBtaCaHuLqYOiTjooir31OgwW4Mztd7okU4v4I rOGhV0zJTSVXT+a4O2jOooWppS9xE45/F2DSigSvZjEiahZ0L4feaOrHui5PVVlW wmFmobCq6Y0Mjspdk64O1tbUWJ17CmRK1WDrUUk0VgmLy9gn6A8= =ChcR -----END PGP SIGNATURE----- Merge tag 'soc-drivers-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull SoC driver updates from Arnd Bergmann: "The updates to the mediatek, allwinner, ti, tegra, microchip, stm32, samsung, imx, zynq and amlogic platoforms are fairly small maintenance changes, either addressing minor mistakes or enabling additional hardware.

- Add support for running the kernel in a SEV-SNP guest, over a Secure
VM Service Module (SVSM).
When running over a SVSM, different services can run at different
protection levels, apart from the guest OS but still within the
secure SNP environment. They can provide services to the guest, like
a vTPM, for example.
This series adds the required facilities to interface with such a SVSM
module.

arm64 updates for 6.11:
* Virtual CPU hotplug support for arm64 ACPI systems
* cpufeature infrastructure cleanups and making the FEAT_ECBHB ID bits
visible to guests
* CPU errata: expand the speculative SSBS workaround to more CPUs
* arm64 ACPI:
- acpi=nospcr option to disable SPCR as default console for arm64
- Move some ACPI code (cpuidle, FFH) to drivers/acpi/arm64/
* GICv3, use compile-time PMR values: optimise the way regular IRQs are
masked/unmasked when GICv3 pseudo-NMIs are used, removing the need for
a static key in fast paths by using a priority value chosen
dynamically at boot time
* arm64 perf updates:
- Rework of the IMX PMU driver to enable support for I.MX95
- Enable support for tertiary match groups in the CMN PMU driver
- Initial refactoring of the CPU PMU code to prepare for the fixed
instruction counter introduced by Arm v9.4
- Add missing PMU driver MODULE_DESCRIPTION() strings
- Hook up DT compatibles for recent CPU PMUs
* arm64 kselftest updates:
- Kernel mode NEON fp-stress
- Cleanups, spelling mistakes
* arm64 Documentation update with a minor clarification on TBI
* Miscellaneous:
- Fix missing IPI statistics
- Implement raw_smp_processor_id() using thread_info rather than a
per-CPU variable (better code generation)
- Make MTE checking of in-kernel asynchronous tag faults conditional
on KASAN being enabled
- Minor cleanups, typos

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 updates from Catalin Marinas:
"The biggest part is the virtual CPU hotplug that touches ACPI,
irqchip. We also have some GICv3 optimisation for pseudo-NMIs that has
been queued via the arm64 tree. Otherwise the usual perf updates,
kselftest, various small cleanups.
Core:
- Virtual CPU hotplug support for arm64 ACPI systems
- cpufeature infrastructure cleanups and making the FEAT_ECBHB ID
bits visible to guests
- CPU errata: expand the speculative SSBS workaround to more CPUs
- GICv3, use compile-time PMR values: optimise the way regular IRQs
are masked/unmasked when GICv3 pseudo-NMIs are used, removing the
need for a static key in fast paths by using a priority value
chosen dynamically at boot time
ACPI:
- 'acpi=nospcr' option to disable SPCR as default console for arm64
- Move some ACPI code (cpuidle, FFH) to drivers/acpi/arm64/
Perf updates:
- Rework of the IMX PMU driver to enable support for I.MX95
- Enable support for tertiary match groups in the CMN PMU driver
- Initial refactoring of the CPU PMU code to prepare for the fixed
instruction counter introduced by Arm v9.4
- Add missing PMU driver MODULE_DESCRIPTION() strings
- Hook up DT compatibles for recent CPU PMUs
Kselftest updates:
- Kernel mode NEON fp-stress
- Cleanups, spelling mistakes
Miscellaneous:
- arm64 Documentation update with a minor clarification on TBI
- Fix missing IPI statistics
- Implement raw_smp_processor_id() using thread_info rather than a
per-CPU variable (better code generation)
- Make MTE checking of in-kernel asynchronous tag faults conditional
on KASAN being enabled
- Minor cleanups, typos"

driver core: auxiliary bus: show auxiliary device IRQs
PCI subfunctions (SF) are anchored on the auxiliary bus. PCI physical and virtual functions are anchored on the PCI bus. The irq information of each such function is visible to users via sysfs directory "msi_irqs" containing files for each irq entry. However, for PCI SFs such information is unavailable. Due to this users have no visibility on IRQs used by the SFs. Secondly, an SF can be multi function device supporting rdma, netdevice and more. Without irq information at the bus level, the user is unable to view or use the affinity of the SF IRQs. Hence to match to the equivalent PCI PFs and VFs, add "irqs" directory, for supporting auxiliary devices, containing file for each irq entry. For example: $ ls /sys/bus/auxiliary/devices/mlx5_core.sf.1/irqs/ 50 51 52 53 54 55 56 57 58 Cc: Simon Horman <horms@kernel.org> Reviewed-by: Przemek Kitszel <przemyslaw.kitszel@intel.com> Reviewed-by: Parav Pandit <parav@nvidia.com> Reviewed-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Shay Drory <shayd@nvidia.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com> --- v9-v10: - remove Przemek RB - add name field to auxiliary_irq_info (Greg and Przemek) - handle bogus IRQ in auxiliary_device_sysfs_irq_remove (Greg) v8-v9: - add Przemek RB - use guard() in auxiliary_irq_dir_prepare (Paolo) v7-v8: - use cleanup.h for info and name fields (Greg) - correct error flow in auxiliary_irq_dir_prepare (Przemek) - add documentation for new fields of auxiliary_device (Simon) v6-v7: - dynamically creating irqs directory when first irq file created (Greg) - removed irqs flag and simplified the dev_add() API (Greg) - move sysfs related new code to a new auxiliary_sysfs.c file (Greg) v5-v6: - removed concept of shared and exclusive and hence global xarray (Greg) v4-v5: - restore global mutex and replace refcount_t with simple integer (Greg) v3->4: - remove global mutex (Przemek) v2->v3: - fix function declaration in case SYSFS isn't defined v1->v2: - move #ifdefs from drivers/base/auxiliary.c to include/linux/auxiliary_bus.h (Greg) - use EXPORT_SYMBOL_GPL instead of EXPORT_SYMBOL (Greg) - Fix kzalloc(ref) to kzalloc(*ref) (Simon) - Add return description in auxiliary_device_sysfs_irq_add() kdoc (Simon) - Fix auxiliary_irq_mode_show doc (kernel test boot) |

cxl/memdev: Replace ENXIO with EBUSY for inject poison limit reached
The CXL driver provides a debugfs interface offering users the ability to inject and clear poison to a memdev. Once a user has injected up to the devices limit further injection requests fail with ENXIO until a clear poison is issued. Users may not have device specs in hand or may want to intentionally hit the limit and then clear. Replace the usual ENXIO return status with EBUSY so users can recognize this failure.

nvmem: core: Implement force_ro sysfs attribute
Implement "force_ro" sysfs attribute to allow users to set read-write devices as read-only and back to read-write from userspace. The choice of the name is based on MMC core 'force_ro' attribute. This solves a situation where an AT24 I2C EEPROM with GPIO based nWP signal may have to be occasionally updated. Such I2C EEPROM device is usually set as read-only during most of the regular system operation, but in case it has to be updated in a controlled manner, it could be unlocked using this new "force_ro" sysfs attribute and then re-locked again. The "read-only" DT property and config->read_only configuration is respected and is used to set default state of the device, read-only or read-write, for devices which do implement .reg_write function. For devices which do not implement .reg_write function, the device is unconditionally read-only and the "force_ro" attribute is not visible.

backlight: Add BACKLIGHT_POWER_ constants for power states
Duplicate FB_BLANK_ constants as BACKLIGHT_POWER__ constants in the backlight header file. Allows backlight drivers to avoid including the fbdev header file and removes a compile-time dependency between the two subsystems. The new BACKLIGHT_POWER_ constants have the same values as their FB_BLANK_ counterparts. Hence UAPI and internal semantics do not change. The backlight drivers can be converted one by one. Each instance of FB_BLANK_UNBLANK becomes BACKLIGHT_POWER_ON, each of FB_BLANK_POWERDOWN becomes BACKLIGHT_POWER_OFF, and FB_BLANK_NORMAL becomes BACKLIGHT_POWER_REDUCED. Backlight code or drivers do not use FB_BLANK_VSYNC_SUSPEND and FB_BLANK_HSYNC_SUSPEND, so no new constants for these are being added. The semantics of FB_BLANK_NORMAL appear inconsistent. In fbdev, NORMAL means display off with sync enabled. In backlight code, this translates to turn the backlight off, but some drivers interpret it as backlight on. So we keep the current code as is, but mark BACKLIGHT_POWER_REDUCED as deprecated. Drivers should be fixed and the constant removed. This affects ams369fg06 and a few DRM panel drivers. v2: - rename BL_CORE_ power constants to BACKLIGHT_POWER_ (Sam) - fix documentation Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Daniel Thompson <daniel.thompson@linaro.org> Link: https://lore.kernel.org/r/20240624152033.25016-2-tzimmermann@suse.de Signed-off-by: Lee Jones <lee@kernel.org> |

misc: keba: Add basic KEBA CP500 system FPGA support
The KEBA CP500 system FPGA is a PCIe device, which consists of multiple IP cores. Every IP core has its own auxiliary driver. The cp500 driver registers an auxiliary device for each device and the corresponding drivers are loaded by the Linux driver infrastructure. Currently 3 variants of this device exists. Every variant has its own PCI device ID, which is used to determine the list of available IP cores. In this first version only the auxiliary device for the I2C controller is registered. Besides the auxiliary device registration some other basic functions of the FPGA are implemented; e.g, FPGA version sysfs file, keep FPGA configuration on reset sysfs file, error message for errors on the internal AXI bus of the FPGA.

xfs: grant heads track byte counts, not LSNs
The grant heads in the log track the space reserved in the log for
running transactions. They do this by tracking how far ahead of the
tail that the reservation has reached, and the units for doing this
are {cycle,bytes} for the reserve head rather than {cycle,blocks}
which are normal used by LSNs.
This is annoyingly complex because we have to split, crack and
combined these tuples for any calculation we do to determine log
space and targets. This is computationally expensive as well as
difficult to do atomically and locklessly, as well as limiting the
size of the log to 2^32 bytes.
Really, though, all the grant heads are tracking is how much space
is currently available for use in the log. We can track this as a
simply byte count - we just don't care what the actual physical
location in the log the head and tail are at, just how much space we
have remaining before the head and tail overlap.
So, convert the grant heads to track the byte reservations that are
active rather than the current (cycle, offset) tuples. This means an
empty log has zero bytes consumed, and a full log is when the
reservations reach the size of the log minus the space consumed by
the AIL.
This greatly simplifies the accounting and checks for whether there
is space available. We no longer need to crack or combine LSNs to
determine how much space the log has left, nor do we need to look at
the head or tail of the log to determine how close to full we are.
There is, however, a complexity that needs to be handled. We know
how much space is being tracked in the AIL now via log->l_tail_space
and the log tickets track active reservations and return the unused
portions to the grant heads when ungranted. Unfortunately, we don't
track the used portion of the grant, so when we transfer log items
from the CIL to the AIL, the space accounted to the grant heads is
transferred to the log tail space. Hence when we move the AIL head
forwards on item insert, we have to remove that space from the grant
heads.
We also remove the xlog_verify_grant_tail() debug function as it is
no longer useful. The check it performs has been racy since delayed
logging was introduced, but now it is clearly only detecting false
positives so remove it.
The result of this substantially simpler accounting algorithm is an
increase in sustained transaction rate from ~1.3 million
transactions/s to ~1.9 million transactions/s with no increase in
CPU usage. We also remove the 32 bit space limitation on the grant
heads, which will allow us to increase the journal size beyond 2GB
in future.
Note that this renames the sysfs files exposing the log grant space
now that the values are exported in bytes. This allows xfstests
to auto-detect the old or new ABI.
[hch: move xlog_grant_sub_space out of line,
update the xlog_grant_{add,sub}_space prototypes,
rename the sysfs files to allow auto-detection in xfstests]

block: Add core atomic write support
Add atomic write support, as follows:
- add helper functions to get request_queue atomic write limits
- report request_queue atomic write support limits to sysfs and update Doc
- support to safely merge atomic writes
- deal with splitting atomic writes
- misc helper functions
- add a per-request atomic write flag
New request_queue limits are added, as follows:
- atomic_write_hw_max is set by the block driver and is the maximum length
of an atomic write which the device may support. It is not
necessarily a power-of-2.
- atomic_write_max_sectors is derived from atomic_write_hw_max_sectors and
max_hw_sectors. It is always a power-of-2. Atomic writes may be merged,
and atomic_write_max_sectors would be the limit on a merged atomic write
request size. This value is not capped at max_sectors, as the value in
max_sectors can be controlled from userspace, and it would only cause
trouble if userspace could limit atomic_write_unit_max_bytes and the
other atomic write limits.
- atomic_write_hw_unit_{min,max} are set by the block driver and are the
min/max length of an atomic write unit which the device may support. They
both must be a power-of-2. Typically atomic_write_hw_unit_max will hold
the same value as atomic_write_hw_max.
- atomic_write_unit_{min,max} are derived from
atomic_write_hw_unit_{min,max}, max_hw_sectors, and block core limits.
Both min and max values must be a power-of-2.
- atomic_write_hw_boundary is set by the block driver. If non-zero, it
indicates an LBA space boundary at which an atomic write straddles no
longer is atomically executed by the disk. The value must be a
power-of-2. Note that it would be acceptable to enforce a rule that
atomic_write_hw_boundary_sectors is a multiple of
atomic_write_hw_unit_max, but the resultant code would be more
complicated.
All atomic writes limits are by default set 0 to indicate no atomic write
support. Even though it is assumed by Linux that a logical block can always
be atomically written, we ignore this as it is not of particular interest.
Stacked devices are just not supported either for now.
An atomic write must always be submitted to the block driver as part of a
single request. As such, only a single BIO must be submitted to the block
layer for an atomic write. When a single atomic write BIO is submitted, it
cannot be split. As such, atomic_write_unit_{max, min}_bytes are limited
by the maximum guaranteed BIO size which will not be required to be split.
This max size is calculated by request_queue max segments and the number
of bvecs a BIO can fit, BIO_MAX_VECS. Currently we rely on userspace
issuing a write with iovcnt=1 for pwritev2() - as such, we can rely on each
segment containing PAGE_SIZE of data, apart from the first+last, which each
can fit logical block size of data. The first+last will be LBS
length/aligned as we rely on direct IO alignment rules also.
New sysfs files are added to report the following atomic write limits:
- atomic_write_unit_max_bytes - same as atomic_write_unit_max_sectors in
bytes
- atomic_write_unit_min_bytes - same as atomic_write_unit_min_sectors in
bytes
- atomic_write_boundary_bytes - same as atomic_write_hw_boundary_sectors in
bytes
- atomic_write_max_bytes - same as atomic_write_max_sectors in bytes
Atomic writes may only be merged with other atomic writes and only under
the following conditions:
- total resultant request length <= atomic_write_max_bytes
- the merged write does not straddle a boundary
Helper function bdev_can_atomic_write() is added to indicate whether
atomic writes may be issued to a bdev. If a bdev is a partition, the
partition start must be aligned with both atomic_write_unit_min_sectors
and atomic_write_hw_boundary_sectors.
FSes will rely on the block layer to validate that an atomic write BIO
submitted will be of valid size, so add blk_validate_atomic_write_op_size()
for this purpose. Userspace expects an atomic write which is of invalid
size to be rejected with -EINVAL, so add BLK_STS_INVAL for this. Also use
BLK_STS_INVAL for when a BIO needs to be split, as this should mean an
invalid size BIO.
Flag REQ_ATOMIC is used for indicating an atomic write.

x86/sev: Extend the config-fs attestation support for an SVSM
When an SVSM is present, the guest can also request attestation reports
from it. These SVSM attestation reports can be used to attest the SVSM
and any services running within the SVSM.
Extend the config-fs attestation support to provide such. This involves
creating four new config-fs attributes:
- 'service-provider' (input)
This attribute is used to determine whether the attestation request
should be sent to the specified service provider or to the SEV
firmware. The SVSM service provider is represented by the value
'svsm'.
- 'service_guid' (input)
Used for requesting the attestation of a single service within the
service provider. A null GUID implies that the SVSM_ATTEST_SERVICES
call should be used to request the attestation report. A non-null
GUID implies that the SVSM_ATTEST_SINGLE_SERVICE call should be used.
- 'service_manifest_version' (input)
Used with the SVSM_ATTEST_SINGLE_SERVICE call, the service version
represents a specific service manifest version be used for the
attestation report.
- 'manifestblob' (output)
Used to return the service manifest associated with the attestation
report.
Only display these new attributes when running under an SVSM.

x86/sev: Provide guest VMPL level to userspace
Requesting an attestation report from userspace involves providing the VMPL level for the report. Currently any value from 0-3 is valid because Linux enforces running at VMPL0. When an SVSM is present, though, Linux will not be running at VMPL0 and only VMPL values starting at the VMPL level Linux is running at to 3 are valid. In order to allow userspace to determine the minimum VMPL value that can be supplied to an attestation report, create a sysfs entry that can be used to retrieve the current VMPL level of the kernel.

perf tools fixes and improvements for v6.10:
- Add Kan Liang to MAINTAINERS as a perf tools reviewer.
- Add support for using the 'capstone' disassembler library in various tools,
such as 'perf script' and 'perf annotate'. This is an alternative for the
use of the 'xed' and 'objdump' disassemblers.
- Data-type profiling improvements:
Resolve types for a->b->c by backtracking the assignments until it finds
DWARF info for one of those members
Support for global variables, keeping a cache to speed up lookups.
Handle the 'call' instruction, dealing with effects on registers and handling
its return when tracking register data types.
Handle x86's segment based addressing like %gs:0x28, to support things like
per CPU variables, the stack canary, etc.
Data-type profiling got big speedups when using capstone for disassembling.
The objdump outoput parsing method is left as a fallback when capstone fails or
isn't available. There are patches posted for 6.11 that to use a LLVM
disassembler.
Support event group display in the TUI when annotating types with --data-type,
for instance to show memory load and store events for the data type fields.
Optimize the 'perf annotate' data structures, reducing memory usage.
Add a initial 'perf test' for 'perf annotate', checking that a target symbol
appears on the output, specifying objdump via the command line, etc.
- Integrate the shellcheck utility with the build of perf to allow catching
shell problems early in areas such as 'perf test', 'perf trace' scrape
scripts, etc.
- Add 'uretprobe' variant in the 'perf bench uprobe' tool.
- Add script to run instances of 'perf script' in parallel.
- Allow parsing tracepoint names that start with digits, such as
9p/9p_client_req, etc. Make sure 'perf test' tests it even on systems
where those tracepoints aren't available.
Vendor Events:
- Update Intel JSON files for Cascade Lake X, Emerald Rapids, Grand Ridge, Ice
Lake X, Lunar Lake, Meteor Lake, Sapphire Rapids, Sierra Forest, Sky Lake X,
Sky Lake and Snow Ridge X. Remove info metrics erroneously in TopdownL1.
- Add AMD's Zen 5 core and uncore events and metrics. Those come from the
"Performance Monitor Counters for AMD Family 1Ah Model 00h- 0Fh Processors"
document, with events that capture information on op dispatch, execution and
retirement, branch prediction, L1 and L2 cache activity, TLB activity, etc.
- Mark L1D_CACHE_INVAL impacted by errata for ARM64's AmpereOne/AmpereOneX.
Miscellaneous:
- Sync header copies with the kernel sources.
- Move some header copies used only for generating translation string tables
for ioctl cmds and other syscall integer arguments to a new directory under
tools/perf/beauty/, to separate from copies in tools/include/ that are used
to build the tools.
- Introduce scrape script for several syscall 'flags'/'mask' arguments.
- Improve cpumap utilization, fixing up pairing of refcounts, using the right
iterators (perf_cpu_map__for_each_cpu), etc.
- Give more details about raw event encodings in 'perf list', show tracepoint
encoding in the detailed output.
- Refactor the DSOs handling code, reducing memory usage.
- Document the BPF event modifier and add a 'perf test' for it.
- Improve the event parser, better error messages and add further 'perf test's
for it.
- Add reference count checking to 'struct comm_str' and 'struct mem_info'.
- Make ARM64's 'perf test' entries for the Neoverse N1 more robust.
- Tweak the ARM64's Coresight 'perf test's.
- Improve ARM64's CoreSight ETM version detection and error reporting.
- Fix handling of symbols when using kcore.
- Fix PAI (Processor Activity Instrumentation) counter names for s390 virtual
machines in 'perf report'.
- Fix -g/--call-graph option failure in 'perf sched timehist'.
- Add LIBTRACEEVENT_DIR build option to allow building with libtraceevent
installed in non-standard directories, such as when doing cross builds.
- Various 'perf test' and 'perf bench' fixes.
- Improve 'perf probe' error message for long C++ probe names.

f2fs update for 6.10-rc1
In this round, we've tried to address some performance issues on zoned storage
such as direct IO and write_hints. In addition, we've migrated some IO paths
using folio. Meanwhile, there are multiple bug fixes in the compression paths,
sanity check conditions, and error handlers.
Enhancement:
- allow direct io of pinned files for zoned storage
- assign the write hint per stream by default
- convert read paths and test_writeback to folio
- avoid allocating WARM_DATA segment for direct IO
Bug fix:
- fix false alarm on invalid block address
- fix to add missing iput() in gc_data_segment()
- fix to release node block count in error path of f2fs_new_node_page()
- compress: don't allow unaligned truncation on released compress inode
- compress: fix to cover {reserve,release}_compress_blocks() w/ cp_rwsem lock
- compress: fix error path of inc_valid_block_count()
- compress: fix to update i_compr_blocks correctly
- fix block migration when section is not aligned to pow2
- don't trigger OPU on pinfile for direct IO
- fix to do sanity check on i_xattr_nid in sanity_check_inode()
- write missing last sum blk of file pinning section
- clear writeback when compression failed
- fix to adjust appropirate defragment pg_end
As usual, there are several minor code clean-ups, and fixes to manage missing
corner cases in the error paths.

powerpc updates for 6.10
- Enable BPF Kernel Functions (kfuncs) in the powerpc BPF JIT.
- Allow per-process DEXCR (Dynamic Execution Control Register) settings via
prctl, notably NPHIE which controls hashst/hashchk for ROP protection.
- Install powerpc selftests in sub-directories. Note this changes the way
run_kselftest.sh needs to be invoked for powerpc selftests.
- Change fadump (Firmware Assisted Dump) to better handle memory add/remove.
- Add support for passing additional parameters to the fadump kernel.
- Add support for updating the kdump image on CPU/memory add/remove events.
- Other small features, cleanups and fixes.

blk-throttle: remove CONFIG_BLK_DEV_THROTTLING_LOW
One the one hand, it's marked EXPERIMENTAL since 2017, and looks like there are no users since then, and no testers and no developers, it's just not active at all. On the other hand, even if the config is disabled, there are still many fields in throtl_grp and throtl_data and many functions that are only used for throtl low. At last, currently blk-throtl is initialized during disk initialization, and destroyed during disk removal, and it exposes many functions to be called directly from block layer. Remove throtl low to make code much more cleaner and follow up work much easier.

leds: trigger: pattern: Add support for hrtimer
Currently, led pattern trigger uses timer_list to schedule brightness changing. As we know from timer_list API [1], it's not accurate to milliseconds and depends on HZ granularity. Example: "0 10 0 0 50 10 50 0 100 10 100 0 150 10 150 0 200 10 200 0 250 10 250 0", we expect it to be 60ms long, but it can actually be up to ~120ms (add ~10ms for each pattern when HZ == 100). But sometimes, userspace needs time accurate led patterns to make sure that pattern will be executed during expected time slot. To achieve this goal the patch introduces optional hrtimer usage for led trigger pattern, because hrtimer is microseconds accurate timer.

powerpc/fadump: add hotplug_ready sysfs interface
The elfcorehdr describes the CPUs and memory of the crashed kernel to
the kernel that captures the dump, known as the second or fadump kernel.
The elfcorehdr needs to be updated if the system's memory changes due to
memory hotplug or online/offline events.
Currently, memory hotplug events are monitored in userspace by udev
rules, and fadump is re-registered, which recreates the elfcorehdr with
the latest available memory in the system.
However, the previous patch ("powerpc: make fadump resilient with memory
add/remove events") moved the creation of elfcorehdr to the second or
fadump kernel. This eliminates the need to regenerate the elfcorehdr
during memory hotplug or online/offline events.
Create a sysfs entry at /sys/kernel/fadump/hotplug_ready to let
userspace know that fadump re-registration is not required for memory
add/remove events.

platform/x86: wmi: Add MSI WMI Platform driver
Add a new driver for the MSI WMI Platform interface. The underlying ACPI WMI interface supports many features, but so far only reading of fan speed sensors is implemented. The driver was reverse-engineered based on a user request to the lm-sensors project, see the github issue for details. The ACPI WMI interface used by this driver seems to use the same embedded controller interface as the msi-ec driver, but supports automatic discovery of supported machines without relying on a DMI whitelist. The driver was tested by the user who created the github issue.

drm/xe/hwmon: Add infra to support card power and energy attributes
Add infra to support card power and energy attributes through channel 0.
Package attributes will be now exposed through channel 1 rather than
channel 0 as shown below.
Channel 0 i.e power1/energy1_xxx used for card and
channel 1 i.e power2/energy2_xxx used for package power,energy attributes.
power1/curr1_crit and in0_input are moved to channel 1, i.e.
power2/curr2_crit and in1_input as these are available for package only.
This would be needed for future platforms where they might be
separate registers for package and card power and energy.
Each discrete GPU supported by Xe driver, would have a directory in
/sys/class/hwmon/ with multiple channels under it.
Each channel would have attributes for power, energy etc.
Ex: /sys/class/hwmon/hwmon2/power1_max
/power1_label
/energy1_input
/energy1_label
Attributes will have a label to get more description of it.
Labelling is as below.
power1_label/energy1_label - "card",
power2_label/energy2_label - "pkg".
v2: Fix checkpatch errors.
v3:
- Update intel-xe-hwmon documentation. (Riana, Badal)
- Rename hwmon card channel enum from CHANNEL_PLATFORM
to CHANNEL_CARD. (Riana)
v4:
- Remove unrelated changes from patch. (Anshuman)
- Fix typo in commit msg.
v5:
- Update commit message and intel-xe-hwmon documentation with "Xe"
instead of xe when using it as a name. (Rodrigo)

usb: misc: onboard_hub: rename to onboard_dev
This patch prepares onboad_hub to support non-hub devices by renaming the driver files and their content, the headers and their references. The comments and descriptions have been slightly modified to keep coherence and account for the specific cases that only affect onboard hubs (e.g. peer-hub). The "hub" variables in functions where "dev" (and similar names) variables already exist have been renamed to onboard_dev for clarity, which adds a few lines in cases where more than 80 characters are used. No new functionality has been added.

- IIO driver updates, loads of new ones and evolution of existing ones
- coresight driver updates
- const cleanups for many driver subsystems
- speakup driver additions
- platform remove callback void cleanups
- mei driver updates
- mhi driver updates
- cdx driver updates for MSI interrupt handling
- nvmem driver updates
- other smaller driver updates and cleanups, full details in the
shortlog
All of these have been in linux-next for a long time with no reported

f2fs update for 6.9-rc1
In this round, there are a number of updates on mainly two areas: Zoned block
device support and Per-file compression. For example, we've found several issues
to support Zoned block device especially having large sections regarding to GC
and file pinning used for Android devices. In compression side, we've fixed many
corner race conditions that had broken the design assumption.
Enhancement:
- Support file pinning for Zoned block device having large section
- Enhance the data recovery after sudden power cut on Zoned block device
- Add more error injection cases to easily detect the kernel panics
- add a proc entry show the entire disk layout
- Improve various error paths paniced by BUG_ON in block allocation and GC
- support SEEK_DATA and SEEK_HOLE for compression files
Bug fix:
- fix to avoid use-after-free issue in f2fs_filemap_fault
- fix some race conditions to break the atomic write design assumption
- fix to truncate meta inode pages forcely
- resolve various per-file compression issues wrt the space management and
compression policies
- fix some swap-related bugs
In addition, we removed deprecated codes such as io_bits and heap_allocation,
and also fixed minor error handling routines with neat debugging messages.

Merge tag 'cxl-for-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl
Pull CXL updates from Dan Williams:
"CXL has mechanisms to enumerate the performance characteristics of
memory devices. Those mechanisms allow Linux to build the equivalent
of ACPI SRAT, SLIT, and HMAT tables dynamically at runtime. That
capability is necessary because static ACPI can not represent dynamic
CXL configurations (and reconfigurations).
So, building on the v6.8 work to add "Quality of Service" enumeration,
this update plumbs CXL "access coordinates" (read/write access latency
and bandwidth) in all the same places that ACPI HMAT feeds similar
data. Follow-on patches from the -mm side can then use that data to
feed mechanisms like mm/memory-tiers.c. Greg has acked the touch to
drivers/base/.
The other feature update this cycle is support for CXL error injection
via the ACPI EINJ module. That facility enables injection of bus
protocol errors provided the user knows the magic address values to
insert in the interface. To hide that magic, and make this easier to
use, new error injection attributes were added to CXL debugfs. That
interface injects the errors relative to a CXL object rather than
require user tooling to know how to lookup and inject RCRB (Root
Complex Register Block) addresses into the raw EINJ debugfs interface.
It received some helpful review comments from Tony, but no explicit
acks from the ACPI side. The primary user visible change for existing
EINJ users is that they may find that einj.ko was already loaded by
cxl_core.ko. Previously, einj.ko was only loaded on demand.
The usual collection of miscellaneous cleanups are also present this
cycle.
Summary:
- Supplement ACPI HMAT reported memory performance with native CXL
memory performance enumeration
- Add support for CXL error injection via the ACPI EINJ mechanism
- Cleanup CXL DOE and CDAT integration
- Miscellaneous cleanups and fixes"

- Sumanth Korikkar has taught s390 to allocate hotplug-time page frames
from hotplugged memory rather than only from main memory. Series
"implement "memmap on memory" feature on s390".
- More folio conversions from Matthew Wilcox in the series
"Convert memcontrol charge moving to use folios"
"mm: convert mm counter to take a folio"
- Chengming Zhou has optimized zswap's rbtree locking, providing
significant reductions in system time and modest but measurable
reductions in overall runtimes. The series is "mm/zswap: optimize the
scalability of zswap rb-tree".
- Chengming Zhou has also provided the series "mm/zswap: optimize zswap
lru list" which provides measurable runtime benefits in some
swap-intensive situations.
- And Chengming Zhou further optimizes zswap in the series "mm/zswap:
optimize for dynamic zswap_pools". Measured improvements are modest.
- zswap cleanups and simplifications from Yosry Ahmed in the series "mm:
zswap: simplify zswap_swapoff()".
- In the series "Add DAX ABI for memmap_on_memory", Vishal Verma has
contributed several DAX cleanups as well as adding a sysfs tunable to
control the memmap_on_memory setting when the dax device is hotplugged
as system memory.
- Johannes Weiner has added the large series "mm: zswap: cleanups",
which does that.
- More DAMON work from SeongJae Park in the series
"mm/damon: make DAMON debugfs interface deprecation unignorable"
"selftests/damon: add more tests for core functionalities and corner cases"
"Docs/mm/damon: misc readability improvements"
"mm/damon: let DAMOS feeds and tame/auto-tune itself"
- In the series "mm/mempolicy: weighted interleave mempolicy and sysfs
extension" Rakie Kim has developed a new mempolicy interleaving policy
wherein we allocate memory across nodes in a weighted fashion rather
than uniformly. This is beneficial in heterogeneous memory environments
appearing with CXL.
- Christophe Leroy has contributed some cleanup and consolidation work
against the ARM pagetable dumping code in the series "mm: ptdump:
Refactor CONFIG_DEBUG_WX and check_wx_pages debugfs attribute".
- Luis Chamberlain has added some additional xarray selftesting in the
series "test_xarray: advanced API multi-index tests".
- Muhammad Usama Anjum has reworked the selftest code to make its
human-readable output conform to the TAP ("Test Anything Protocol")
format. Amongst other things, this opens up the use of third-party
tools to parse and process out selftesting results.
- Ryan Roberts has added fork()-time PTE batching of THP ptes in the
series "mm/memory: optimize fork() with PTE-mapped THP". Mainly
targeted at arm64, this significantly speeds up fork() when the process
has a large number of pte-mapped folios.
- David Hildenbrand also gets in on the THP pte batching game in his
series "mm/memory: optimize unmap/zap with PTE-mapped THP". It
implements batching during munmap() and other pte teardown situations.
The microbenchmark improvements are nice.
- And in the series "Transparent Contiguous PTEs for User Mappings" Ryan
Roberts further utilizes arm's pte's contiguous bit ("contpte
mappings"). Kernel build times on arm64 improved nicely. Ryan's series
"Address some contpte nits" provides some followup work.
- In the series "mm/hugetlb: Restore the reservation" Breno Leitao has
fixed an obscure hugetlb race which was causing unnecessary page faults.
He has also added a reproducer under the selftest code.
- In the series "selftests/mm: Output cleanups for the compaction test",
Mark Brown did what the title claims.
- Kinsey Ho has added the series "mm/mglru: code cleanup and refactoring".
- Even more zswap material from Nhat Pham. The series "fix and extend
zswap kselftests" does as claimed.
- In the series "Introduce cpu_dcache_is_aliasing() to fix DAX
regression" Mathieu Desnoyers has cleaned up and fixed rather a mess in
our handling of DAX on archiecctures which have virtually aliasing data
caches. The arm architecture is the main beneficiary.
- Lokesh Gidra's series "per-vma locks in userfaultfd" provides dramatic
improvements in worst-case mmap_lock hold times during certain
userfaultfd operations.
- Some page_owner enhancements and maintenance work from Oscar Salvador
in his series
"page_owner: print stacks and their outstanding allocations"
"page_owner: Fixup and cleanup"
- Uladzislau Rezki has contributed some vmalloc scalability improvements
in his series "Mitigate a vmap lock contention". It realizes a 12x
improvement for a certain microbenchmark.
- Some kexec/crash cleanup work from Baoquan He in the series "Split
crash out from kexec and clean up related config items".
- Some zsmalloc maintenance work from Chengming Zhou in the series
"mm/zsmalloc: fix and optimize objects/page migration"
"mm/zsmalloc: some cleanup for get/set_zspage_mapping()"
- Zi Yan has taught the MM to perform compaction on folios larger than
order=0. This a step along the path to implementaton of the merging of
large anonymous folios. The series is named "Enable >0 order folio
memory compaction".
- Christoph Hellwig has done quite a lot of cleanup work in the
pagecache writeback code in his series "convert write_cache_pages() to
an iterator".
- Some modest hugetlb cleanups and speedups in Vishal Moola's series
"Handle hugetlb faults under the VMA lock".
- Zi Yan has changed the page splitting code so we can split huge pages
into sizes other than order-0 to better utilize large folios. The
series is named "Split a folio to any lower order folios".
- David Hildenbrand has contributed the series "mm: remove
total_mapcount()", a cleanup.
- Matthew Wilcox has sought to improve the performance of bulk memory
freeing in his series "Rearrange batched folio freeing".
- Gang Li's series "hugetlb: parallelize hugetlb page init on boot"
provides large improvements in bootup times on large machines which are
configured to use large numbers of hugetlb pages.
- Matthew Wilcox's series "PageFlags cleanups" does that.
- Qi Zheng's series "minor fixes and supplement for ptdesc" does that
also. S390 is affected.
- Cleanups to our pagemap utility functions from Peter Xu in his series
"mm/treewide: Replace pXd_large() with pXd_leaf()".
- Nico Pache has fixed a few things with our hugepage selftests in his
series "selftests/mm: Improve Hugepage Test Handling in MM Selftests".
- Also, of course, many singleton patches to many things. Please see
the individual changelogs for details.

- Sumanth Korikkar has taught s390 to allocate hotplug-time page frames
from hotplugged memory rather than only from main memory. Series
"implement "memmap on memory" feature on s390".
- More folio conversions from Matthew Wilcox in the series
"Convert memcontrol charge moving to use folios"
"mm: convert mm counter to take a folio"
- Chengming Zhou has optimized zswap's rbtree locking, providing
significant reductions in system time and modest but measurable
reductions in overall runtimes. The series is "mm/zswap: optimize the
scalability of zswap rb-tree".
- Chengming Zhou has also provided the series "mm/zswap: optimize zswap
lru list" which provides measurable runtime benefits in some
swap-intensive situations.
- And Chengming Zhou further optimizes zswap in the series "mm/zswap:
optimize for dynamic zswap_pools". Measured improvements are modest.
- zswap cleanups and simplifications from Yosry Ahmed in the series
"mm: zswap: simplify zswap_swapoff()".
- In the series "Add DAX ABI for memmap_on_memory", Vishal Verma has
contributed several DAX cleanups as well as adding a sysfs tunable to
control the memmap_on_memory setting when the dax device is
hotplugged as system memory.
- Johannes Weiner has added the large series "mm: zswap: cleanups",
which does that.
- More DAMON work from SeongJae Park in the series
"mm/damon: make DAMON debugfs interface deprecation unignorable"
"selftests/damon: add more tests for core functionalities and corner cases"
"Docs/mm/damon: misc readability improvements"
"mm/damon: let DAMOS feeds and tame/auto-tune itself"
- In the series "mm/mempolicy: weighted interleave mempolicy and sysfs
extension" Rakie Kim has developed a new mempolicy interleaving
policy wherein we allocate memory across nodes in a weighted fashion
rather than uniformly. This is beneficial in heterogeneous memory
environments appearing with CXL.
- Christophe Leroy has contributed some cleanup and consolidation work
against the ARM pagetable dumping code in the series "mm: ptdump:
Refactor CONFIG_DEBUG_WX and check_wx_pages debugfs attribute".
- Luis Chamberlain has added some additional xarray selftesting in the
series "test_xarray: advanced API multi-index tests".
- Muhammad Usama Anjum has reworked the selftest code to make its
human-readable output conform to the TAP ("Test Anything Protocol")
format. Amongst other things, this opens up the use of third-party
tools to parse and process out selftesting results.
- Ryan Roberts has added fork()-time PTE batching of THP ptes in the
series "mm/memory: optimize fork() with PTE-mapped THP". Mainly
targeted at arm64, this significantly speeds up fork() when the
process has a large number of pte-mapped folios.
- David Hildenbrand also gets in on the THP pte batching game in his
series "mm/memory: optimize unmap/zap with PTE-mapped THP". It
implements batching during munmap() and other pte teardown
situations. The microbenchmark improvements are nice.
- And in the series "Transparent Contiguous PTEs for User Mappings"
Ryan Roberts further utilizes arm's pte's contiguous bit ("contpte
mappings"). Kernel build times on arm64 improved nicely. Ryan's
series "Address some contpte nits" provides some followup work.
- In the series "mm/hugetlb: Restore the reservation" Breno Leitao has
fixed an obscure hugetlb race which was causing unnecessary page
faults. He has also added a reproducer under the selftest code.
- In the series "selftests/mm: Output cleanups for the compaction
test", Mark Brown did what the title claims.
- Kinsey Ho has added the series "mm/mglru: code cleanup and
refactoring".
- Even more zswap material from Nhat Pham. The series "fix and extend
zswap kselftests" does as claimed.
- In the series "Introduce cpu_dcache_is_aliasing() to fix DAX
regression" Mathieu Desnoyers has cleaned up and fixed rather a mess
in our handling of DAX on archiecctures which have virtually aliasing
data caches. The arm architecture is the main beneficiary.
- Lokesh Gidra's series "per-vma locks in userfaultfd" provides
dramatic improvements in worst-case mmap_lock hold times during
certain userfaultfd operations.
- Some page_owner enhancements and maintenance work from Oscar Salvador
in his series
"page_owner: print stacks and their outstanding allocations"
"page_owner: Fixup and cleanup"
- Uladzislau Rezki has contributed some vmalloc scalability
improvements in his series "Mitigate a vmap lock contention". It
realizes a 12x improvement for a certain microbenchmark.
- Some kexec/crash cleanup work from Baoquan He in the series "Split
crash out from kexec and clean up related config items".
- Some zsmalloc maintenance work from Chengming Zhou in the series
"mm/zsmalloc: fix and optimize objects/page migration"
"mm/zsmalloc: some cleanup for get/set_zspage_mapping()"
- Zi Yan has taught the MM to perform compaction on folios larger than
order=0. This a step along the path to implementaton of the merging
of large anonymous folios. The series is named "Enable >0 order folio
memory compaction".
- Christoph Hellwig has done quite a lot of cleanup work in the
pagecache writeback code in his series "convert write_cache_pages()
to an iterator".
- Some modest hugetlb cleanups and speedups in Vishal Moola's series
"Handle hugetlb faults under the VMA lock".
- Zi Yan has changed the page splitting code so we can split huge pages
into sizes other than order-0 to better utilize large folios. The
series is named "Split a folio to any lower order folios".
- David Hildenbrand has contributed the series "mm: remove
total_mapcount()", a cleanup.
- Matthew Wilcox has sought to improve the performance of bulk memory
freeing in his series "Rearrange batched folio freeing".
- Gang Li's series "hugetlb: parallelize hugetlb page init on boot"
provides large improvements in bootup times on large machines which
are configured to use large numbers of hugetlb pages.
- Matthew Wilcox's series "PageFlags cleanups" does that.
- Qi Zheng's series "minor fixes and supplement for ptdesc" does that
also. S390 is affected.
- Cleanups to our pagemap utility functions from Peter Xu in his series
"mm/treewide: Replace pXd_large() with pXd_leaf()".
- Nico Pache has fixed a few things with our hugepage selftests in his
series "selftests/mm: Improve Hugepage Test Handling in MM
Selftests".
- Also, of course, many singleton patches to many things. Please see
the individual changelogs for details.

Documentation/ABI/testing/debugfs-cxl: Fix "Unexpected indentation"
Stephen reported that an htmldocs build hit:
Documentation/ABI/testing/debugfs-cxl:38: ERROR: Unexpected indentation.
It turns out that line was fine but the tool was unhappy about some line
breaks in the table of values to error types.
It turns out that:
make V=1 SPHINXDIRS="admin-guide" htmldocs
...can not be used to get more info about what is behind a documentation
build error. It was only pure luck that reflowing the text resulted in
an error message that seemed a imply a problem later on with line breaks
around the table.
Fixes:

Pull PCI updates from Bjorn Helgaas:
"Enumeration:
- Consolidate interrupt related code in irq.c (Ilpo Järvinen)
- Reduce kernel size by replacing sysfs resource macros with
functions (Ilpo Järvinen)
- Reduce kernel size by compiling sysfs support only when
CONFIG_SYSFS=y (Lukas Wunner)
- Avoid using Extended Tags on 3ware-9650SE Root Port to work around
an apparent hardware defect (Jörg Wedekind)
Resource management:
- Fix an MMIO mapping leak in pci_iounmap() (Philipp Stanner)
- Move pci_iomap.c and other PCI-specific devres code to drivers/pci
(Philipp Stanner)
- Consolidate PCI devres code in devres.c (Philipp Stanner)
Power management:
- Avoid D3cold on Asus B1400 PCI-NVMe bridge, where firmware doesn't
know how to return correctly to D0, and remove previous quirk that
wasn't as specific (Daniel Drake)
- Allow runtime PM when the driver enables it but doesn't need any
runtime PM callbacks (Raag Jadav)
- Drain runtime-idle callbacks before driver removal to avoid races
between .remove() and .runtime_idle(), which caused intermittent
page faults when the rtsx .runtime_idle() accessed registers that
its .remove() had already unmapped (Rafael J. Wysocki)
Virtualization:
- Avoid Secondary Bus Reset on LSI FW643 so it can be assigned to VMs
with VFIO, e.g., for professional audio software on many Apple
machines, at the cost of leaking state between VMs (Edmund Raile)
Error handling:
- Print all logged TLP Prefixes, not just the first, after AER or DPC
errors (Ilpo Järvinen)
- Quirk the DPC PIO log size for Intel Raptor Lake Root Ports, which
still don't advertise a legal size (Paul Menzel)
- Ignore expected DPC Surprise Down errors on hot removal (Smita
Koralahalli)
- Block runtime suspend while handling AER errors to avoid races that
prevent the device form being resumed from D3hot (Stanislaw
Gruszka)
Peer-to-peer DMA:
- Use atomic XA allocation in RCU read section (Christophe JAILLET)
ASPM:
- Collect bits of ASPM-related code that we need even without
CONFIG_PCIEASPM into aspm.c (David E. Box)
- Save/restore L1 PM Substates config for suspend/resume (David E.
Box)
- Update save_save when ASPM config is changed, so a .slot_reset()
during error recovery restores the changed config, not the
.probe()-time config (Vidya Sagar)
Endpoint framework:
- Refactor and improve pci_epf_alloc_space() API (Niklas Cassel)
- Clean up endpoint BAR descriptions (Niklas Cassel)
- Fix ntb_register_device() name leak in error path (Yang Yingliang)
- Return actual error code for pci_vntb_probe() failure (Yang
Yingliang)
Broadcom STB PCIe controller driver:
- Fix MDIO write polling, which previously never waited for
completion (Jonathan Bell)
Cadence PCIe endpoint driver:
- Clear the ARI "Next Function Number" of last function (Jasko-EXT
Wojciech)
Freescale i.MX6 PCIe controller driver:
- Simplify by replacing switch statements with function pointers for
different hardware variants (Frank Li)
- Simplify by using clk_bulk*() API (Frank Li)
- Remove redundant DT clock and reg/reg-name details (Frank Li)
- Add i.MX95 DT and driver support for both Root Complex and Endpoint
mode (Frank Li)
Microsoft Hyper-V host bridge driver:
- Reduce memory usage by limiting ring buffer size to 16KB instead of
4 pages (Michael Kelley)
Qualcomm PCIe controller driver:
- Add X1E80100 DT and driver support (Abel Vesa)
- Add DT 'required-opps' for SoCs that require a minimum performance
level (Johan Hovold)
- Make DT 'msi-map-mask' optional, depending on how MSI interrupts
are mapped (Johan Hovold)
- Disable ASPM L0s for sc8280xp, sa8540p and sa8295p because the PHY
configuration isn't tuned correctly for L0s (Johan Hovold)
- Split dt-binding qcom,pcie.yaml into qcom,pcie-common.yaml and
separate files for SA8775p, SC7280, SC8180X, SC8280XP, SM8150,
SM8250, SM8350, SM8450, SM8550 for easier reviewing (Krzysztof
Kozlowski)
- Enable BDF to SID translation by disabling bypass mode (Manivannan
Sadhasivam)
- Add endpoint MHI support for Snapdragon SA8775P SoC (Mrinmay
Sarkar)
Synopsys DesignWare PCIe controller driver:
- Allocate 64-bit MSI address if no 32-bit address is available (Ajay
Agarwal)
- Fix endpoint Resizable BAR to actually advertise the required 1MB
size (Niklas Cassel)
MicroSemi Switchtec management driver:
- Release resources if the .probe() fails (Christophe JAILLET)

gpio updates for v6.9
Serialization rework:
- use SRCU to serialize access to the global GPIO device list, to GPIO device
structs themselves and to GPIO descriptors
- make the GPIO subsystem resilient to the GPIO providers being unbound while
the API calls are in progress
- don't dereference the SRCU-protected chip pointer if the information we need
can be obtained from the GPIO device structure
- move some of the information contained in struct gpio_chip to struct
gpio_device to further reduce the need to dereference the former
- pass the GPIO device struct instead of the GPIO chip to sysfs callback to,
again, reduce the need for accessing the latter
- get GPIO descriptors from the GPIO device, not from the chip for the same
reason
- allow for mostly lockless operation of the GPIO driver API: assure
consistency with SRCU and atomic operations
- remove the global GPIO spinlock

- don't warn about removing GPIO chips with descriptors still held by users as
we can now handle this situation gracefully
- remove unused logging helpers
- unexport functions that are only used internally in the GPIO subsystem
- set the device type (assign the relevant struct device_type) for GPIO devices
New drivers:
- add the ChromeOS EC GPIO driver
Driver improvements:
- allow building gpio-vf610 with COMPILE_TEST as well as disabling it in
menuconfig (before it was always built for i.MX cofigs)
- count the number of EICs using the device properties instead of hard-coding
it in gpio-eic-sprd

Pull gpio updates from Bartosz Golaszewski:
"The biggest feature is the locking overhaul. Up until now the
synchronization in the GPIO subsystem was broken. There was a single
spinlock "protecting" multiple data structures but doing it wrong (as
evidenced by several places where it would be released when a sleeping
function was called and then reacquired without checking the protected
state).
We tried to use an RW semaphore before but the main issue with GPIO is
that we have drivers implementing the interfaces in both sleeping and
non-sleeping ways as well as user-facing interfaces that can be called
both from process as well as atomic contexts. Both ends converge in
the same code paths that can use neither spinlocks nor mutexes. The
only reasonable way out is to use SRCU and go mostly lockless. To that
end: we add several SRCU structs in relevant places and use them to
assure consistency between API calls together with atomic reads and
writes of GPIO descriptor flags where it makes sense.
This code has spent several weeks in next and has received several
fixes in the first week or two after which it stabilized nicely. The
GPIO subsystem is now resilient to providers being suddenly unbound.
We managed to also remove the existing character device RW semaphore
and the obsolete global spinlock.
Other than the locking rework we have one new driver (for Chromebook
EC), much appreciated documentation improvements from Kent and the
regular driver improvements, DT-bindings updates and GPIOLIB core
tweaks.

cxl/core: Add CXL EINJ debugfs files
Export CXL helper functions in einj-cxl.c for getting/injecting available CXL protocol error types to sysfs under kernel/debug/cxl. The kernel/debug/cxl/einj_types file will print the available CXL protocol errors in the same format as the available_error_types file provided by the einj module. The kernel/debug/cxl/$dport_dev/einj_inject file is functionally the same as the error_type and error_inject files provided by the EINJ module, i.e.: writing an error type into $dport_dev/einj_inject will inject said error type into the CXL dport represented by $dport_dev.

Networking changes for 6.9.
Core & protocols
----------------
- Large effort by Eric to lower rtnl_lock pressure and remove locks:
- Make commonly used parts of rtnetlink (address, route dumps etc.)
lockless, protected by RCU instead of rtnl_lock.
- Add a netns exit callback which already holds rtnl_lock,
allowing netns exit to take rtnl_lock once in the core
instead of once for each driver / callback.
- Remove locks / serialization in the socket diag interface.
- Remove 6 calls to synchronize_rcu() while holding rtnl_lock.
- Remove the dev_base_lock, depend on RCU where necessary.
- Support busy polling on a per-epoll context basis. Poll length
and budget parameters can be set independently of system defaults.
- Introduce struct net_hotdata, to make sure read-mostly global config
variables fit in as few cache lines as possible.
- Add optional per-nexthop statistics to ease monitoring / debug
of ECMP imbalance problems.
- Support TCP_NOTSENT_LOWAT in MPTCP.
- Ensure that IPv6 temporary addresses' preferred lifetimes are long
enough, compared to other configured lifetimes, and at least 2 sec.
- Support forwarding of ICMP Error messages in IPSec, per RFC 4301.
- Add support for the independent control state machine for bonding
per IEEE 802.1AX-2008 5.4.15 in addition to the existing coupled
control state machine.
- Add "network ID" to MCTP socket APIs to support hosts with multiple
disjoint MCTP networks.
- Re-use the mono_delivery_time skbuff bit for packets which user
space wants to be sent at a specified time. Maintain the timing
information while traversing veth links, bridge etc.
- Take advantage of MSG_SPLICE_PAGES for RxRPC DATA and ACK packets.
- Simplify many places iterating over netdevs by using an xarray
instead of a hash table walk (hash table remains in place, for
use on fastpaths).
- Speed up scanning for expired routes by keeping a dedicated list.
- Speed up "generic" XDP by trying harder to avoid large allocations.
- Support attaching arbitrary metadata to netconsole messages.
Things we sprinkled into general kernel code
--------------------------------------------
- Enforce VM_IOREMAP flag and range in ioremap_page_range and introduce
VM_SPARSE kind and vm_area_[un]map_pages (used by bpf_arena).
- Rework selftest harness to enable the use of the full range of
ksft exit code (pass, fail, skip, xfail, xpass).
Netfilter
---------
- Allow userspace to define a table that is exclusively owned by a daemon
(via netlink socket aliveness) without auto-removing this table when
the userspace program exits. Such table gets marked as orphaned and
a restarting management daemon can re-attach/regain ownership.
- Speed up element insertions to nftables' concatenated-ranges set type.
Compact a few related data structures.
BPF
---
- Add BPF token support for delegating a subset of BPF subsystem
functionality from privileged system-wide daemons such as systemd
through special mount options for userns-bound BPF fs to a trusted
& unprivileged application.
- Introduce bpf_arena which is sparse shared memory region between BPF
program and user space where structures inside the arena can have
pointers to other areas of the arena, and pointers work seamlessly
for both user-space programs and BPF programs.
- Introduce may_goto instruction that is a contract between the verifier
and the program. The verifier allows the program to loop assuming it's
behaving well, but reserves the right to terminate it.
- Extend the BPF verifier to enable static subprog calls in spin lock
critical sections.
- Support registration of struct_ops types from modules which helps
projects like fuse-bpf that seeks to implement a new struct_ops type.
- Add support for retrieval of cookies for perf/kprobe multi links.
- Support arbitrary TCP SYN cookie generation / validation in the TC
layer with BPF to allow creating SYN flood handling in BPF firewalls.
- Add code generation to inline the bpf_kptr_xchg() helper which
improves performance when stashing/popping the allocated BPF objects.
Wireless
--------
- Add SPP (signaling and payload protected) AMSDU support.
- Support wider bandwidth OFDMA, as required for EHT operation.
Driver API
----------
- Major overhaul of the Energy Efficient Ethernet internals to support
new link modes (2.5GE, 5GE), share more code between drivers
(especially those using phylib), and encourage more uniform behavior.
Convert and clean up drivers.
- Define an API for querying per netdev queue statistics from drivers.
- IPSec: account in global stats for fully offloaded sessions.
- Create a concept of Ethernet PHY Packages at the Device Tree level,
to allow parameterizing the existing PHY package code.
- Enable Rx hashing (RSS) on GTP protocol fields.
Misc
----
- Improvements and refactoring all over networking selftests.
- Create uniform module aliases for TC classifiers, actions,
and packet schedulers to simplify creating modprobe policies.
- Address all missing MODULE_DESCRIPTION() warnings in networking.
- Extend the Netlink descriptions in YAML to cover message encapsulation
or "Netlink polymorphism", where interpretation of nested attributes
depends on link type, classifier type or some other "class type".
Drivers
-------
- Ethernet high-speed NICs:
- Add a new driver for Marvell's Octeon PCI Endpoint NIC VF.

Merge tag 'net-next-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Jakub Kicinski:
"Core & protocols:
- Large effort by Eric to lower rtnl_lock pressure and remove locks:
- Make commonly used parts of rtnetlink (address, route dumps
etc) lockless, protected by RCU instead of rtnl_lock.
- Add a netns exit callback which already holds rtnl_lock,
allowing netns exit to take rtnl_lock once in the core instead
of once for each driver / callback.
- Remove locks / serialization in the socket diag interface.
- Remove 6 calls to synchronize_rcu() while holding rtnl_lock.
- Remove the dev_base_lock, depend on RCU where necessary.
- Support busy polling on a per-epoll context basis. Poll length and
budget parameters can be set independently of system defaults.
- Introduce struct net_hotdata, to make sure read-mostly global
config variables fit in as few cache lines as possible.
- Add optional per-nexthop statistics to ease monitoring / debug of
ECMP imbalance problems.
- Support TCP_NOTSENT_LOWAT in MPTCP.
- Ensure that IPv6 temporary addresses' preferred lifetimes are long
enough, compared to other configured lifetimes, and at least 2 sec.
- Support forwarding of ICMP Error messages in IPSec, per RFC 4301.
- Add support for the independent control state machine for bonding
per IEEE 802.1AX-2008 5.4.15 in addition to the existing coupled
control state machine.
- Add "network ID" to MCTP socket APIs to support hosts with multiple
disjoint MCTP networks.
- Re-use the mono_delivery_time skbuff bit for packets which user
space wants to be sent at a specified time. Maintain the timing
information while traversing veth links, bridge etc.
- Take advantage of MSG_SPLICE_PAGES for RxRPC DATA and ACK packets.
- Simplify many places iterating over netdevs by using an xarray
instead of a hash table walk (hash table remains in place, for use
on fastpaths).
- Speed up scanning for expired routes by keeping a dedicated list.
- Speed up "generic" XDP by trying harder to avoid large allocations.
- Support attaching arbitrary metadata to netconsole messages.
Things we sprinkled into general kernel code:
- Enforce VM_IOREMAP flag and range in ioremap_page_range and
introduce VM_SPARSE kind and vm_area_[un]map_pages (used by
bpf_arena).
- Rework selftest harness to enable the use of the full range of ksft
exit code (pass, fail, skip, xfail, xpass).
Netfilter:
- Allow userspace to define a table that is exclusively owned by a
daemon (via netlink socket aliveness) without auto-removing this
table when the userspace program exits. Such table gets marked as
orphaned and a restarting management daemon can re-attach/regain
ownership.
- Speed up element insertions to nftables' concatenated-ranges set
type. Compact a few related data structures.
BPF:
- Add BPF token support for delegating a subset of BPF subsystem
functionality from privileged system-wide daemons such as systemd
through special mount options for userns-bound BPF fs to a trusted
& unprivileged application.
- Introduce bpf_arena which is sparse shared memory region between
BPF program and user space where structures inside the arena can
have pointers to other areas of the arena, and pointers work
seamlessly for both user-space programs and BPF programs.
- Introduce may_goto instruction that is a contract between the
verifier and the program. The verifier allows the program to loop
assuming it's behaving well, but reserves the right to terminate
it.
- Extend the BPF verifier to enable static subprog calls in spin lock
critical sections.
- Support registration of struct_ops types from modules which helps
projects like fuse-bpf that seeks to implement a new struct_ops
type.
- Add support for retrieval of cookies for perf/kprobe multi links.
- Support arbitrary TCP SYN cookie generation / validation in the TC
layer with BPF to allow creating SYN flood handling in BPF
firewalls.
- Add code generation to inline the bpf_kptr_xchg() helper which
improves performance when stashing/popping the allocated BPF
objects.
Wireless:
- Add SPP (signaling and payload protected) AMSDU support.
- Support wider bandwidth OFDMA, as required for EHT operation.
Driver API:
- Major overhaul of the Energy Efficient Ethernet internals to
support new link modes (2.5GE, 5GE), share more code between
drivers (especially those using phylib), and encourage more
uniform behavior. Convert and clean up drivers.
- Define an API for querying per netdev queue statistics from
drivers.
- IPSec: account in global stats for fully offloaded sessions.
- Create a concept of Ethernet PHY Packages at the Device Tree level,
to allow parameterizing the existing PHY package code.
- Enable Rx hashing (RSS) on GTP protocol fields.
Misc:
- Improvements and refactoring all over networking selftests.
- Create uniform module aliases for TC classifiers, actions, and
packet schedulers to simplify creating modprobe policies.
- Address all missing MODULE_DESCRIPTION() warnings in networking.
- Extend the Netlink descriptions in YAML to cover message
encapsulation or "Netlink polymorphism", where interpretation of
nested attributes depends on link type, classifier type or some
other "class type".
Drivers:
- Ethernet high-speed NICs:
- Add a new driver for Marvell's Octeon PCI Endpoint NIC VF.

x86/rfds: Mitigate Register File Data Sampling (RFDS)
RFDS is a CPU vulnerability that may allow userspace to infer kernel stale data previously used in floating point registers, vector registers and integer registers. RFDS only affects certain Intel Atom processors. Intel released a microcode update that uses VERW instruction to clear the affected CPU buffers. Unlike MDS, none of the affected cores support SMT. Add RFDS bug infrastructure and enable the VERW based mitigation by default, that clears the affected buffers just before exiting to userspace. Also add sysfs reporting and cmdline parameter "reg_file_data_sampling" to control the mitigation.

drm/panfrost: Replace fdinfo's profiling debugfs knob with sysfs
Debugfs isn't always available in production builds that try to squeeze every single byte out of the kernel image, but we still need a way to toggle the timestamp and cycle counter registers so that jobs can be profiled for fdinfo's drm engine and cycle calculations.

net: dqs: add NIC stall detector based on BQL
softnet_data->time_squeeze is sometimes used as a proxy for host overload or indication of scheduling problems. In practice this statistic is very noisy and has hard to grasp units - e.g. is 10 squeezes a second to be expected, or high? Delaying network (NAPI) processing leads to drops on NIC queues but also RTT bloat, impacting pacing and CA decisions. Stalls are a little hard to detect on the Rx side, because there may simply have not been any packets received in given period of time. Packet timestamps help a little bit, but again we don't know if packets are stale because we're not keeping up or because someone (*cough* cgroups) disabled IRQs for a long time. We can, however, use Tx as a proxy for Rx stalls. Most drivers use combined Rx+Tx NAPIs so if Tx gets starved so will Rx. On the Tx side we know exactly when packets get queued, and completed, so there is no uncertainty. This patch adds stall checks to BQL. Why BQL? Because it's a convenient place to add such checks, already called by most drivers, and it has copious free space in its structures (this patch adds no extra cache references or dirtying to the fast path). The algorithm takes one parameter - max delay AKA stall threshold and increments a counter whenever NAPI got delayed for at least that amount of time. It also records the length of the longest stall. To be precise every time NAPI has not polled for at least stall thrs we check if there were any Tx packets queued between last NAPI run and now - stall_thrs/2. Unlike the classic Tx watchdog this mechanism does not ignore stalls caused by Tx being disabled, or loss of link. I don't think the check is worth the complexity, and stall is a stall, whether due to host overload, flow control, link down... doesn't matter much to the application. We have been running this detector in production at Meta for 2 years, with the threshold of 8ms. It's the lowest value where false positives become rare. There's still a constant stream of reported stalls (especially without the ksoftirqd deferral patches reverted), those who like their stall metrics to be 0 may prefer higher value.

Documentation: leds: Update led-trigger-tty ABI description
The 'led-trigger-tty' uses the same naming in the ABI documentation as

usb: Export BOS descriptor to sysfs
Motivation ---------- The binary device object store (BOS) of a USB device consists of the BOS descriptor followed by a set of device capability descriptors. One that is of interest to users is the platform descriptor. This contains a 128-bit UUID and arbitrary data, and it allows parties outside of USB-IF to add additional metadata about a USB device in a standards-compliant manner. Notable examples include the WebUSB and Microsoft OS 2.0 descriptors. The kernel already retrieves and caches the BOS from USB devices if its bcdUSB is >= 0x0201. Because the BOS is flexible and extensible, we export the entire BOS to sysfs so users can retrieve whatever device capabilities they desire, without requiring USB I/O or elevated permissions. Implementation -------------- Add bos_descriptors attribute to sysfs. This is a binary file and it works the same way as the existing descriptors attribute. The file exists only if the BOS is present in the USB device. Also create a binary attribute group, so the driver core can handle the creation of both the descriptors and bos_descriptors attributes in sysfs.

virtiofs: export filesystem tags through sysfs
The virtiofs filesystem is mounted using a "tag" which is exported by the virtiofs device: # mount -t virtiofs <tag> /mnt The virtiofs driver knows about all the available tags but these are currently not exported to user space. People have asked for these tags to be exported to user space. Most recently Lennart Poettering has asked for it as he wants to scan the tags and mount virtiofs automatically in certain cases. https://gitlab.com/virtio-fs/virtiofsd/-/issues/128 This patch exports tags at /sys/fs/virtiofs/<N>/tag where N is the id of the virtiofs device. The filesystem tag can be obtained by reading this "tag" file. There is also a symlink at /sys/fs/virtiofs/<N>/device that points to the virtiofs device that exports this tag. This patch converts the existing struct virtio_fs into a full kobject. It already had a refcount so it's an easy change. The virtio_fs objects can then be exposed in a kset at /sys/fs/virtiofs/. Note that virtio_fs objects may live slightly longer than we wish for them to be exposed to userspace, so kobject_del() is called explicitly when the underlying virtio_device is removed. The virtio_fs object is freed when all references are dropped (e.g. active mounts) but disappears as soon as the virtiofs device is gone.

mm/cma: add sysfs file 'release_pages_success'
This adds the following new sysfs file tracking the number of successfully released pages from a given CMA heap area. This file will be available via CONFIG_CMA_SYSFS and help in determining active CMA pages available on the CMA heap area. This adds a new 'nr_pages_released' (CONFIG_CMA_SYSFS) into 'struct cma' which gets updated during cma_release(). /sys/kernel/mm/cma/<cma-heap-area>/release_pages_success After this change, an user will be able to find active CMA pages available in a given CMA heap area via the following method. Active pages = alloc_pages_success - release_pages_success That's valuable information for both software designers, and system admins as it allows them to tune the number of CMA pages available in the system. This increases user visibility for allocated CMA area and its utilization.

mm/mempolicy: implement the sysfs-based weighted_interleave interface
Patch series "mm/mempolicy: weighted interleave mempolicy and sysfs extension", v5. Weighted interleave is a new interleave policy intended to make use of heterogeneous memory environments appearing with CXL. The existing interleave mechanism does an even round-robin distribution of memory across all nodes in a nodemask, while weighted interleave distributes memory across nodes according to a provided weight. (Weight = # of page allocations per round) Weighted interleave is intended to reduce average latency when bandwidth is pressured - therefore increasing total throughput. In other words: It allows greater use of the total available bandwidth in a heterogeneous hardware environment (different hardware provides different bandwidth capacity). As bandwidth is pressured, latency increases - first linearly and then exponentially. By keeping bandwidth usage distributed according to available bandwidth, we therefore can reduce the average latency of a cacheline fetch. A good explanation of the bandwidth vs latency response curve: https://mahmoudhatem.wordpress.com/2017/11/07/memory-bandwidth-vs-latency-response-curve/ From the article: ``` Constant region: The latency response is fairly constant for the first 40% of the sustained bandwidth. Linear region: In between 40% to 80% of the sustained bandwidth, the latency response increases almost linearly with the bandwidth demand of the system due to contention overhead by numerous memory requests. Exponential region: Between 80% to 100% of the sustained bandwidth, the memory latency is dominated by the contention latency which can be as much as twice the idle latency or more. Maximum sustained bandwidth : Is 65% to 75% of the theoretical maximum bandwidth. ``` As a general rule of thumb: * If bandwidth usage is low, latency does not increase. It is optimal to place data in the nearest (lowest latency) device. * If bandwidth usage is high, latency increases. It is optimal to place data such that bandwidth use is optimized per-device. This is the top line goal: Provide a user a mechanism to target using the "maximum sustained bandwidth" of each hardware component in a heterogenous memory system. For example, the stream benchmark demonstrates that 1:1 (default) interleave is actively harmful, while weighted interleave can be beneficial. Default interleave distributes data such that too much pressure is placed on devices with lower available bandwidth. Stream Benchmark (vs DRAM, 1 Socket + 1 CXL Device) Default interleave : -78% (slower than DRAM) Global weighting : -6% to +4% (workload dependant) Targeted weights : +2.5% to +4% (consistently better than DRAM) Global means the task-policy was set (set_mempolicy), while targeted means VMA policies were set (mbind2). We see weighted interleave is not always beneficial when applied globally, but is always beneficial when applied to bandwidth-driving memory regions. There are 4 patches in this set: 1) Implement system-global interleave weights as sysfs extension in mm/mempolicy.c. These weights are RCU protected, and a default weight set is provided (all weights are 1 by default). In future work, we intend to expose an interface for HMAT/CDAT code to set reasonable default values based on the memory configuration of the system discovered at boot/hotplug. 2) A mild refactor of some interleave-logic for re-use in the new weighted interleave logic. 3) MPOL_WEIGHTED_INTERLEAVE extension for set_mempolicy/mbind 4) Protect interleave logic (weighted and normal) with the mems_allowed seq cookie. If the nodemask changes while accessing it during a rebind, just retry the access. Included below are some performance and LTP test information, and a sample numactl branch which can be used for testing. = Performance summary = (tests may have different configurations, see extended info below) 1) MLC (W2) : +38% over DRAM. +264% over default interleave.

dax: add a sysfs knob to control memmap_on_memory behavior
Add a sysfs knob for dax devices to control the memmap_on_memory setting if the dax device were to be hotplugged as system memory. The default memmap_on_memory setting for dax devices originating via pmem or hmem is set to 'false' - i.e. no memmap_on_memory semantics, to preserve legacy behavior. For dax devices via CXL, the default is on. The sysfs control allows the administrator to override the above defaults if needed.

ASoC: Intel: avs: Fixes and new platforms support
Merge series from Cezary Rojewski <cezary.rojewski@intel.com>: The avs-driver continues to be utilized on more recent Intel machines. As TGL-based (cAVS 2.5) e.g.: RPL, inherit most of the functionality from previous platforms: SKL <- APL <- CNL <- ICL <- TGL rather than putting everything into a single file, the platform-specific bits are split into cnl/icl/tgl.c files instead. Makes the division clear and code easier to maintain. Layout of the patchset: First are two changes combined together address the sound-clipping problem, present when only one stream is running - specifically one CAPTURE stream. Follow up is naming-scheme adjustment for some of the existing functions what improves code incohesiveness. As existing IPC/IRQ code operates solely on cAVS 1.5 architecture, it needs no abstraction. The situation changes when newer platforms come into the picture. Thus the next two patches abstract the existing IPC/IRQ handlers so that majority of the common code can be re-used. The ICCMAX change stands out a bit - the AudioDSP firmware loading procedure differs on ICL-based platforms (and onwards) and having a separate commit makes the situation clear to the developers who are going to support the solution from LTS perspective. For that reason I decided not to merge it into the commit introducing the icl.c file. |

coresight-tpdm: Add pattern registers support for CMB
Timestamps are requested if the monitor’s CMB data set unit input data matches the value in the Monitor CMB timestamp pattern and mask registers (M_CMB_TPR and M_CMB_TPMR) when CMB timestamp enabled via the timestamp insertion enable register bit(CMB_TIER.PATT_TSENAB). The pattern match trigger output is achieved via setting values into the CMB trigger pattern and mask registers (CMB_XPR and CMB_XPMR). After configuring a pattern through these registers, the TPDM subunit will assert an output trigger every time it receives new input data that matches the configured pattern value. Values in a given bit number of the mask register correspond to the same bit number in the corresponding pattern register.

hwmon: add fault attribute for voltage channels
Sometimes a voltage channel might have an hard failure (eg: a shorted MOSFET). Hence, add a fault attribute to report such failures.

crypto: qat - add auto reset on error
Expose the `auto_reset` sysfs attribute to configure the driver to reset the device when a fatal error is detected. When auto reset is enabled, the driver resets the device when it detects either an heartbeat failure or a fatal error through an interrupt. This patch is based on earlier work done by Shashank Gupta.

crypto: qat - add heartbeat error simulator
Add a mechanism that allows to inject a heartbeat error for testing purposes. A new attribute `inject_error` is added to debugfs for each QAT device. Upon a write on this attribute, the driver will inject an error on the device which can then be detected by the heartbeat feature. Errors are breaking the device functionality thus they require a device reset in order to be recovered. This functionality is not compiled by default, to enable it CRYPTO_DEV_QAT_ERROR_INJECTION must be set.

This patch separates FAULT_BLKADDR_CONSISTENCE from FAULT_BLKADDR, and rename FAULT_BLKADDR to FAULT_BLKADDR_VALIDITY so that we can: a) use FAULT_BLKADDR_CONSISTENCE in f2fs_truncate_data_blocks_range() to simulate inconsistent issue independently, then it can verify fsck repair flow. b) FAULT_BLKADDR_VALIDITY fault will not cause any inconsistent status, we can just use it to check error path handling in kernel side.

usb: gadget: f_fs: expose ready state in configfs
When a USB gadget is configured through configfs with 1 or more f_fs functions, then the logic setting up the gadget configuration has to wait until the user space code (typically separate applications) responsible for those functions have written their descriptors before the gadget can be activated. The f_fs instance already knows if this has been done, so expose it through a "ready" attribute in configfs for easier synchronization.

Some follow-on work remains to hook up this data into core-mm policy, but that is saved for v6.9. The next significant update is unifying how CXL event records (things like background scrub errors) are processed between so called "firmware first" and native error record retrieval. The CXL driver handler that processes the record retrieved from the device mailbox is now the handler for that same record format coming from an EFI/ACPI notification source. This also contains miscellaneous feature updates, like Get Timestamp, and other fixups.

VFIO updates for v6.8-rc1
- Add debugfs support, initially used for reporting device migration
state. (Longfang Liu)
- Fixes and support for migration dirty tracking across multiple IOVA
regions in the pds-vfio-pci driver. (Brett Creeley)
- Improved IOMMU allocation accounting visibility. (Pasha Tatashin)
- Virtio infrastructure and a new virtio-vfio-pci variant driver, which
provides emulation of a legacy virtio interfaces on modern virtio
hardware for virtio-net VF devices where the PF driver exposes
support for legacy admin queues, ie. an emulated IO BAR on an SR-IOV
VF to provide driver ABI compatibility to legacy devices.
(Yishai Hadas & Feng Liu)
- Migration fixes for the hisi-acc-vfio-pci variant driver.
(Shameer Kolothum)
- Kconfig dependency fix for new virtio-vfio-pci variant driver.
(Arnd Bergmann)
