PM: domains: Fix alloc/free in dev_pm_domain_attach|detach_list()
The dev_pm_domain_attach|detach_list() functions are not resource managed,
hence they should not use devm_* helpers to manage allocation/freeing of
data. Let's fix this by converting to the traditional alloc/free functions.

driver core: Add device probe log helper dev_warn_probe()
Some drivers can still provide their functionality to a certain extent even when some of their resource acquisitions eventually fail. In such cases, emitting errors isn't the desired action, but warnings should be emitted instead. To solve this, introduce dev_warn_probe() as a new device probe log helper, which behaves identically as the already existing dev_err_probe(), while it produces warnings instead of errors. The intended use is with the resources that are actually optional for a particular driver. While there, copyedit the kerneldoc for dev_err_probe() a bit, to simplify its wording a bit, and reuse it as the kerneldoc for dev_warn_probe(), with the necessary wording adjustments, of course.

move asm/unaligned.h to linux/unaligned.h

regmap: Specifically test writing 0 as a value to sparse caches
Since 0 can look a lot like a NULL pointer when used in a cache some clever data structures might potentially introduce bugs specific to handling it. Add some explicit testing of storing 0 as a value in a sparse cache, at the minute there are no issues and this will stop any appearing in the future.

Driver core update for 6.12-rc1
Here is a small set of patches for the driver core code for 6.12-rc1.
This set is the one that caused the most delay on my side, due to lots
of last-minute reports of problems in the async shutdown feature that
was added. In the end, I've reverted all of the patches in that series
so we are back to "normal" and the patch set is being reworked for the
next merge window.
Other than the async shutdown patches that were reverted, included in
here are:
- minor driver core cleanups
- minor driver core bus and class api cleanups and simplifications for
some callbacks
- some const markings of structures
- other even more minor cleanups
All of these, including the last minute reverts, have been in
linux-next, but all of the reports of problems in linux-next were before
the reverts happened. After the reverts, all is good.

Char/Misc and other driver changes for 6.12-rc1
Here is the "big" set of char/misc and other driver subsystem changes for 6.12-rc1. Sorry for the delay, conference travel for the past two weeks has this and my other pull requests showing up real late in the cycle. Lots of changes in here, primarily dominated by the usual IIO driver updates and additions, but there are also small driver subsystem updates all over the place. Included in here are: - lots and lots of new IIO drivers and updates to existing ones - interconnect subsystem updates and new drivers - nvmem subsystem updates and new drivers - mhi driver updates - power supply subsystem updates - kobj_type const work for many different small subsystems - comedi driver fix - coresight subsystem and driver updates - fpga subsystem improvements - slimbus fixups - binder new feature addition for "frozen" notifications - lots and lots of other small driver updates and cleanups All of these have been in linux-next for a long time with no reported problems.

The core clk framework is left largely untouched this time around except for
support for the newly ratified DT property 'assigned-clock-rates-u64'. I'm much
more excited about the support for loading DT overlays from KUnit tests so that
we can test how the clk framework parses DT nodes during clk registration. The
clk framework has some places that are highly DeviceTree dependent so this
charts the path to extend the KUnit tests to cover even more framework code in
the future. I've got some more tests on the list that use the DT overlay
support, but they uncovered issues with clk unregistration that I'm still
working on fixing.
Outside the core, the clk driver update pile is dominated by Qualcomm and
Renesas SoCs, making it fairly usual. Looking closer, there are fixes for
things all over the place, like adding missing clk frequencies or moving
defines for the number of clks out of DT binding headers into the drivers.
There are even conversions of DT bindings to YAML and migration away from
strings to describe clk topology. Overall it doesn't look unusual so I expect
the new drivers to be where we'll have fixes in the coming weeks.

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

driver core: fix async device shutdown hang
Modify device_shutdown() so that supplier devices do not wait for
consumer devices to be shut down first when the devlink is sync state
only, since the consumer is not dependent on the supplier in this case.
Without this change, a circular dependency could hang the system.

arch_numa: switch over to numa_memblks
Until now arch_numa was directly translating firmware NUMA information to memblock. Using numa_memblks as an intermediate step has a few advantages: * alignment with more battle tested x86 implementation * availability of NUMA emulation * maintaining node information for not yet populated memory Adjust a few places in numa_memblks to compile with 32-bit phys_addr_t and replace current functionality related to numa_add_memblk() and __node_distance() in arch_numa with the implementation based on numa_memblks and add functions required by numa_emulation.

arch, mm: pull out allocation of NODE_DATA to generic code
Architectures that support NUMA duplicate the code that allocates NODE_DATA on the node-local memory with slight variations in reporting of the addresses where the memory was allocated. Use x86 version as the basis for the generic alloc_node_data() function and call this function in architecture specific numa initialization. Round up node data size to SMP_CACHE_BYTES rather than to PAGE_SIZE like x86 used to do since the bootmem era when allocation granularity was PAGE_SIZE anyway.

arch, mm: move definition of node_data to generic code
Every architecture that supports NUMA defines node_data in the same way: struct pglist_data *node_data[MAX_NUMNODES]; No reason to keep multiple copies of this definition and its forward declarations, especially when such forward declaration is the only thing in include/asm/mmzone.h for many architectures. Add definition and declaration of node_data to generic code and drop architecture-specific versions.

devres: Correclty strip percpu address space of devm_free_percpu() argument
devm_free_percpu() calls devres_release() with a pointer in percpu address space. devres_release() expects pointers in the generic address space, so address space needs to be stripped from the argument. When strict percpu address space checks are enabled, then the current direct cast from the percpu address space to the generic address space fails the compilation on x86_64 with: devres.c🔢32: error: cast to generic address space pointer from disjoint ‘__seg_gs’ address space pointer Add intermediate casts to unsigned long to remove address space of the pointer before casting it to the generic AS, as advised in [1] and [2]. Side note: sparse still requires __force, although the documentation [2] allows casts to unsigned long without __force attribute. Found by GCC's named address space checks. There were no changes in the resulting object file.

driver core: shut down devices asynchronously
Add code to allow asynchronous shutdown of devices, ensuring that each device is shut down before its parents & suppliers. Only devices with drivers that have async_shutdown_enable enabled will be shut down asynchronously. This can dramatically reduce system shutdown/reboot time on systems that have multiple devices that take many seconds to shut down (like certain NVMe drives). On one system tested, the shutdown time went from 11 minutes without this patch to 55 seconds with the patch.

driver core: class: Check namespace relevant parameters in class_register()
Device class has two namespace relevant fields which are usually
associated by the following usage:
struct class {
...
const struct kobj_ns_type_operations *ns_type;
const void *(*namespace)(const struct device *dev);
...
}
if (dev->class && dev->class->ns_type)
dev->class->namespace(dev);
(1) The usage looks weird since it checks @ns_type but calls namespace()
(2) The usage implies both fields have dependency but their dependency
is not currently enforced yet.
It is found for all existing class definitions that the other filed is
also assigned once one is assigned in current kernel tree.
Fixed by enforcing above existing dependency that both fields are required
for a device class to support namespace via parameter checks.

drivers/base: Introduce device_match_t for device finding APIs
There are several drivers/base APIs for finding a specific device, and they currently use the following good type for the @match parameter: int (*match)(struct device *dev, const void *data) Since these operations do not modify the caller-provided @*data, this type is worthy of a dedicated typedef: typedef int (*device_match_t)(struct device *dev, const void *data) Advantages of using device_match_t: - Shorter API declarations and definitions - Prevent further APIs from using a bad type for @match So introduce device_match_t and apply it to the existing (bus|class|driver|auxiliary)_find_device() APIs.

firmware_loader: Block path traversal
Most firmware names are hardcoded strings, or are constructed from fairly
constrained format strings where the dynamic parts are just some hex
numbers or such.
However, there are a couple codepaths in the kernel where firmware file
names contain string components that are passed through from a device or
semi-privileged userspace; the ones I could find (not counting interfaces
that require root privileges) are:
- lpfc_sli4_request_firmware_update() seems to construct the firmware
filename from "ModelName", a string that was previously parsed out of
some descriptor ("Vital Product Data") in lpfc_fill_vpd()
- nfp_net_fw_find() seems to construct a firmware filename from a model
name coming from nfp_hwinfo_lookup(pf->hwinfo, "nffw.partno"), which I
think parses some descriptor that was read from the device.
(But this case likely isn't exploitable because the format string looks
like "netronome/nic_%s", and there shouldn't be any *folders* starting
with "netronome/nic_". The previous case was different because there,
the "%s" is *at the start* of the format string.)
- module_flash_fw_schedule() is reachable from the
ETHTOOL_MSG_MODULE_FW_FLASH_ACT netlink command, which is marked as
GENL_UNS_ADMIN_PERM (meaning CAP_NET_ADMIN inside a user namespace is
enough to pass the privilege check), and takes a userspace-provided
firmware name.
(But I think to reach this case, you need to have CAP_NET_ADMIN over a
network namespace that a special kind of ethernet device is mapped into,
so I think this is not a viable attack path in practice.)
Fix it by rejecting any firmware names containing ".." path components.
For what it's worth, I went looking and haven't found any USB device
drivers that use the firmware loader dangerously.

regmap: kunit: Add coverage of spinlocked regmaps
By default regmap uses a mutex to protect the regmap but we also support other kinds of locking, including spinlocks, which can have an impact especially around allocations. Ensure that we are covering the spinlock case by running tests configured using fast I/O, this causes the core to use a spinlock instead of a mutex. Running every single test would be redundant but cover most of them.

regmap IRQ support for devices with multiple IRQs
Merge series from Matti Vaittinen <mazziesaccount@gmail.com>: Devices can provide multiple interrupt lines. One reason for this is that a device has multiple subfunctions, each providing its own interrupt line. Another reason is that a device can be designed to be used (also) on a system where some of the interrupts can be routed to another processor. A line often further acts as a demultiplex for specific interrupts and has it's respective set of interrupt (status, mask, ack, ...) registers. Regmap supports the handling of these registers and demultiplexing interrupts, but interrupt domain code ends up assigning the same name for the per interrupt line domains This series adds possibility for giving a name suffix for an interrupt Previous discussion can be found from: https://lore.kernel.org/all/87plst28yk.ffs@tglx/ https://lore.kernel.org/all/15685ef6-92a5-41df-9148-1a67ceaec47b@gmail.com/ The domain suffix support added in this series will be used by the ROHM BD96801 ERRB IRQ support code. The BD96801 ERRB support will need the initial BD96801 driver code, which is not yet in irq/core or regmap trees. Thus the user for this new support is not included in the series, but will be sent once the name suffix support gets merged. |

regmap: Allow setting IRQ domain name suffix
When multiple IRQ domains are created from the same device-tree node they will get the same name based on the device-tree path. This will cause a naming collision in debugFS when IRQ domain specific entries are created. The regmap-IRQ creates per instance IRQ domains. This will lead to a domain name conflict when a device which provides more than one interrupt line uses the regmap-IRQ. Add support for specifying an IRQ domain name suffix when creating a regmap-IRQ controller.

driver core: Fix error handling in driver API device_rename()
For class-device, device_rename() failure maybe cause unexpected link name
within its class folder as explained below:
/sys/class/.../old_name -> /sys/devices/.../old_name
device_rename(..., new_name) and failed
/sys/class/.../new_name -> /sys/devices/.../old_name
Fixed by undoing renaming link if renaming kobject failed.

driver core: Fix size calculation of symlink name for devlink_(add|remove)_symlinks()
devlink_(add|remove)_symlinks() kzalloc() memory to save symlink name for both supplier and consumer, but do not explicitly take into account consumer's prefix "consumer:", so cause disadvantages listed below: 1) it seems wrong for the algorithm to calculate memory size 2) readers maybe need to count characters one by one of both prefix strings to confirm calculated memory size 3) it is relatively easy to introduce new bug if either prefix string is modified in future solved by taking into account consumer's prefix as well.

driver core: Fix uevent_show() vs driver detach race
uevent_show() wants to de-reference dev->driver->name. There is no clean
way for a device attribute to de-reference dev->driver unless that
attribute is defined via (struct device_driver).dev_groups. Instead, the
anti-pattern of taking the device_lock() in the attribute handler risks
deadlocks with code paths that remove device attributes while holding
the lock.
This deadlock is typically invisible to lockdep given the device_lock()
is marked lockdep_set_novalidate_class(), but some subsystems allocate a
local lockdep key for @dev->mutex to reveal reports of the form:
======================================================

The observation though is that driver objects are typically much longer
lived than device objects. It is reasonable to perform lockless
de-reference of a @driver pointer even if it is racing detach from a
device. Given the infrequency of driver unregistration, use
synchronize_rcu() in module_remove_driver() to close any potential
races. It is potentially overkill to suffer synchronize_rcu() just to
handle the rare module removal racing uevent_show() event.
Thanks to Tetsuo Handa for the debug analysis of the syzbot report [1].

drivers: cacheinfo: use __free attribute instead of of_node_put()
Introduce the __free attribute for scope-based resource management.
Resources allocated with __free are automatically released at the end of
the scope. This enhancement aims to mitigate memory management issues
associated with forgetting to release resources by utilizing __free
instead of of_node_put().
To introduce this feature, some modifications to the code structure were
necessary. The original pattern:
```
prev = np;
while(...) {
[...]
np = of_find_next_cache_node(np);
of_node_put(prev);
prev = np;
[...]
}
```
has been updated to:
```
while(...) {
[...]
struct device_node __free(device_node) *prev = np;
np = of_find_next_cache_node(np)
[...]
}
```
With this change, the previous node is automatically cleaned up at the end
of each iteration, allowing the elimination of all of_node_put() calls and
some goto statements.

platform: Add test managed platform_device/driver APIs
Introduce KUnit resource wrappers around platform_driver_register(), platform_device_alloc(), and platform_device_add() so that test authors can register platform drivers/devices from their tests and have the drivers/devices automatically be unregistered when the test is done. This makes test setup code simpler when a platform driver or platform device is needed. Add a few test cases at the same time to make sure the APIs work as intended.

Driver core changes for 6.11-rc1
Here is the big set of driver core changes for 6.11-rc1.
Lots of stuff in here, with not a huge diffstat, but apis are evolving
which required lots of files to be touched. Highlights of the changes
in here are:
- platform remove callback api final fixups (Uwe took many releases to
get here, finally!)
- Rust bindings for basic firmware apis and initial driver-core
interactions. It's not all that useful for a "write a whole driver
in rust" type of thing, but the firmware bindings do help out the
phy rust drivers, and the driver core bindings give a solid base on
which others can start their work. There is still a long way to go
here before we have a multitude of rust drivers being added, but
it's a great first step.
- driver core const api changes. This reached across all bus types,
and there are some fix-ups for some not-common bus types that
linux-next and 0-day testing shook out. This work is being done to
help make the rust bindings more safe, as well as the C code, moving
toward the end-goal of allowing us to put driver structures into
read-only memory. We aren't there yet, but are getting closer.
- minor devres cleanups and fixes found by code inspection
- arch_topology minor changes
- other minor driver core cleanups
All of these have been in linux-next for a very long time with no
reported problems.

Merge patch series "Add ACPI NUMA support for RISC-V"
Haibo Xu <haibo1.xu@intel.com> says:
This patch series enable RISC-V ACPI NUMA support which was based on
the recently approved ACPI ECR[1].
Patch 1/4 add RISC-V specific acpi_numa.c file to parse NUMA information
from SRAT and SLIT ACPI tables.
Patch 2/4 add the common SRAT RINTC affinity structure handler.
Patch 3/4 change the ACPI_NUMA to a hidden option since it would be selected
by default on all supported platform.
Patch 4/4 replace pr_info with pr_debug in arch_acpi_numa_init() to avoid
potential boot noise on ACPI platforms that are not NUMA.
Based-on: https://github.com/linux-riscv/linux-riscv/tree/for-next
[1] https://drive.google.com/file/d/1YTdDx2IPm5IeZjAW932EYU-tUtgS08tX/view?usp=sharing
Testing:
Since the ACPI AIA/PLIC support patch set is still under upstream review,
hence it is tested using the poll based HVC SBI console and RAM disk.

ACPI: NUMA: replace pr_info with pr_debug in arch_acpi_numa_init
There are lots of ACPI enabled systems that aren't NUMA and If the firmware didn't provide the SRAT/SLIT, then there will be a message "Failed to initialise from firmware" from arch_acpi_numa_init() which adding noise to the boot on all of those kind of systems. Replace the pr_info with pr_debug in arch_acpi_numa_init() to avoid it.

regmap: maple: work around gcc-14.1 false-positive warning
With gcc-14.1, there is a false-postive -Wuninitialized warning in
regcache_maple_drop:
drivers/base/regmap/regcache-maple.c: In function 'regcache_maple_drop':
drivers/base/regmap/regcache-maple.c:113:23: error: 'lower_index' is used uninitialized [-Werror=uninitialized]
113 | unsigned long lower_index, lower_last;
| ^~~~~~~~~~~
drivers/base/regmap/regcache-maple.c:113:36: error: 'lower_last' is used uninitialized [-Werror=uninitialized]
113 | unsigned long lower_index, lower_last;
| ^~~~~~~~~~
I've created a reduced test case to see if this needs to be reported
as a gcc, but it appears that the gcc-14.x branch already has a change
that turns this into a more sensible -Wmaybe-uninitialized warning, so
I ended up not reporting it so far.
The reduced test case also produces a warning for gcc-13 and gcc-12
but I don't see that with the version in the kernel.

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).

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

spi: Updates for v6.11
There's some quite exciting core work in this release, we've got the
beginnings of support for hardware initiated transfers which is itself
independently useful for optimising fast paths in existing drivers.
We also have a rework of the DMA mapping which allows finer grained
decisions about DMA mapping messages and also helps remove some bodges
that we'd had.
Otherwise it's a fairly quiet release, a few new drivers and features
for existing drivers, together with various cleanups and DT binding
conversions.
One regmap SPI fix made it's way in here too which I should probably
have sent as a regmap fix instead.
- Support for pre-optimising messages, reducing the overhead for
messages that are repeatedly used (eg, reading the interrupt status
from a device). This will also be used for hardware initiated
transfers in future.
- A reworking of how DMA mapping is done, introducing a new helper and
allowing the DMA mapping decision to be done per transfer instead of
per message.
- Support for Atmel SAMA7D64, Freescale LX2160A DSPI and WCH CH341A.

regmap: Updates for v6.11
There's one new feature here, a regmap_multi_reg_read() matching the existing write function which has some IIO users coming. This allows atomic reads from multiple registers without the need to wrap a higher level lock in the client driver just for regmap (which already has locks anyway).

aux-sysfs-irqs
Shay Says:
==========
Introduce auxiliary bus IRQs sysfs
Today, PCI PFs and VFs, which are anchored on the PCI bus, display their
IRQ information in the <pci_device>/msi_irqs/<irq_num> sysfs files. PCI
subfunctions (SFs) are similar to PFs and VFs and these SFs are anchored
on the auxiliary bus. However, these PCI SFs lack such IRQ information
on the auxiliary bus, leaving users without visibility into which IRQs
are used by the SFs. This absence makes it impossible to debug
situations and to understand the source of interrupts/SFs for
performance tuning and debug.
Additionally, the SFs are multifunctional devices supporting RDMA,
network devices, clocks, and more, similar to their peer PCI PFs and
VFs. Therefore, it is desirable to have SFs' IRQ information available
at the bus/device level.
To overcome the above limitations, this short series extends the
auxiliary bus to display IRQ information in sysfs, similar to that of
PFs and VFs.
It adds an 'irqs' directory under the auxiliary device and includes an
<irq_num> sysfs file within it.
For example:
$ ls /sys/bus/auxiliary/devices/mlx5_core.sf.1/irqs/
50 51 52 53 54 55 56 57 58
Patch summary:
patch-1 adds auxiliary bus to support irqs used by auxiliary device
patch-2 mlx5 driver using exposing irqs for PCI SF devices via auxiliary
bus

subfunctions (SFs) are similar to PFs and VFs and these SFs are anchored
on the auxiliary bus. However, these PCI SFs lack such IRQ information
on the auxiliary bus, leaving users without visibility into which IRQs
are used by the SFs. This absence makes it impossible to debug
situations and to understand the source of interrupts/SFs for
performance tuning and debug.
Additionally, the SFs are multifunctional devices supporting RDMA,
network devices, clocks, and more, similar to their peer PCI PFs and
VFs. Therefore, it is desirable to have SFs' IRQ information available
at the bus/device level.
To overcome the above limitations, this short series extends the
auxiliary bus to display IRQ information in sysfs, similar to that of
PFs and VFs.
It adds an 'irqs' directory under the auxiliary device and includes an
<irq_num> sysfs file within it.
For example:
$ ls /sys/bus/auxiliary/devices/mlx5_core.sf.1/irqs/
50 51 52 53 54 55 56 57 58

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) |

driver core: have match() callback in struct bus_type take a const *
In the match() callback, the struct device_driver * should not be changed, so change the function callback to be a const *. This is one step of many towards making the driver core safe to have struct device_driver in read-only memory. Because the match() callback is in all busses, all busses are modified to handle this properly. This does entail switching some container_of() calls to container_of_const() to properly handle the constant *. For some busses, like PCI and USB and HV, the const * is cast away in the match callback as those busses do want to modify those structures at this point in time (they have a local lock in the driver structure.) That will have to be changed in the future if they wish to have their struct device * in read-only-memory. Cc: Rafael J.

CPUs can be present but not-enabled. These CPUs can't be brought online until the firmware policy changes, which comes with an ACPI notification that will register the CPUs.

In the quest to make struct device constant, start by making to_auxiliary_drv() return a constant pointer so that drivers that call this can be fixed up before the driver core changes. As the return type previously was not constant, also fix up all callers that were assuming that the pointer was not going to be a constant one in order to not break the build.

devcoredump: Add dev_coredumpm_timeout()
Add function to set a custom coredump timeout. For Xe driver usage, current 5 minutes timeout may be too short for users to search and understand what needs to be done to capture coredump to report bugs. We have plans to automate(distribute a udev script) it but at the end will be up to distros and users to pack it so having a option to increase the timeout is a safer option. v2: - replace dev_coredump_timeout_set() by dev_coredumpm_timeout() (Mukesh) v3: - make dev_coredumpm() static inline (Johannes) v5: - rename DEVCOREDUMP_TIMEOUT -> DEVCD_TIMEOUT to avoid redefinition in include/net/bluetooth/coredump.h v6: - fix definition of dev_coredumpm_timeout() when CONFIG_DEV_COREDUMP is disabled Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: Mukesh Ojha <quic_mojha@quicinc.com> Cc: Johannes Berg <johannes@sipsolutions.net> Cc: Jonathan Cavitt <jonathan.cavitt@intel.com> Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Reviewed-by: Jonathan Cavitt <jonathan.cavitt@intel.com> Signed-off-by: José Roberto de Souza <jose.souza@intel.com> Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Acked-by: Johannes Berg <johannes@sipsolutions.net> Link: https://patchwork.freedesktop.org/patch/msgid/20240611174716.72660-1-jose.souza@intel.com Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com> |

drivers: arch_topology: use __free attribute instead of of_node_put()
Introduce the __free attribute for scope-based resource management. Resources allocated with __free are automatically released at the end of the scope. This enhancement aims to mitigate memory management issues associated with forgetting to release resources by utilizing __free instead of of_node_put(). The declaration of the device_node used within the do-while loops is moved directly within the loop so that the resource is automatically freed at the end of each iteration.

drivers: core: synchronize really_probe() and dev_uevent()
Synchronize the dev->driver usage in really_probe() and dev_uevent().
These can run in different threads, what can result in the following
race condition for dev->driver uninitialization:
Thread #1:
==========
really_probe() {
...
probe_failed:
...
device_unbind_cleanup(dev) {
...
dev->driver = NULL; // <= Failed probe sets dev->driver to NULL
...
}
...
}
Thread #2:
==========
dev_uevent() {
...
if (dev->driver)
// If dev->driver is NULLed from really_probe() from here on,
// after above check, the system crashes
add_uevent_var(env, "DRIVER=%s", dev->driver->name);
...
}
really_probe() holds the lock, already. So nothing needs to be done
there. dev_uevent() is called with lock held, often, too. But not
always. What implies that we can't add any locking in dev_uevent()
itself. So fix this race by adding the lock to the non-protected
path. This is the path where above race is observed:
dev_uevent+0x235/0x380
uevent_show+0x10c/0x1f0 <= Add lock here
dev_attr_show+0x3a/0xa0
sysfs_kf_seq_show+0x17c/0x250
kernfs_seq_show+0x7c/0x90
seq_read_iter+0x2d7/0x940
kernfs_fop_read_iter+0xc6/0x310
vfs_read+0x5bc/0x6b0
ksys_read+0xeb/0x1b0
__x64_sys_read+0x42/0x50
x64_sys_call+0x27ad/0x2d30
do_syscall_64+0xcd/0x1d0
entry_SYSCALL_64_after_hwframe+0x77/0x7f
Similar cases are reported by syzkaller in
https://syzkaller.appspot.com/bug?extid=ffa8143439596313a85a
But these are regarding the *initialization* of dev->driver
dev->driver = drv;
As this switches dev->driver to non-NULL these reports can be considered
to be false-positives (which should be "fixed" by this commit, as well,
though).
The same issue was reported and tried to be fixed back in 2015 in
https://lore.kernel.org/lkml/1421259054-2574-1-git-send-email-a.sangwan@samsung.com/
already.

platform: Make platform_driver::remove() return void
struct platform_driver::remove returning an integer made driver authors
expect that returning an error code was proper error handling. However
the driver core ignores the error and continues to remove the device
because there is nothing the core could do anyhow and reentering the
remove callback again is only calling for trouble.
To prevent such wrong assumptions, change the return type of the remove
callback to void. This was prepared by introducing an alternative remove
callback returning void and converting all drivers to that. So .remove()
can be changed without further changes in drivers.
This corresponds to step b) of the plan outlined in commit

regmap-i2c: Subtract reg size from max_write
Currently, when an adapter defines a max_write_len quirk, the data will be chunked into data sizes equal to the max_write_len quirk value. But the payload will be increased by the size of the register address before transmission. The resulting value always ends up larger than the limit set by the quirk. Avoid this error by setting regmap's max_write to the quirk's max_write_len minus the number of bytes for the register and padding. This allows the chunking to work correctly for this limited case without impacting other use-cases.

tracing/treewide: Remove second parameter of __assign_str()
With the rework of how the __string() handles dynamic strings where it
saves off the source string in field in the helper structure[1], the
assignment of that value to the trace event field is stored in the helper
value and does not need to be passed in again.
This means that with:
__string(field, mystring)
Which use to be assigned with __assign_str(field, mystring), no longer
needs the second parameter and it is unused. With this, __assign_str()
will now only get a single parameter.
There's over 700 users of __assign_str() and because coccinelle does not
handle the TRACE_EVENT() macro I ended up using the following sed script:
git grep -l __assign_str | while read a ; do
sed -e 's/\(__assign_str([^,]*[^ ,]\) *,[^;]*/\1)/' $a > /tmp/test-file;
mv /tmp/test-file $a;
done
I then searched for __assign_str() that did not end with ';' as those
were multi line assignments that the sed script above would fail to catch.
Note, the same updates will need to be done for:
__assign_str_len()
__assign_rel_str()
__assign_rel_str_len()
I tested this with both an allmodconfig and an allyesconfig (build only for both).

Here is the small set of driver core and kernfs changes for 6.10-rc1. Nothing major here at all, just a small set of changes for some driver core apis, and minor fixups. Included in here are: - sysfs_bin_attr_simple_read() helper added and used - device_show_string() helper added and used All usages of these were acked by the various maintainers. Also in here are: - kernfs minor cleanup - removed unused functions - typo fix in documentation - pay attention to sysfs_create_link() failures in module.c finally. All of these have been in linux-next for a very long time with no reported problems.

regmap: kunit: Fix array overflow in stride() test
Force the max_register of the test regmap to be one register longer than the number of test registers, to prevent an array overflow in the test loop. The test defines num_reg_defaults = 6. With 6 registers and stride == 2 the valid register addresses would be 0, 2, 4, 6, 8, 10. However the loop checks attempting to access the odd address, so on the final register it accesses address 11, and it writes entry [11] of the read/written arrays. Originally this worked because the max_register of the regmap was hardcoded to be BLOCK_TEST_SIZE (== 12). commit |

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.

arch/topology: Fix variable naming to avoid shadowing
Using 'hw_pressure' for local variable name is confusing in regard to the
per-CPU 'hw_pressure' variable that uses the same name:
include/linux/arch_topology.h:DECLARE_PER_CPU(unsigned long, hw_pressure);
... which puts it into a global scope for all code that includes
<linux/topology.h>, shadowing the local variable.
Rename it to avoid compiler confusion & Sparse warnings.

driver core: Add device_show_string() helper for sysfs attributes
For drivers wishing to expose an unsigned long, int or bool at a static memory location in sysfs, the driver core provides ready-made helpers such as device_show_ulong() to be used as ->show() callback. Some drivers need to expose a string and so far they all provide their own ->show() implementation. arch/powerpc/perf/hv-24x7.c went so far as to create a device_show_string() helper but kept it private. Make it public for reuse by other drivers. The pattern seems to be sufficiently frequent to merit a public helper. Add a DEVICE_STRING_ATTR_RO() macro in line with the existing DEVICE_ULONG_ATTR() and similar macros to ease declaration of string attributes.

sched/cpufreq: Rename arch_update_thermal_pressure() => arch_update_hw_pressure()
Now that cpufreq provides a pressure value to the scheduler, rename arch_update_thermal_pressure into HW pressure to reflect that it returns a pressure applied by HW (i.e. with a high frequency change) and not always related to thermal mitigation but also generated by max current limitation as an example. Such high frequency signal needs filtering to be smoothed and provide an value that reflects the average available capacity into the scheduler time scale.

IIO: 1st set of new device support, features and cleanup for 6.10
The Analog Device team (Paul Cercueil and Nuno Sa) have been working on
improving high speed device handling. They have had some support in their
own tree for many years, so it is great to see them bring it to upstream.
Some of that is seen here, with the first output device using the
IIO dmaengine infrastructure and a new DAC backend FPGA IP driver.
This makes use of a new set of interfaces to allow backend and
front end driver communication in a fashion that in theory at least
allows for a single driver for a given ADC / DAC independent of
the IP to which is being used to deal with the data bus and DMA aspects
of working with these devices. It is early days for this new
generic way of handling split devices, but as it's kernel internals only
we can merrily change anything about it as a wider diversity of devices
show up and we get a better feel for what works.
Alongside the usual set of new drivers and features we have
the automatic cleanup of fwnode_handle_put() which didn't quite make
it in last cycle. The equivalent DT version was merged by Rob Herring
via the DT binding tree and one patch using that in IIO can also be
found in this pull request. Rob has been making extensive use of that
infrastructure in the DT core which is good to see and provides more
evidence this basic approach is useful.
In some cases, the IIO driver was converted over from DT only to
using the generic firmware description handling of property.h
including using the new macros. The general preference for IIO
is to use this more generic handling where possible - a bunch of other
drivers have been converted this cycle as well.
New device support
==================
adi,ad7173
- New driver supporting AD7172-2, AD7172-4 AD7173-9, AD7175-2, AD7175-8,
AD7176-2 and AD7177-2 ADCs.
- Follow up fix for an accidental use of logic not instead of bitwise.
adi,ad7944
- New driver supporting AD7944, AD7985 and AD7986 pin compatible ADCs.
- Later patch added use of new spi_optimize_message() to reduce overheads
of setting up a reused message.
- Additional changes later in series reduced code duplication.
adi,ad9739a RF DAC
- New driver for this 14-bit 2.5 GSPS DAC via an LVDS interface.
adi,axi-dac
- Support for this FPGA IP used to send data to high performance DACs over
an interface such as JESD204B/C or parallel interfaces. Used in
conjunction with a DAC driver. The initial user is the ad9739a.
The dmaengine-buffer needed various changes to make it bidirectional.
avago,apds9306
- New driver for this ambient light sensor.
- Fix much later in this pull for an off by 1 error.
New device IDs
==============
For these at most an ID and a instance of chip specific data was needed.
Always nice to see manufacturers sticking to an existing software interface
for new parts.
allwinner,sun20i
- Add support for h616.
invensense,mpu6050
- Add support for ICM42688
maxim,max30102
- Add compatible for MAX30101
ti,dac5571
- Add compatible for DAC081C081
General
=======
fwnode_handle
- Support for cleanup.h based __free(fwnode_handle)
- Loop macro using this for looping over child nodes without needing to
call fwnode_handle_put() in ever early exit from the loop.
- Used in:
* adi,ad3552r
* adi,ad4130
* adi,ad5770r
* adi,ad74413r
* adi,ad7173
* adi,adfm2000
* linear,ltc2688
* linear,ltc2983
* maxim,max11410
* microchip,pac1934
* qcom,spmi-adc
* renesas,rz2gl
* st,ab8500
* st,stm32 (Fix for failure to set return value precedes this patch,
providing an example of why enabling direct returns makes bugs
less likely)
- Conversions to fwnode also using the cleanup logic
* adi,ad7124
* adi,ad7292
* freescale,fsl-imx25-gcq
- Other conversions to fwnode where the new cleanup handling isn't useful
* adi,ad7192
* avia,hx711
* freescale,mma8452
* nxp,fxls8962af
* st,spear
* ti,twl4030
Features
========

IIO: 1st set of new device support, features and cleanup for 6.10
The Analog Device team (Paul Cercueil and Nuno Sa) have been working on
improving high speed device handling. They have had some support in their
own tree for many years, so it is great to see them bring it to upstream.
Some of that is seen here, with the first output device using the
IIO dmaengine infrastructure and a new DAC backend FPGA IP driver.
This makes use of a new set of interfaces to allow backend and
front end driver communication in a fashion that in theory at least
allows for a single driver for a given ADC / DAC independent of
the IP to which is being used to deal with the data bus and DMA aspects
of working with these devices. It is early days for this new
generic way of handling split devices, but as it's kernel internals only
we can merrily change anything about it as a wider diversity of devices
show up and we get a better feel for what works.
Alongside the usual set of new drivers and features we have
the automatic cleanup of fwnode_handle_put() which didn't quite make
it in last cycle. The equivalent DT version was merged by Rob Herring
via the DT binding tree and one patch using that in IIO can also be
found in this pull request. Rob has been making extensive use of that
infrastructure in the DT core which is good to see and provides more
evidence this basic approach is useful.
In some cases, the IIO driver was converted over from DT only to
using the generic firmware description handling of property.h
including using the new macros. The general preference for IIO
is to use this more generic handling where possible - a bunch of other
drivers have been converted this cycle as well.
New device support
==================
adi,ad7173
- New driver supporting AD7172-2, AD7172-4 AD7173-9, AD7175-2, AD7175-8,
AD7176-2 and AD7177-2 ADCs.
- Follow up fix for an accidental use of logic not instead of bitwise.
adi,ad7944
- New driver supporting AD7944, AD7985 and AD7986 pin compatible ADCs.
- Later patch added use of new spi_optimize_message() to reduce overheads
of setting up a reused message.
- Additional changes later in series reduced code duplication.
adi,ad9739a RF DAC
- New driver for this 14-bit 2.5 GSPS DAC via an LVDS interface.
adi,axi-dac
- Support for this FPGA IP used to send data to high performance DACs over
an interface such as JESD204B/C or parallel interfaces. Used in
conjunction with a DAC driver. The initial user is the ad9739a.
The dmaengine-buffer needed various changes to make it bidirectional.
avago,apds9306
- New driver for this ambient light sensor.
- Fix much later in this pull for an off by 1 error.
New device IDs
==============
For these at most an ID and a instance of chip specific data was needed.
Always nice to see manufacturers sticking to an existing software interface
for new parts.
allwinner,sun20i
- Add support for h616.
invensense,mpu6050
- Add support for ICM42688
maxim,max30102
- Add compatible for MAX30101
ti,dac5571
- Add compatible for DAC081C081
General
=======
fwnode_handle
- Support for cleanup.h based __free(fwnode_handle)
- Loop macro using this for looping over child nodes without needing to
call fwnode_handle_put() in ever early exit from the loop.
- Used in:
* adi,ad3552r
* adi,ad4130
* adi,ad5770r
* adi,ad74413r
* adi,ad7173
* adi,adfm2000
* linear,ltc2688
* linear,ltc2983
* maxim,max11410
* microchip,pac1934
* qcom,spmi-adc
* renesas,rz2gl
* st,ab8500
* st,stm32 (Fix for failure to set return value precedes this patch,
providing an example of why enabling direct returns makes bugs
less likely)
- Conversions to fwnode also using the cleanup logic
* adi,ad7124
* adi,ad7292
* freescale,fsl-imx25-gcq
- Other conversions to fwnode where the new cleanup handling isn't useful
* adi,ad7192
* avia,hx711
* freescale,mma8452
* nxp,fxls8962af
* st,spear
* ti,twl4030

regmap: kunit: Add cache-drop test with multiple cache blocks
Add a test case for dropping only some cache blocks and leaving others unchanged. The regmap is divided into 8 register ranges, and only 4 of these are written with values. This creates 4 non-contiguous ranges of registers with cached values. One whole range is then dropped, and part of another range. A cache sync is then performed to check that the correct registers were written, and the correct values were written to these registers.

regmap: kunit: Add more cache-sync tests
Extend the testing of cache-sync. - cache_sync() renamed cache_sync_marked_dirty() for clarity of what conditions it is testing. - cache_sync_defaults() renamed cache_sync_defaults_marked_dirty() for clarity. Added code to write the register back to its default value to check that a dirty sync doesn't write out the default value. - Added cache_sync_after_cache_only(). Tests syncing the cache without calling regcache_mark_dirty(). A register written while in cache-only should be written out by regcache_sync(). - Added cache_sync_default_after_cache_only. This is similar to cache_sync_after_cache_only(), but the register is changed to its default value while in cache-only. Because regcache_mark_dirty() was NOT called, regacache_sync() should write out the register.

regmap: kunit: Add more cache-drop tests
Extend the testing of cache-drop. - Added cache_drop_all_and_sync_marked_dirty(). If all registers are dropped from the cache a regcache_mark_dirty() followed by regcache_sync() should not write anything because the cache is empty. - Added cache_drop_all_and_sync_no_defaults(). This is similar to cache_drop_all_and_sync_marked_dirty() except that regcache_mark_dirty() is NOT called. All registers were dropped so regcache_sync() should not write anything. - Added cache_drop_all_and_sync_has_defaults(). This is the same as cache_drop_all_and_sync_no_defaults() except that the regmap has a table of default values.

regmap: kunit: Run non-sparse cache tests at non-zero register addresses
Change the tests parameterized by real_cache_types_list[] to test at some register addresses that are not 0. The cache_range_window_reg() test has hardcoded address assumptions that are not present in any other tests using real_cache_types_list[] table. So it has been given a separate parameter table, real_cache_types_only_list[], that preserves the original parameterization.

regmap: kunit: Run sparse cache tests at non-zero register addresses
Run the cache_drop() and cache_present() tests at blocks of addresses
that don't start at zero.
This adds a from_reg parameter to struct regmap_test_param. This is
used to set the base address of the register defaults created by
gen_regmap().
Extra entries are added to sparse_cache_types_list[] to test at non-zero
from_reg values. The cache_drop() and cache_present() tests are updated
to test at the given offset.
The aim here is to add test cases to cache_drop() for the bug fixed by

regmap: kunit: Create a struct device for the regmap
Use kunit_device_register() to create a real struct device for the regmap instead of leaving it at NULL. The main reason for this is that it allows context data to be passed into the readable_reg/writable_reg/volatile_reg functions by attaching it to the struct device with dev_set_drvdata(). The gen_regmap() and gen_raw_regmap() functions are updated to take a struct kunit * argument. A new struct regmap_test_priv has been created to hold the struct device created by kunit_device_register(). This allows the struct to be extended in the future to hold more private data for the test suite.

regmap: Add regmap_read_bypassed()
Add a regmap_read_bypassed() to allow reads from the hardware registers
while the regmap is in cache-only mode.
A typical use for this is to keep the cache in cache-only mode until
the hardware has reached a valid state, but one or more status registers
must be polled to determine when this state is reached.
For example, firmware download on the cs35l56 can take several seconds if
there are multiple amps sharing limited bus bandwidth. This is too long
to block in probe() so it is done as a background task. The device must
be soft-reset to reboot the firmware and during this time the registers are
not accessible, so the cache should be in cache-only. But the driver must
poll a register to detect when reboot has completed.

regmap: maple: Fix cache corruption in regcache_maple_drop()
When keeping the upper end of a cache block entry, the entry[] array
must be indexed by the offset from the base register of the block,
i.e. max - mas.index.
The code was indexing entry[] by only the register address, leading
to an out-of-bounds access that copied some part of the kernel
memory over the cache contents.
This bug was not detected by the regmap KUnit test because it only
tests with a block of registers starting at 0, so mas.index == 0.

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.

- 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

Merge tag 'mm-stable-2024-03-13-20-04' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm
Pull MM updates from Andrew Morton:
- 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.

Pull power management updates from Rafael Wysocki:
"From the functional perspective, the most significant change here is
the addition of support for Energy Models that can be updated
dynamically at run time.
There is also the addition of LZ4 compression support for hibernation,
the new preferred core support in amd-pstate, new platforms support in
the Intel RAPL driver, new model-specific EPP handling in intel_pstate
and more.
Apart from that, the cpufreq default transition delay is reduced from
10 ms to 2 ms (along with some related adjustments), the system
suspend statistics code undergoes a significant rework and there is a
usual bunch of fixes and code cleanups all over.

cxl/region: Deal with numa nodes not enumerated by SRAT
For the numa nodes that are not created by SRAT, no memory_target is allocated and is not managed by the HMAT_REPORTING code. Therefore hmat_callback() memory hotplug notifier will exit early on those NUMA nodes. The CXL memory hotplug notifier will need to call node_set_perf_attrs() directly in order to setup the access sysfs attributes. In acpi_numa_init(), the last proximity domain (pxm) id created by SRAT is stored. Add a helper function acpi_node_backed_by_real_pxm() in order to check if a NUMA node id is defined by SRAT or created by CFMWS. node_set_perf_attrs() symbol is exported to allow update of perf attribs for a node. The sysfs path of /sys/devices/system/node/nodeX/access0/initiators/* is created by node_set_perf_attrs() for the various attributes where nodeX is matched to the NUMA node of the CXL region.

base/node / ACPI: Enumerate node access class for 'struct access_coordinate'
Both generic node and HMAT handling code have been using magic numbers to indicate access classes for 'struct access_coordinate'. Introduce enums to enumerate the access0 and access1 classes shared by the two subsystems. Update the function parameters and callers as appropriate to utilize the new enum. Access0 is named to ACCESS_COORDINATE_LOCAL in order to indicate that the access class is for 'struct access_coordinate' between a target node and the nearest initiator node. Access1 is named to ACCESS_COORDINATE_CPU in order to indicate that the access class is for 'struct access_coordinate' between a target node and the nearest CPU node.

Updates for the MSI interrupt subsystem and RISC-V initial MSI support:
- Core and platform-MSI
The core changes have been adopted from previous work which converted
ARM[64] to the new per device MSI domain model, which was merged to
support multiple MSI domain per device. The ARM[64] changes are being
worked on too, but have not been ready yet. The core and platform-MSI
changes have been split out to not hold up RISC-V and to avoid that
RISC-V builds on the scheduled for removal interfaces.
The core support provides new interfaces to handle wire to MSI bridges
in a straight forward way and introduces new platform-MSI interfaces
which are built on top of the per device MSI domain model.
Once ARM[64] is converted over the old platform-MSI interfaces and the
related ugliness in the MSI core code will be removed.
- Drivers:
- Add a new driver for the Andes hart-level interrupt controller
- Rework the SiFive PLIC driver to prepare for MSI suport
- Expand the RISC-V INTC driver to support the new RISC-V AIA
controller which provides the basis for MSI on RISC-V
- A few fixup for the fallout of the core changes.
The actual MSI parts for RISC-V were finalized late and have been
post-poned for the next merge window.

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.

driver core: Add FWLINK_FLAG_IGNORE to completely ignore a fwnode link
A fwnode link between specific supplier-consumer fwnodes can be added multiple times for multiple reasons. If that dependency doesn't exist, deleting the fwnode link once doesn't guarantee that it won't get created again. So, add FWLINK_FLAG_IGNORE flag to mark a fwnode link as one that needs to be completely ignored. Since a fwnode link's flags is an OR of all the flags passed to all the fwnode_link_add() calls to create that specific fwnode link, the FWLINK_FLAG_IGNORE flag is preserved and can be used to mark a fwnode link as on that need to be completely ignored until it is deleted.

PM: sleep: wakeirq: fix wake irq warning in system suspend
When driver uses pm_runtime_force_suspend() as the system suspend callback
function and registers the wake irq with reverse enable ordering, the wake
irq will be re-enabled when entering system suspend, triggering an
'Unbalanced enable for IRQ xxx' warning. In this scenario, the call
sequence during system suspend is as follows:
suspend_devices_and_enter()
-> dpm_suspend_start()
-> dpm_run_callback()
-> pm_runtime_force_suspend()
-> dev_pm_enable_wake_irq_check()
-> dev_pm_enable_wake_irq_complete()
-> suspend_enter()
-> dpm_suspend_noirq()
-> device_wakeup_arm_wake_irqs()
-> dev_pm_arm_wake_irq()
To fix this issue, complete the setting of WAKE_IRQ_DEDICATED_ENABLED flag
in dev_pm_enable_wake_irq_complete() to avoid redundant irq enablement.

crash: split crash dumping code out from kexec_core.c
Currently, KEXEC_CORE select CRASH_CORE automatically because crash codes need be built in to avoid compiling error when building kexec code even though the crash dumping functionality is not enabled. E.g -------------------- CONFIG_CRASH_CORE=y CONFIG_KEXEC_CORE=y CONFIG_KEXEC=y CONFIG_KEXEC_FILE=y --------------------- After splitting out crashkernel reservation code and vmcoreinfo exporting code, there's only crash related code left in kernel/crash_core.c. Now move crash related codes from kexec_core.c to crash_core.c and only build it in when CONFIG_CRASH_DUMP=y. And also wrap up crash codes inside CONFIG_CRASH_DUMP ifdeffery scope, or replace inappropriate CONFIG_KEXEC_CORE ifdef with CONFIG_CRASH_DUMP ifdef in generic kernel files.

PM: runtime: add tracepoint for runtime_status changes
Existing runtime PM ftrace events (`rpm_suspend`, `rpm_resume`, `rpm_return_int`) offer limited visibility into the exact timing of device runtime power state transitions, particularly when asynchronous operations are involved. When the `rpm_suspend` or `rpm_resume` functions are invoked with the `RPM_ASYNC` flag, a return value of 0 i.e., success merely indicates that the device power state request has been queued, not that the device has yet transitioned. A new ftrace event, `rpm_status`, is introduced. This event directly logs the `power.runtime_status` value of a device whenever it changes providing granular tracking of runtime power state transitions regardless of synchronous or asynchronous `rpm_suspend` / `rpm_resume` usage.

mm and cache_info: remove unnecessary CPU cache info update
For each CPU hotplug event, we will update per-CPU data slice size and
corresponding PCP configuration for every online CPU to make the
implementation simple. But, Kyle reported that this takes tens seconds
during boot on a machine with 34 zones and 3840 CPUs.
So, in this patch, for each CPU hotplug event, we only update per-CPU data
slice size and corresponding PCP configuration for the CPUs that share
caches with the hotplugged CPU. With the patch, the system boot time
reduces 67 seconds on the machine.

mm/memory_hotplug: introduce MEM_PREPARE_ONLINE/MEM_FINISH_OFFLINE notifiers
Patch series "implement "memmap on memory" feature on s390".
This series provides "memmap on memory" support on s390 platform. "memmap
on memory" allows struct pages array to be allocated from the hotplugged
memory range instead of allocating it from main system memory.
s390 currently preallocates struct pages array for all potentially
possible memory, which ensures memory onlining always succeeds, but with
the cost of significant memory consumption from the available system
memory during boottime. In certain extreme configuration, this could lead
to ipl failure.
"memmap on memory" ensures struct pages array are populated from self
contained hotplugged memory range instead of depleting the available
system memory and this could eliminate ipl failure on s390 platform.
On other platforms, system might go OOM when the physically hotplugged
memory depletes the available memory before it is onlined. Hence, "memmap
on memory" feature was introduced as described in commit

All of these, except for the documentation update, have been in
linux-next for over a week. The documentation update has been reviewed
for weeks by a group of developers, and in public for a week and the
wording has stabilized for now. If future changes are needed, we can do

platform-msi: Prepare for real per device domains
Provide functions to create and remove per device MSI domains which replace the platform-MSI domains. The new model is that each of the devices which utilize platform-MSI gets now its private MSI domain which is "customized" in size and with a device specific function to write the MSI message into the device. This is the same functionality as platform-MSI but it avoids all the down sides of platform MSI, i.e. the extra ID book keeping, the special data structure in the msi descriptor. Further the domains are only created when the devices are really in use, so the burden is on the usage and not on the infrastructure. Fill in the domain template and provide two functions to init/allocate and remove a per device MSI domain. Until all users and parent domain providers are converted, the init/alloc function invokes the original platform-MSI code when the irqdomain which is associated to the device does not provide MSI parent functionality yet.

PM: domains: Add helper functions to attach/detach multiple PM domains
Attaching/detaching of a device to multiple PM domains has started to become a common operation for many drivers, typically during ->probe() and ->remove(). In most cases, this has lead to lots of boilerplate code in the drivers. To fixup up the situation, let's introduce a pair of helper functions, dev_pm_domain_attach|detach_list(), that driver can use instead of the open-coding. Note that, it seems reasonable to limit the support for these helpers to DT based platforms, at it's the only valid use case for now.

PM: runtime: Simplify pm_runtime_get_if_active() usage
There are two ways to opportunistically increment a device's runtime PM usage count, calling either pm_runtime_get_if_active() or pm_runtime_get_if_in_use(). The former has an argument to tell whether to ignore the usage count or not, and the latter simply calls the former with ign_usage_count set to false. The other users that want to ignore the usage_count will have to explicitly set that argument to true which is a bit cumbersome. To make this function more practical to use, remove the ign_usage_count argument from the function. The main implementation is in a static function called pm_runtime_get_conditional() and implementations of pm_runtime_get_if_active() and pm_runtime_get_if_in_use() are moved to runtime.c.

regmap: kunit: Ensure that changed bytes are actually different
During the cache sync test we verify that values we expect to have been written only to the cache do not appear in the hardware. This works most of the time but since we randomly generate both the original and new values there is a low probability that these values may actually be the same. Wrap get_random_bytes() to ensure that the values are different, there are other tests which should have similar verification that we actually changed something. While we're at it refactor the test to use three changed values rather than attempting to use one of them twice, that just complicates checking that our new values are actually new. We use random generation to try to avoid data dependencies in the tests.

regmap: kunit: fix raw noinc write test wrapping
The raw noinc write test places a known value in the register following the noinc register to verify that it is not disturbed by the noinc write. This test ensures this value is distinct by adding 100 to the second element of the noinc write data. The regmap registers are 16-bit, while the test value is stored in an unsigned int. Therefore, adding 100 may cause the register to wrap while the test value does not, causing the test to fail. This patch fixes this by changing val_test and val_last from unsigned int to u16.

PM: sleep: Move devices to new lists earlier in each suspend phase
During a system-wide suspend of devices, dpm_noirq_suspend_devices(), dpm_suspend_late() and dpm_suspend() move devices from one list to another. They do it with each device after its PM callback in the given suspend phase has run or has been scheduled for asynchronous execution, in case it is deleted from the current list in the meantime. However, devices can be moved to a new list before invoking their PM callbacks (which usually is the case for the devices whose callbacks are executed asynchronously anyway), because doing so does not affect the ordering of that list. In either case, each device is moved to the new list after the previous device has been moved to it or gone away, and if a device is removed, it does not matter which list it is in at that point, because deleting an entry from a list does not change the ordering of the other entries in it. Accordingly, modify the functions mentioned above to move devices to new lists without waiting for their PM callbacks to run regardless of whether or not they run asynchronously.

It also allows suspend_stats_show() to carry out a loop over the counters array to print their values. Because the counters cannot become negative, use unsigned int for representing them.

driver core: fw_devlink: Improve detection of overlapping cycles
fw_devlink can detect most overlapping/intersecting cycles. However it was
missing a few corner cases because of an incorrect optimization logic that
tries to avoid repeating cycle detection for devices that are already
marked as part of a cycle.
Here's an example provided by Xu Yang (edited for clarity):
usb
+-----+
tcpc | |
+-----+ | +--|
| |----------->|EP|
|--+ | | +--|
|EP|<-----------| |
|--+ | | B |
| | +-----+
| A | |
+-----+ |
^ +-----+ |
| | | |
+-----| C |<--+
| |
+-----+
usb-phy
Node A (tcpc) will be populated as device 1-0050.
Node B (usb) will be populated as device 38100000.usb.
Node C (usb-phy) will be populated as device 381f0040.usb-phy.
The description below uses the notation:
consumer --> supplier
child ==> parent
1. Node C is populated as device C. No cycles detected because cycle
detection is only run when a fwnode link is converted to a device link.
2. Node B is populated as device B. As we convert B --> C into a device
link we run cycle detection and find and mark the device link/fwnode
link cycle:
C--> A --> B.EP ==> B --> C
3. Node A is populated as device A. As we convert C --> A into a device
link, we see it's already part of a cycle (from step 2) and don't run
cycle detection. Thus we miss detecting the cycle:
A --> B.EP ==> B --> A.EP ==> A
Looking at it another way, A depends on B in one way:
A --> B.EP ==> B
But B depends on A in two ways and we only detect the first:
B --> C --> A
B --> A.EP ==> A
To detect both of these, we remove the incorrect optimization attempt in
step 3 and run cycle detection even if the fwnode link from which the
device link is being created has already been marked as part of a cycle.

PM: sleep: Simplify dpm_suspended_list walk in dpm_resume()
Notice that devices can be moved to dpm_prepared_list before running their resume callbacks, in analogy with dpm_noirq_resume_devices() and dpm_resume_early(), because doing so will not affect the final ordering of that list. Namely, if a device is the first dpm_suspended_list entry while dpm_list_mtx is held, it has not been removed so far and it cannot be removed until dpm_list_mtx is released, so moving it to dpm_prepared_list at that point is valid. If it is removed later, while its resume callback is running, it will be deleted from dpm_prepared_list without changing the ordering of the other devices in that list. Accordingly, rearrange the while () loop in dpm_resume() to move devices to dpm_prepared_list before running their resume callbacks and implify the locking and device reference counting in it.

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.

Driver core changes for 6.8-rc1
Here are the set of driver core and kernfs changes for 6.8-rc1. Nothing
major in here this release cycle, just lots of small cleanups and some
tweaks on kernfs that in the very end, got reverted and will come back
in a safer way next release cycle.
Included in here are:
- more driver core 'const' cleanups and fixes
- fw_devlink=rpm is now the default behavior
- kernfs tiny changes to remove some string functions
- cpu handling in the driver core is updated to work better on many
systems that add topologies and cpus after booting
- other minor changes and cleanups
All of the cpu handling patches have been acked by the respective
maintainers and are coming in here in one series. Everything has been
in linux-next for a while with no reported issues.

Networking changes for 6.8.
Core & protocols
----------------
- Analyze and reorganize core networking structs (socks, netdev,
netns, mibs) to optimize cacheline consumption and set up
build time warnings to safeguard against future header changes.
This improves TCP performances with many concurrent connections
up to 40%.
- Add page-pool netlink-based introspection, exposing the
memory usage and recycling stats. This helps indentify
bad PP users and possible leaks.
- Refine TCP/DCCP source port selection to no longer favor even
source port at connect() time when IP_LOCAL_PORT_RANGE is set.
This lowers the time taken by connect() for hosts having
many active connections to the same destination.
- Refactor the TCP bind conflict code, shrinking related socket
structs.
- Refactor TCP SYN-Cookie handling, as a preparation step to
allow arbitrary SYN-Cookie processing via eBPF.
- Tune optmem_max for 0-copy usage, increasing the default value
to 128KB and namespecifying it.
- Allow coalescing for cloned skbs coming from page pools, improving
RX performances with some common configurations.
- Reduce extension header parsing overhead at GRO time.
- Add bridge MDB bulk deletion support, allowing user-space to
request the deletion of matching entries.
- Reorder nftables struct members, to keep data accessed by the
datapath first.
- Introduce TC block ports tracking and use. This allows supporting
multicast-like behavior at the TC layer.
- Remove UAPI support for retired TC qdiscs (dsmark, CBQ and ATM) and
classifiers (RSVP and tcindex).
- More data-race annotations.
- Extend the diag interface to dump TCP bound-only sockets.
- Conditional notification of events for TC qdisc class and actions.
- Support for WPAN dynamic associations with nearby devices, to form
a sub-network using a specific PAN ID.
- Implement SMCv2.1 virtual ISM device support.
- Add support for Batman-avd mulicast packet type.
BPF
---
- Tons of verifier improvements:
- BPF register bounds logic and range support along with a large
test suite
- log improvements
- complete precision tracking support for register spills
- track aligned STACK_ZERO cases as imprecise spilled registers. It
improves the verifier "instructions processed" metric from single
digit to 50-60% for some programs
- support for user's global BPF subprogram arguments with few
commonly requested annotations for a better developer experience
- support tracking of BPF_JNE which helps cases when the compiler
transforms (unsigned) "a > 0" into "if a == 0 goto xxx" and the
like
- several fixes
- Add initial TX metadata implementation for AF_XDP with support in
mlx5 and stmmac drivers. Two types of offloads are supported right
now, that is, TX timestamp and TX checksum offload.
- Fix kCFI bugs in BPF all forms of indirect calls from BPF into
kernel and from kernel into BPF work with CFI enabled. This allows
BPF to work with CONFIG_FINEIBT=y.
- Change BPF verifier logic to validate global subprograms lazily
instead of unconditionally before the main program, so they can be
guarded using BPF CO-RE techniques.
- Support uid/gid options when mounting bpffs.
- Add a new kfunc which acquires the associated cgroup of a task
within a specific cgroup v1 hierarchy where the latter is identified
by its id.
- Extend verifier to allow bpf_refcount_acquire() of a map value field
obtained via direct load which is a use-case needed in sched_ext.
- Add BPF link_info support for uprobe multi link along with bpftool
integration for the latter.
- Support for VLAN tag in XDP hints.
- Remove deprecated bpfilter kernel leftovers given the project
is developed in user-space (https://github.com/facebook/bpfilter).
Misc
----
- Support for parellel TC self-tests execution.
- Increase MPTCP self-tests coverage.
- Updated the bridge documentation, including several so-far
undocumented features.
- Convert all the net self-tests to run in unique netns, to
avoid random failures due to conflict and allow concurrent
runs.
- Add TCP-AO self-tests.
- Add kunit tests for both cfg80211 and mac80211.
- Autogenerate Netlink families documentation from YAML spec.
- Add yml-gen support for fixed headers and recursive nests, the
tool can now generate user-space code for all genetlink families
for which we have specs.
- A bunch of additional module descriptions fixes.
- Catch incorrect freeing of pages belonging to a page pool.
Driver API
----------
- Rust abstractions for network PHY drivers; do not cover yet the
full C API, but already allow implementing functional PHY drivers
in rust.
- Introduce queue and NAPI support in the netdev Netlink interface,
allowing complete access to the device <> NAPIs <> queues
relationship.

Merge tag 'net-next-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Paolo Abeni:
"The most interesting thing is probably the networking structs
reorganization and a significant amount of changes is around
self-tests.
Core & protocols:
- Analyze and reorganize core networking structs (socks, netdev,
netns, mibs) to optimize cacheline consumption and set up build
time warnings to safeguard against future header changes
This improves TCP performances with many concurrent connections up
to 40%
- Add page-pool netlink-based introspection, exposing the memory
usage and recycling stats. This helps indentify bad PP users and
possible leaks
- Refine TCP/DCCP source port selection to no longer favor even
source port at connect() time when IP_LOCAL_PORT_RANGE is set. This
lowers the time taken by connect() for hosts having many active
connections to the same destination
- Refactor the TCP bind conflict code, shrinking related socket
structs
- Refactor TCP SYN-Cookie handling, as a preparation step to allow
arbitrary SYN-Cookie processing via eBPF
- Tune optmem_max for 0-copy usage, increasing the default value to
128KB and namespecifying it
- Allow coalescing for cloned skbs coming from page pools, improving
RX performances with some common configurations
- Reduce extension header parsing overhead at GRO time
- Add bridge MDB bulk deletion support, allowing user-space to
request the deletion of matching entries
- Reorder nftables struct members, to keep data accessed by the
datapath first
- Introduce TC block ports tracking and use. This allows supporting
multicast-like behavior at the TC layer
- Remove UAPI support for retired TC qdiscs (dsmark, CBQ and ATM) and
classifiers (RSVP and tcindex)
- More data-race annotations
- Extend the diag interface to dump TCP bound-only sockets
- Conditional notification of events for TC qdisc class and actions

header cleanups for 6.8
The goal is to get sched.h down to a type only header, so the main thing happening in this patchset is splitting out various _types.h headers and dependency fixups, as well as moving some things out of sched.h to better locations. This is prep work for the memory allocation profiling patchset which adds new sched.h interdepencencies. Testing - it's been in -next, and fixes from pretty much all architectures have percolated in - nothing major. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEKnAFLkS8Qha+jvQrE6szbY3KbnYFAmWfBwwACgkQE6szbY3K bnZPwBAAmuRojXaeWxi01IPIOehSGDe68vw44PR9glEMZvxdnZuPOdvE4/+245/L bRKU2WBCjBUokUbV9msIShwRkFTZAmEMPNfPAAsFMA+VXeDYHKB+ZRdwTggNAQ+I SG6fZgh5m0HsewCDxU8oqVHkjVq4fXn0cy+aL6xLEd9gu67GoBzX2pDieS2Kvy6j jnyoKTxFwb+LTQgph0P4EIpq5I2umAsdLwdSR8EJ+8e9NiNvMo1pI00Lx/ntAnFZ JftWUJcMy3TQ5u1GkyfQN9y/yThX1bZK5GvmHS9SJ2Dkacaus5d+xaKCHtRuFS1I 7C6b8PsNgRczUMumBXus44HdlNfNs1yU3lvVxFvBIPE1qC9pYRHrkWIXXIocXLLC oxTEJ6B2G3BQZVQgLIA4fOaxMVhmvKffi/aEZLi9vN9VVosd1a6XNKI6KbyRnXFp GSs9qDqszhn5I3GYNlDNQTc/8UsRlhPFgS6nS0By6QnvxtGi9QkU2tBRBsXvqwCy cLoCYIhc2tvugHvld70dz26umiJ4rnmxGlobStNoigDvIKAIUt1UmIdr1so8P8eH xehnL9ZcOX6xnANDL0AqMFFHV6I58CJynhFdUoXfVQf/DWLGX48mpi9LVNsYBzsI CAwVOAQ0UjGrpdWmJ9ueY/ABYqg9vRjzaDEXQ+MhAYO55CLaVsg= =3tyT -----END PGP SIGNATURE----- Merge tag 'header_cleanup-2024-01-10' of https://evilpiepirate.org/git/bcachefs Pull header cleanups from Kent Overstreet: "The goal is to get sched.h down to a type only header, so the main thing happening in this patchset is splitting out various _types.h headers and dependency fixups, as well as moving some things out of sched.h to better locations.

Merge tag 'pm-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management updates from Rafael Wysocki:
"These add support for new processors (Sierra Forest, Grand Ridge and
Meteor Lake) to the intel_idle driver, make intel_pstate run on
Emerald Rapids without HWP support and adjust it to utilize EPP values
supplied by the platform firmware, fix issues, clean up code and
improve documentation.
The most significant fix addresses deadlocks in the core system-wide
resume code that occur if async_schedule_dev() attempts to run its
argument function synchronously (for example, due to a memory
allocation failure). It rearranges the code in question which may
increase the system resume time in some cases, but this basically is a
removal of a premature optimization. That optimization will be added
back later, but properly this time.
Specifics:
- Add support for the Sierra Forest, Grand Ridge and Meteorlake SoCs
to the intel_idle cpuidle driver (Artem Bityutskiy, Zhang Rui)
- Do not enable interrupts when entering idle in the haltpoll cpuidle

Many singleton patches against the MM code. The patch series which
are included in this merge do the following:
- Peng Zhang has done some mapletree maintainance work in the
series
"maple_tree: add mt_free_one() and mt_attr() helpers"
"Some cleanups of maple tree"
- In the series "mm: use memmap_on_memory semantics for dax/kmem"
Vishal Verma has altered the interworking between memory-hotplug
and dax/kmem so that newly added 'device memory' can more easily
have its memmap placed within that newly added memory.
- Matthew Wilcox continues folio-related work (including a few
fixes) in the patch series
"Add folio_zero_tail() and folio_fill_tail()"
"Make folio_start_writeback return void"
"Fix fault handler's handling of poisoned tail pages"
"Convert aops->error_remove_page to ->error_remove_folio"
"Finish two folio conversions"
"More swap folio conversions"
- Kefeng Wang has also contributed folio-related work in the series
"mm: cleanup and use more folio in page fault"
- Jim Cromie has improved the kmemleak reporting output in the
series "tweak kmemleak report format".
- In the series "stackdepot: allow evicting stack traces" Andrey
Konovalov to permits clients (in this case KASAN) to cause
eviction of no longer needed stack traces.
- Charan Teja Kalla has fixed some accounting issues in the page
allocator's atomic reserve calculations in the series "mm:
page_alloc: fixes for high atomic reserve caluculations".
- Dmitry Rokosov has added to the samples/ dorectory some sample
code for a userspace memcg event listener application. See the
series "samples: introduce cgroup events listeners".
- Some mapletree maintanance work from Liam Howlett in the series
"maple_tree: iterator state changes".
- Nhat Pham has improved zswap's approach to writeback in the
series "workload-specific and memory pressure-driven zswap
writeback".
- DAMON/DAMOS feature and maintenance work from SeongJae Park in
the series
"mm/damon: let users feed and tame/auto-tune DAMOS"
"selftests/damon: add Python-written DAMON functionality tests"
"mm/damon: misc updates for 6.8"
- Yosry Ahmed has improved memcg's stats flushing in the series
"mm: memcg: subtree stats flushing and thresholds".
- In the series "Multi-size THP for anonymous memory" Ryan Roberts
has added a runtime opt-in feature to transparent hugepages which

Scheduler changes for v6.8:
- Energy scheduling:
- Consolidate how the max compute capacity is
used in the scheduler and how we calculate
the frequency for a level of utilization.
- Rework interface between the scheduler and
the schedutil governor
- Simplify the util_est logic
- Deadline scheduler:
- Work more towards reducing SCHED_DEADLINE
starvation of low priority tasks (e.g., SCHED_OTHER)
tasks when higher priority tasks monopolize CPU
cycles, via the introduction of 'deadline servers'
(nested/2-level scheduling).
"Fair servers" to make use of this facility are
not introduced yet.
- EEVDF:
- Introduce O(1) fastpath for EEVDF task selection
- NUMA balancing:
- Tune the NUMA-balancing vma scanning logic some more,
to better distribute the probability
of a particular vma getting scanned.
- Plus misc fixes, cleanups and updates.

class: fix use-after-free in class_register()
The lock_class_key is still registered and can be found in
lock_keys_hash hlist after subsys_private is freed in error
handler path.A task who iterate over the lock_keys_hash
later may cause use-after-free.So fix that up and unregister
the lock_class_key before kfree(cp).
On our platform, a driver fails to kset_register because of
creating duplicate filename '/class/xxx'.With Kasan enabled,
it prints a invalid-access bug report.
KASAN bug report:
BUG: KASAN: invalid-access in lockdep_register_key+0x19c/0x1bc

As CONFIG_KASAN_GENERIC is not set, Kasan reports invalid-access
not use-after-free here.In this case, modprobe is manipulating
the corrupted lock_keys_hash hlish where lock_class_key is already
freed before.
It's worth noting that this only can happen if lockdep is enabled,
which is not true for normal system.
Fixes:

PM: clk: make pm_clk_add_notifier() take a const pointer
The driver core wants to work with const struct bus_type, so there's no reason that pm_clk_add_notifier() should not also do the same thing, considering that it just passes the pointer off to the driver core which is expecting a const *.

PM: sleep: Fix possible deadlocks in core system-wide PM code
It is reported that in low-memory situations the system-wide resume core code deadlocks, because async_schedule_dev() executes its argument function synchronously if it cannot allocate memory (and not only in that case) and that function attempts to acquire a mutex that is already held. Executing the argument function synchronously from within dpm_async_fn() may also be problematic for ordering reasons (it may cause a consumer device's resume callback to be invoked before a requisite supplier device's one, for example). Address this by changing the code in question to use async_schedule_dev_nocall() for scheduling the asynchronous execution of device suspend and resume functions and to directly run them synchronously if async_schedule_dev_nocall() returns false.

arm64/amu: Use capacity_ref_freq() to set AMU ratio
Use the new capacity_ref_freq() method to set the ratio that is used by AMU for computing the arch_scale_freq_capacity(). This helps to keep everything aligned using the same reference for computing CPUs capacity. The default value of the ratio (stored in per_cpu(arch_max_freq_scale)) ensures that arch_scale_freq_capacity() returns max capacity until it is set to its correct value with the cpu capacity and capacity_ref_freq().

sched/topology: Add a new arch_scale_freq_ref() method
Create a new method to get a unique and fixed max frequency. Currently
cpuinfo.max_freq or the highest (or last) state of performance domain are
used as the max frequency when computing the frequency for a level of
utilization, but:
- cpuinfo_max_freq can change at runtime. boost is one example of
such change.
- cpuinfo.max_freq and last item of the PD can be different leading to
different results between cpufreq and energy model.
We need to save the reference frequency that has been used when computing
the CPUs capacity and use this fixed and coherent value to convert between
frequency and CPU's capacity.
In fact, we already save the frequency that has been used when computing
the capacity of each CPU. We extend the precision to save kHz instead of
MHz currently and we modify the type to be aligned with other variables
used when converting frequency to capacity and the other way.

base/node / acpi: Change 'node_hmem_attrs' to 'access_coordinates'
Dan Williams suggested changing the struct 'node_hmem_attrs' to 'access_coordinates' [1]. The struct is a container of r/w-latency and r/w-bandwidth numbers. Moving forward, this container will also be used by CXL to store the performance characteristics of each link hop in the PCIE/CXL topology. So, where node_hmem_attrs is just the access parameters of a memory-node, access_coordinates applies more broadly to hardware topology characteristics. The observation is that seemed like an exercise in having the application identify "where" it falls on a spectrum of bandwidth and latency needs. For the tuple of read/write-latency and read/write-bandwidth, "coordinates" is not a perfect fit. Sometimes it is just conveying values in isolation and not a "location" relative to other performance points, but in the end this data is used to identify the performance operation point of a given memory-node.

regmap: fix kcalloc() arguments order
When compiling with gcc version 14.0.0 20231220 (experimental)
and W=1, I've noticed a bunch of four similar warnings like:
drivers/base/regmap/regmap-ram.c: In function '__regmap_init_ram':
drivers/base/regmap/regmap-ram.c:68:37: warning: 'kcalloc' sizes specified with
'sizeof' in the earlier argument and not in the later argument [-Wcalloc-transposed-args]
68 | data->read = kcalloc(sizeof(bool), config->max_register + 1,
| ^~~~
Since 'n' and 'size' arguments of 'kcalloc()' are multiplied to
calculate the final size, their actual order doesn't affect the
result and so this is not a bug. But it's still worth to fix it.

rtc: Extend timeout for waiting for UIP to clear to 1s
Specs don't say anything about UIP being cleared within 10ms. They
only say that UIP won't occur for another 244uS. If a long NMI occurs
while UIP is still updating it might not be possible to get valid
data in 10ms.
This has been observed in the wild that around s2idle some calls can
take up to 480ms before UIP is clear.
Adjust callers from outside an interrupt context to wait for up to a
1s instead of 10ms.

base/node.c: initialize the accessor list before registering
The current code registers the node as available in the node array
before initializing the accessor list. This makes it so that
anything which might access the accessor list as a result of
allocations will cause an undefined memory access.
In one example, an extension to access hmat data during interleave
caused this undefined access as a result of a bulk allocation
that occurs during node initialization but before the accessor
list is initialized.
Initialize the accessor list before making the node generally
available to the global system.

mm/memory_hotplug: add missing mem_hotplug_lock
From Documentation/core-api/memory-hotplug.rst:
When adding/removing/onlining/offlining memory or adding/removing
heterogeneous/device memory, we should always hold the mem_hotplug_lock
in write mode to serialise memory hotplug (e.g. access to global/zone
variables).
mhp_(de)init_memmap_on_memory() functions can change zone stats and
struct page content, but they are currently called w/o the
mem_hotplug_lock.
When memory block is being offlined and when kmemleak goes through each
populated zone, the following theoretical race conditions could occur:
CPU 0: | CPU 1:
memory_offline() |
-> offline_pages() |
-> mem_hotplug_begin() |
... |
-> mem_hotplug_done() |
| kmemleak_scan()
| -> get_online_mems()
| ...
-> mhp_deinit_memmap_on_memory() |
[not protected by mem_hotplug_begin/done()]|
Marks memory section as offline, | Retrieves zone_start_pfn
poisons vmemmap struct pages and updates | and struct page members.
the zone related data |
| ...
| -> put_online_mems()
Fix this by ensuring mem_hotplug_lock is taken before performing
mhp_init_memmap_on_memory(). Also ensure that
mhp_deinit_memmap_on_memory() holds the lock.
online/offline_pages() are currently only called from
memory_block_online/offline(), so it is safe to move the locking there.

drivers: base: Use present CPUs in GENERIC_CPU_DEVICES
Three of the five ACPI architectures create sysfs entries using register_cpu() for present CPUs, whereas arm64, riscv and all GENERIC_CPU_DEVICES do this for possible CPUs. Registering a CPU is what causes them to show up in sysfs. It makes very little sense to register all possible CPUs. Registering a CPU is what triggers the udev notifications allowing user-space to react to newly added CPUs. To allow all five ACPI architectures to use GENERIC_CPU_DEVICES, change it to use for_each_present_cpu(). Making the ACPI architectures use GENERIC_CPU_DEVICES is a pre-requisite step to centralise their register_cpu() logic, before moving it into the ACPI processor driver. When we add support for register CPUs from ACPI in a later patch, we will avoid registering CPUs in this path. Of the ACPI architectures that register possible CPUs, arm64 and riscv do not support making possible CPUs present as they use the weak 'always fails' version of arch_register_cpu(). Only two of the eight architectures that use GENERIC_CPU_DEVICES have a distinction between present and possible CPUs. The following architectures use GENERIC_CPU_DEVICES but are not SMP, so possible == present: * m68k * microblaze * nios2 The following architectures use GENERIC_CPU_DEVICES and consider possible == present: * csky: setup_smp() * processor_probe() sets possible for all CPUs and present for all CPUs except the boot cpu, which will have been done by init/main.c::start_kernel(). um appears to be a subarchitecture of x86. The remaining architecture using GENERIC_CPU_DEVICES are: * openrisc and hexagon: where smp_init_cpus() makes all CPUs < NR_CPUS possible, whereas smp_prepare_cpus() only makes CPUs < setup_max_cpus present. After this change, openrisc and hexagon systems that use the max_cpus command line argument would not see the other CPUs present in sysfs. This should not be a problem as these CPUs can't be brought online as _cpu_up() checks cpu_present(). After this change, only CPUs which are present appear in sysfs.

arch_topology: Make register_cpu_capacity_sysctl() tolerant to late CPUs
register_cpu_capacity_sysctl() adds a property to sysfs that describes the CPUs capacity. This is done from a subsys_initcall() that assumes all possible CPUs are registered. With CPU hotplug, possible CPUs aren't registered until they become present, (or for arm64 enabled). This leads to messages during boot: | register_cpu_capacity_sysctl: too early to get CPU1 device! and once these CPUs are added to the system, the file is missing. Move this to a cpuhp callback, so that the file is created once CPUs are brought online. This covers CPUs that are added late by mechanisms like hotplug. One observable difference is the file is now missing for offline CPUs.

arm64: irq: set the correct node for VMAP stack
In current code, init_irq_stacks() will call cpu_to_node().
The cpu_to_node() depends on percpu "numa_node" which is initialized in:
arch_call_rest_init() --> rest_init() -- kernel_init()
--> kernel_init_freeable() --> smp_prepare_cpus()
But init_irq_stacks() is called in init_IRQ() which is before
arch_call_rest_init().
So in init_irq_stacks(), the cpu_to_node() does not work, it
always return 0. In NUMA, it makes the node 1 cpu accesses the IRQ stack which
is in the node 0.
This patch fixes it by:
1.) export the early_cpu_to_node(), and use it in the init_irq_stacks().
2.) change init_irq_stacks() to __init function.

devcoredump: Send uevent once devcd is ready
dev_coredumpm() creates a devcoredump device and adds it
to the core kernel framework which eventually end up
sending uevent to the user space and later creates a
symbolic link to the failed device. An application
running in userspace may be interested in this symbolic
link to get the name of the failed device.
In a issue scenario, once uevent sent to the user space
it start reading '/sys/class/devcoredump/devcdX/failing_device'
to get the actual name of the device which might not been
created and it is in its path of creation.
To fix this, suppress sending uevent till the failing device
symbolic link gets created and send uevent once symbolic
link is created successfully.

write does not touch adjacent registers. This test succeeds with [1]
applied and fails without it.

regmap: ram: support noinc semantics
Support noinc semantics in RAM backed regmaps, for testing purposes. Add a new callback that selects registers which should have noinc behavior. Bulk writes to a noinc register will cause the last value in the buffer to be assigned to the register, while bulk reads will copy the same value repeatedly into the buffer. This patch only adds support to regmap-raw-ram, since regmap-ram does not support bulk operations.

sysctl-6.7-rc1
To help make the move of sysctls out of kernel/sysctl.c not incur a size
penalty sysctl has been changed to allow us to not require the sentinel, the
final empty element on the sysctl array. Joel Granados has been doing all this
work. On the v6.6 kernel we got the major infrastructure changes required to
support this. For v6.7-rc1 we have all arch/ and drivers/ modified to remove
the sentinel. Both arch and driver changes have been on linux-next for a bit
less than a month. It is worth re-iterating the value:
- this helps reduce the overall build time size of the kernel and run time
memory consumed by the kernel by about ~64 bytes per array
- the extra 64-byte penalty is no longer inncurred now when we move sysctls
out from kernel/sysctl.c to their own files
For v6.8-rc1 expect removal of all the sentinels and also then the unneeded
check for procname == NULL.
The last 2 patches are fixes recently merged by Krister Johansen which allow
us again to use softlockup_panic early on boot. This used to work but the
alias work broke it. This is useful for folks who want to detect softlockups
super early rather than wait and spend money on cloud solutions with nothing
but an eventual hung kernel. Although this hadn't gone through linux-next it's
also a stable fix, so we might as well roll through the fixes now.

SoC driver updates for 6.7
The highlights for the driver support this time are
- Qualcomm platforms gain support for the Qualcomm Secure Execution
Environment firmware interface to access EFI variables on certain
devices, and new features for multiple platform and firmware drivers.
- Arm FF-A firmware support gains support for v1.1 specification features,
in particular notification and memory transaction descriptor changes.
- SCMI firmware support now support v3.2 features for clock and DVFS
configuration and a new transport for Qualcomm platforms.
- Minor cleanups and bugfixes are added to pretty much all the active
platforms: qualcomm, broadcom, dove, ti-k3, rockchip, sifive, amlogic,
atmel, tegra, aspeed, vexpress, mediatek, samsung and more.
In particular, this contains portions of the treewide conversion to
use __counted_by annotations and the device_get_match_data helper.

devices, and new features for multiple platform and firmware
drivers.
- Arm FF-A firmware support gains support for v1.1 specification
features, in particular notification and memory transaction
descriptor changes.
- SCMI firmware support now support v3.2 features for clock and DVFS
configuration and a new transport for Qualcomm platforms.
- Minor cleanups and bugfixes are added to pretty much all the active
platforms: qualcomm, broadcom, dove, ti-k3, rockchip, sifive,
amlogic, atmel, tegra, aspeed, vexpress, mediatek, samsung and
more.
In particular, this contains portions of the treewide conversion to
use __counted_by annotations and the device_get_match_data helper"

regmap: prevent noinc writes from clobbering cache
Currently, noinc writes are cached as if they were standard incrementing
writes, overwriting unrelated register values in the cache. Instead, we
want to cache the last value written to the register, as is done in the
accelerated noinc handler (regmap_noinc_readwrite).

firmware_loader: Abort all upcoming firmware load request once reboot triggered
There could be following scenario where there is a ongoing reboot
is going from processA which tries to call all the reboot notifier
callback and one of them is firmware reboot call which tries to
abort all the ongoing firmware userspace request under fw_lock but
there could be another processB which tries to do request firmware,
which came just after abort done from ProcessA and ask for userspace
to load the firmware and this can stop the ongoing reboot ProcessA
to stall for next 60s(default timeout) which may not be expected
behaviour everyone like to see, instead we should abort any firmware
load request which came once firmware knows about the reboot through
notification.

regmap: Ensure range selector registers are updated after cache sync
When we sync the register cache we do so with the cache bypassed in order to avoid overhead from writing the synced values back into the cache. If the regmap has ranges and the selector register for those ranges is in a register which is cached this has the unfortunate side effect of meaning that the physical and cached copies of the selector register can be out of sync after a cache sync. The cache will have whatever the selector was when the sync started and the hardware will have the selector for the register that was synced last. Fix this by rewriting all cached selector registers after every sync, ensuring that the hardware and cache have the same content. This will result in extra writes that wouldn't otherwise be needed but is simple so hopefully robust. We don't read from the hardware since not all devices have physical read support. Given that nobody noticed this until now it is likely that we are rarely if ever hitting this case.

regmap: kunit: Add test for cache sync interaction with ranges
Hector Martin reports that since when doing a cache sync we enable cache bypass if the selector register for a range is cached then we might leave the physical selector register pointing to a different value to that which we have in the cache. If we then try to write to the page that our cache tells us is selected we will not update the selector register and write to the wrong page. Add a test case covering this.

cacheinfo: calculate size of per-CPU data cache slice
This can be used to estimate the size of the data cache slice that can be used by one CPU under ideal circumstances. Both DATA caches and UNIFIED caches are used in calculation. So, the users need to consider the impact of the code cache usage. Because the cache inclusive/non-inclusive information isn't available now, we just use the size of the per-CPU slice of LLC to make the result more predictable across architectures. This may be improved when more cache information is available in the future. A brute-force algorithm to iterate all online CPUs is used to avoid to allocate an extra cpumask, especially in offline callback.

Moreover, let's add a function, dev_pm_domain_set_performance_state(), that may be called by consumers to request a new performance state for a device through its PM domain. Note that, in most cases it's preferred that a consumer use the OPP library to request a new performance state for its device.

This would only have affected devices with a register stride other than 1 but would corrupt data on those devices. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmUcVmcACgkQJNaLcl1U h9A4sgf+K/KziZcfrjzZhsuQ02qfNVDwBrYcsJCW8CjomFq1kb7QMwX1NgDkZRRD +RbBuPvj1t/BMzsePJWrY7wDcOQHPijQPeOufcz6ZxASX0LQN3SCQR2GV+JJJSXb XW0RLws6WcpG15XZvV8ddxYgeIeAKOhrECZg8bcHvsdin5rU19H4FydiLDS7ZCvV jN1XYtwtFosaV/Zi28cE5nOJ3xFZeYzzx6SbdpCiQSY4llqiMxVBfffpS3wDQHWb hLHDHeiD/kNqS+sDVDsHEOgHiWMv1JN8P6pNvPMdNqVDAgq5lVlAB3zex1pFCTV9 FRVBTgKLZEafeMqIpMus6WJe0oKCTQ== =LK1Y -----END PGP SIGNATURE----- Merge tag 'regmap-fix-v6.6-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap Pull regmap fix from Mark Brown: "A fix for a long standing issue where when we create a new node in an rbtree register cache we were failing to convert the register address of the new register into a bitmask correctly and marking the wrong register as being present in the newly created node.

regmap: rbtree: Fix wrong register marked as in-cache when creating new node
When regcache_rbtree_write() creates a new rbtree_node it was passing the
wrong bit number to regcache_rbtree_set_register(). The bit number is the
offset __in number of registers__, but in the case of creating a new block
regcache_rbtree_write() was not dividing by the address stride to get the
number of registers.
Fix this by dividing by map->reg_stride.
Compare with regcache_rbtree_read() where the bit is checked.
This bug meant that the wrong register was marked as present. The register
that was written to the cache could not be read from the cache because it
was not marked as cached. But a nearby register could be marked as having
a cached value even if it was never written to the cache.

PM: domains: Allow genpd providers to manage OPP tables directly by its FW
In some cases the OPP tables aren't specified in device tree, but rather encoded in the FW. To allow a genpd provider to specify them dynamically instead, let's add a new genpd flag, GENPD_FLAG_OPP_TABLE_FW.

This pull request is full of clk driver changes. In fact, there aren't any
changes to the clk framework this time around. That's probably because everyone
was on vacation (yours truly included). We did lose a couple clk drivers this
time around because nobody was using those devices. That skews the diffstat a
bit, but either way, nothing looks out of the ordinary here. The usual suspects
are chugging along adding support for more SoCs and fixing bugs.
If I had to choose, I'd say the theme for the past few months has been
"polish". There's quite a few patches that migrate to
devm_platform_ioremap_resource() in here. And there's more than a handful of
patches that move the NR_CLKS define from the DT binding header to the driver.
There's even patches that migrate drivers to use clk_parent_data and clk_hw to
describe clk tree topology. It seems that the spring (summer?) cleaning bug got
some folks, or the semiconductor shortage finally hit the software side.
New Drivers:
- StarFive JH7110 SoC clock drivers
- Qualcomm IPQ5018 Global Clock Controller driver
- Versa3 clk generator to support 48KHz playback/record with audio codec on
RZ/G2L SMARC EVK
Removed Drivers:
- Remove non-OF mmp clk drivers
- Remove OXNAS clk driver
Updates:
- Add __counted_by to struct clk_hw_onecell_data and struct spmi_pmic_div_clk_cc
- Move defines for numbers of clks (NR_CLKS) from DT headers to drivers
- Introduce kstrdup_and_replace() and use it
- Add PLL rates for Rockchip rk3568
- Add the display clock tree for Rockchip rv1126
- Add Audio Clock Generator (ADG) clocks on Renesas R-Car Gen3 and RZ/G2 SoCs
- Convert sun9i-mmc clock to use devm_platform_get_and_ioremap_resource()
- Fix function name in a comment in ccu_mmc_timing.c
- Parameter name correction for ccu_nkm_round_rate()
- Implement CLK_SET_RATE_PARENT for Allwinner NKM clocks, i.e. consider alternative
parent rates when determining clock rates
- Set CLK_SET_RATE_PARENT for Allwinner A64 pll-mipi
- Support finding closest (as opposed to closest but not higher) clock rate
for NM, NKM, mux and div type clocks, as use it for Allwinner A64 pll-video0
- Prefer current parent rate if able to generate ideal clock rate for Allwinner NKM clocks
- Clean up Qualcomm SMD RPM driver, with interconnect bus clocks moved out to
the interconnect drivers
- Fix various PM runtime bugs across many Qualcomm clk drivers
- Migrate Qualcomm MDM9615 is to parent_hw and parent_data
- Add network related resets on Qualcomm IPQ4019
- Add a couple missing USB related clocks to Qualcomm IPQ9574
- Add missing gpll0_sleep_clk_src to Qualcomm MSM8917 global clock controller
- In the Qualcomm QDU1000 global clock controller, GDSCs, clkrefs, and GPLL1 are
added, while PCIe pipe clock, SDCC rcg ops are corrected
- Add missing GDSCs to and correct GDSCs for the SC8280XP global clock controller driver
- Support retention for the Qualcomm SC8280XP display clock controller GDSCs.
- Qualcommm's SDCC apps_clk_src is marked with CLK_OPS_PARENT_ENABLE to fix
issues with missing parent clocks across sc7180, sm7150, sm6350 and sm8250,
while sm8450 is corrected to use floor ops

- Add graphics clock support on Renesas RZ/G2M, RZ/G2N, RZ/G2E, and R-Car H3,
M3-W, and M3-N SoCs
- Add Clocked Serial Interface (CSI) clocks on Renesas RZ/V2M
- Add PWM (MTU3) clock and reset on Renesas RZ/G2UL and RZ/Five
- Add the PDM IPC clock for i.MX93
- Add 519.75MHz frequency support for i.MX9 PLL
- Simplify the .determine_rate() implementation for i.MX GPR mux

Devicetree updates for v6.6:
DT core:
- Add support for generating DT nodes for PCI devices. This is the
groundwork for applying overlays to PCI devices containing
non-discoverable downstream devices.
- DT unittest additions to check reverted changesets, to test for
refcount issues, and to test unresolved symbols. Also, various
clean-ups of the unittest along the way.
- Refactor node and property manipulation functions to better share code
with old API and changeset API
- Refactor changeset print functions to a common implementation
- Move some platform_device specific functions into of_platform.c
Bindings:
- Treewide fixing of typos
- Treewide clean-up of SPDX tags to use 'OR' consistently
- Last chunk of dropping unnecessary quotes. With that, the check
for unnecessary quotes is enabled in yamllint.
- Convert ftgmac100, zynqmp-genpd, pps-gpio, syna,rmi4, and qcom,ssbi
bindings to DT schema format
- Add Allwinner V3s xHCI USB, Saef SF-TC154B display, QCom SM8450 Inline
Crypto Engine, QCom SM6115 UFS, QCom SDM670 PDC interrupt controller,
Arm 2022 Cortex cores, and QCom IPQ9574 Crypto bindings
- Fixes for Rockchip DWC PCI binding
- Ensure all properties are evaluated on USB connector schema
- Fix dt-check-compatible script to find of_device_id instances with
compiler annotations

regmap: Updates for v6.6
This is a much quieter release than the past few, there's one small API
addition that I noticed a user for in ALSA and a bunch of cleanups:
- Provide an interface for determining if a register is present in the
cache and add a user of it in ALSA.
- Full support for dynamic allocations, following the temporary bodges
that were done as fixes in the previous release.
- Remove the unused and questionably working 64 bit support.

crash: memory and CPU hotplug sysfs attributes
Introduce the crash_hotplug attribute for memory and CPUs for use by
userspace. These attributes directly facilitate the udev rule for
managing userspace re-loading of the crash kernel upon hot un/plug
changes.
For memory, expose the crash_hotplug attribute to the
/sys/devices/system/memory directory. For example:
# udevadm info --attribute-walk /sys/devices/system/memory/memory81
looking at device '/devices/system/memory/memory81':
KERNEL=="memory81"
SUBSYSTEM=="memory"
DRIVER==""
ATTR{online}=="1"
ATTR{phys_device}=="0"
ATTR{phys_index}=="00000051"
ATTR{removable}=="1"
ATTR{state}=="online"
ATTR{valid_zones}=="Movable"
looking at parent device '/devices/system/memory':
KERNELS=="memory"
SUBSYSTEMS==""
DRIVERS==""
ATTRS{auto_online_blocks}=="offline"
ATTRS{block_size_bytes}=="8000000"
ATTRS{crash_hotplug}=="1"
For CPUs, expose the crash_hotplug attribute to the
/sys/devices/system/cpu directory. For example:
# udevadm info --attribute-walk /sys/devices/system/cpu/cpu0
looking at device '/devices/system/cpu/cpu0':
KERNEL=="cpu0"
SUBSYSTEM=="cpu"
DRIVER=="processor"
ATTR{crash_notes}=="277c38600"
ATTR{crash_notes_size}=="368"
ATTR{online}=="1"
looking at parent device '/devices/system/cpu':
KERNELS=="cpu"
SUBSYSTEMS==""
DRIVERS==""
ATTRS{crash_hotplug}=="1"
ATTRS{isolated}==""
ATTRS{kernel_max}=="8191"
ATTRS{nohz_full}==" (null)"
ATTRS{offline}=="4-7"
ATTRS{online}=="0-3"
ATTRS{possible}=="0-7"
ATTRS{present}=="0-3"
With these sysfs attributes in place, it is possible to efficiently
instruct the udev rule to skip crash kernel reloading for kernels
configured with crash hotplug support.
For example, the following is the proposed udev rule change for RHEL
system 98-kexec.rules (as the first lines of the rule file):
# The kernel updates the crash elfcorehdr for CPU and memory changes
SUBSYSTEM=="cpu", ATTRS{crash_hotplug}=="1", GOTO="kdump_reload_end"
SUBSYSTEM=="memory", ATTRS{crash_hotplug}=="1", GOTO="kdump_reload_end"
When examined in the context of 98-kexec.rules, the above rules test if
crash_hotplug is set, and if so, the userspace initiated
unload-then-reload of the crash kernel is skipped.
CPU and memory checks are separated in accordance with CONFIG_HOTPLUG_CPU
and CONFIG_MEMORY_HOTPLUG kernel config options. If an architecture
supports, for example, memory hotplug but not CPU hotplug, then the
/sys/devices/system/memory/crash_hotplug attribute file is present, but
the /sys/devices/system/cpu/crash_hotplug attribute file will NOT be
present. Thus the udev rule skips userspace processing of memory hot
un/plug events, but the udev rule will evaluate false for CPU events, thus
allowing userspace to process CPU hot un/plug events (ie the
unload-then-reload of the kdump capture kernel).

With memmap on memory, some architecture needs more details w.r.t altmap such as base_pfn, end_pfn, etc to unmap vmemmap memory. Instead of computing them again when we remove a memory block, embed vmem_altmap details in struct memory_block if we are using memmap on memory block feature.

drivers: base: Free devm resources when unregistering a device
In the current code, devres_release_all() only gets called if the device has a bus and has been probed. This leads to issues when using bus-less or driver-less devices where the device might never get freed if a managed resource holds a reference to the device. This is happening in the DRM framework for example. We should thus call devres_release_all() in the device_del() function to make sure that the device-managed actions are properly executed when the device is unregistered, even if it has neither a bus nor a driver. This is effectively the same change than commit |

drivers: base: Add basic devm tests for platform devices
Platform devices show some inconsistencies with how devm resources are released when the device has been probed and when it hasn't. In particular, we can register device-managed actions no matter if the device has be bound to a driver or not, but devres_release_all() will only be called if it was bound to a driver or if there's no reference held to it anymore. If it wasn't bound to a driver and we still have a reference, devres_release_all() will never get called. This is surprising considering that if the driver isn't bound but doesn't have any reference to it anymore, that function will get called, and if it was bound to a driver but still has references, that function will get called as well. Even if that case is fairly unusual, it can easily lead to memory leaks. The plan is, with the next patch, to make it consistent and enforce that devres_release_all() is called no matter what situation we're in. For now, it just tests for the current behaviour and skips over the inconsistencies.

drivers: base: Add basic devm tests for root devices
The root devices show some odd behaviours compared to regular "bus" devices that have been probed through the usual mechanism, so let's create kunit tests to exercise those paths and odd cases. It's not clear whether root devices are even allowed to use device managed resources, but the fact that it works in some cases but not others like shown in that test suite shouldn't happen either way: we want to make it consistent and documented. These tests will (after the following patches) ensure that consistency and effectively document that it's allowed. If it ever turns out to be a bad idea, we can always roll back and modify the tests then.
