tsm for 6.16
- Add a general sysfs scheme for publishing "Measurement" values
provided by the architecture's TEE Security Manager. Use it to publish
TDX "Runtime Measurement Registers" ("RTMRs") that either maintain a
hash of stored values (similar to a TPM PCR) or provide statically
provisioned data. These measurements are validated by a relying party.
- Reorganize the drivers/virt/coco/ directory for "host" and "guest"
shared infrastructure.
- Fix a configfs-tsm-report unregister bug
- With CONFIG_TSM_MEASUREMENTS joining CONFIG_TSM_REPORTS and in
anticipation of more shared "TSM" infrastructure arriving, rename the
maintainer entry to "TRUSTED SECURITY MODULE (TSM) INFRASTRUCTURE".

arm64 updates for 6.16
ACPI, EFI and PSCI:
- Decouple Arm's "Software Delegated Exception Interface" (SDEI)
support from the ACPI GHES code so that it can be used by platforms
booted with device-tree.
- Remove unnecessary per-CPU tracking of the FPSIMD state across EFI
runtime calls.
- Fix a node refcount imbalance in the PSCI device-tree code.
CPU Features:
- Ensure register sanitisation is applied to fields in ID_AA64MMFR4.
- Expose AIDR_EL1 to userspace via sysfs, primarily so that KVM guests
can reliably query the underlying CPU types from the VMM.
- Re-enabling of SME support (CONFIG_ARM64_SME) as a result of fixes
to our context-switching, signal handling and ptrace code.
Entry code:
- Hook up TIF_NEED_RESCHED_LAZY so that CONFIG_PREEMPT_LAZY can be
selected.
Memory management:
- Prevent BSS exports from being used by the early PI code.
- Propagate level and stride information to the low-level TLB
invalidation routines when operating on hugetlb entries.
- Use the page-table contiguous hint for vmap() mappings with
VM_ALLOW_HUGE_VMAP where possible.
- Optimise vmalloc()/vmap() page-table updates to use "lazy MMU mode"
and hook this up on arm64 so that the trailing DSB (used to publish
the updates to the hardware walker) can be deferred until the end of
the mapping operation.
- Extend mmap() randomisation for 52-bit virtual addresses (on par with
48-bit addressing) and remove limited support for randomisation of
the linear map.
Perf and PMUs:
- Add support for probing the CMN-S3 driver using ACPI.
- Minor driver fixes to the CMN, Arm-NI and amlogic PMU drivers.
Selftests:
- Fix FPSIMD and SME tests to align with the freshly re-enabled SME
support.
- Fix default setting of the OUTPUT variable so that tests are
installed in the right location.
vDSO:
- Replace raw counter access from inline assembly code with a call to
the the __arch_counter_get_cntvct() helper function.
Miscellaneous:
- Add some missing header inclusions to the CCA headers.
- Rework rendering of /proc/cpuinfo to follow the x86-approach and
avoid repeated buffer expansion (the user-visible format remains
identical).
- Remove redundant selection of CONFIG_CRC32
- Extend early error message when failing to map the device-tree blob.

Pull power management updates from Rafael Wysocki:
"Once again, the changes are dominated by cpufreq updates, but this
time the majority of them are cpufreq core changes, mostly related to
the introduction of policy locking guards and __free() usage, and
fixes related to boost handling.
Still, there is also a significant update of the intel_pstate driver
making it register an energy model when running on a hybrid platform
which is used for enabling energy-aware scheduling (EAS) if the driver
operates in the passive mode (and schedutil is used as the cpufreq
governor for all CPUs which is the passive mode default).
There are some amd-pstate driver updates too, for a good measure,
including the "Requested CPU Min frequency" BIOS option support and
new online/offline callbacks.
In the cpuidle space, the most significant change is the addition of a
C1 demotion on/off sysfs knob to intel_idle which should help some
users to configure their systems more precisely. There is also the
conversion of the PSCI cpuidle driver to a faux device one and there
are two small updates of cpuidle governors.
Device power management is also modified quite a bit, especially the
handling of devices with asynchronous suspend and resume enabled
during system transitions. They are now going to be handled more
asynchronously during suspend transitions and somewhat less
aggressively during resume transitions.
Apart from the above, the operating performance points (OPP) library
is now going to use mutex locking guards and scope-based cleanup
helpers and there is the usual bunch of assorted fixes and code
cleanups.

"The most significant part of these changes is an ACPICA update
covering two upstream ACPICA releases, 20241212 and 20250404, that
have not been included into the kernel code base yet.
Among other things, it adds definitions needed to address GCC 15's
-Wunterminated-string-initialization warnings, adds support for three
new tables (MRRM, ERDT, RIMT), extends support for two tables (RAS2,
DMAR), and fixes some issues.
On top of the above, there is a new parser for the MRRM table, more
changes related to GCC 15's -Wunterminated-string-initialization
warnings, a CPPC library update including functions related to
autonomous CPU performance state selection, a couple of new quirks,
some assorted fixes and some code cleanups.

Pull erofs updates from Gao Xiang:
"In this cycle, Intel QAT hardware accelerators are supported to
improve DEFLATE decompression performance. I've tested it with the
enwik9 dataset of 1 MiB pclusters on our Intel Sapphire Rapids
bare-metal server and a PL0 ESSD, and the sequential read performance
even surpasses LZ4 software decompression on this setup.
In addition, a `fsoffset` mount option is introduced for file-backed
mounts to specify the filesystem offset in order to adapt customized
container formats.
And other improvements and minor cleanups. Summary:
- Add a `fsoffset` mount option to specify the filesystem offset
- Support Intel QAT accelerators to boost up the DEFLATE algorithm
- Initialize per-CPU workers and CPU hotplug hooks lazily to avoid
unnecessary overhead when EROFS is not mounted
- Fix file handle encoding for 64-bit NIDs
- Minor cleanups"
* tag 'erofs-for-6.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs:

erofs: support DEFLATE decompression by using Intel QAT
This patch introduces the use of the Intel QAT to offload EROFS data
decompression, aiming to improve the decompression performance.
A 285MiB dataset is used with the following command to create EROFS
images with different cluster sizes:
$ mkfs.erofs -zdeflate,level=9 -C{4096,16384,65536,131072,262144}
Fio is used to test the following read patterns:
$ fio -filename=testfile -bs=4k -rw=read -name=job1
$ fio -filename=testfile -bs=4k -rw=randread -name=job1
$ fio -filename=testfile -bs=4k -rw=randread --io_size=14m -name=job1
Here are some performance numbers for reference:
Processors: Intel(R) Xeon(R) 6766E (144 cores)

PCI/AER: Add sysfs attributes for log ratelimits
Allow userspace to read/write log ratelimits per device (including
enable/disable). Create aer/ sysfs directory to store them and any
future AER configs.
The new sysfs files are:
/sys/bus/pci/devices/*/aer/correctable_ratelimit_burst
/sys/bus/pci/devices/*/aer/correctable_ratelimit_interval_ms
/sys/bus/pci/devices/*/aer/nonfatal_ratelimit_burst
/sys/bus/pci/devices/*/aer/nonfatal_ratelimit_interval_ms
The default values are ratelimit_burst=10, ratelimit_interval_ms=5000, so
if we try to emit more than 10 messages in a 5 second period, some are
suppressed.
Update AER sysfs ABI filename to reflect the broader scope of AER sysfs
attributes (e.g. stats and ratelimits).
Documentation/ABI/testing/sysfs-bus-pci-devices-aer_stats ->
sysfs-bus-pci-devices-aer
Tested using aer-inject[1]. Configured correctable log ratelimit to 5.
Sent 6 AER errors. Observed 5 errors logged while AER stats
(cat /sys/bus/pci/devices/<dev>/aer_dev_correctable) shows 6.
Disabled ratelimiting and sent 6 more AER errors. Observed all 6 errors
logged and accounted in AER stats (12 total errors).
[1] https://git.kernel.org/pub/scm/linux/kernel/git/gong.chen/aer-inject.git
[bhelgaas: note fatal errors are not ratelimited, "aer_report" ->
"aer_info", replace ratelimit_log_enable toggle with *_ratelimit_interval_ms]

IIO: New device support, features and cleanup for 6.16 - take 2
Note - last minute rebase was to drop a typo patch that I'd accidentally picked up (in the microblaze arch Kconfig) Take 2 is due to that rebase messing up some fixes tags that were referring to patches after that point. There is a known merge conflict due to changes in neighbouring lines. Stephen's resolution in linux-next is: https://lore.kernel.org/linux-next/20250506155728.65605bae@canb.auug.org.au/ Added 3 named IIO reviewers to MAINTAINERS. This is a reflection of those who have been doing much of this work for some time. Lars-Peter is removed from the entry having moved on to other topics. Thanks Nuno, David and Andy for stepping up and Lars-Peter for all your hard work in the past! Includes the usual mix of new device support, features and general cleanup. This time we also have some tree wide changes. - Rip out the iio_device_claim_direct_scoped() as it proved hard to work with. This series includes quite a few related cleanups such as use of guard or factoring code out to allow direct returns. - Switch from iio_device_claim/release_direct_mode() to new iio_device_claim/release_direct() which is structured so that sparse can warn on failed releases. There were a few false positives but those were mostly in code that benefited from being cleaned up as part of this process. - Introduce iio_push_to_buffers_with_ts() to replace the _timestamp() version over time. This version takes the size of the supplied buffer which the core checks is at least as big as expected by calculation from channel descriptions of those channels enabled. Use this in an initial set of drivers. - Add macros for IIO_DECLARE_BUFFER_WITH_TS() and IIO_DECLARE_DMA_BUFFER_WITH_TS() to avoid lots of fiddly code to ensure correctly aligned buffers for timestamps being added onto the end of channel data. New device support ------------------ adi,ad3530r - New driver for AD3530, AD3530R, AD3531 and AD3531R DACs with programmable gain controls. R variants have internal references. adi,ad7476 - Add support (dt compatible only) for the Rohm BU79100G ADC which is fully compatible with the ti,ads7866. adi,ad7606 - Support ad7606c-16 and ad7606c-18 devices. Includes switch to dynamic channel information allocation. adi,ad7380 - Add support for the AD7389-4 dfrobot,sen0322 - New driver for this oxygen sensor. mediatek,mt2701-auxadc - Add binding for MT6893 which is fully compatible with already supported MT8173. meson-saradc - Support the GXLX SoCs. Mostly this is a workaround for some unrelated clock control bits found in the ADC register map. nuvoton,nct7201 - New driver for NCT7201 and NCT7202 I2C ADCs. rohm,bd79124 - New driver for this 12-bit, 8-channel SAR ADC. - Switch to new set_rv etc gpio callbacks that were added in 6.15. rohm,bd79703 - Add support for BD79700, BD79701 and BD79702 DACs that have subsets of functionality of the already supported bd79703. Included making this driver suitable for support device variants. st,stm32-lptimer - Add support for stm32pm25 to this trigger. Features -------- Beyond IIO - Property iterator for named children. core - Enable writes for 64 bit integers used for standard IIO ABI elements. Previously these could be read only. - Helper library that should avoid code duplication for simpler ADC bindings that have a child node per channel. - Enforce that IIO_DMA_MINALIGN is always at least 8 (almost always true and simplifies code on all significant architectures) core/backend - Add support to control source of data - useful when the HDL includes things like generated ramps for testing purposes. Enable this for adi-axi-dac adi,ad3552-hs - Add debugfs related callbacks to allow debug access to register contents. adi,ad4000 - Support SPI offload with appropriate FPGA firmware along with improving documentation. adi,ad7293 - Add support for external reference voltage. adi,ad7606 - Support SPI offload. adi,ad7768-1 - Support reset GPIO. adi,admv8818 - Support filter frequencies beyond 2^32. adi,adxl345 - Add single and double tap events. hid-sensor-prox - Support 16-bit report sizes as seen on some Intel platforms. invensense,icm42600 - Enable use of named interrupts to avoid problems with some wiring choices.

Includes some general driver cleanup and a separate dt binding. - Simplify reference voltage handling by assuming it is fixed after enabling the supply. winsen,mhz19b - New driver for this C02 sensor. Cleanup and minor fixes ----------------------- dt-bindings - Correct indentation and style for DTS examples. - Use unevalutateProperties for SPI devices instead of additionalProperties to allow generic SPI properties from spi-peripheral-props.yaml ABI Docs - Add missing docs for sampling_frequency when it applies only to events. Treewide - Various minor tweaks, comment fixes and similar. - Sort TI ADCs in Kconfig that had gotten out of order. - Switch various drives that provide GPIO chip functionality to the new callbacks with return values. - Standardize on { } formatting for all array sentinels. - Make use of aligned_s64 in a few places to replace either wrong types or manually defined equivalents. - Drop places where spi bits_per_word is set to 8 because that is the default anyway. adi,ad_sigma_delta library - Avoid a potential use of uninitialized data if reg_size has a value that is not supported (no drivers hit this but it is reasonable hardening) adi,ad4030 - Add error checking for scan types and no longer store it in state. - Rework code to reduce duplication. - Move setting the mode from buffer preenable() to update_scan_mode(), better matching expected semantics of the two different callbacks. - Improve data marshalling comments. adi,ad4695 - Use u16 for buffer elements as oversampling is not yet supported except with SPI offload (which doesn't use this path). adi,ad5592r - Clean up destruction of mutexes. - Use lock guards to simplify code (later patch fixes a missed unlock) adi,ad5933 - Correct some incorrect settling times. adi,ad7091 - Deduplicate handling of writable vs volatile registers as they are the inverse of each other for this device. adi,ad7124 - Fix 3db Filter frequency. - Remove ability to directly write the filter frequency (which was broken) - Register naming improvements. adi,ad7606 - Add a missing return value check. - Fill in max sampling rates for all chips. - Use devm_mutex_init() - Fix up some kernel-doc formatting issues. - Remove some camel case that snuck in. - Drop setting address field in channels as easily established from other fields. - Drop unnecessary parameter to ad76060_scale_setup_cb_t. adi,ad7768-1 - Convert to regmap. - Factor out buffer allocation. - Tidy up headers. adi,ad7944 - Stop setting bits_per_word in SPI xfers with no data. adi,ad9832 - Add of_device_id table rather than just relying on fallbacks. - Use FIELD_PREP() to set values of fields. adi,admv1013 - Cleanup a pointless ternary. adi,admv8818 - Fix up LPF Band 5 frequency which was slightly wrong. - Fix an integer overflow. - Fix range calculation adi,adt7316 - Replace irqd_get_trigger_type(irq_get_irq_data()) with simpler irq_get_trigger_type() adi,adxl345 - Use regmap cache instead of various state variables that were there to reduce bus accesses. - Make regmap return value checking consistent across all call sites. adi,axi-dac - Add a check on number of channels (0 to 15 valid) allwinner,sun20i - Use new adc-helpers to replace local parsing code for channel nodes. bosch,bmp290 - Move to local variables for sensor data marshalling removing the need for a messy definition that has to work for all supported parts.

mm/mempolicy: Weighted Interleave Auto-tuning
On machines with multiple memory nodes, interleaving page allocations across nodes allows for better utilization of each node's bandwidth. Previous work by Gregory Price [1] introduced weighted interleave, which allowed for pages to be allocated across nodes according to user-set ratios. Ideally, these weights should be proportional to their bandwidth, so that under bandwidth pressure, each node uses its maximal efficient bandwidth and prevents latency from increasing exponentially. Previously, weighted interleave's default weights were just 1s -- which would be equivalent to the (unweighted) interleave mempolicy, which goes through the nodes in a round-robin fashion, ignoring bandwidth information. This patch has two main goals: First, it makes weighted interleave easier to use for users who wish to relieve bandwidth pressure when using nodes with varying bandwidth (CXL). By providing a set of "real" default weights that just work out of the box, users who might not have the capability (or wish to) perform experimentation to find the most optimal weights for their system can still take advantage of bandwidth-informed weighted interleave. Second, it allows for weighted interleave to dynamically adjust to hotplugged memory with new bandwidth information. Instead of manually updating node weights every time new bandwidth information is reported or taken off, weighted interleave adjusts and provides a new set of default weights for weighted interleave to use when there is a change in bandwidth information. To meet these goals, this patch introduces an auto-configuration mode for the interleave weights that provides a reasonable set of default weights, calculated using bandwidth data reported by the system. In auto mode, weights are dynamically adjusted based on whatever the current bandwidth information reports (and responds to hotplug events). This patch still supports users manually writing weights into the nodeN sysfs interface by entering into manual mode. When a user enters manual mode, the system stops dynamically updating any of the node weights, even during hotplug events that shift the optimal weight distribution. A new sysfs interface "auto" is introduced, which allows users to switch between the auto (writing 1 or Y) and manual (writing 0 or N) modes. The system also automatically enters manual mode when a nodeN interface is manually written to. There is one functional change that this patch makes to the existing weighted_interleave ABI: previously, writing 0 directly to a nodeN interface was said to reset the weight to the system default. Before this patch, the default for all weights were 1, which meant that writing 0 and 1 were functionally equivalent. With this patch, writing 0 is invalid.

PCI: Add debugfs support for exposing PTM context
Precision Time Management (PTM) mechanism defined in PCIe spec r6.0, sec 6.21 allows precise coordination of timing information across multiple components in a PCIe hierarchy with independent local time clocks. PCI core already supports enabling PTM in the root port and endpoint devices through PTM Extended Capability registers. But the PTM context supported by the PTM capable components such as Root Complex (RC) and Endpoint (EP) controllers were not exposed as of now. Part of the reason is that the spec doesn't define how the context information is exposed to the software and left it to the vendor implementation. So there is no standardized way to get access to the context information and each vendor have defined their own way. This commit adds debugfs support to expose the PTM context to userspace from both PCIe RC and EP controllers. Since the context information is exposed in a vendor specific way, the debugfs interface allows the controller drivers to implement callbacks for each attribute, to be called by the generic PTM driver. The Controller drivers are expected to call pcie_ptm_create_debugfs() to create the debugfs attributes for the PTM context and call pcie_ptm_destroy_debugfs() to destroy them. The drivers should also populate the relevant callbacks in the 'struct pcie_ptm_ops' structure based on the controller implementation. Below PTM context are exposed through debugfs: PCIe RC ======= 1. PTM Local clock 2. PTM T2 timestamp 3. PTM T3 timestamp 4. PTM Context valid PCIe EP ======= 1. PTM Local clock 2. PTM T1 timestamp 3. PTM T4 timestamp 4. PTM Master clock 5.

vmscan,cgroup: apply mems_effective to reclaim
It is possible for a reclaimer to cause demotions of an lruvec belonging to a cgroup with cpuset.mems set to exclude some nodes. Attempt to apply this limitation based on the lruvec's memcg and prevent demotion. Notably, this may still allow demotion of shared libraries or any memory first instantiated in another cgroup. This means cpusets still cannot cannot guarantee complete isolation when demotion is enabled, and the docs have been updated to reflect this. This is useful for isolating workloads on a multi-tenant system from certain classes of memory more consistently - with the noted exceptions. Note on locking: The cgroup_get_e_css reference protects the css->effective_mems, and calls of this interface would be subject to the same race conditions associated with a non-atomic access to cs->effective_mems. So while this interface cannot make strong guarantees of correctness, it can therefore avoid taking a global or rcu_read_lock for performance.

Arm SCMI updates for v6.16
1. Quirk framework to handle buggy firmware
With SCMI gaining broader adoption across arm64 platforms, it's
increasingly important to address how we consistently manage out-of-spec
SCMI firmware already deployed in the field. This change introduces a
lightweight quirk framework built around static_keys, enabling developers to:
- Define quirks and their match criteria, which can include:
o A list of compatibles ({ comp, comp2, NULL })
o Vendor ID / Sub-Vendor ID
o Firmware implementation version ranges ([Min_Vers, Max_Vers])
Matching proceeds from the most specific (longest match) to the least
specific. NULL entries are treated as wildcards (i.e., match any value).
This flexibility allows matching very specific combinations or just a
general compatible string.
The quirk code blocks/snippets implementing the workaround are placed near
their intended usage and guarded by a static_key that's tied to the quirk.
Once the SCMI core stack is initialized and retrieves platform info via the
base protocol, any matching quirks will have their associated static_keys
enabled.
2. Quirk for Qualcomm X1E platforms
On some Qualcomm X1E platforms, such as the Lenovo ThinkPad T14s, the
SCMI firmware fails to set the FastChannel support bit for PERF_LEVEL_GET,
yet it crashes when the driver attempts to fall back to standard messaging
which is clearly out-of-spec behavior.
To work around this, the new SCMI quirk framework is used to
unconditionally enable FC initialization for this firmware version.
In the future, once the fixed firmware version is identified, an upper
version bound can be added to the quirk match criteria. Alternatively,
matching can be further restricted using a SoC-specific compatible string
if always enabling FC proves problematic elsewhere.
3. Support for NXP i.MX LMM/CPU vendor protocol extensions
The i.MX95 System Manager (SM) implements Logical Machine Management (LMM)
and a CPU protocol to manage Logical Machines (LM) and CPUs (e.g., M7).
These changes integrate the vendor-specific protocol extensions
implementing the LMM and CPU protocols for the i.MX95, facilitating
standardized communication between the operating system and the platform's
firmware, which will be used by remoteproc drivers. The changes also
include the necessary device tree bindings.
4. Miscellaneous cleanups/changes
These mainly include polling support in SCMI raw mode. The cleanups
centralize error logging for SCMI device creation into a single helper
function, consolidate the device matching logic into a single function, and
ensure that devices must have a name for registration—removing support for
unnamed devices when matching drivers and devices for probing. Transport
devices are now excluded from bus matching, and the correct assignment of
the parent device for the arm-scmi platform device is ensured in the
transport drivers.

Matching proceeds from the most specific (longest match) to the least
specific. NULL entries are treated as wildcards (i.e., match any value).
This flexibility allows matching very specific combinations or just a
general compatible string.
The quirk code blocks/snippets implementing the workaround are placed near
their intended usage and guarded by a static_key that's tied to the quirk.
Once the SCMI core stack is initialized and retrieves platform info via the
base protocol, any matching quirks will have their associated static_keys
enabled.
2. Quirk for Qualcomm X1E platforms
On some Qualcomm X1E platforms, such as the Lenovo ThinkPad T14s, the
SCMI firmware fails to set the FastChannel support bit for PERF_LEVEL_GET,
yet it crashes when the driver attempts to fall back to standard messaging
which is clearly out-of-spec behavior.
To work around this, the new SCMI quirk framework is used to
unconditionally enable FC initialization for this firmware version.
In the future, once the fixed firmware version is identified, an upper
version bound can be added to the quirk match criteria. Alternatively,
matching can be further restricted using a SoC-specific compatible string
if always enabling FC proves problematic elsewhere.
3. Support for NXP i.MX LMM/CPU vendor protocol extensions
The i.MX95 System Manager (SM) implements Logical Machine Management (LMM)
and a CPU protocol to manage Logical Machines (LM) and CPUs (e.g., M7).
These changes integrate the vendor-specific protocol extensions
implementing the LMM and CPU protocols for the i.MX95, facilitating
standardized communication between the operating system and the platform's
firmware, which will be used by remoteproc drivers. The changes also
include the necessary device tree bindings.
4. Miscellaneous cleanups/changes
These mainly include polling support in SCMI raw mode. The cleanups
centralize error logging for SCMI device creation into a single helper
function, consolidate the device matching logic into a single function, and
ensure that devices must have a name for registration—removing support for
unnamed devices when matching drivers and devices for probing. Transport
devices are now excluded from bus matching, and the correct assignment of
the parent device for the arm-scmi platform device is ensured in the
transport drivers.

x86/its: Enable Indirect Target Selection mitigation
Indirect Target Selection (ITS) is a bug in some pre-ADL Intel CPUs with eIBRS. It affects prediction of indirect branch and RETs in the lower half of cacheline. Due to ITS such branches may get wrongly predicted to a target of (direct or indirect) branch that is located in the upper half of the cacheline. Scope of impact =============== Guest/host isolation -------------------- When eIBRS is used for guest/host isolation, the indirect branches in the VMM may still be predicted with targets corresponding to branches in the guest. Intra-mode ---------- cBPF or other native gadgets can be used for intra-mode training and disclosure using ITS. User/kernel isolation --------------------- When eIBRS is enabled user/kernel isolation is not impacted. Indirect Branch Prediction Barrier (IBPB) ----------------------------------------- After an IBPB, indirect branches may be predicted with targets corresponding to direct branches which were executed prior to IBPB. This is mitigated by a microcode update. Add cmdline parameter indirect_target_selection=off|on|force to control the mitigation to relocate the affected branches to an ITS-safe thunk i.e. located in the upper half of cacheline. Also add the sysfs reporting. When retpoline mitigation is deployed, ITS safe-thunks are not needed, because retpoline sequence is already ITS-safe. Similarly, when call depth tracking (CDT) mitigation is deployed (retbleed=stuff), ITS safe return thunk is not used, as CDT prevents RSB-underflow. To not overcomplicate things, ITS mitigation is not supported with spectre-v2 lfence;jmp mitigation. Moreover, it is less practical to deploy lfence;jmp mitigation on ITS affected parts anyways.

arm64: Expose AIDR_EL1 via sysfs
The KVM PV ABI recently added a feature that allows the VM to discover
the set of physical CPU implementations, identified by a tuple of
{MIDR_EL1, REVIDR_EL1, AIDR_EL1}. Unlike other KVM PV features, the
expectation is that the VMM implements the hypercall instead of KVM as
it has the authoritative view of where the VM gets scheduled.
To do this the VMM needs to know the values of these registers on any
CPU in the system. While MIDR_EL1 and REVIDR_EL1 are already exposed,
AIDR_EL1 is not. Provide it in sysfs along with the other identification
registers.

x86/cpu: Help users notice when running old Intel microcode
Old microcode is bad for users and for kernel developers.
For users, it exposes them to known fixed security and/or functional
issues. These obviously rarely result in instant dumpster fires in
every environment. But it is as important to keep your microcode up
to date as it is to keep your kernel up to date.
Old microcode also makes kernels harder to debug. A developer looking
at an oops need to consider kernel bugs, known CPU issues and unknown
CPU issues as possible causes. If they know the microcode is up to
date, they can mostly eliminate known CPU issues as the cause.
Make it easier to tell if CPU microcode is out of date. Add a list
of released microcode. If the loaded microcode is older than the
release, tell users in a place that folks can find it:
/sys/devices/system/cpu/vulnerabilities/old_microcode
Tell kernel kernel developers about it with the existing taint
flag:
TAINT_CPU_OUT_OF_SPEC
== Discussion ==
When a user reports a potential kernel issue, it is very common
to ask them to reproduce the issue on mainline. Running mainline,
they will (independently from the distro) acquire a more up-to-date
microcode version list. If their microcode is old, they will
get a warning about the taint and kernel developers can take that
into consideration when debugging.
Just like any other entry in "vulnerabilities/", users are free to
make their own assessment of their exposure.
== Microcode Revision Discussion ==
The microcode versions in the table were generated from the Intel
microcode git repo:
8ac9378a8487 ("microcode-20241112 Release")
which as of this writing lags behind the latest microcode-20250211.
It can be argued that the versions that the kernel picks to call "old"
should be a revision or two old. Which specific version is picked is
less important to me than picking *a* version and enforcing it.
This repository contains only microcode versions that Intel has deemed
to be OS-loadable. It is quite possible that the BIOS has loaded a
newer microcode than the latest in this repo. If this happens, the
system is considered to have new microcode, not old.
Specifically, the sysfs file and taint flag answer the question:
Is the CPU running on the latest OS-loadable microcode,
or something even later that the BIOS loaded?
In other words, Intel never publishes an authoritative list of CPUs
and latest microcode revisions. Until it does, this is the best that
Linux can do.
Also note that the "intel-ucode-defs.h" file is simple, ugly and
has lots of magic numbers. That's on purpose and should allow a
single file to be shared across lots of stable kernel regardless of if
they have the new "VFM" infrastructure or not. It was generated with
a dumb script.
== FAQ ==
Q: Does this tell me if my system is secure or insecure?
A: No. It only tells you if your microcode was old when the
system booted.
Q: Should the kernel warn if the microcode list itself is too old?
A: No. New kernels will get new microcode lists, both mainline
and stable. The only way to have an old list is to be running
an old kernel in which case you have bigger problems.
Q: Is this for security or functional issues?
A: Both.
Q: If a given microcode update only has functional problems but
no security issues, will it be considered old?
A: Yes. All microcode image versions within a microcode release
are treated identically. Intel appears to make security
updates without disclosing them in the release notes. Thus,
all updates are considered to be security-relevant.
Q: Who runs old microcode?
A: Anybody with an old distro. This happens all the time inside
of Intel where there are lots of weird systems in labs that
might not be getting regular distro updates and might also
be running rather exotic microcode images.
Q: If I update my microcode after booting will it stop saying
"Vulnerable"?
A: No. Just like all the other vulnerabilies, you need to
reboot before the kernel will reassess your vulnerability.

leds: led-triggers: Improvements for default trigger
Accept "default" written to sysfs trigger attr. If the text "default" is written to the LED's sysfs 'trigger' attr, then call led_trigger_set_default() to set the LED to its default trigger. If the default trigger is set to "none", then led_trigger_set_default() will remove a trigger. This is in contrast to the default trigger being unset, in which case led_trigger_set_default() does nothing.

scsi: ufs: core: Add device level exception support
The ufs device JEDEC specification version 4.1 adds support for the device level exception events. To support this new device level exception feature, expose two new sysfs nodes below to provide the user space access to the device level exception information. /sys/bus/platform/drivers/ufshcd/*/device_lvl_exception_count /sys/bus/platform/drivers/ufshcd/*/device_lvl_exception_id The device_lvl_exception_count sysfs node reports the number of device level exceptions that have occurred since the last time this variable is reset. Writing a value of 0 will reset it. The device_lvl_exception_id reports the exception ID which is the qDeviceLevelExceptionID attribute of the device JEDEC specifications version 4.1 and later. The user space application can query these sysfs nodes to get more information about the device level exception. Signed-off-by: Bao D.

- The 6 patch series "Enable strict percpu address space checks" from
Uros Bizjak uses x86 named address space qualifiers to provide compile-time checking of percpu area accesses. This has caused a small amount of fallout - two or three issues were reported. In all cases the calling code was founf to be incorrect. - The 4 patch series "Some cleanup for memcg" from Chen Ridong implements some relatively monir cleanups for the memcontrol code. - The 17 patch series "mm: fixes for device-exclusive entries (hmm)" from David Hildenbrand fixes a boatload of issues which David found then using device-exclusive PTE entries when THP is enabled. More work is needed, but this makes thins better - our own HMM selftests now succeed. - The 2 patch series "mm: zswap: remove z3fold and zbud" from Yosry Ahmed remove the z3fold and zbud implementations. They have been deprecated for half a year and nobody has complained. - The 5 patch series "mm: further simplify VMA merge operation" from Lorenzo Stoakes implements numerous simplifications in this area. No runtime effects are anticipated. - The 4 patch series "mm/madvise: remove redundant mmap_lock operations from process_madvise()" from SeongJae Park rationalizes the locking in the madvise() implementation. Performance gains of 20-25% were observed in one MADV_DONTNEED microbenchmark. - The 12 patch series "Tiny cleanup and improvements about SWAP code" from Baoquan He contains a number of touchups to issues which Baoquan noticed when working on the swap code. - The 2 patch series "mm: kmemleak: Usability improvements" from Catalin Marinas implements a couple of improvements to the kmemleak user-visible output. - The 2 patch series "mm/damon/paddr: fix large folios access and schemes handling" from Usama Arif provides a couple of fixes for DAMON's handling of large folios. - The 3 patch series "mm/damon/core: fix wrong and/or useless damos_walk() behaviors" from SeongJae Park fixes a few issues with the accuracy of kdamond's walking of DAMON regions. - The 3 patch series "expose mapping wrprotect, fix fb_defio use" from Lorenzo Stoakes changes the interaction between framebuffer deferred-io and core MM. No functional changes are anticipated - this is preparatory work for the future removal of page structure fields. - The 4 patch series "mm/damon: add support for hugepage_size DAMOS filter" from Usama Arif adds a DAMOS filter which permits the filtering by huge page sizes. - The 4 patch series "mm: permit guard regions for file-backed/shmem mappings" from Lorenzo Stoakes extends the guard region feature from its present "anon mappings only" state. The feature now covers shmem and file-backed mappings. - The 4 patch series "mm: batched unmap lazyfree large folios during reclamation" from Barry Song cleans up and speeds up the unmapping for pte-mapped large folios. - The 18 patch series "reimplement per-vma lock as a refcount" from Suren Baghdasaryan puts the vm_lock back into the vma. Our reasons for pulling it out were largely bogus and that change made the code more messy. This patchset provides small (0-10%) improvements on one microbenchmark. - The 5 patch series "Docs/mm/damon: misc DAMOS filters documentation fixes and improves" from SeongJae Park does some maintenance work on the DAMON docs. - The 27 patch series "hugetlb/CMA improvements for large systems" from Frank van der Linden addresses a pile of issues which have been observed when using CMA on large machines. - The 2 patch series "mm/damon: introduce DAMOS filter type for unmapped pages" from SeongJae Park enables users of DMAON/DAMOS to filter my the page's mapped/unmapped status. - The 19 patch series "zsmalloc/zram: there be preemption" from Sergey Senozhatsky teaches zram to run its compression and decompression operations preemptibly. - The 12 patch series "selftests/mm: Some cleanups from trying to run them" from Brendan Jackman fixes a pile of unrelated issues which Brendan encountered while runnimg our selftests. - The 2 patch series "fs/proc/task_mmu: add guard region bit to pagemap" from Lorenzo Stoakes permits userspace to use /proc/pid/pagemap to determine whether a particular page is a guard page. - The 7 patch series "mm, swap: remove swap slot cache" from Kairui Song removes the swap slot cache from the allocation path - it simply wasn't being effective. - The 5 patch series "mm: cleanups for device-exclusive entries (hmm)" from David Hildenbrand implements a number of unrelated cleanups in this code. - The 5 patch series "mm: Rework generic PTDUMP configs" from Anshuman Khandual implements a number of preparatoty cleanups to the GENERIC_PTDUMP Kconfig logic. - The 8 patch series "mm/damon: auto-tune aggregation interval" from SeongJae Park implements a feedback-driven automatic tuning feature for DAMON's aggregation interval tuning. - The 5 patch series "Fix lazy mmu mode" from Ryan Roberts fixes some issues in powerpc, sparc and x86 lazy MMU implementations.

This has caused a small amount of fallout - two or three issues were reported. In all cases the calling code was found to be incorrect. - The series "Some cleanup for memcg" from Chen Ridong implements some relatively monir cleanups for the memcontrol code. - The series "mm: fixes for device-exclusive entries (hmm)" from David Hildenbrand fixes a boatload of issues which David found then using device-exclusive PTE entries when THP is enabled. More work is needed, but this makes thins better - our own HMM selftests now succeed. - The series "mm: zswap: remove z3fold and zbud" from Yosry Ahmed remove the z3fold and zbud implementations. They have been deprecated for half a year and nobody has complained. - The series "mm: further simplify VMA merge operation" from Lorenzo Stoakes implements numerous simplifications in this area. No runtime effects are anticipated. - The series "mm/madvise: remove redundant mmap_lock operations from process_madvise()" from SeongJae Park rationalizes the locking in the madvise() implementation.

Our reasons for pulling it out were largely bogus and that change made the code more messy. This patchset provides small (0-10%) improvements on one microbenchmark. - The series "Docs/mm/damon: misc DAMOS filters documentation fixes and improves" from SeongJae Park does some maintenance work on the DAMON docs. - The series "hugetlb/CMA improvements for large systems" from Frank van der Linden addresses a pile of issues which have been observed when using CMA on large machines. - The series "mm/damon: introduce DAMOS filter type for unmapped pages" from SeongJae Park enables users of DMAON/DAMOS to filter my the page's mapped/unmapped status. - The series "zsmalloc/zram: there be preemption" from Sergey Senozhatsky teaches zram to run its compression and decompression operations preemptibly. - The series "selftests/mm: Some cleanups from trying to run them" from Brendan Jackman fixes a pile of unrelated issues which Brendan encountered while runnimg our selftests. - The series "fs/proc/task_mmu: add guard region bit to pagemap" from Lorenzo Stoakes permits userspace to use /proc/pid/pagemap to determine whether a particular page is a guard page. - The series "mm, swap: remove swap slot cache" from Kairui Song removes the swap slot cache from the allocation path - it simply wasn't being effective. - The series "mm: cleanups for device-exclusive entries (hmm)" from David Hildenbrand implements a number of unrelated cleanups in this code. - The series "mm: Rework generic PTDUMP configs" from Anshuman Khandual implements a number of preparatoty cleanups to the GENERIC_PTDUMP Kconfig logic. - The series "mm/damon: auto-tune aggregation interval" from SeongJae Park implements a feedback-driven automatic tuning feature for DAMON's aggregation interval tuning. - The series "Fix lazy mmu mode" from Ryan Roberts fixes some issues in powerpc, sparc and x86 lazy MMU implementations.

Merge tag 'pci-v6.15-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci
Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Enable Configuration RRS SV, which makes device readiness visible,
early instead of during child bus scanning (Bjorn Helgaas)
- Log debug messages about reset methods being used (Bjorn Helgaas)

Resource management:
- Enlarge devres table[] to accommodate bridge windows, ROM, IOV
BARs, etc., and validate BAR index in devres interfaces (Philipp
Stanner)
- Fix typo that repeatedly distributed resources to a bridge instead
of iterating over subordinate bridges, which resulted in too little
space to assign some BARs (Kai-Heng Feng)
- Relax bridge window tail sizing for optional resources, e.g., IOV
BARs, to avoid failures when removing and re-adding devices (Ilpo
Järvinen)
- Allow drivers to enable devices even if we haven't assigned
optional IOV resources to them (Ilpo Järvinen)
- Rework handling of optional resources (IOV BARs, ROMs) to reduce
failures if we can't allocate them (Ilpo Järvinen)
- Fix a NULL dereference in the SR-IOV VF creation error path (Shay
Drory)

Power management:
- Allow PCI bridges to go to D3Hot when suspending on all non-x86
systems (Manivannan Sadhasivam)
Power control:
- Create pwrctrl devices in pci_scan_device() to make it more
symmetric with pci_pwrctrl_unregister() and make pwrctrl devices
for PCI bridges possible (Manivannan Sadhasivam)
- Unregister pwrctrl devices in pci_destroy_dev() so DOE, ASPM, etc.
can still access devices after pci_stop_dev() (Manivannan
Sadhasivam)
- If there's a pwrctrl device for a PCI device, skip scanning it
because the pwrctrl core will rescan the bus after the device is
powered on (Manivannan Sadhasivam)
- Add a pwrctrl driver for PCI slots based on voltage regulators
described via devicetree (Manivannan Sadhasivam)
Bandwidth control:
- Add set_pcie_speed.sh to TEST_PROGS to fix issue when executing the
set_pcie_cooling_state.sh test case (Yi Lai)

assign for a bridge secondary bus (Lukas Wunner)
Hotplug:
- Drop superfluous pci_hotplug_slot_list, try_module_get() calls, and

(Ilpo Järvinen)
- Drop 'shpchp_debug' module parameter in favor of standard dynamic
debugging (Ilpo Järvinen)
- Drop unused cpcihp .get_power(), .set_power() function pointers

- Disable hotplug interrupts in portdrv only when pciehp is not
enabled to avoid issuing two hotplug commands too close together
(Feng Tang)

to address a deadlock when resuming after a device was removed
during system sleep (Lukas Wunner)
- Don't enable pciehp hotplug interupt when resuming in poll mode
(Ilpo Järvinen)
Virtualization:
- Fix bugs in 'pci=config_acs=' kernel command line parameter (Tushar
Dave)
DOE:
- Expose supported DOE features via sysfs (Alistair Francis)
- Allow DOE support to be enabled even if CXL isn't enabled (Alistair
Francis)
Endpoint framework:
- Convert PCI device data so pci-epf-test works correctly on
big-endian endpoint systems (Niklas Cassel)
- Add BAR_RESIZABLE type to endpoint framework and add DWC core
support for EPF drivers to set BAR_RESIZABLE type and size (Niklas
Cassel)
- Fix pci-epf-test double free that causes an oops if the host
reboots and PERST# deassertion restarts endpoint BAR allocation
(Christian Bruel)
- Fix endpoint BAR testing so tests can skip disabled BARs instead of
reporting them as failures (Niklas Cassel)

- Apply link speed restriction before bringing link up, not after
(Jim Quinlan)
- Update Max Link Speed in Link Capabilities via the internal
writable register, not the read-only config register (Jim Quinlan)
- Handle regulator_bulk_get() error to avoid panic when we call
regulator_bulk_free() later (Jim Quinlan)
- Disable regulators only when removing the bus immediately below a
Root Port because we don't support regulators deeper in the
hierarchy (Jim Quinlan)

- Correct MSG TLP generation so endpoints can generate INTx messages
(Hans Zhang)

Merge tag 'drm-next-2025-03-28' of https://gitlab.freedesktop.org/drm/kernel
Pull drm updates from Dave Airlie:
"Outside of drm there are some rust patches from Danilo who maintains
that area in here, and some pieces for drm header check tests.
The major things in here are a new driver supporting the touchbar
displays on M1/M2, the nova-core stub driver which is just the vehicle
for adding rust abstractions and start developing a real driver inside
of.
xe adds support for SVM with a non-driver specific SVM core
abstraction that will hopefully be useful for other drivers, along
with support for shrinking for TTM devices. I'm sure xe and AMD
support new devices, but the pipeline depth on these things is hard to
know what they end up being in the marketplace!

f2fs-for-6.15-rc1
In this round, there are three major updates: 1) folio conversion, 2) refactor for mount API conversion, 3) some performance improvement such as direct IO, checkpoint speed, and IO priority hints. For stability, there are patches which add more sanity checks and fixes some major issues like i_size in atomic write operations and write pointer recovery in zoned devices.

- Add infrastructure support to EDAC in order to be able to register memory

PCI/DOE: Expose DOE features via sysfs
PCIe r6.0 added support for Data Object Exchange (DOE). When DOE is supported, the DOE Discovery Feature must be implemented per PCIe r6.1, sec 6.30.1.1. DOE allows a requester to obtain information about the other DOE features supported by the device. The kernel already queries the DOE features supported and caches the values. Expose the values in sysfs to allow user space to determine which DOE features are supported by the PCIe device. By exposing the information to userspace, tools like lspci can relay the information to users. By listing all of the supported features we can allow userspace to parse the list, which might include vendor specific features as well as yet to be supported features. As the DOE Discovery feature must always be supported we treat it as a special named attribute case. This allows the usual PCI attribute_group handling to correctly create the doe_features directory when registering pci_doe_sysfs_group (otherwise it doesn't and sysfs_add_file_to_group() will seg fault). After this patch is supported you can see something like this when attaching a DOE device: $ ls /sys/devices/pci0000:00/0000:00:02.0//doe* 0001:01 0001:02 doe_discovery Link: https://lore.kernel.org/r/20250306075211.1855177-3-alistair@alistair23.me Signed-off-by: Alistair Francis <alistair@alistair23.me> [bhelgaas: drop pci_doe_sysfs_init() stub return, make DEVICE_ATTR_RO(doe_discovery) static] Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Reviewed-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> |

reboot: add support for configuring emergency hardware protection action
We currently leave the decision of whether to shutdown or reboot to protect hardware in an emergency situation to the individual drivers. This works out in some cases, where the driver detecting the critical failure has inside knowledge: It binds to the system management controller for example or is guided by hardware description that defines what to do. In the general case, however, the driver detecting the issue can't know what the appropriate course of action is and shouldn't be dictating the policy of dealing with it. Therefore, add a global hw_protection toggle that allows the user to specify whether shutdown or reboot should be the default action when the driver doesn't set policy. This introduces no functional change yet as hw_protection_trigger() has no callers, but these will be added in subsequent commits.

mm/cma: export total and free number of pages for CMA areas
Patch series "hugetlb/CMA improvements for large systems", v5. On large systems, we observed some issues with hugetlb and CMA: 1) When specifying a large number of hugetlb boot pages (hugepages= on the commandline), the kernel may run out of memory before it even gets to HVO. For example, if you have a 3072G system, and want to use 3024 1G hugetlb pages for VMs, that should leave you plenty of space for the hypervisor, provided you have the hugetlb vmemmap optimization (HVO) enabled. However, since the vmemmap pages are always allocated first, and then later in boot freed, you will actually run yourself out of memory before you can do HVO. This means not getting all the hugetlb pages you want, and worse, failure to boot if there is an allocation failure in the system from which it can't recover. 2) There is a system setup where you might want to use hugetlb_cma with a large value (say, again, 3024 out of 3072G like above), and then lower that if system usage allows it, to make room for non-hugetlb processes. For this, a variation of the problem above applies: the kernel runs out of unmovable space to allocate from before you finish boot, since your CMA area takes up all the space. 3) CMA wants to use one big contiguous area for allocations. Which fails if you have the aforementioned 3T system with a gap in the middle of physical memory (like the < 40bits BIOS DMA area seen on some AMD systems). You then won't be able to set up a CMA area for one of the NUMA nodes, leading to loss of half of your hugetlb CMA area. 4) Under the scenario mentioned in 2), when trying to grow the number of hugetlb pages after dropping it for a while, new CMA allocations may fail occasionally. This is not unexpected, some transient references on pages may prevent cma_alloc from succeeding under memory pressure. However, the hugetlb code then falls back to a normal contiguous alloc, which may end up succeeding. This is not always desired behavior. If you have a large CMA area, then the kernel has a restricted amount of memory it can do unmovable allocations from (a well known issue). A normal contiguous alloc may eat further in to this space. To resolve these issues, do the following: * Add hooks to the section init code to do custom initialization of memmap pages. Hugetlb bootmem (memblock) allocated pages can then be pre-HVOed. This avoids allocating a large number of vmemmap pages early in boot, only to have them be freed again later, and also avoids running out of memory as described under 1). Using these hooks for hugetlb is optional. It requires moving hugetlb bootmem allocation to an earlier spot by the architecture. This has been enabled on x86. * hugetlb_cma doesn't care about the CMA area it uses being one large contiguous range. Multiple smaller ranges are fine. The only requirements are that the areas should be on one NUMA node, and individual gigantic pages should be allocatable from them. So, implement multi-range support for CMA, avoiding issue 3). * Introduce a hugetlb_cma_only option on the commandline. This only allows allocations from CMA for gigantic pages, if hugetlb_cma= is also specified. * With hugetlb_cma_only active, it also makes sense to be able to pre-allocate gigantic hugetlb pages at boot time from the CMA area(s). Add a rudimentary early CMA allocation interface, that just grabs a piece of memblock-allocated space from the CMA area, which gets marked as allocated in the CMA bitmap when the CMA area is initialized. With this, hugepages= can be supported with hugetlb_cma=, making scenario 2) work. Additionally, fix some minor bugs, with one worth mentioning: since hugetlb gigantic bootmem pages are allocated by memblock, they may span multiple zones, as memblock doesn't (and mostly can't) know about zones. This can cause problems. A hugetlb page spanning multiple zones is bad, and it's worse with HVO, when the de-HVO step effectively sneakily re-assigns pages to a different zone than originally configured, since the tail pages all inherit the zone from the first 60 tail pages. This condition is not common, but can be easily reproduced using ZONE_MOVABLE. To fix this, add checks to see if gigantic bootmem pages intersect with multiple zones, and do not use them if they do, giving them back to the page allocator instead. The first patch is kind of along for the ride, except that maintaining an available_count for a CMA area is convenient for the multiple range support. This patch (of 27): In addition to the number of allocations and releases, system management software may like to be aware of the size of CMA areas, and how many pages are available in it. This information is currently not available, so export it in total_page and available_pages, respectively. The name 'available_pages' was picked over 'free_pages' because 'free' implies that the pages are unused. But they might not be, they just haven't been used by cma_alloc The number of available pages is tracked regardless of CONFIG_CMA_SYSFS, allowing for a few minor shortcuts in the code, avoiding bitmap operations.

IIO: New device support, features and cleanup for the 6.15 cycle.
The usual mixture of new drivers, support in existing drivers for new devices, a range of features and general subsystem cleanup. Two merges of immutable branches in here: * SPI offload support. Culmination of a long effort to bring the ability to offload triggered sequences of SPI operations to specific hardware, allow high datarate acquisition over an SPI bus (if you have the right hardware / FPGA firmware) * GPIO set-array-helper - enables code simplification. New device support ================== adi,ad3552r-hs: - Add support for AD3541r and AD3542r via newly supported FPGA HDL. adi,ad4030 - New driver supporting the AD4030, AD4630 AD4630-16, AD4640-24, AD4632-16, AD4632-24 1 and 2 channel high precision SPI ADCs. adi,ad4851 - New driver and backend support for the AD4851, AD4852, AD4853, AD4854, AD4855, AD4846, AD4857, AD4858 and AD4858I high speed multichannel simultaneous sampling ADCs. adi,ad7191 - New driver for this 24-bit ADC for precision bridge applications, adi,ad7380 - Add support for the adaq4381-4 which is a 14-bit version of the already supported adaq4380-1 adi,adis16550 - New driver using the ADIS library (which needed extensions) for this IMU. brcm,apds9160 - New driver for this proximity and ambient light sensor. dynaimage,al3000a - New driver for this illuminance sensor. mcube,mc3230 - Add support for the mc3510c accelerometer with a different scale to existing supported parts (some rework preceded this) nxp,imx93 - Add compatibles for imx94 and imx95 which are fully compatible with imx93. rockchip,saradc - Add support for the RK3528 ADC - Add support for the RK3562 ADC silab,si7210 - New driver to support this I2C Hall effect magnetic position sensor. ti,ads7138 - New driver supporting the ADS7128 and AD7138 I2C ADCs. Staging driver drop =================== adi,adis16240 - Drop this impact sensor. Interesting part but complex hence never left staging due to ABI challenges. No longer readily available so drop driver. New features ============ Documentation - A really nice overview document introduce ADC terminology and how it maps to IIO. core - New description for FAULT events, used in the ad7173. - filter_type ABI used in ad4130. buffer-dmaengine - Split DMA channel request from buffer allocation (for SPI offload) - Add a new _with_handle setup variant. (for SPI offload) adi,adf4371 - Add control of reference clock type and support for frequency doubling where appropriate. adi,ad4695 - Support SPI offload. - Support oversampling control. adi,ad5791 - Support SPI offload. adi,ad7124 - Add channel calibration support. adi,ad7380: - Alert support (threshold interrupts) - SPI offload support. adi,ad7606 - Support writing registers when using backend enabling software control of modes. adi,ad7944 - Support SPI offload. adi,ad9832 - Use devm_regulator_get_enable() to simplify code. adi,ad9834 - Use devm_regulator_get_enable() to simplify code. adi,adxl345 - Improve IRQ handling code. - Add debug access to registers. bosch,bmi270 - Add temperature channel support. - Add data ready trigger. google,cross_ec - Add trace events. mcube,mc3230 - Add mount matrix support - Add an OF match table. Cleanup and minor bug fixes =========================== Tree wide: - Stop using iio_device_claim_direct_scoped() and introduce sparse friendly iio_device_claim/release_direct() The conditional scoped cleanup has proved hard to deal with, requiring workarounds for various compiler issues and in is rather non-intuitive so abandon that experiment. One of the attractions of that approach was that it made it much harder to have unbalanced claim/release bugs so instead introduce a conditional-lock style boolean returning new pair of functions. These are inline in the header and have __acquire and __release calls allowing sparse to detect lack of balance. There are occasional false positives but so far those have reflected complex code paths that benefited from cleanup anyway. The first set of driver conversions are in this pull request, more to follow next cycle. Various related cleanup in drivers. Removal of the _scoped code is completed and the definition removed. - Use of str_enable_disable() and similar helpers. - Don't set regmap cache to REGCACHE_NONE as that's the default anyway. - Change some caches from RBTREE to MAPLE reflecting best practice. - Use the new gpiod_multi_set_value_cansleep() - Make sure to grab direct mode for some calibrations paths. - Avoid using memcmp on structures when checking for matching channel configs. Instead just match field by field. dt-bindings: - Fix up indentation inconsistencies. gts-helper: - Simplify building of available scale table. adi,ad-sigma-delta - Make sure to disable channel after calibration done. - Add error handling in configuring channel during calibration. adi,ad2s1201 - use a bitmap_write() rather than directly accessing underlying storage. adi,ad3552r-hs - Fix a wrong error message. - Make sure to use instruction mode for configuration. adi,ad4695 - Add a conversion to ensure exit from conversion mode. - Use custom regmap to handle required sclk rate change. - Fix an out of bounds array access - Simplify oversampling ratio handling. adi,ad4851 - Fix a sign bug. adi,ad5791 - Fix wrong exported number of storage bits. adi,ad7124 - Disable all channels at probe to avoid strange initial configurations. adi,ad7173 - Rework to allow static const struct ad_sigma_delta without need to make a copy. adi,ad7623 - Drop a BSD license tag that the authors consider unnecessary. adi,ad7768-1 - Fix channels sign description exposed to user space. - Set MOSI idle state to avoid accidental device reset. - Avoid some overkill locking. adi,axi-dac - Check if device interface is busy when enabling data stream. - Add control of bus mode. bosch,bmi270 - Move a struct definition to a c file as only used there. vishay,veml6030 - Enable regmap cache to reduce bus traffic. - Fix ABI bug around scale reporting. vishay,vem6075 - Check array bounds to harden against broken hardware.

f2fs: add carve_out sysfs node
For several zoned storage devices, vendors will provide extra space which was used for device level GC than specs and F2FS can use this space for filesystem level GC. To do that, we can reserve the space using reserved_blocks. However, it is not enough, since this extra space should not be shown to users. So, with this new sysfs node, we can hide the space by substracting reserved_blocks from total bytes.

HID: amd_sfh: Allow configuring whether HPD is enabled or disabled
Human presence detection (HPD) sensor uses a camera to determine when user is physically in front of the machine. This might not be a desirable behavior because it can (for example) cause the machine to wake on approach. Add a new sysfs file "hpd" that will control whether this sensor is enabled. Use the value of this sysfs file to turn off HPD and prevent it from re-enabling after resume from suspend.

EDAC: Update memory repair control interface for memory sparing feature
Update memory repair control interface for memory sparing feature. CXL memory devices can support soft and hard memory sparing at cacheline, row, bank and rank granularities. Memory sparing is defined as a repair function that replaces a portion of memory with a portion of functional memory at that same granularity. When a CXL device detects an error in memory, it will report to the host that there's need for a repair maintenance operation by using an event record where the "maintenance needed" flag is set. The event records contain the device physical address (DPA) and other attributes of the memory to repair such as bank group, bank, rank, row, column, channel etc. The kernel will report the corresponding CXL general media or DRAM trace event to userspace, and userspace tools (e.g. rasdaemon) will initiate a repair operation in response to the device request via the sysfs repair control.

EDAC: Add a memory repair control feature
Add a generic EDAC memory repair control driver to manage memory repairs in
the system, such as CXL Post Package Repair (PPR) and other soft and hard PPR
features.
For example, a CXL device with DRAM components that support PPR features may
implement PPR maintenance operations. DRAM components may support two types of
PPR:
- hard PPR, for a permanent row repair, and
- soft PPR, for a temporary row repair.
Soft PPR is much faster than hard PPR, but the repair is lost with a power
cycle.
When a CXL device detects an error in a memory, it may report the need for
a repair maintenance operation by using an event record where the "maintenance
needed" flag is set. The event records contain the device physical
address (DPA) and other optional attributes of the memory to repair.
The kernel will report the corresponding CXL general media or DRAM trace event
to userspace, and userspace tools (e.g. rasdaemon) will initiate a repair
operation in response to the device request via the sysfs repair control.
Device with memory repair features registers with EDAC device driver, which
retrieves a memory repair descriptor from EDAC memory repair driver and exposes
the sysfs repair control attributes to userspace in
/sys/bus/edac/devices/<dev-name>/mem_repairX/.
The common memory repair control interface abstracts the control of arbitrary
memory repair functionality into a standardized set of functions. The sysfs
memory repair attribute nodes are only available if the client driver has
implemented the corresponding attribute callback function and provided
operations to the EDAC device driver during registration.

EDAC: Add a Error Check Scrub control feature
Add an Error Check Scrub (ECS) control to manage a memory device's ECS feature. The ECS is a feature defined in JEDEC DDR5 SDRAM Specification (JESD79-5) and allows the DRAM to internally read, correct single-bit errors, and write back corrected data bits to the DRAM array while providing transparency to error counts. The DDR5 device contains a number of memory media Field Replaceable Units (FRU) per device. The DDR5 ECS feature and thus the ECS control driver supports configuring the ECS parameters per FRU. Memory devices support the ECS feature register with the EDAC device driver, which retrieves the ECS descriptor from the EDAC ECS driver. This driver exposes sysfs ECS control attributes to userspace via /sys/bus/edac/devices/<dev-name>/ecs_fruX/. The common sysfs ECS control interface abstracts the control of an arbitrary ECS functionality to a common set of functions. Support for the ECS feature is added separately because the control attributes of the DDR5 ECS feature differ from those of the scrub feature. The sysfs ECS attribute nodes are only present if the client driver has implemented the corresponding attribute callback function and passed the necessary operations to the EDAC RAS feature driver during registration.

However, the gear speed is only toggled between min and max during clock scaling. Enable multi-level gear scaling by mapping clock frequencies to gear speeds, so that when devfreq scales clock frequencies we can put the UFS link at the appropraite gear speeds accordingly.

f2fs: add a sysfs entry to reclaim POSIX_FADV_NOREUSE pages
1. fadvise(fd1, POSIX_FADV_NOREUSE, {0,3});
2. fadvise(fd2, POSIX_FADV_NOREUSE, {1,2});
3. fadvise(fd3, POSIX_FADV_NOREUSE, {3,1});
4. echo 1024 > /sys/fs/f2fs/tuning/reclaim_caches_kb
This gives a way to reclaim file-backed pages by iterating all f2fs mounts until
reclaiming 1MB page cache ranges, registered by #1, #2, and #3.
5. cat /sys/fs/f2fs/tuning/reclaim_caches_kb

scsi: ufs: core: Critical health condition
Martin hi, The UFS4.1 standard, released on January 8, 2025, added a new exception event: HEALTH_CRITICAL, which notifies the host of a device's critical health condition. This notification implies that the device is approaching the end of its lifetime based on the amount of performed program/erase cycles. Once an EOL (End-of-Life) exception event is received, we increment a designated member, which is exposed via a sysfs entry. This new entry, will report the number of times a critical health event has been reported by a UFS device. To handle this new sysfs entry, userspace applications can use select(), poll(), or epoll() to monitor changes in the critical_health attribute. The kernel will call sysfs_notify() to signal changes, allowing the userspace application to detect and respond to these changes efficiently. The host can gain further insight into the specific issue by reading one of the following attributes: bPreEOLInfo, bDeviceLifeTimeEstA, bDeviceLifeTimeEstB, bWriteBoosterBufferLifeTimeEst, and bRPMBLifeTimeEst. All those are available for reading via the driver's sysfs entries or through an applicable utility. It is up to userspace to read these attributes if needed.
