git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull runtime verification updates from Steven Rostedt:
- Refactor da_monitor header to share handlers across monitor types
No functional changes, only less code duplication.
- Add Hybrid Automata model class
Add a new model class that extends deterministic automata by adding
constraints on transitions and states. Those constraints can take
into account wall-clock time and as such allow RV monitor to make
assertions on real time. Add documentation and code generation
scripts.
- Add stall monitor as hybrid automaton example
Add a monitor that triggers a violation when a task is stalling as an
example of automaton working with real time variables.
- Convert the opid monitor to a hybrid automaton
The opid monitor can be heavily simplified if written as a hybrid
automaton: instead of tracking preempt and interrupt enable/disable
events, it can just run constraints on the preemption/interrupt
states when events like wakeup and need_resched verify.
- Add support for per-object monitors in DA/HA
Allow writing deterministic and hybrid automata monitors for generic
objects (e.g. any struct), by exploiting a hash table where objects
are saved. This allows to track more than just tasks in RV. For
instance it will be used to track deadline entities in deadline
monitors.
- Add deadline tracepoints and move some deadline utilities
Prepare the ground for deadline monitors by defining events and
exporting helpers.
- Add nomiss deadline monitor
Add first example of deadline monitor asserting all entities complete
before their deadline.
- Improve rvgen error handling
Introduce AutomataError exception class and better handle expected
exceptions while showing a backtrace for unexpected ones.
- Improve python code quality in rvgen
Refactor the rvgen generation scripts to align with python best
practices: use f-strings instead of %, use len() instead of
__len__(), remove semicolons, use context managers for file
operations, fix whitespace violations, extract magic strings into
constants, remove unused imports and methods.
- Fix small bugs in rvgen
The generator scripts presented some corner case bugs: logical error
in validating what a correct dot file looks like, fix an isinstance()
check, enforce a dot file has an initial state, fix type annotations
and typos in comments.
- rvgen refactoring
Refactor automata.py to use iterator-based parsing and handle
required arguments directly in argparse.
- Allow epoll in rtapp-sleep monitor
The epoll_wait call is now rt-friendly so it should be allowed in the
sleep monitor as a valid sleep method.
* tag 'trace-rv-v7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: (32 commits)

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull ring-buffer updates from Steven Rostedt:
- Add remote buffers for pKVM
pKVM has a hypervisor component that is used to protect the guest
from the host kernel. This hypervisor is a black box to the kernel as
the kernel is to user space. The remote buffers are used to have a
memory mapping between the hypervisor and the kernel where kernel may
send commands to enable tracing within the hypervisor. Then the
kernel will read this memory mapping just like user space can read
the memory mapped ring buffer of the kernel tracing system.
Since the hypervisor only has a single context, it doesn't need to
worry about races between normal context, interrupt context and NMIs
like the kernel does. The ring buffer it uses doesn't need to be as
complex. The remote buffers are a simple version of the ring buffer
that works in a single context. They are still per-CPU and use sub
buffers. The data layout is the same as the kernel's ring buffer to
share the same parsing.
Currently, only ARM64 implements pKVM, but there's work to implement
it also in x86. The remote buffer code is separated out from the ARM
implementation so that it can be used in the future by x86.
The ARM64 updates for pKVM is in the ARM/KVM tree and it merged in
the remote buffers of this tree.
- Make the backup instance non reusable
The backup instance is a copy of the persistent ring buffer so that
the persistent ring buffer could start recording again without using
the data from the previous boot. The backup isn't for normal tracing.
It is made read-only, and after it is consumed, it is automatically
removed.
- Have backup copy persistent instance before it starts recording
To allow the persistent ring buffer to start recording from the
kernel command line commands, move the copy of the backup instance to
before the the command line options start recording.
- Report header_page overwrite field as "char" and not "int'
The rust parser of the header_page file was triggering a warning when
it defined the overwrite variable as "int" but it was only a single
byte in size.
- Fix memory barriers for the trace_buffer CPU mask
When a CPU comes online, the bit is set to allow readers to know that
the CPU buffer is allocated. The bit is set after the allocation is
done, and a smp_wmb() is performed after the allocation and before
the setting of the bit. But instead of adding a smp_rmb() to all
readers, since once a buffer is created for a CPU it is not deleted
if that CPU goes offline, so this allocation is almost always done at
boot up before any readers exist.
If for the unlikely case where a CPU comes online for the first time
after the system boot has finished, send an IPI to all CPUs to force
the smp_rmb() for each CPU.
- Show clock function being used in debugging ring buffer data
When the ring buffer checks are enabled and the ring buffer detects
an inconsistency in the times of the invents, print out the clock
being used when the error occurred. There was a very hard to hit bug
that would happen every so often and it ended up being only triggered
when the jiffies clock was being used. If the bug showed the clock
being used, it would have been much easier to find the problem (which
was an internal function was being traced which caused the clock
accounting to go off).

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Allow TLP Processing Hints to be enabled for RCiEPs (George Abraham
P)
- Enable AtomicOps only if we know the Root Port supports them (Gerd
Bayer)
- Don't enable AtomicOps for RCiEPs since none of them need Atomic
Ops and we can't tell whether the Root Complex would support them
(Gerd Bayer)
- Leave Precision Time Measurement disabled until a driver enables it
to avoid PCIe errors (Mika Westerberg)
- Make pci_set_vga_state() fail if bridge doesn't support VGA
routing, i.e., PCI_BRIDGE_CTL_VGA is not writable, and return
errors to vga_get() callers including userspace via
/dev/vga_arbiter (Simon Richter)
- Validate max-link-speed from DT in j721e, brcmstb, mediatek-gen3,
rzg3s drivers (where the actual controller constraints are known),
and remove validation from the generic OF DT accessor (Hans Zhang)
- Remove pc110pad driver (no longer useful after 486 CPU support
removed) and no_pci_devices() (pc110pad was the last user) (Dmitry
Torokhov, Heiner Kallweit)
Resource management:
- Prevent assigning space to unimplemented bridge windows; previously
we mistakenly assumed prefetchable window existed and assigned
space and put a BAR there (Ahmed Naseef)
- Avoid shrinking bridge windows to fit in the initial Root Port
window; fixes one problem with devices with large BARs connected
via switches, e.g., Thunderbolt (Ilpo Järvinen)
- Pass full extent of empty space, not just the aligned space, to
resource_alignf callback so free space before the requested
alignment can be used (Ilpo Järvinen)
- Place small resources before larger ones for better utilization of
address space (Ilpo Järvinen)
- Fix alignment calculation for resource size larger than align,
e.g., bridge windows larger than the 1MB required alignment (Ilpo
Järvinen)
Reset:
- Update slot handling so all ARI functions are treated as being in
the same slot. They're all reset by Secondary Bus Reset, but
previously drivers of ARI functions that appeared to be on a
non-zero device weren't notified and fatal hardware errors could
result (Keith Busch)
- Make sysfs reset_subordinate hotplug safe to avoid spurious hotplug
events (Keith Busch)
- Hide Secondary Bus Reset ('bus') from sysfs reset_methods if masked
by CXL because it has no effect (Vidya Sagar)
- Avoid FLR for AMD NPU device, where it causes the device to hang
(Lizhi Hou)
Error handling:
- Clear only error bits in PCIe Device Status to avoid accidentally
clearing Emergency Power Reduction Detected (Shuai Xue)
- Check for AER errors even in devices without drivers (Lukas Wunner)
- Initialize ratelimit info so DPC and EDR paths log AER error
information (Kuppuswamy Sathyanarayanan)
Power control:
- Add UPD720201/UPD720202 USB 3.0 xHCI Host Controller .compatible so
generic pwrctrl driver can control it (Neil Armstrong)
Hotplug:
- Set LED_HW_PLUGGABLE for NPEM hotplug-capable ports so LED core
doesn't complain when setting brightness fails because the endpoint
is gone (Richard Cheng)
Peer-to-peer DMA:
- Allow wildcards in list of host bridges that support peer-to-peer
DMA between hierarchy domains and add all Google SoCs (Jacob
Moroni)
Endpoint framework:
- Advertise dynamic inbound mapping support in pci-epf-test and
update host pci_endpoint_test to skip doorbell testing if not
advertised by endpoint (Koichiro Den)
- Return 0, not remaining timeout, when MHI eDMA ops complete so
mhi_ep_ring_add_element() doesn't interpret non-zero as failure
(Daniel Hodges)
- Remove vntb and ntb duplicate resource teardown that leads to oops
when .allow_link() fails or .drop_link() is called (Koichiro Den)
- Disable vntb delayed work before clearing BAR mappings and
doorbells to avoid oops caused by doing the work after resources
have been torn down (Koichiro Den)
- Add a way to describe reserved subregions within BARs, e.g.,
platform-owned fixed register windows, and use it for the RK3588
BAR4 DMA ctrl window (Koichiro Den)
- Add BAR_DISABLED for BARs that will never be available to an EPF
driver, and change some BAR_RESERVED annotations to BAR_DISABLED
(Niklas Cassel)
- Add NTB .get_dma_dev() callback for cases where DMA API requires a
different device, e.g., vNTB devices (Koichiro Den)
- Add reserved region types for MSI-X Table and PBA so Endpoint
controllers can them as describe hardware-owned regions in a
BAR_RESERVED BAR (Manikanta Maddireddy)
- Make Tegra194/234 BAR0 programmable and remove 1MB size limit
(Manikanta Maddireddy)
- Expose Tegra BAR2 (MSI-X) and BAR4 (DMA) as 64-bit BAR_RESERVED
(Manikanta Maddireddy)
- Add Tegra194 and Tegra234 device table entries to pci_endpoint_test
(Manikanta Maddireddy)
- Skip the BAR subrange selftest if there are not enough inbound
window resources to run the test (Christian Bruel)
New native PCIe controller drivers:
- Add DT binding and driver for Andes QiLai SoC PCIe host controller
(Randolph Lin)
- Add DT binding and driver for ESWIN PCIe Root Complex (Senchuan
Zhang)
Baikal T-1 PCIe controller driver:
- Remove driver since it never quite became usable (Andy Shevchenko)
Cadence PCIe controller driver:
- Implement byte/word config reads with dword (32-bit) reads because
some Cadence controllers don't support sub-dword accesses (Aksh
Garg)
CIX Sky1 PCIe controller driver:
- Add 'power-domains' to DT binding for SCMI power domain (Gary Yang)
Freescale i.MX6 PCIe controller driver:
- Add i.MX94 and i.MX943 to fsl,imx6q-pcie-ep DT binding (Richard
Zhu)

git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext
Pull sched_ext updates from Tejun Heo:
- cgroup sub-scheduler groundwork
Multiple BPF schedulers can be attached to cgroups and the dispatch
path is made hierarchical. This involves substantial restructuring of
the core dispatch, bypass, watchdog, and dump paths to be
per-scheduler, along with new infrastructure for scheduler ownership
enforcement, lifecycle management, and cgroup subtree iteration
The enqueue path is not yet updated and will follow in a later cycle
- scx_bpf_dsq_reenq() generalized to support any DSQ including remote
local DSQs and user DSQs
Built on top of this, SCX_ENQ_IMMED guarantees that tasks dispatched
to local DSQs either run immediately or get reenqueued back through
ops.enqueue(), giving schedulers tighter control over queueing
latency
Also useful for opportunistic CPU sharing across sub-schedulers
- ops.dequeue() was only invoked when the core knew a task was in BPF
data structures, missing scheduling property change events and
skipping callbacks for non-local DSQ dispatches from ops.select_cpu()
Fixed to guarantee exactly one ops.dequeue() call when a task leaves
BPF scheduler custody
- Kfunc access validation moved from runtime to BPF verifier time,
removing runtime mask enforcement
- Idle SMT sibling prioritization in the idle CPU selection path
- Documentation, selftest, and tooling updates. Misc bug fixes and
cleanups

Commit c43267e6794a ("Merge tag 'arm64-upstream' of git://...") had a
conflict in the irq entry/exit code due to commit c5538d0141b3 ("entry:
Split kernel mode logic from irqentry_{enter,exit}()") having moved the
core code in irqentry_enter/exit() from kernel/entry/common.c into
helper inline functions in include/linux/irq-entry-common.h.
On the other side of the merge, the timer-core code had introduced
deferred hrtimer rearming infrastructure in commit 0e98eb14814e ("entry:
Prepare for deferred hrtimer rearming"), adding two calls to
hrtimer_rearm_deferred() in irqentry_enter().
When merging the two, moving the two calls to the new location wasn't a
problem, but afterwards I had made the mistake of looking what had
happened in linux-next. And linux-next had a very different merge
resolution in commit 04f02dc3ea74 ("Merge tag 'entry-for-arm64-26-04-08'
into sched/hrtick"), which had unified the two calls into one single
call-site in irqentry_exit_to_kernel_mode_preempt().
And that merge resolution looked cleverer than the straightforward one I
had done, so I re-did my merge the way it had been done in linux-next.
But it turns out nobody apparently tests linux-next, and the merge in
linux-next was just wrong.
The difference is that hrtimer_rearm_deferred() doesn't get called at
all for the case when state.exit_rcu is true, and the boot will
typically fail due to timers not triggering correctly.
So this undoes the "clever" merge, and does the straightforward one
instead.

git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull vfs mount updates from Christian Brauner:
- Add FSMOUNT_NAMESPACE flag to fsmount() that creates a new mount
namespace with the newly created filesystem attached to a copy of the
real rootfs. This returns a namespace file descriptor instead of an
O_PATH mount fd, similar to how OPEN_TREE_NAMESPACE works for
open_tree().
This allows creating a new filesystem and immediately placing it in a
new mount namespace in a single operation, which is useful for
container runtimes and other namespace-based isolation mechanisms.
This accompanies OPEN_TREE_NAMESPACE and avoids a needless detour via
OPEN_TREE_NAMESPACE to get the same effect. Will be especially useful
when you mount an actual filesystem to be used as the container
rootfs.
- Currently, creating a new mount namespace always copies the entire
mount tree from the caller's namespace. For containers and sandboxes
that intend to build their mount table from scratch this is wasteful:
they inherit a potentially large mount tree only to immediately tear
it down.
This series adds support for creating a mount namespace that contains
only a clone of the root mount, with none of the child mounts. Two
new flags are introduced:
- CLONE_EMPTY_MNTNS (0x400000000) for clone3(), using the 64-bit flag space
- UNSHARE_EMPTY_MNTNS (0x00100000) for unshare()
Both flags imply CLONE_NEWNS. The resulting namespace contains a
single nullfs root mount with an immutable empty directory. The
intended workflow is to then mount a real filesystem (e.g., tmpfs)
over the root and build the mount table from there.
- Allow MOVE_MOUNT_BENEATH to target the caller's rootfs, allowing to
switch out the rootfs without pivot_root(2).
The traditional approach to switching the rootfs involves
pivot_root(2) or a chroot_fs_refs()-based mechanism that atomically
updates fs->root for all tasks sharing the same fs_struct. This has
consequences for fork(), unshare(CLONE_FS), and setns().
This series instead decomposes root-switching into individually
atomic, locally-scoped steps:
fd_tree = open_tree(-EBADF, "/newroot", OPEN_TREE_CLONE | OPEN_TREE_CLOEXEC);
fchdir(fd_tree);
move_mount(fd_tree, "", AT_FDCWD, "/", MOVE_MOUNT_BENEATH | MOVE_MOUNT_F_EMPTY_PATH);
chroot(".");
umount2(".", MNT_DETACH);
Since each step only modifies the caller's own state, the
fork/unshare/setns races are eliminated by design.
A key step to making this possible is to remove the locked mount
restriction. Originally MOVE_MOUNT_BENEATH doesn't support mounting
beneath a mount that is locked. The locked mount protects the
underlying mount from being revealed. This is a core mechanism of
unshare(CLONE_NEWUSER | CLONE_NEWNS). The mounts in the new mount
namespace become locked. That effectively makes the new mount table
useless as the caller cannot ever get rid of any of the mounts no
matter how useless they are.
We can lift this restriction though. We simply transfer the locked
property from the top mount to the mount beneath. This works because
what we care about is to protect the underlying mount aka the parent.
The mount mounted between the parent and the top mount takes over the
job of protecting the parent mount from the top mount mount. This
leaves us free to remove the locked property from the top mount which
can consequently be unmounted:
unshare(CLONE_NEWUSER | CLONE_NEWNS)
and we inherit a clone of procfs on /proc then currently we cannot
unmount it as:
umount -l /proc
will fail with EINVAL because the procfs mount is locked.
After this series we can now do:
mount --beneath -t tmpfs tmpfs /proc
umount -l /proc
after which a tmpfs mount has been placed beneath the procfs mount.
The tmpfs mount has become locked and the procfs mount has become
unlocked.
This means you can safely modify an inherited mount table after
unprivileged namespace creation.
Afterwards we simply make it possible to move a mount beneath the
rootfs allowing to upgrade the rootfs.
Removing the locked restriction makes this very useful for containers
created with unshare(CLONE_NEWUSER | CLONE_NEWNS) to reshuffle an
inherited mount table safely and MOVE_MOUNT_BENEATH makes it possible
to switch out the rootfs instead of using the costly pivot_root(2).

Pull module updates from Sami Tolvanen:
"Kernel symbol flags:
- Replace the separate *_gpl symbol sections (__ksymtab_gpl and
__kcrctab_gpl) with a unified symbol table and a new __kflagstab
section.
This section stores symbol flags, such as the GPL-only flag, as an
8-bit bitset for each exported symbol. This is a cleanup that
simplifies symbol lookup in the module loader by avoiding table
fragmentation and will allow a cleaner way to add more flags later
if needed.
Module signature UAPI:
- Move struct module_signature to the UAPI headers to allow reuse by
tools outside the kernel proper, such as kmod and
scripts/sign-file.
This also renames a few constants for clarity and drops unused
signature types as preparation for hash-based module integrity
checking work that's in progress.
Sysfs:
- Add a /sys/module/<module>/import_ns sysfs attribute to show the
symbol namespaces imported by loaded modules.
This makes it easier to verify driver API access at runtime on
systems that care about such things (e.g. Android).
Cleanups and fixes:
- Force sh_addr to 0 for all sections in module.lds. This prevents
non-zero section addresses when linking modules with 'ld.bfd -r',
which confused elfutils.
- Fix a memory leak of charp module parameters on module unload when
the kernel is configured with CONFIG_SYSFS=n.
- Override the -EEXIST error code returned by module_init() to
userspace. This prevents confusion with the errno reserved by the
module loader to indicate that a module is already loaded.
- Simplify the warning message and drop the stack dump on positive
returns from module_init().
- Drop unnecessary extern keywords from function declarations and
synchronize parse_args() arguments with their implementation"

"The biggest changes are MPAM enablement in drivers/resctrl and new PMU
support under drivers/perf.

Pull x86 SEV updates from Borislav Petkov:
- Change the SEV host code handling of when SNP gets enabled in order
to allow the machine to claim SNP-related resources only when SNP
guests are really going to be launched. The user requests this by
loading the ccp module and thus it controls when SNP initialization
is done
So export an API which module code can call and do the necessary SNP
setup only when really needed
- Drop an unnecessary write-back and invalidate operation that was
being performed too early, since the ccp driver already issues its
own at the correct point in the initialization sequence
- Drop the hotplug callbacks for enabling SNP on newly onlined CPUs,
which were both architecturally unsound (the firmware rejects
initialization if any CPU lacks the required configuration) and buggy
(the MFDM SYSCFG MSR bit was not being set)

Pull timer core updates from Thomas Gleixner:
- A rework of the hrtimer subsystem to reduce the overhead for
frequently armed timers, especially the hrtick scheduler timer:
- Better timer locality decision
- Simplification of the evaluation of the first expiry time by
keeping track of the neighbor timers in the RB-tree by providing
a RB-tree variant with neighbor links. That avoids walking the
RB-tree on removal to find the next expiry time, but even more
important allows to quickly evaluate whether a timer which is
rearmed changes the position in the RB-tree with the modified
expiry time or not. If not, the dequeue/enqueue sequence which
both can end up in rebalancing can be completely avoided.
- Deferred reprogramming of the underlying clock event device. This
optimizes for the situation where a hrtimer callback sets the
need resched bit. In that case the code attempts to defer the
re-programming of the clock event device up to the point where
the scheduler has picked the next task and has the next hrtick
timer armed. In case that there is no immediate reschedule or
soft interrupts have to be handled before reaching the reschedule
point in the interrupt entry code the clock event is reprogrammed
in one of those code paths to prevent that the timer becomes
stale.
- Support for clocksource coupled clockevents
The TSC deadline timer is coupled to the TSC. The next event is
programmed in TSC time. Currently this is done by converting the
CLOCK_MONOTONIC based expiry value into a relative timeout,
converting it into TSC ticks, reading the TSC adding the delta
ticks and writing the deadline MSR.
As the timekeeping core has the conversion factors for the TSC
already, the whole back and forth conversion can be completely
avoided. The timekeeping core calculates the reverse conversion
factors from nanoseconds to TSC ticks and utilizes the base
timestamps of TSC and CLOCK_MONOTONIC which are updated once per
tick. This allows a direct conversion into the TSC deadline value
without reading the time and as a bonus keeps the deadline
conversion in sync with the TSC conversion factors, which are
updated by adjtimex() on systems with NTP/PTP enabled.
- Allow inlining of the clocksource read and clockevent write
functions when they are tiny enough, e.g. on x86 RDTSC and WRMSR.
With all those enhancements in place a hrtick enabled scheduler
provides the same performance as without hrtick. But also other
hrtimer users obviously benefit from these optimizations.
- Robustness improvements and cleanups of historical sins in the
hrtimer and timekeeping code.
- Rewrite of the clocksource watchdog.
The clocksource watchdog code has over time reached the state of an
impenetrable maze of duct tape and staples. The original design,
which was made in the context of systems far smaller than today, is
based on the assumption that the to be monitored clocksource (TSC)
can be trivially compared against a known to be stable clocksource
(HPET/ACPI-PM timer).
Over the years this rather naive approach turned out to have major
flaws. Long delays between the watchdog invocations can cause wrap
arounds of the reference clocksource. The access to the reference
clocksource degrades on large multi-sockets systems dure to
interconnect congestion. This has been addressed with various
heuristics which degraded the accuracy of the watchdog to the point
that it fails to detect actual TSC problems on older hardware which
exposes slow inter CPU drifts due to firmware manipulating the TSC to
hide SMI time.
The rewrite addresses this by:
- Restricting the validation against the reference clocksource to
the boot CPU which is usually closest to the legacy block which
contains the reference clocksource (HPET/ACPI-PM).
- Do a round robin validation betwen the boot CPU and the other
CPUs based only on the TSC with an algorithm similar to the TSC
synchronization code during CPU hotplug.
- Being more leniant versus remote timeouts
- The usual tiny fixes, cleanups and enhancements all over the place

Pull gpio updates from Bartosz Golaszewski:
"For this merge window we have two new drivers: support for
GPIO-signalled ACPI events on Intel platforms and a generic
GPIO-over-pinctrl driver using the ARM SCMI protocol for
controlling pins.
Several things have been reworked in GPIO core: we unduplicated GPIO
hog handling, reduced the number of SRCU locks and dereferences,
improved support for software-node-based lookup and removed more
legacy code after converting remaining users to modern alternatives.
There's also a number of driver reworks and refactoring, documentation
updates, some bug-fixes and new tests.
GPIO core:
- defer probe on software node lookups when the remote software node
exists but has not been registered as a firmware node yet
- unify GPIO hog handling by moving code duplicated in OF and ACPI
modules into GPIO core and allow setting up hogs with software
nodes
- allow matching GPIO controllers by secondary firmware node if
matching by primary does not succeed
- demote deferral warnings to debug level as they are quite normal
when using software nodes which don't support fw_devlink yet
- disable the legacy GPIO character device uAPI v1 supprt in Kconfig
by default
- rework several core functions in preparation for the upcoming
Revocable helper library for protecting resources against sudden
removal, this reduces the number of SRCU dereferences in GPIO core
- simplify file descriptor logic in GPIO character device code by
using FD_PREPARE()
- introduce a header defining symbols used by both GPIO consumers and
providers to avoid having to include provider-specific headers from
drivers which only consume GPIOs
- replace snprintf() with strscpy() where formatting is not required
New drivers:
- add the gpio-by-pinctrl generic driver using the ARM SCMI protocol
to control GPIOs (along with SCMI changes pulled from the pinctrl
tree)
- add a driver providing support for handling of platform events via
GPIO-signalled ACPI events (used on Intel Nova Lake and later
platforms)
Driver changes:
- extend the gpio-kempld driver with support for more recent models,
interrupts and setting/getting multiple values at once
- improve interrupt handling in gpio-brcmstb
- add support for multi-SoC systems in gpio-tegra186
- make sure we return correct values from the .get() callbacks in
several GPIO drivers by normalizing any values other than 0, 1 or
negative error numbers
- use flexible arrays in several drivers to reduce the number of
required memory allocations
- simplify synchronous waiting for virtual drivers to probe and
remove the dedicated, a bit overengineered helper library
dev-sync-probe
- remove unneeded Kconfig dependencies on OF_GPIO in several drivers
and subsystems
- convert the two remaining users of of_get_named_gpio() to using
GPIO descriptors and remove the (no longer used) function along
with the header that declares it
- add missing includes in gpio-mmio
- shrink and simplify code in gpio-max732x by using guard(mutex)
- remove duplicated code handling the 'ngpios' property from
gpio-ts4800, it's already handled in GPIO core
- use correct variable type in gpio-aspeed
- add support for a new model in gpio-realtek-otto
- allow to specify the active-low setting of simulated hogs over the
configfs interface (in addition to existing devicetree support) in
gpio-sim
Bug fixes:
- clear the OF_POPULATED flag on hog nodes in GPIO chip remove path
on OF systems
- fix resource leaks in error path in gpiochip_add_data_with_key()
- drop redundant device reference in gpio-mpsse
Tests:
- add selftests for use-after-free cases in GPIO character device
code
DT bindings:
- add a DT binding document for SCMI based, gpio-over-pinctrl devices
- fix interrupt description in microchip,mpfs-gpio
- add new compatible for gpio-realtek-otto
- describe the resets of the mpfs-gpio controller
- fix maintainer's email in gpio-delay bindings
- remove the binding document for cavium,thunder-8890 as the
corresponding device is bound over PCI and not firmware nodes
Documentation:
- update the recommended way of converting legacy boards to using
software nodes for GPIO description
- describe GPIO line value semantics
- misc updates to kerneldocs
Misc:
- convert OMAP1 ams-delta board to using GPIO hogs described with
software nodes"

On the cpuidle front, a new C-states table for Intel Panther Lake is
added to the intel_idle driver, the stopped tick handling in the menu
and teo governors is updated, and there are a couple of cleanups.
Apart from the above, support for Tegra114 is added to devfreq and
there are assorted cleanups of that code, there are also two updates
of the operating performance points (OPP) library, two minor updates
related to hibernation, and cpupower utility man pages updates and
cleanups.
Specifics:
- Update qcom-hw DT bindings to include Eliza hardware (Abel Vesa)
- Update cpufreq-dt-platdev blocklist (Faruque Ansari)
- Minor updates to driver and dt-bindings for Tegra (Thierry Reding,
Rosen Penev)
- Add MAINTAINERS entry for CPPC driver (Viresh Kumar)
- Add support for new features: CPPC performance priority, Dynamic
EPP, Raw EPP, and new unit tests for them to amd-pstate (Gautham
Shenoy, Mario Limonciello)
- Fix sysfs files being present when HW missing and broken/outdated
documentation in the amd-pstate driver (Ninad Naik, Gautham Shenoy)
- Pass the policy to cpufreq_driver->adjust_perf() to avoid using
cpufreq_cpu_get() in the .adjust_perf() callback in amd-pstate
which leads to a scheduling-while-atomic bug (K Prateek Nayak)
- Clean up dead code in Kconfig for cpufreq (Julian Braha)
- Remove max_freq_req update for pre-existing cpufreq policy and add
a boost_freq_req QoS request to save the boost constraint instead
of overwriting the last scaling_max_freq constraint (Pierre
Gondois)
- Embed cpufreq QoS freq_req objects in cpufreq policy so they all
are allocated in one go along with the policy to simplify lifetime
rules and avoid error handling issues (Viresh Kumar)
- Use DMI max speed when CPPC is unavailable in the acpi-cpufreq
scaling driver (Henry Tseng)
- Switch policy_is_shared() in cpufreq to using cpumask_nth() instead
of cpumask_weight() because the former is more efficient (Yury
Norov)
- Use sysfs_emit() in sysfs show functions for cpufreq governor
attributes (Thorsten Blum)
- Update intel_pstate to stop returning an error when "off" is
written to its status sysfs attribute while the driver is already
off (Fabio De Francesco)
- Include current frequency in the debug message printed by
__cpufreq_driver_target() (Pengjie Zhang)
- Refine stopped tick handling in the menu cpuidle governor and
rearrange stopped tick handling in the teo cpuidle governor (Rafael
Wysocki)

OPP debugfs (Manivannan Sadhasivam)
- Fix scoped_guard in dev_pm_opp_xlate_required_opp() (Viresh Kumar)
- Return -ENODATA if the snapshot image is not loaded (Alberto
Garcia)
- Remove inclusion of crypto/hash.h from hibernate_64.c on x86 (Eric
Biggers)
- Clean up and rearrange the intel_rapl power capping driver to make
the respective interface drivers (TPMI, MSR, and MMOI) hold their
own settings and primitives and consolidate PL4 and PMU support
flags into rapl_defaults (Kuppuswamy Sathyanarayanan)
- Correct kernel-doc function parameter names in the power capping
core code (Randy Dunlap)
- Remove unneeded casting for HZ_PER_KHZ in devfreq (Andy Shevchenko)
- Use _visible attribute to replace create/remove_sysfs_files() in
devfreq (Pengjie Zhang)
- Add Tegra114 support to activity monitor device in tegra30-devfreq
as a preparation to upcoming EMC controller support (Svyatoslav
Ryhel)
- Fix mistakes in cpupower man pages, add the boost and epp options
to the cpupower-frequency-info man page, and add the perf-bias
option to the cpupower-info man page (Roberto Ricci)
- Remove unnecessary extern declarations from getopt.h in arguments
parsing functions in cpufreq-set, cpuidle-info, cpuidle-set,
cpupower-info, and cpupower-set utilities (Kaushlendra Kumar)"

Pull ACPI support updates from Rafael Wysocki:
"These include an update of the CMOS RTC driver and the related ACPI
and x86 code that, among other things, switches it over to using the
platform device interface for device binding on x86 instead of the PNP
device driver interface (which allows the code in question to be
simplified quite a bit), a major update of the ACPI Time and Alarm
Device (TAD) driver adding an RTC class device interface to it, and
updates of core ACPI drivers that remove some unnecessary and not
really useful code from them.
Apart from that, two drivers are converted to using the platform
driver interface for device binding instead of the ACPI driver one,
which is slated for removal, support for the Performance Limited
register is added to the ACPI CPPC library and there are some
janitorial updates of it and the related cpufreq CPPC driver, the ACPI
processor driver is fixed and cleaned up, and NVIDIA vendor CPER
record handler is added to the APEI GHES code.
Also, the interface for obtaining a CPU UID from ACPI is consolidated
across architectures and used for fixing a problem with the PCI TPH
Steering Tag on ARM64, there are two updates related to ACPICA, a
minor ACPI OS Services Layer (OSL) update, and a few assorted updates
related to ACPI tables parsing.
Specifics:
- Update maintainers information regarding ACPICA (Rafael Wysocki)
- Replace strncpy() with strscpy_pad() in acpi_ut_safe_strncpy()
(Kees Cook)
- Trigger an ordered system power off after encountering a fatal
error operator in AML (Armin Wolf)
- Enable ACPI FPDT parsing on LoongArch (Xi Ruoyao)
- Remove the temporary stop-gap acpi_pptt_cache_v1_full structure
from the ACPI PPTT parser (Ben Horgan)
- Add support for exposing ACPI FPDT subtables FBPT and S3PT (Nate
DeSimone)
- Address multiple assorted issues and clean up the code in the ACPI
processor idle driver (Huisong Li)
- Replace strlcat() in the ACPI processor idle drive with a better
alternative (Andy Shevchenko)
- Rearrange and clean up acpi_processor_errata_piix4() (Rafael
Wysocki)
- Move reference performance to capabilities and fix an uninitialized
variable in the ACPI CPPC library (Pengjie Zhang)
- Add support for the Performance Limited Register to the ACPI CPPC
library (Sumit Gupta)
- Add cppc_get_perf() API to read performance controls, extend
cppc_set_epp_perf() for FFH/SystemMemory, and make the ACPI CPPC
library warn on missing mandatory DESIRED_PERF register (Sumit
Gupta)
- Modify the cpufreq CPPC driver to update MIN_PERF/MAX_PERF in
target callbacks to allow it to control performance bounds via
standard scaling_min_freq and scaling_max_freq sysfs attributes and
add sysfs documentation for the Performance Limited Register to it
(Sumit Gupta)
- Add ACPI support to the platform device interface in the CMOS RTC
driver, make the ACPI core device enumeration code create a
platform device for the CMOS RTC, and drop CMOS RTC PNP device
support (Rafael Wysocki)
- Consolidate the x86-specific CMOS RTC handling with the ACPI TAD
driver and clean up the CMOS RTC ACPI address space handler (Rafael
Wysocki)
- Enable ACPI alarm in the CMOS RTC driver if advertised in ACPI FADT
and allow that driver to work without a dedicated IRQ if the ACPI
alarm is used (Rafael Wysocki)
- Clean up the ACPI TAD driver in various ways and add an RTC class
device interface, including both the RTC setting/reading and alarm
timer support, to it (Rafael Wysocki)
- Clean up the ACPI AC and ACPI PAD (processor aggregator device)
drivers (Rafael Wysocki)
- Rework checking for duplicate video bus devices and consolidate
pnp.bus_id workarounds handling in the ACPI video bus driver
(Rafael Wysocki)
- Update the ACPI core device drivers to stop setting
acpi_device_name() unnecessarily (Rafael Wysocki)
- Rearrange code using acpi_device_class() in the ACPI core device
drivers and update them to stop setting acpi_device_class()
unnecessarily (Rafael Wysocki)
- Define ACPI_AC_CLASS in one place (Rafael Wysocki)
- Convert the ni903x_wdt watchdog driver and the xen ACPI PAD driver
to bind to platform devices instead of ACPI devices (Rafael
Wysocki)
- Add devm_ghes_register_vendor_record_notifier(), use it in the PCI
hisi driver, and Add NVIDIA vendor CPER record handler (Kai-Heng
Feng)
- Consolidate the interface for obtaining a CPU UID from ACPI across
architectures and use it to address incorrect PCI TPH Steering Tag
on ARM64 resulting from the invalid assumption that the ACPI
Processor UID would always be the same as the corresponding logical
CPU ID in Linux (Chengwen Feng)"

Pull driver core updates from Danilo Krummrich:
"debugfs:
- Fix NULL pointer dereference in debugfs_create_str()
- Fix misplaced EXPORT_SYMBOL_GPL for debugfs_create_str()
- Fix soundwire debugfs NULL pointer dereference from uninitialized
firmware_file
device property:
- Make fwnode flags modifications thread safe; widen the field to
unsigned long and use set_bit() / clear_bit() based accessors
- Document how to check for the property presence
devres:
- Separate struct devres_node from its "subclasses" (struct devres,
struct devres_group); give struct devres_node its own release and
free callbacks for per-type dispatch
- Introduce struct devres_action for devres actions, avoiding the
ARCH_DMA_MINALIGN alignment overhead of struct devres
- Export struct devres_node and its init/add/remove/dbginfo
primitives for use by Rust Devres<T>
- Fix missing node debug info in devm_krealloc()
- Use guard(spinlock_irqsave) where applicable; consolidate unlock
paths in devres_release_group()
driver_override:
- Convert PCI, WMI, vdpa, s390/cio, s390/ap, and fsl-mc to the
generic driver_override infrastructure, replacing per-bus
driver_override strings, sysfs attributes, and match logic; fixes a
potential UAF from unsynchronized access to driver_override in bus
match() callbacks
- Simplify __device_set_driver_override() logic
kernfs:
- Send IN_DELETE_SELF and IN_IGNORED inotify events on kernfs file
and directory removal
- Add corresponding selftests for memcg
platform:
- Allow attaching software nodes when creating platform devices via a
new 'swnode' field in struct platform_device_info
- Add kerneldoc for struct platform_device_info
software node:
- Move software node initialization from postcore_initcall() to
driver_init(), making it available early in the boot process
- Move kernel_kobj initialization (ksysfs_init) earlier to support
the above
- Remove software_node_exit(); dead code in a built-in unit
SoC:
- Introduce of_machine_read_compatible() and of_machine_read_model()
OF helpers and export soc_attr_read_machine() to replace direct
accesses to of_root from SoC drivers; also enables
CONFIG_COMPILE_TEST coverage for these drivers
sysfs:
- Constify attribute group array pointers to
'const struct attribute_group *const *' in sysfs functions,
device_add_groups() / device_remove_groups(), and struct class
Rust:
- Devres:
- Embed struct devres_node directly in Devres<T> instead of going
through devm_add_action(), avoiding the extra allocation and the
unnecessary ARCH_DMA_MINALIGN alignment
- I/O:
- Turn IoCapable from a marker trait into a functional trait
carrying the raw I/O accessor implementation (io_read /
io_write), providing working defaults for the per-type Io
methods
- Add RelaxedMmio wrapper type, making relaxed accessors usable in
code generic over the Io trait
- Remove overloaded per-type Io methods and per-backend macros
from Mmio and PCI ConfigSpace
- I/O (Register):
- Add IoLoc trait and generic read/write/update methods to the Io
trait, making I/O operations parameterizable by typed locations
- Add register! macro for defining hardware register types with
typed bitfield accessors backed by Bounded values; supports
direct, relative, and array register addressing
- Add write_reg() / try_write_reg() and LocatedRegister trait
- Update PCI sample driver to demonstrate the register! macro
Example:
```
register! {
/// UART control register.
CTRL(u32) @ 0x18 {
/// Receiver enable.
19:19 rx_enable => bool;
/// Parity configuration.
14:13 parity ?=> Parity;
}
/// FIFO watermark and counter register.
WATER(u32) @ 0x2c {
/// Number of datawords in the receive FIFO.
26:24 rx_count;
/// RX interrupt threshold.
17:16 rx_water;
}
}
impl WATER {
fn rx_above_watermark(&self) -> bool {
self.rx_count() > self.rx_water()
}
}
fn init(bar: &pci::Bar<BAR0_SIZE>) {
let water = WATER::zeroed()
.with_const_rx_water::<1>(); // > 3 would not compile
bar.write_reg(water);
let ctrl = CTRL::zeroed()
.with_parity(Parity::Even)
.with_rx_enable(true);
bar.write_reg(ctrl);
}
fn handle_rx(bar: &pci::Bar<BAR0_SIZE>) {
if bar.read(WATER).rx_above_watermark() {
// drain the FIFO
}
}
fn set_parity(bar: &pci::Bar<BAR0_SIZE>, parity: Parity) {
bar.update(CTRL, |r| r.with_parity(parity));
}
```
- IRQ:
- Move 'static bounds from where clauses to trait declarations for
IRQ handler traits
- Misc:
- Enable the generic_arg_infer Rust feature
- Extend Bounded with shift operations, single-bit bool
conversion, and const get()
Misc:
- Make deferred_probe_timeout default a Kconfig option
- Drop auxiliary_dev_pm_ops; the PM core falls back to driver PM
callbacks when no bus type PM ops are set
- Add conditional guard support for device_lock()
- Add ksysfs.c to the DRIVER CORE MAINTAINERS entry
