From: Mario Limonciello <mario.limonciello@amd.com>
Some platforms include a human presence detection (HPD) sensor. When
enabled and a user is detected a wake event will be emitted from the
sensor fusion hub that software can react to.
Example use cases are "wake from suspend on approach" or to "lock
when leaving".
This is currently enabled by default on supported systems, but users
can't control it. This essentially means that wake on approach is
enabled which is a really surprising behavior to users that don't
expect it.
Instead of defaulting to enabled add a sysfs knob that users can
use to enable the feature if desirable and set it to disabled by
default.

Pull gpio updates from Bartosz Golaszewski:
"There are no new drivers this time but several changes to the core
GPIO framework and various driver updates.
This release cycle, we're starting a relatively straightforward but
tedious rework of the GPIO consumer API: for historical reasons, the
gpiod_set_value() variants would return void. Not only that but the
GPIO provider interface does not even allow drivers to return a value
to GPIO core. This is because initial GPIO controllers would be MMIO
based and could not fail. We've had I2C, SPI and USB controllers for
years too but no way of indicating failures to callers.
This changes the consumer interface, adds new provider callbacks and
starts converting the drivers under drivers/gpio/ to using them. Once
this gets upstream, we'll keep on converting GPIO drivers that live
elsewhere and once there are no more users of the old callbacks, we'll
remove them and rename the new ones to the previous name. I imagine
the last step would happen in one sweeping change like what you did
for the remove_new() -> remove() renaming.
We've also addressed an issue where invalid return values from GPIO
drivers would get propagated to user-space by adding some
GPIO-core-level sanitization. Again: not a complex change but way
overdue.
Other than that: lots of driver and core refactoring, DT-bindings
changes and some other minor changes like coding style fixes or header
reordering.
GPIO core:
- add sanitization of return values of GPIO provider callbacks so
that invalid ones don't get propagated to user-space
- add new variants of the line setter callbacks for GPIO providers
that return an integer and allow to indicate driver errors to the
GPIO core
- change the interface of all gpiod_set_value() variants to return an
integer thus becoming able to indicate failures in the underlying
layer to callers
- drop unneeded ERR_CAST in gpiolib-acpi
- use for_each_if() where applicable
- provide gpiod_multi_set_value_cansleep() as a new, simpler
interface to gpiod_set_array_value_cansleep() and use it across
several drivers treewide
- reduce the number of atomic reads of the descriptor flags in
gpiolib debugfs code
- simplify for_each_hwgpio_in_range() and
for_each_requested_gpio_in_range()
- add support for three-cell GPIO specifiers in GPIO OF code
- don't build HTE (hardware timestamp engine) GPIO code with the HTE
subsystem disabled in Kconfig
- unduplicate calls to gpiod_direction_input_nonotify()
- rework the handling of the valid_mask property of GPIO chips: don't
allow drivers to set it as it should only be handled by GPIO core
and start actually enforcing it in GPIO core for *all* drivers, not
only the ones implementing a custom request() callback
- get the `ngpios` property from the fwnode of the GPIO chip, not its
device in order to handle multi-bank GPIO chips
Driver improvements:
- convert a part of the GPIO drivers under drivers/gpio/ to using the
new value setter callbacks
- convert several drivers to using automatic lock guards from
cleanup.h
- allow building gpio-bt8xx with COMPILE_TEST=y
- refactor gpio-74x164 (use devres, cleanup helpers, __counted_by()
and bits.h macros)
- refactor gpio-latch (use generic device properties, lock guards and
some local variables for better readability)
- refactor gpio-xilinx (improve the usage of the bitmap API)
- support multiple virtual GPIO controller instances in gpio-virtio
- allow gpio-regmap to use the standard `ngpios` property from
GPIOLIB
- factor out the common code for synchronous probing of virtual GPIO
devices into its own library
- use str_enable_disable(), str_high_low() and other string helpers
where applicable
- extend the gpio-mmio abstraction layer to allow calling into the
pinctrl back-end when setting direction
- convert gpio-vf610 to using the gpio-mmio library
- use more devres in gpio-adnp
- add support for reset-gpios in gpio-pcf857x
- add support for more models to gpio-loongson-64bit
DT bindings:
- add new compatibles to gpio-vf610 and gpio-loongson
- add missing gpio-ranges property to gpio-mvebu
- add reset-gpios to nxp,pcf8575
- enable gpio-hog parsing in ast2400-gpio

- coding style improvements
- kerneldoc fixes
- includes reordering
- updates to the TODO list"

Pull selinux updates from Paul Moore:
- Add additional SELinux access controls for kernel file reads/loads
The SELinux kernel file read/load access controls were never updated
beyond the initial kernel module support, this pull request adds
support for firmware, kexec, policies, and x.509 certificates.
- Add support for wildcards in network interface names
There are a number of userspace tools which auto-generate network
interface names using some pattern of <XXXX>-<NN> where <XXXX> is a
fixed string, e.g. "podman", and <NN> is a increasing counter.
Supporting wildcards in the SELinux policy for network interfaces
simplifies the policy associted with these interfaces.
- Fix a potential problem in the kernel read file SELinux code
SELinux should always check the file label in the
security_kernel_read_file() LSM hook, regardless of if the file is
being read in chunks. Unfortunately, the existing code only
considered the file label on the first chunk; this pull request fixes
this problem.
There is more detail in the individual commit, but thankfully the
existing code didn't expose a bug due to multi-stage reads only
taking place in one driver, and that driver loading a file type that
isn't targeted by the SELinux policy.
- Fix the subshell error handling in the example policy loader
Minor fix to SELinux example policy loader in scripts/selinux due to
an undesired interaction with subshells and errexit.

Pull lsm updates from Paul Moore:
- Various minor updates to the LSM Rust bindings
Changes include marking trivial Rust bindings as inlines and comment
tweaks to better reflect the LSM hooks.
- Add LSM/SELinux access controls to io_uring_allowed()
Similar to the io_uring_disabled sysctl, add a LSM hook to
io_uring_allowed() to enable LSMs a simple way to enforce security
policy on the use of io_uring. This pull request includes SELinux
support for this new control using the io_uring/allowed permission.
- Remove an unused parameter from the security_perf_event_open() hook
The perf_event_attr struct parameter was not used by any currently
supported LSMs, remove it from the hook.
- Add an explicit MAINTAINERS entry for the credentials code
We've seen problems in the past where patches to the credentials code
sent by non-maintainers would often languish on the lists for
multiple months as there was no one explicitly tasked with the
responsibility of reviewing and/or merging credentials related code.
Considering that most of the code under security/ has a vested
interest in ensuring that the credentials code is well maintained,
I'm volunteering to look after the credentials code and Serge Hallyn
has also volunteered to step up as an official reviewer. I posted the
MAINTAINERS update as a RFC to LKML in hopes that someone else would
jump up with an "I'll do it!", but beyond Serge it was all crickets.

Pull power management updates from Rafael Wysocki:
"These are dominated by cpufreq updates which in turn are dominated by
updates related to boost support in the core and drivers and
amd-pstate driver optimizations.
Apart from the above, there are some cpuidle updates including a
rework of the most recent idle intervals handling in the venerable
menu governor that leads to significant improvements in some
performance benchmarks, as the governor is now more likely to predict
a shorter idle duration in some cases, and there are updates of the
core device power management code, mostly related to system suspend
and resume, that should help to avoid potential issues arising when
the drivers of devices depending on one another want to use different
optimizations.
There is also a usual collection of assorted fixes and cleanups,
including removal of some unused code.
Specifics:
- Manage sysfs attributes and boost frequencies efficiently from
cpufreq core to reduce boilerplate code in drivers (Viresh Kumar)
- Minor cleanups to cpufreq drivers (Aaron Kling, Benjamin Schneider,
Dhananjay Ugwekar, Imran Shaik, zuoqian)
- Migrate some cpufreq drivers to using for_each_present_cpu() (Jacky
Bai)
- cpufreq-qcom-hw DT binding fixes (Krzysztof Kozlowski)
- Use str_enable_disable() helper in cpufreq_online() (Lifeng Zheng)
- Optimize the amd-pstate driver to avoid cases where call paths end
up calling the same writes multiple times and needlessly caching
variables through code reorganization, locking overhaul and tracing
adjustments (Mario Limonciello, Dhananjay Ugwekar)
- Make it possible to avoid enabling capacity-aware scheduling (CAS)
in the intel_pstate driver and relocate a check for out-of-band
(OOB) platform handling in it to make it detect OOB before checking
HWP availability (Rafael Wysocki)
- Fix dbs_update() to avoid inadvertent conversions of negative
integer values to unsigned int which causes CPU frequency selection
to be inaccurate in some cases when the "conservative" cpufreq
governor is in use (Jie Zhan)
- Update the handling of the most recent idle intervals in the menu
cpuidle governor to prevent useful information from being discarded
by it in some cases and improve the prediction accuracy (Rafael
Wysocki)
- Make it possible to tell the intel_idle driver to ignore its
built-in table of idle states for the given processor, clean up the
handling of auto-demotion disabling on Baytrail and Cherrytrail
chips in it, and update its MAINTAINERS entry (David Arcari, Artem
Bityutskiy, Rafael Wysocki)
- Make some cpuidle drivers use for_each_present_cpu() instead of
for_each_possible_cpu() during initialization to avoid issues
occurring when nosmp or maxcpus=0 are used (Jacky Bai)
- Clean up the Energy Model handling code somewhat (Rafael Wysocki)
- Use kfree_rcu() to simplify the handling of runtime Energy Model
updates (Li RongQing)
- Add an entry for the Energy Model framework to MAINTAINERS as
properly maintained (Lukasz Luba)
- Address RCU-related sparse warnings in the Energy Model code
(Rafael Wysocki)
- Remove ENERGY_MODEL dependency on SMP and allow it to be selected
when DEVFREQ is set without CPUFREQ so it can be used on a wider
range of systems (Jeson Gao)
- Unify error handling during runtime suspend and runtime resume in
the core to help drivers to implement more consistent runtime PM
error handling (Rafael Wysocki)
- Drop a redundant check from pm_runtime_force_resume() and rearrange
documentation related to __pm_runtime_disable() (Rafael Wysocki)
- Rework the handling of the "smart suspend" driver flag in the PM
core to avoid issues hat may occur when drivers using it depend on
some other drivers and clean up the related PM core code (Rafael
Wysocki, Colin Ian King)
- Fix the handling of devices with the power.direct_complete flag set
if device_suspend() returns an error for at least one device to
avoid situations in which some of them may not be resumed (Rafael
Wysocki)
- Use mutex_trylock() in hibernate_compressor_param_set() to avoid a
possible deadlock that may occur if the "compressor" hibernation
module parameter is accessed during the registration of a new
ieee80211 device (Lizhi Xu)
- Suppress sleeping parent warning in device_pm_add() in the case
when new children are added under a device with the
power.direct_complete set after it has been processed by
device_resume() (Xu Yang)
- Remove needless return in three void functions related to system
wakeup (Zijun Hu)
- Replace deprecated kmap_atomic() with kmap_local_page() in the
hibernation core code (David Reaver)
- Remove unused helper functions related to system sleep (David Alan
Gilbert)
- Clean up s2idle_enter() so it does not lock and unlock CPU offline
in vain and update comments in it (Ulf Hansson)
- Clean up broken white space in dpm_wait_for_children() (Geert
Uytterhoeven)

Pull ACPI updates from Rafael Wysocki:
"From the functional perspective, the most significant changes here are
the ACPI fan driver update allowing it to handle fans with
fine-grained state checking supported, but without fine-grained

system event notifications (in addition to device notifications) which
on some systems is requisite for waking up the system from sleep.
The rest is fixes and cleanups including removal of some dead code.

Pull kvm updates from Paolo Bonzini:
"ARM:
- Nested virtualization support for VGICv3, giving the nested
hypervisor control of the VGIC hardware when running an L2 VM
- Removal of 'late' nested virtualization feature register masking,
making the supported feature set directly visible to userspace
- Support for emulating FEAT_PMUv3 on Apple silicon, taking advantage
of an IMPLEMENTATION DEFINED trap that covers all PMUv3 registers
- Paravirtual interface for discovering the set of CPU
implementations where a VM may run, addressing a longstanding issue
of guest CPU errata awareness in big-little systems and
cross-implementation VM migration
- Userspace control of the registers responsible for identifying a
particular CPU implementation (MIDR_EL1, REVIDR_EL1, AIDR_EL1),
allowing VMs to be migrated cross-implementation
- pKVM updates, including support for tracking stage-2 page table
allocations in the protected hypervisor in the 'SecPageTable' stat
- Fixes to vPMU, ensuring that userspace updates to the vPMU after
KVM_RUN are reflected into the backing perf events
LoongArch:
- Remove unnecessary header include path
- Assume constant PGD during VM context switch
- Add perf events support for guest VM
RISC-V:
- Disable the kernel perf counter during configure
- KVM selftests improvements for PMU
- Fix warning at the time of KVM module removal
x86:
- Add support for aging of SPTEs without holding mmu_lock.
Not taking mmu_lock allows multiple aging actions to run in
parallel, and more importantly avoids stalling vCPUs. This includes
an implementation of per-rmap-entry locking; aging the gfn is done
with only a per-rmap single-bin spinlock taken, whereas locking an
rmap for write requires taking both the per-rmap spinlock and the
mmu_lock.
Note that this decreases slightly the accuracy of accessed-page
information, because changes to the SPTE outside aging might not
use atomic operations even if they could race against a clear of
the Accessed bit.
This is deliberate because KVM and mm/ tolerate false
positives/negatives for accessed information, and testing has shown
that reducing the latency of aging is far more beneficial to
overall system performance than providing "perfect" young/old
information.
- Defer runtime CPUID updates until KVM emulates a CPUID instruction,
to coalesce updates when multiple pieces of vCPU state are
changing, e.g. as part of a nested transition
- Fix a variety of nested emulation bugs, and add VMX support for
synthesizing nested VM-Exit on interception (instead of injecting
#UD into L2)
- Drop "support" for async page faults for protected guests that do
not set SEND_ALWAYS (i.e. that only want async page faults at CPL3)
- Bring a bit of sanity to x86's VM teardown code, which has
accumulated a lot of cruft over the years. Particularly, destroy
vCPUs before the MMU, despite the latter being a VM-wide operation
- Add common secure TSC infrastructure for use within SNP and in the
future TDX
- Block KVM_CAP_SYNC_REGS if guest state is protected. It does not
make sense to use the capability if the relevant registers are not
available for reading or writing
- Don't take kvm->lock when iterating over vCPUs in the suspend
notifier to fix a largely theoretical deadlock
- Use the vCPU's actual Xen PV clock information when starting the
Xen timer, as the cached state in arch.hv_clock can be stale/bogus
- Fix a bug where KVM could bleed PVCLOCK_GUEST_STOPPED across
different PV clocks; restrict PVCLOCK_GUEST_STOPPED to kvmclock, as
KVM's suspend notifier only accounts for kvmclock, and there's no
evidence that the flag is actually supported by Xen guests
- Clean up the per-vCPU "cache" of its reference pvclock, and instead
only track the vCPU's TSC scaling (multipler+shift) metadata (which
is moderately expensive to compute, and rarely changes for modern
setups)
- Don't write to the Xen hypercall page on MSR writes that are
initiated by the host (userspace or KVM) to fix a class of bugs
where KVM can write to guest memory at unexpected times, e.g.
during vCPU creation if userspace has set the Xen hypercall MSR
index to collide with an MSR that KVM emulates
- Restrict the Xen hypercall MSR index to the unofficial synthetic
range to reduce the set of possible collisions with MSRs that are
emulated by KVM (collisions can still happen as KVM emulates
Hyper-V MSRs, which also reside in the synthetic range)
- Clean up and optimize KVM's handling of Xen MSR writes and
xen_hvm_config
- Update Xen TSC leaves during CPUID emulation instead of modifying
the CPUID entries when updating PV clocks; there is no guarantee PV
clocks will be updated between TSC frequency changes and CPUID
emulation, and guest reads of the TSC leaves should be rare, i.e.
are not a hot path
x86 (Intel):
- Fix a bug where KVM unnecessarily reads XFD_ERR from hardware and
thus modifies the vCPU's XFD_ERR on a #NM due to CR0.TS=1
- Pass XFD_ERR as the payload when injecting #NM, as a preparatory
step for upcoming FRED virtualization support
- Decouple the EPT entry RWX protection bit macros from the EPT
Violation bits, both as a general cleanup and in anticipation of
adding support for emulating Mode-Based Execution Control (MBEC)
- Reject KVM_RUN if userspace manages to gain control and stuff
invalid guest state while KVM is in the middle of emulating nested
VM-Enter
- Add a macro to handle KVM's sanity checks on entry/exit VMCS
control pairs in anticipation of adding sanity checks for secondary
exit controls (the primary field is out of bits)
x86 (AMD):
- Ensure the PSP driver is initialized when both the PSP and KVM
modules are built-in (the initcall framework doesn't handle
dependencies)
- Use long-term pins when registering encrypted memory regions, so
that the pages are migrated out of MIGRATE_CMA/ZONE_MOVABLE and
don't lead to excessive fragmentation
- Add macros and helpers for setting GHCB return/error codes
- Add support for Idle HLT interception, which elides interception if
the vCPU has a pending, unmasked virtual IRQ when HLT is executed
- Fix a bug in INVPCID emulation where KVM fails to check for a
non-canonical address
- Don't attempt VMRUN for SEV-ES+ guests if the vCPU's VMSA is
invalid, e.g. because the vCPU was "destroyed" via SNP's AP
Creation hypercall
- Reject SNP AP Creation if the requested SEV features for the vCPU
don't match the VM's configured set of features
Selftests:
- Fix again the Intel PMU counters test; add a data load and do
CLFLUSH{OPT} on the data instead of executing code. The theory is
that modern Intel CPUs have learned new code prefetching tricks
that bypass the PMU counters
- Fix a flaw in the Intel PMU counters test where it asserts that an
event is counting correctly without actually knowing what the event
counts on the underlying hardware
- Fix a variety of flaws, bugs, and false failures/passes
dirty_log_test, and improve its coverage by collecting all dirty
entries on each iteration
- Fix a few minor bugs related to handling of stats FDs
- Add infrastructure to make vCPU and VM stats FDs available to tests
by default (open the FDs during VM/vCPU creation)
- Relax an assertion on the number of HLT exits in the xAPIC IPI test
when running on a CPU that supports AMD's Idle HLT (which elides
interception of HLT if a virtual IRQ is pending and unmasked)"

Pull VDSO infrastructure updates from Thomas Gleixner:
- Consolidate the VDSO storage
The VDSO data storage and data layout has been largely architecture
specific for historical reasons. That increases the maintenance
effort and causes inconsistencies over and over.
There is no real technical reason for architecture specific layouts
and implementations. The architecture specific details can easily be
integrated into a generic layout, which also reduces the amount of
duplicated code for managing the mappings.
Convert all architectures over to a unified layout and common mapping
infrastructure. This splits the VDSO data layout into subsystem
specific blocks, timekeeping, random and architecture parts, which
provides a better structure and allows to improve and update the
functionalities without conflict and interaction.
- Rework the timekeeping data storage
The current implementation is designed for exposing system
timekeeping accessors, which was good enough at the time when it was
designed.
PTP and Time Sensitive Networking (TSN) change that as there are
requirements to expose independent PTP clocks, which are not related
to system timekeeping.
Replace the monolithic data storage by a structured layout, which
allows to add support for independent PTP clocks on top while reusing
both the data structures and the time accessor implementations.

Pull timer cleanups from Thomas Gleixner:
"A treewide hrtimer timer cleanup
hrtimers are initialized with hrtimer_init() and a subsequent store to
the callback pointer. This turned out to be suboptimal for the
upcoming Rust integration and is obviously a silly implementation to
begin with.
This cleanup replaces the hrtimer_init(T); T->function = cb; sequence
with hrtimer_setup(T, cb);
The conversion was done with Coccinelle and a few manual fixups.
Once the conversion has completely landed in mainline, hrtimer_init()
will be removed and the hrtimer::function becomes a private member"

Pull timer core updates from Thomas Gleixner:
- Fix a memory ordering issue in posix-timers
Posix-timer lookup is lockless and reevaluates the timer validity
under the timer lock, but the update which validates the timer is not
protected by the timer lock. That allows the store to be reordered
against the initialization stores, so that the lookup side can
observe a partially initialized timer. That's mostly a theoretical
problem, but incorrect nevertheless.
- Fix a long standing inconsistency of the coarse time getters
The coarse time getters read the base time of the current update
cycle without reading the actual hardware clock. NTP frequency
adjustment can set the base time backwards. The fine grained
interfaces compensate this by reading the clock and applying the new
conversion factor, but the coarse grained time getters use the base
time directly. That allows the user to observe time going backwards.
Cure it by always forwarding base time, when NTP changes the
frequency with an immediate step.
- Rework of posix-timer hashing
The posix-timer hash is not scalable and due to the CRIU timer
restore mechanism prone to massive contention on the global hash
bucket lock.
Replace the global hash lock with a fine grained per bucket locking
scheme to address that.
- Rework the proc/$PID/timers interface.
/proc/$PID/timers is provided for CRIU to be able to restore a timer.
The printout happens with sighand lock held and interrupts disabled.
That's not required as this can be done with RCU protection as well.
- Provide a sane mechanism for CRIU to restore a timer ID
CRIU restores timers by creating and deleting them until the kernel
internal per process ID counter reached the requested ID. That's
horribly slow for sparse timer IDs.
Provide a prctl() which allows CRIU to restore a timer with a given
ID. When enabled the ID pointer is used as input pointer to read the
requested ID from user space. When disabled, the normal allocation
scheme (next ID) is active as before. This is backwards compatible
for both kernel and user space.
- Make hrtimer_update_function() less expensive.
The sanity checks are valuable, but expensive for high frequency
usage in io/uring. Make the debug checks conditional and enable them
only when lockdep is enabled.

Pull irq driver updates from Thomas Gleixner:
- Support for hard indices on RISC-V. The hart index identifies a hart
(core) within a specific interrupt domain in RISC-V's Priviledged
Architecture.
- Rework of the RISC-V MSI driver
This moves the driver over to the generic MSI library and solves the
affinity problem of unmaskable PCI/MSI controllers. Unmaskable
PCI/MSI controllers are prone to lose interrupts when the MSI message
is updated to change the affinity because the message write consists
of three 32-bit subsequent writes, which update address and data. As
these writes are non-atomic versus the device raising an interrupt,
the device can observe a half written update and issue an interrupt
on the wrong vector. This is mitiated by a carefully orchestrated
step by step update and the observation of an eventually pending
interrupt on the CPU which issues the update. The algorithm follows
the well established method of the X86 MSI driver.
- A new driver for the RISC-V Sophgo SG2042 MSI controller
- Overhaul of the Renesas RZQ2L driver
Simplification of the probe function by using devm_*() mechanisms,
which avoid the endless list of error prone gotos in the failure
paths.
- Expand the Renesas RZV2H driver to support RZ/G3E SoCs
- A workaround for Rockchip 3568002 erratum in the GIC-V3 driver to
ensure that the addressing is limited to the lower 32-bit of the

This patch applies the ALC294 bass speaker fixup (ALC294_FIXUP_BASS_SPEAKER_15),
previously introduced in commit a7df7f909cec ("ALSA: hda: improve bass
speaker support for ASUS Zenbook UM5606WA"), to the ASUS Zenbook UM5606KA.
This hardware configuration matches ASUS Zenbook UM5606WA, where DAC NID
0x06 was removed from the bass speaker (NID 0x15), routing both speaker
pins to DAC NID 0x03.
This resolves the bass speaker routing issue, ensuring correct audio
output on ASUS UM5606KA.

We've had this before: when we remove infrastructure to generate files,
the old stale build artifacts still remain in-tree. And when the
infrastructure to generate them is gone, so is the gitignore file for
those build artifacts.
End result: git will see the old generated files, and people will
mistakenly commit them. That's what happened with the 'genheaders' file
not that long ago (see commit 04a3389b3535 "Remove stale generated
'genheaders' file").
This time it's commit 9c54baab4401 ("x86/boot: Drop CRC-32 checksum and
the build tool that generates it") that removed the 'build' file from
the arch/x86/boot/tools/ subdirectory, and removed the .gitignore file
too (because the whole subdirectory is gone).
And as a result, if you don't do a 'git clean -dqfx' or similar to clean
up your tree, 'git status' will say
Untracked files:
(use "git add <file>..." to include in what will be committed)
arch/x86/boot/tools/
and some hapless sleep-deprived developer will inevitably decide that
that means that they need to 'git add' that directory. Which would
bring back some stale generated file that we most definitely do not want
in the tree.
So when removing directories that had special .gitignore patterns, make
sure to add a new gitignore entry in the parent directory for the no
longer existing subdirectory.
It will avoid mistakes.
