sound updates for 6.15-rc1
We've received lots of commits at this time, as a result of various
cleanup and refactoring works as well as a few new drivers and the
generic SoundWire support. Most of changes are device-specific,
little about the core changes. Some highlights below:
Core:
* A couple of (rather minor) race fixes in ALSA sequencer code
* A regression fix in ALSA timer code that may lead to a deadlock
ASoC:
* A large series of code conversion to use modern terminology for the
clocking configuration
* Conversions of PM ops with the modern macros in all ASoC drivers
* Clarification of the control operations
* Prepartory work for more generic SoundWire SCDA controls
* Support for AMD ACP 7.x, AWINC WM88166, Everest ES8388, Intel AVS
PEAKVOL and GAIN DSP modules Mediatek MT8188 DMIC, NXP i.MX95,
nVidia Tegra interconnects, Rockchip RK3588 S/PDIF, Texas
Instruments SN012776 and TAS5770L, and Wolfson WM8904 DMICs
Others:
* Conversions of PM ops with the modern macros in the rest drivers
* USB-audio quirks and fixes for Presonus Studio, DJM-A9, CME
* HD-audio quirks and fixes ASUS, HP, Lenovo, and others
Note that the PR contains some changes from the tip tree for AMD code,
and it might give some merge conflict due to the rebase afterwards.

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).

Updates for the VDSO infrastructure:
- 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.

Updates for the core time/timer subsystem:
- 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.
- Small updates, cleanups and improvements

Pull vfs pidfs updates from Christian Brauner:
- Allow retrieving exit information after a process has been reaped
through pidfds via the new PIDFD_INTO_EXIT extension for the
PIDFD_GET_INFO ioctl. Various tools need access to information about
a process/task even after it has already been reaped.
Pidfd polling allows waiting on either task exit or for a task to
have been reaped. The contract for PIDFD_INFO_EXIT is simply that
EPOLLHUP must be observed before exit information can be retrieved,
i.e., exit information is only provided once the task has been reaped
and then can be retrieved as long as the pidfd is open.
- Add PIDFD_SELF_{THREAD,THREAD_GROUP} sentinels allowing userspace to
forgo allocating a file descriptor for their own process. This is
useful in scenarios where users want to act on their own process
through pidfds and is akin to AT_FDCWD.
- Improve premature thread-group leader and subthread exec behavior
when polling on pidfds:
(1) During a multi-threaded exec by a subthread, i.e.,
non-thread-group leader thread, all other threads in the
thread-group including the thread-group leader are killed and the
struct pid of the thread-group leader will be taken over by the
subthread that called exec. IOW, two tasks change their TIDs.
(2) A premature thread-group leader exit means that the thread-group
leader exited before all of the other subthreads in the
thread-group have exited.
Both cases lead to inconsistencies for pidfd polling with
PIDFD_THREAD. Any caller that holds a PIDFD_THREAD pidfd to the
current thread-group leader may or may not see an exit notification
on the file descriptor depending on when poll is performed. If the
poll is performed before the exec of the subthread has concluded an
exit notification is generated for the old thread-group leader. If
the poll is performed after the exec of the subthread has concluded
no exit notification is generated for the old thread-group leader.
The correct behavior is to simply not generate an exit notification
on the struct pid of a subhthread exec because the struct pid is
taken over by the subthread and thus remains alive.
But this is difficult to handle because a thread-group may exit
premature as mentioned in (2). In that case an exit notification is
reliably generated but the subthreads may continue to run for an
indeterminate amount of time and thus also may exec at some point.
After this pull no exit notifications will be generated for a
PIDFD_THREAD pidfd for a thread-group leader until all subthreads
have been reaped. If a subthread should exec before no exit
notification will be generated until that task exits or it creates
subthreads and repeates the cycle.
This means an exit notification indicates the ability for the father
to reap the child.

Pull vfs mount updates from Christian Brauner:
- Mount notifications
The day has come where we finally provide a new api to listen for
mount topology changes outside of /proc/<pid>/mountinfo. A mount
namespace file descriptor can be supplied and registered with
fanotify to listen for mount topology changes.
Currently notifications for mount, umount and moving mounts are
generated. The generated notification record contains the unique
mount id of the mount.
The listmount() and statmount() api can be used to query detailed
information about the mount using the received unique mount id.
This allows userspace to figure out exactly how the mount topology
changed without having to generating diffs of /proc/<pid>/mountinfo
in userspace.
- Support O_PATH file descriptors with FSCONFIG_SET_FD in the new mount
api
- Support detached mounts in overlayfs
Since last cycle we support specifying overlayfs layers via file
descriptors. However, we don't allow detached mounts which means
userspace cannot user file descriptors received via
open_tree(OPEN_TREE_CLONE) and fsmount() directly. They have to
attach them to a mount namespace via move_mount() first.
This is cumbersome and means they have to undo mounts via umount().
Allow them to directly use detached mounts.
- Allow to retrieve idmappings with statmount
Currently it isn't possible to figure out what idmapping has been
attached to an idmapped mount. Add an extension to statmount() which
allows to read the idmapping from the mount.
- Allow creating idmapped mounts from mounts that are already idmapped
So far it isn't possible to allow the creation of idmapped mounts
from already idmapped mounts as this has significant lifetime
implications. Make the creation of idmapped mounts atomic by allow to
pass struct mount_attr together with the open_tree_attr() system call
allowing to solve these issues without complicating VFS lookup in any
way.
The system call has in general the benefit that creating a detached
mount and applying mount attributes to it becomes an atomic operation
for userspace.
- Add a way to query statmount() for supported options
Allow userspace to query which mount information can be retrieved
through statmount().
- Allow superblock owners to force unmount

Drivers: hv: Introduce mshv_root module to expose /dev/mshv to VMMs
Provide a set of IOCTLs for creating and managing child partitions when running as root partition on Hyper-V. The new driver is enabled via CONFIG_MSHV_ROOT. A brief overview of the interface: MSHV_CREATE_PARTITION is the entry point, returning a file descriptor representing a child partition. IOCTLs on this fd can be used to map memory, create VPs, etc. Creating a VP returns another file descriptor representing that VP which in turn has another set of corresponding IOCTLs for running the VP, getting/setting state, etc. MSHV_ROOT_HVCALL is a generic "passthrough" hypercall IOCTL which can be used for a number of partition or VP hypercalls. This is for hypercalls that do not affect any state in the kernel driver, such as getting and setting VP registers and partition properties, translating addresses, etc. It is "passthrough" because the binary input and output for the hypercall is only interpreted by the VMM - the kernel driver does nothing but insert the VP and partition id where necessary (which are always in the same place), and execute the hypercall.

pidfs: ensure that PIDFS_INFO_EXIT is available
When we currently create a pidfd we check that the task hasn't been reaped right before we create the pidfd. But it is of course possible that by the time we return the pidfd to userspace the task has already been reaped since we don't check again after having created a dentry for it. This was fine until now because that race was meaningless. But now that we provide PIDFD_INFO_EXIT it is a problem because it is possible that the kernel returns a reaped pidfd and it depends on the race whether PIDFD_INFO_EXIT information is available. This depends on if the task gets reaped before or after a dentry has been attached to struct pid. Make this consistent and only returned pidfds for reaped tasks if PIDFD_INFO_EXIT information is available. This is done by performing another check whether the task has been reaped right after we attached a dentry to struct pid. Since pidfs_exit() is called before struct pid's task linkage is removed the case where the task got reaped but a dentry was already attached to struct pid and exit information was recorded and published can be handled correctly. In that case we do return a pidfd for a reaped task like we would've before.

posix-timers: Provide a mechanism to allocate a given timer ID
Checkpoint/Restore in Userspace (CRIU) requires to reconstruct posix timers
with the same timer ID on restore. It uses sys_timer_create() and relies on
the monotonic increasing timer ID provided by this syscall. It creates and
deletes timers until the desired ID is reached. This is can loop for a long
time, when the checkpointed process had a very sparse timer ID range.
It has been debated to implement a new syscall to allow the creation of
timers with a given timer ID, but that's tideous due to the 32/64bit compat
issues of sigevent_t and of dubious value.
The restore mechanism of CRIU creates the timers in a state where all
threads of the restored process are held on a barrier and cannot issue
syscalls. That means the restorer task has exclusive control.
This allows to address this issue with a prctl() so that the restorer
thread can do:
if (prctl(PR_TIMER_CREATE_RESTORE_IDS, PR_TIMER_CREATE_RESTORE_IDS_ON))
goto linear_mode;
create_timers_with_explicit_ids();
prctl(PR_TIMER_CREATE_RESTORE_IDS, PR_TIMER_CREATE_RESTORE_IDS_OFF);
This is backwards compatible because the prctl() fails on older kernels and
CRIU can fall back to the linear timer ID mechanism. CRIU versions which do
not know about the prctl() just work as before.
Implement the prctl() and modify timer_create() so that it copies the
requested timer ID from userspace by utilizing the existing timer_t
pointer, which is used to copy out the allocated timer ID on success.
If the prctl() is disabled, which it is by default, timer_create() works as
before and does not try to read from the userspace pointer.
There is no problem when a broken or rogue user space application enables
the prctl(). If the user space pointer does not contain a valid ID, then
timer_create() fails. If the data is not initialized, but constains a
random valid ID, timer_create() will create that random timer ID or fail if
the ID is already given out.
As CRIU must use the raw syscall to avoid manipulating the internal state
of the restored process, this has no library dependencies and can be
adopted by CRIU right away.
Recreating two timers with IDs 1000000 and 2000000 takes 1.5 seconds with
the create/delete method. With the prctl() it takes 3 microseconds.

uapi: Revert "bitops: avoid integer overflow in GENMASK(_ULL)"
This patch reverts 'commit c32ee3d9abd2("bitops: avoid integer overflow in
GENMASK(_ULL)")'.
The code generation can be shrink by over 1KB by reverting this commit.
Originally the commit claimed that clang would emit warnings using the
implementation at that time.
The patch was applied and tested against numerous compilers, including
gcc-13, gcc-12, gcc-11 cross-compiler, clang-17, clang-18 and clang-19.
Various warning levels were set (-W=0, -W=1, -W=2) and CONFIG_WERROR
disabled to complete the compilation. The results show that no compilation
errors or warnings were generated due to the patch.
The results of code size reduction are summarized in the following table.
The code size changes for clang are all zero across different versions,
so they're not listed in the table.
For NR_CPUS=64 on x86_64.
----------------------------------------------
| | gcc-13 | gcc-12 | gcc-11 |
----------------------------------------------
| old | 22438085 | 22453915 | 22302033 |
----------------------------------------------
| new | 22436816 | 22452913 | 22300826 |
----------------------------------------------
| new - old | -1269 | -1002 | -1207 |
----------------------------------------------
For NR_CPUS=1024 on x86_64.
----------------------------------------------
| | gcc-13 | gcc-12 | gcc-11 |
----------------------------------------------
| old | 22493682 | 22509812 | 22357661 |
----------------------------------------------
| new | 22493230 | 22509487 | 22357250 |
----------------------------------------------
| new - old | -452 | -325 | -411 |
----------------------------------------------
For arm64 architecture, gcc cross-compiler was used and QEMU was
utilized to execute a VM for a CPU-heavy workload to ensure no
side effects and that functionalities remained correct. The test
even demonstrated a positive result in terms of code size reduction:
* Before: 31660668
* After: 31658724
* Difference (After - Before): -1944
An analysis of multiple functions compiled with gcc-13 on x86_64 was
performed. In summary, the patch elimates one negation in almost
every use case. However, negative effects may occur in some cases,
such as the generation of additional "mov" instruction or increased
register usage. The use of "~_UL(0) << (l)" may even result in the
allocations of "%r*" registers instead of "%e*" registers (which are
32-bit registers) because the compiler cannot assume that the higher
bits are zero.
Yury:
We limit GENMASK() usage with the const_true(l > h) condition, and
most of users just call it with constant parameters. For those, the
actual implementation of the macro doesn't matter, and since it
triggered clang warnings back then, it was reasonable to workaround
the warnings on the kernel side.
Now that some find_bit() functions call GENMASK() with runtime
parameters (although the const_true() condition holds), this ended up
hurting the generated code, as I Hsin discovered. This is especially
bad because it hurts small_const_nbits() optimization, where people are
most concerned about generated code quality. So, revert it to the
original version for good.

KVM: arm64: Allow userspace to change the implementation ID registers
KVM's treatment of the ID registers that describe the implementation (MIDR, REVIDR, and AIDR) is interesting, to say the least. On the userspace-facing end of it, KVM presents the values of the boot CPU on all vCPUs and treats them as invariant. On the guest side of things KVM presents the hardware values of the local CPU, which can change during CPU migration in a big-little system. While one may call this fragile, there is at least some degree of predictability around it. For example, if a VMM wanted to present big-little to a guest, it could affine vCPUs accordingly to the correct clusters. All of this makes a giant mess out of adding support for making these implementation ID registers writable. Avoid breaking the rather subtle ABI around the old way of doing things by requiring opt-in from userspace to make the registers writable. When the cap is enabled, allow userspace to set MIDR, REVIDR, and AIDR to any non-reserved value and present those values consistently across all vCPUs.

mm/pkey: Add PKEY_UNRESTRICTED macro
Memory protection keys (pkeys) uapi has two macros for pkeys restrictions: - PKEY_DISABLE_ACCESS 0x1 - PKEY_DISABLE_WRITE 0x2 with implicit literal value of 0x0 that means "unrestricted". Code that works with pkeys has to use this literal value when implying that a pkey imposes no restrictions. This may reduce readability because 0 can be written in various ways (e.g. 0x0 or 0) and also because 0 in the context of pkeys can be mistaken for "no permissions" (akin PROT_NONE) while it actually means "no restrictions". This is important because pkeys are oftentimes used near mprotect() that uses PROT_ macros. This patch adds PKEY_UNRESTRICTED macro defined as 0x0.

ASoC: tas2764: Random patches from the Asahi Linux
Merge series from broonie@kernel.org: This is a random subset of the patches for the tas2764 driver that I found in the Asahi Linux tree which seemed to be clear fixes and improvements which apply easily to mainline without much effort, there's a bunch more work on the driver that should also be applicable. I've only build tested this. |

virtio_snd.h: clarify that controls depends on VIRTIO_SND_F_CTLS
As defined in the specification, the `controls` field in the configuration space is only valid/present if VIRTIO_SND_F_CTLS is negotiated. From https://docs.oasis-open.org/virtio/virtio/v1.3/virtio-v1.3.html: 5.14.4 Device Configuration Layout ... controls (driver-read-only) indicates a total number of all available control elements if VIRTIO_SND_F_CTLS has been negotiated. Let's use the same style used in virtio_blk.h to clarify this and to avoid confusion as happened in QEMU (see link).
