soc: drivers for 7.2
There are a few added drivers, but mostly the normal maintenance to drivers
for firmware, memory controller and other soc specific hadware:
- The NXP QuickEngine gets modern MSI support, which allows some cleanups to
the GICv3 irqchip chip driver
- A new SoC specific driver for the Renesas R-Car MFIS unit is added,
encapsulating support for the on-chip mailbox and hwspinlock
implementations that are not easily separated into individual
drivers
- The Qualcomm SoC drivers add support for additional SoC implementations,
and flexiblity around power managedment for the serial-engine driver
as well as probing the LLCC driver using custom hardware descriptions
inside of the device itself.
- Added support for the Samsung thermal management unit
- A cleanup to the Tegra 'PMC' driver interfaces to remove legacy
APIs and allow multiple PMC instances everywhere.
- Updates to the TI SCI and KNAS drivers to improve suspend/resume
support.
- Minor driver changes for mediatek, xilinx, allwinner, aspeed, tegra,
broadcom, amd, microchip and starfive specific drivers
- Memory controller updates for Tegra and Renesas for additional SoC
types and other improvements.
- Firmware driver updates for Arm FF-A, SMCCC and SCMI interfaces,
to update driver probing, object lifetimes and address minor bugs.

workqueue: Changes for v7.2
- Continued progress toward making alloc_workqueue() unbound by default:
more callers converted to WQ_PERCPU / system_percpu_wq / system_dfl_wq,
and new warnings for queues that use neither WQ_PERCPU nor WQ_UNBOUND
or the legacy system_wq / system_unbound_wq.
- Misc: drop the now-trivial apply_wqattrs_lock()/unlock() wrappers,
forbid the TEST_WORKQUEUE benchmark from being built-in, and fix a
spurious pointer level in the worker debug-dump path.

Driver core changes for 7.2-rc1
- deferred probe:
- Fix race where deferred probe timeout work could be permanently
canceled by using mod_delayed_work()
- Fix missing jiffies conversion in deferred_probe_extend_timeout()
- Guard timeout extension with delayed_work_pending() to prevent
premature firing
- Use system_percpu_wq instead of the deprecated system_wq
- Update deferred_probe_timeout documentation
- device:
- Replace direct struct device bitfield access (can_match, dma_iommu,
dma_skip_sync, dma_ops_bypass, state_synced, dma_coherent,
of_node_reused, offline, offline_disabled) with flag-based
accessors using bit operations
- Reject devices with unregistered buses
- Delete unused DEVICE_ATTR_PREALLOC()
- Add low-level device attribute macros with const show/store
callbacks, allowing device attributes to reside in read-only memory
- Move core device attributes to read-only memory
- Constify group array pointers in driver_add_groups() /
driver_remove_groups(), struct bus_type, and struct device_driver
- device property:
- Fix fwnode reference leak in fwnode_graph_get_endpoint_by_id()
- Initialize all fields of fwnode_handle in fwnode_init()
- Provide swnode_get()/swnode_put() wrappers around kobject_get/put()
- Allow passing struct software_node_ref_args pointers directly to
PROPERTY_ENTRY_REF()
- driver_override:
- Migrate amba, cdx, vmbus, and rpmsg to the generic driver_override
infrastructure, fixing a UAF from unsynchronized access to
driver_override in bus match() callbacks
- Remove the now-unused driver_set_override()
- firmware loader:
- Fix recursive lock deadlock in device_cache_fw_images() when async
work falls back to synchronous execution
- Fix device reference leak in firmware_upload_register()
- platform:
- Pass KBUILD_MODNAME through the platform driver registration macro
to create module symlinks in sysfs for built-in drivers; move
module_kset initialization to a pure_initcall and tegra cbb
registration to core_initcall to ensure correct ordering
- Pass THIS_MODULE implicitly through a coresight_init_driver() macro
- sysfs:
- Upgrade OOB write detection in sysfs_kf_seq_show() from printk to
WARN
- Add return value clamping to sysfs_kf_read()
- Rust:
- ACPI:
- Fix missing match data for PRP0001 by exporting
acpi_of_match_device()
- Auxiliary:
- Replace drvdata() with dedicated registration data on
auxiliary_device. drvdata() exposed the driver's bus device
private data beyond the driver's own scope, creating ordering
constraints and forcing the data to outlive all registrations
that access it. Registration data is instead scoped structurally
to the Registration object, making lifecycle ordering enforced
by construction rather than convention.
- Rust-native device driver lifetimes (HRT):
- Allow Rust device drivers to carry a lifetime parameter on their
bus device private data, tied to the device binding scope -- the
interval during which a bus device is bound to a driver. Device
resources like pci::Bar<'a> and IoMem<'a> can be stored directly
in the driver's bus device private data with a lifetime bounded
by the binding scope, so the compiler enforces at build time that
they do not outlive the binding. This removes Devres indirection
from every access site and eliminates try_access() failure paths
in destructors.
Bus driver traits use a Generic Associated Type (GAT)
Data<'bound> to introduce the lifetime on the private data,
rather than parameterizing the Driver trait itself. Auxiliary
registration data, where the lifetime is not introduced by a
trait callback but must be threaded through Registration, uses
the ForLt trait (a type-level abstraction for types generic over
a lifetime).
- Misc:
- Fix DT overlayed devices not probing by reverting the broken
treewide overlay fix and re-running fw_devlink consumer pickup when
an overlay is applied to a bound device
- Use root_device_register() for faux bus root device; add sanity
check for failed bus init
- Fix dev_has_sync_state() data race with READ_ONCE() and move it to
base.h
- Avoid spurious device_links warning when removing a device while
its supplier is unbinding
- Switch ISA bus to dynamic root device
- Fix suspicious RCU usage in kernfs_put()
- Remove devcoredump exit callback
- Constify devfreq_event_class

Thermal control updates for 7.2-rc1
- Rework the initialization and cleanup of thermal class cooling
devices to separate DT-based cooling device registration and
cooling device registration without DT (Daniel Lezcano, Ovidiu
Panait)
- Update the cooling device DT bindings to support 3-cell cooling
device representation, where the additional cell holds an ID to
select a cooling mechanism for devices that offer multiple cooling
mechanisms, and adjust the cooling device registration code
accordingly (Gaurav Kohli, Daniel Lezcano)
- Remove dead code from two functions in the thermal core and simplify
the unregistration of thermal governors (Rafael Wysocki)
- Fix critical temperature attribute removal handling in the generic
thermal zone hwmon support code and rework that code to register a

Rust changes for v7.2
Toolchain and infrastructure:
- Introduce support for the 'zerocopy' library [1][2]:
Fast, safe, compile error. Pick two.
Zerocopy makes zero-cost memory manipulation effortless. We write
`unsafe` so you don't have to.
It essentially provides derivable traits (e.g. 'FromBytes') and
macros (e.g. 'transmute!') for safely converting between byte
sequences and other types. Having such support allows us to remove
some 'unsafe' code.
It is among the most downloaded Rust crates and it is also used by
the Rust compiler itself.
It is licensed under "BSD-2-Clause OR Apache-2.0 OR MIT".
The crates are imported essentially as-is (only +2/-3 lines needed
to be adapted), plus SPDX identifiers. Upstream has since added the
SPDX identifiers as well as one of the tweaks at my request, thus
reducing our future diffs on updates -- I keep the details in one of
our usual live lists [3].
In total, it is about ~39k lines added, ~32k without counting
'benches/' which are just for documentation purposes.
The series includes a few Kbuild and rust-analyzer improvements and
an example patch using it in Nova, removing one 'unsafe impl'.
I checked that the codegen of an isolated example function (similar
to the Nova patch on top) is essentially identical. It also turns out
that (for that particular case) the 'zerocopy' version, even with
'debug-assertions' enabled, has no remaining panics, unlike a few in
the current code (since the compiler can prove the remaining
'ub_checks' statically).
So their "fast, safe" does indeed check out -- at least in that case.
Link: https://github.com/google/zerocopy [1]
Link: https://docs.rs/zerocopy [2]
Link: https://github.com/Rust-for-Linux/linux/issues/1239 [3]
- Support AutoFDO. This allows Rust code to be profiled and optimized
based on the profile. Tested with Rust Binder: ~13% slower without
AutoFDO in the binderAddInts benchmark (using an app-launch benchmark
for the profile).
- Support Software Tag-Based KASAN.
In addition, fix KASAN Kconfig by requiring Clang.
- Add Kconfig options for each existing Rust KUnit test suite, such as
'CONFIG_RUST_BITMAP_KUNIT_TEST'. They are placed within a new menu,
'CONFIG_RUST_KUNIT_TESTS', in the new 'rust/kernel/Kconfig.test'
file.
- Support the upcoming Rust 1.98.0 release (expected 2026-08-20): lint
cleanups and an unstable flag rename.
- Disable 'rustdoc' documentation inlining for all prelude items, which
bloats the generated documentation.
- Ignore (in Git) and clean (in Kbuild) the (rarely) 'rustc'-generated
'*.long-type-*.txt' files.
'kernel' crate:
- Add new 'bitfield' module with the 'bitfield!' macro (extracted from
the existing 'register!' one), which declares integer types that are
split into distinct bit fields of arbitrary length.
Each field is a 'Bounded' of the appropriate bit width (ensuring
values are properly validated and avoiding implicit data loss) and
gets several generated getters and setters (infallible, 'const' and
fallible) as well as associated constants ('_MASK', '_SHIFT' and
'_RANGE'). It also supports fields that can be converted from/to
custom types, either fallibly ('?=>') or infallibly ('=>').
For instance:
bitfield! {
struct Rgb(u16) {
15:11 blue;
10:5 green;
4:0 red;
}
}
// Compile-time checks.
let color = Rgb::zeroed().with_const_green::<0x1f>();
assert_eq!(color.green(), 0x1f);
assert_eq!(color.into_raw(), 0x1f << Rgb::GREEN_SHIFT);
Add as well documentation and a test suite for it, as usual; and
update the 'register!' macro to use it.
It will be maintained by Alexandre Courbot (with Yury Norov as
reviewer) under a new 'MAINTAINERS' entry: 'RUST [BITFIELD]'.
- 'ptr' module: rework index projection syntax into keyworded syntax
and introduce panicking variant.
The keyword syntax ('build:', 'try:', 'panic:') is more explicit and
paves the way of perhaps adding more flavors in the future, e.g. an
'unsafe' index projection.
For instance, projections now look like this:
fn f(p: *const [u8; 32]) -> Result {
// Ok, within bounds, checked at build time.
project!(p, [build: 1]);
// Build error.
project!(p, [build: 128]);
// `OutOfBound` runtime error (convertible to `ERANGE`).
project!(p, [try: 128]);
// Runtime panic.
project!(p, [panic: 128]);
Ok(())
}
Update as well the users, which now look like e.g.
// Pointer to the first entry of the GSP message queue.
let data = project!(self.0.as_ptr(), .gspq.msgq.data[build: 0]);
- 'build_assert' module: make the module the home of its macros instead
of rendering them twice.
- 'sync' module: add 'UniqueArc::as_ptr()' associated function.
- 'alloc' module:
+ Fix the 'Vec::reserve()' doctest to properly account for the
existing vector length in the capacity assertion.
+ Fix an incorrect operator in the 'Vec::extend_with()' 'SAFETY'
comment; add a doc test demonstrating basic usage and the
zero-length case.
- Clean imports across several modules to follow the "kernel vertical"
import style in order to minimize conflicts.
'pin-init' crate:
- User visible changes:
+ Do not generate 'non_snake_case' warnings for identifiers that are
syntactically just users of a field name. This would allow all
'#[allow(non_snake_case)]' in nova-core to be removed, which Gary
will send to the nova tree next cycle.
+ Filter non-cfg attributes out properly in derived structs. This
improves pin-init compatibility with other derive macros.
+ Insert projection types' where clause properly.
- Other changes:
+ Bump MSRV to 1.82, plus associated cleanups.
+ Overhaul how init slots are projected. The new approach is easier
to justify with safety comments.
+ Mark more functions as inline, which should help mitigate the
super-long symbol name issue due to lack of inlining.
rust-analyzer:
- Support '--envs' for passing env vars for crates like 'zerocopy'.
'MAINTAINERS':
- Add the following reviewers to the 'RUST' entry:
+ Daniel Almeida
+ Tamir Duberstein
+ Alexandre Courbot
+ Onur Özkan
They have been involved in the Rust for Linux project for about
7 collective years and bring expertise across several domains, which
will be very useful to have around in the future.
Thanks everyone for stepping up!
And some other fixes, cleanups and improvements.

drm/xe: fix job timeout recovery for unstarted jobs and kernel queues
A job that GuC never scheduled (never started) indicates a GuC
scheduling failure; previously such jobs were silently errored out
instead of triggering a GT reset to recover. Trigger a GT reset and
resubmit them, but only when the queue was not already killed or banned:
an unstarted job on an already banned queue is the ban working as
intended and must neither clear the ban nor kick off a reset, otherwise
a banned userspace queue could be resurrected and spam GT resets.
Kernel queues are always recovered this way and wedge the device once
recovery attempts are exhausted, since kernel work must not silently
fail. A started job that times out on a userspace VM bind queue stays
banned rather than being reset and retried.
The queue is banned early in the timeout handler to signal the G2H
scheduling-done handler so it wakes the disable-scheduling waiter;
without it the waiter sleeps the full 5s timeout. When a reset is
warranted the ban is cleared before rearming so that
guc_exec_queue_start() can resubmit jobs after the GT reset - a
still-banned queue would block resubmission and cause an infinite TDR
loop. The already-banned case is gated out before this point via
skip_timeout_check, so it is unaffected.
v2: (Himal) Do it for any queue type, not just kernel/migration
v3: - (Sashiko and Sanjay): don't clear the ban / GT reset for already
killed/banned queues on unstarted-job timeout
- Update commit message
- (Matt) Add Fixes tag

drm/xe: fix refcount leak in xe_range_fence_insert()
xe_range_fence_insert() acquires a reference on fence via dma_fence_get() and stores it in rfence->fence. It then calls dma_fence_add_callback() and handles two cases: when the callback is successfully registered (err == 0) the fence is transferred to the tree for later cleanup; when the fence is already signaled (err == -ENOENT) it manually drops the extra reference with dma_fence_put(fence). However, dma_fence_add_callback() can fail with other errors (e.g. -EINVAL) and in that case the code falls through to the free: label without releasing the acquired reference, leaking it. Fix the leak by adding an else branch that calls dma_fence_put() before jumping to free: for any error other than -ENOENT. Fixes: |

drm/xe: include all registered queues in TLB invalidation
Context-based TLB invalidation currently selects only scheduling-active
exec queues via q->ops->active(). During rebind flows, queues may be
suspended (or transitioning through resume) while still owning valid
translations, causing them to be skipped from invalidation and leading
to missed TLB invalidations on LR rebinds.
The underlying issue is a TOCTOU: q->guc->state bits are flipped lock-free
from enable_scheduling(), disable_scheduling{,_deregister}(), the
suspend/resume sched-msg handlers, handle_sched_done(), and
guc_exec_queue_stop(); nothing in send_tlb_inval_ctx_ppgtt() serializes
against them, so any state-based predicate can race.
Include all the registered queues so that TLB invalidations are not
missed. This is race-free because list membership on vm->exec_queues.list
is stable under vm->exec_queues.lock held by the caller. The performance
impact is expected to be minimal and harmless. If it does turn out to be
a concern, we can come back with a race-safe solution to ignore certain
queues.

drm/xe/display: fix oops in suspend/shutdown without display
The xe driver keeps track of whether to probe display, and whether display hardware is there, using xe->info.probe_display. It gets set to false if there's no display after intel_display_device_probe(). However, the display may also be disabled via fuses, detected at a later time in intel_display_device_info_runtime_init(). In this case, the xe driver does for_each_intel_crtc() on uninitialized mode config in xe_display_flush_cleanup_work(), leading to a NULL pointer dereference, and generally calls display code with display info cleared. Check for intel_display_device_present() after intel_display_device_info_runtime_init(), and reset xe->info.probe_display as necessary. Also do unset_display_features() for completeness, although display runtime init has already done that. This will need to be unified across all cases later. Move intel_display_device_info_runtime_init() call slightly earlier, similar to i915, to avoid a bunch of unnecessary setup for no display cases. Note #1: The xe driver has no business doing low level display plumbing like for_each_intel_crtc() to begin with. It all needs to happen in display code. Note #2: The actual bug is present already in commit |

rust: make build_assert module the home of related macros
Given the macro scoping rules, all macros are rendered twice, in the
module and in the top-level of kernel crate.
Add `#[doc(hidden)]` to the macro definition and `#[doc(inline)]` to the
re-export inside `build_assert` module so the top-level items are hidden.
[ Sadly, because the definition is hidden, `rustdoc` decides to not list
them as re-exports in the `prelude` page anymore, even if we refer to
the not-actually-hidden item.

drm/vc4: fix krealloc() memory leak
Don't just overwrite the original pointer passed to krealloc()
with its return value without checking latter:
MEM = krealloc(MEM, SZ, GFP);
If krealloc() returns NULL, that erases the pointer
to the still allocated memory, hence leaks this memory.
Instead, use a temporary variable, check it's not NULL
and only then assign it to the original pointer:
TMP = krealloc(MEM, SZ, GFP);
if (!TMP) return;
MEM = TMP;
While on it, use krealloc_array().

fbdev: Wrap fbcon updates from vga-switcheroo in helper
Handle console remapping in fbcon in fb_switch_output(). Vga-switcheroo invokes this functionality before switching physical outputs to a new graphics device. Open-coding fbcon state in vga-switcheroo exposed fbdev implementation details. Vga-switcheroo is used for switching physical outputs among graphics hardware. This functionality is only supported by DRM drivers. A later update will further move fb_switch_output() into DRM's fbdev emulation; thus fully decoupling vga-switcheroo from fbdev. v3: - remove Kconfig dependency related to fbcon (Geert) v2: - use '#if defined' (Helge) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Signed-off-by: Helge Deller <deller@gmx.de> |

drm/virtio: fix dma_fence refcount leak on error in virtio_gpu_dma_fence_wait()
dma_fence_unwrap_for_each() internally calls dma_fence_unwrap_first()
which does cursor->chain = dma_fence_get(head), taking an extra
reference. On normal loop completion, dma_fence_unwrap_next()
releases this via dma_fence_chain_walk() -> dma_fence_put().
When virtio_gpu_do_fence_wait() fails and the function returns early
from inside the loop, the cursor->chain reference is never released.
This is the only caller in the entire kernel that does an early return
inside dma_fence_unwrap_for_each.
Add dma_fence_put(itr.chain) before the early return.

DRM Rust changes for v7.2-rc1
- Driver Core (shared via signed tag dd-lifetimes-7.2-rc1):
- Introduce Higher-Ranked Lifetime Types (HRT) for Rust device
drivers, allowing driver structs to hold device resources like
pci::Bar and IoMem directly with a lifetime tied to the binding
scope, removing the need for Devres indirection and ARef<Device>.
- Replace drvdata() with scoped registration data on the auxiliary
bus, using the new ForLt trait to thread lifetimes through
registrations. Remove drvdata() and driver_type.
- DRM:
- Add GPUVM immediate mode abstraction for Rust GPU drivers:
- In immediate mode, GPU virtual address space state is updated
during job execution (in the DMA fence signalling critical path),
keeping the GPUVM and the GPU's address space always in sync.
- Provide GpuVm, GpuVa, and GpuVmBo types for managing address
spaces, virtual mappings, and GEM object backing respectively.
- Provide split-merge map/unmap operations that handle partial
overlaps with existing mappings.
- drm_exec integration for dma_resv locking and GEM object
validation based on the external/evicted object lists are not
yet covered and planned as follow-up work.
- Introduce DeviceContext type state for drm::Device, allowing
drivers to restrict operations to contexts where the device is
guaranteed to be registered (or not yet registered) with userspace.
- Add FEAT_RENDER flag to the Driver trait for render node support.
- Nova:
- Hopper/Blackwell enablement:
- Add GPU identification and architecture-based HAL selection for
Hopper (GH100) and Blackwell (GB100, GB202).
- Implement the FSP (Foundation Security Processor) boot path used by
Hopper and Blackwell, including FSP falcon engine support, EMEM
operations, MCTP/NVDM message infrastructure, and FSP Chain of
Trust boot with GSP lockdown release.
- Add support for 32-bit firmware images and auto-detection of
firmware image format.
- Add architecture-specific framebuffer, sysmem flush, PCI config
mirror, DMA mask, and WPR/non-WPR heap sizing.
- GSP boot and unload:
- Refactor the GSP boot process into a chipset-specific HAL,
keeping the SEC2 and FSP boot paths separated cleanly.
- Implement proper driver unload: send UNLOADING_GUEST_DRIVER
command, run Booter Unloader and FWSEC-SB upon unbinding, and run
the unload bundle on Gsp::boot() failure. This removes the need
for a manual GPU reset between driver unbind and re-probe.
- GA100 support:
- Add support for the GA100 GPU, including IFR header detection and
skipping, correct fwsignature selection, conditional FRTS boot,
and documentation of the IFR header layout.
- VBIOS hardening and refactoring:
- Harden VBIOS parsing with checked arithmetic, bounds-checked
accesses, and FromBytes-based structure reads throughout the FWSEC
and Falcon data paths. Simplify the overall VBIOS module
structure.
- HRT adoption:
- Use lifetime-parameterized pci::Bar directly, replacing the
Arc<Devres<Bar0>> indirection. Replace ARef<Device> with &'bound
Device in SysmemFlush and the GSP sequencer. Separate the driver
type from driver data.
- Misc:
- Rename module names to kebab-case (nova-drm, nova-core).
- Require little-endian in Kconfig, making the existing assumption
explicit.
- Tyr:
- Define comprehensive typed register blocks for GPU_CONTROL,
JOB_CONTROL, MMU_CONTROL (including per-address-space registers),
and DOORBELL_BLOCK using the kernel register!() macro. This replaces
manual bit manipulation with typed register and field accessors.
- Add shmem-backed GEM objects and set DMA mask based on GPU physical
address width.
- Adopt HRT: separate driver type from driver data, and use IoMem
directly instead of Devres for register access during probe.
- Move clock cleanup into a Drop implementation.

drm/amdkfd: Unwind debug trap enable on copy_to_user failure
If kfd_dbg_trap_enable() fails while copying runtime_info to userspace,
it had already activated the trap, set debug_trap_enabled, taken an extra
process reference, and opened the debug event file. Return -EFAULT without
unwinding that state, leaving inconsistent trap state and a refcount
imbalance that could break later DISABLE/ENABLE.
On copy_to_user failure, deactivate the trap and undo the rest of the
enable setup before returning.

drm/amdkfd: Add bounds check for AMDKFD_IOC_WAIT_EVENTS
The kfd_wait_on_events ioctl passes a user-supplied num_events parameter
directly to alloc_event_waiters() which calls kcalloc() without validation.
This allows unprivileged users with /dev/kfd access to trigger large kernel
memory allocations, potentially causing memory exhaustion and denial of
service via the OOM killer.
Add a check to reject num_events values exceeding KFD_SIGNAL_EVENT_LIMIT
(4096), which is the maximum number of events a single process can create.
