drm/gpusvm: move struct drm_gpusvm_pages out of struct drm_gpusvm_range
Since the pages the physical pages and MM VA range has been abstractly
separated. Unbinding a single form of physical page from the MM VA
range, brings flexibility to the drm gpu SVM framework, transfer the
way of management of MM and device physical pages to the driver layer.
framework's range embedded pages object and its range level wrappers
have no users left. Remove the following:
- Drop pages in drm_gpusvm_range.
- Drop drm_gpusvm_range_pages_valid(), drm_gpusvm_range_get_pages()
and drm_gpusvm_range_unmap_pages(); drivers should use the
drm_gpusvm_pages helpers (drm_gpusvm_pages_valid,
drm_gpusvm_get_pages, drm_gpusvm_unmap_pages) directly on a
pages object they own.
- Drop the notifier_seq seeding in drm_gpusvm_range_alloc();
drivers initialise notifier_seq on their own pages object.
Update the DOC: overview to match the new model: document struct
drm_gpusvm_pages and the driver owned 1:1 / N:1 layouts, and rewrite the
usage examples to operate on a driver embedded pages object by the
drm_gpusvm_pages helpers instead of the removed range level wrappers.

drm/xe: have xe_svm_range embed one drm_gpusvm_pages
With drm_gpusvm_pages now self contained, make xe stop relying
on the drm_gpusvm_range pages and take responsibility for the page
lifecycle on the driver side.
Driver side (xe):
- Embed struct drm_gpusvm_pages in xe_svm_range and route all
xe accesses through it instead of range->base.pages.
- Initialise the embedded pages via drm_gpusvm_init_pages(), which
binds the owning &xe->drm up front, and take over the page
lifecycle: xe_svm_range_get_pages() calls drm_gpusvm_get_pages()
directly; the notifier event_end and xe_svm_range_free() paths
drive unmap/free on the embedded pages object.
- Convert the open-coded userptr pages init in xe_userptr_setup()
to the same drm_gpusvm_init_pages() helper.
- Switch xe_svm_range_pages_valid() to drm_gpusvm_pages_valid().
Framework side (drm_gpusvm):
- Add a small inline drm_gpusvm_init_pages() helper that records the
owning drm_device and initialises the per-pages state, giving
drivers a single hook to extend.
- Export drm_gpusvm_pages_valid() to let driver owned pages
can query mapping state without going through a range.
- Lifecycle change: drm_gpusvm_range_remove() no longer *triggers*
unmap/free of the embedded pages. The unmap/free logic itself stays
in the framework -- drm_gpusvm_free_pages() still performs the DMA
unmap (as an idempotent backstop) and frees the dma_addr array --
but the driver now owns *when* it runs, since the driver owns the
drm_gpusvm_pages object.
Side effect / contract: a driver that owns a drm_gpusvm_pages is now
responsible for its lifecycle: drm_gpusvm_init_pages() before first
use, and drm_gpusvm_free_pages() when the owner goes away. Xe does the
latter from its ops->range_free callback, which the framework invokes
once the range refcount drops to zero in drm_gpusvm_range_remove().
The timely DMA unmap for the IOMMU security model still happens in the
notifier invalidate path via drm_gpusvm_unmap_pages(); the unmap inside
drm_gpusvm_free_pages() is only a backstop for pages that were never
invalidated.

drm/gpusvm: embed struct drm_device into drm_gpusvm_pages
drm_gpusvm_pages is the layer that actually represents physical
pages/mappings it owns the dma_addr array, the dma_iova_state...
With the previous patch, so drm_gpusvm_pages is now strictly about
physical pages and their DMA view.
Since now the drm_gpusvm_pages instance is inherently bound to one
specific drm_device, make that ownership explicit by giving
drm_gpusvm_pages its own drm_device handle, and drive all DMA through
it instead of through the gpusvm:
- Add drm to struct drm_gpusvm_pages and route all DMA in
drm_gpusvm_get_pages() / __drm_gpusvm_unmap_pages() through
svm_pages->drm instead of gpusvm->drm.
- Bind svm_pages->drm where the pages object is initialised
(drm_gpusvm_range_alloc() and the xe userptr setup) and require
it to be set on entry to drm_gpusvm_get_pages(); the dma device
is immutable for the lifetime of the pages instance. A later
patch introduces drm_gpusvm_init_pages() to centralise this.

drm/gpusvm: split MM state flags out of drm_gpusvm_pages_flags
drm_gpusvm_pages_flags currently mixes two status:
- MM / virtual-address state: whether the range has been (partially)
unmapped by the Linux MM, these follow the lifetime of the VMA and
are a single per VA range fact.
- Device mapping state: has_devmem_pages and has_dma_mapping,
which describe the current page mapping status held by device
itself.
Keeping both on the pages object blurs the semantics of the
abstraction of pages and VA range. So move the MM state flags onto the
range, and keep drm_gpusvm_pages_flags strictly for mapping state.
- Introduce drm_gpusvm_range_flags { migrate_devmem, unmapped,
partial_unmap } on drm_gpusvm_range.
- Shrink drm_gpusvm_pages_flags to just has_devmem_pages and
has_dma_mapping.
Side effect: drivers now need to check the unmap flags in the driver
itself to avoid handling the unmapped pages.
Mirror that bit onto drm_gpusvm_pages so the framework can
still short circuit drm_gpusvm_get_pages() under the notifier lock, and
make drm_gpusvm_range_set_unmapped() propagate it to the backing pages.
This follows Matt's review fixup for the v0 series; see the Link below.
Like drm_gpusvm_pages_flags, drm_gpusvm_range_flags unions its bits with
a u16 __flags member. Build the new value in a local copy and publish it
with a single WRITE_ONCE() on __flags, and have the lockless readers use
READ_ONCE(), so concurrent bitfield access stays data-race free and KCSAN
quiet.

drm/v3d: bound CPU-job query writes to their destination BO
The V3D_SUBMIT_CPU CPU jobs take user-supplied offsets and indices and
consume them at exec time without checking that the accesses stay inside
their BO:
- TIMESTAMP_QUERY and RESET_TIMESTAMP_QUERY write one u64 per query
into bo[0] at a fully user-controlled per-query offset.
- COPY_TIMESTAMP_QUERY copies one u64 per query into bo[0] at
offset + i * stride, and reads each result from a user-controlled
offset in the source bo[1].
- COPY_PERFORMANCE_QUERY writes nperfmons * DRM_V3D_MAX_PERF_COUNTERS
counter slots plus an availability slot into bo[0] at the same
geometry.
- INDIRECT_CSD reads three u32 work-group counts from bo[0] at a
user-controlled offset, then writes each count back into the
indirect BO at a user-controlled u32 index (wg_uniform_offsets[]).
A render-node user (DRM_RENDER_ALLOW, no master, no capability) can make
the handlers read or write past a BO's vmap mapping.
Validate the full access extent against the BO size once the BOs are
looked up, before the job is queued, rejecting out-of-range geometry
with -EINVAL. The copy extent offset + (count - 1) * stride + write_size
is computed in u64, mirroring the u8 * pointer arithmetic in the
executors: (count - 1) * stride is a u32 * u32 product that is exact in
u64, so one overflow check on the total guards the bound. The
performance slot count and the bare timestamp, copy-source and indirect
offsets are computed in u64 the same way, so a user value cannot wrap
the comparison.

drm/v3d: Use write_to_buffer() helper in performance query copy

drm/v3d: Serialize jobs across queues when a perfmon is attached
A non-global perfmon is meant to count events generated by a specific
submission, but the scheduler can run jobs from different queues
concurrently on the same V3D core. Without explicit serialization, an
unrelated job running in parallel with a perfmon-carrying job pollutes
the counters and generates unusable results.
To address such issue, we must enforce cross-queue serialization when we
detect a perfmon-carrying submission. It's possible to implement
serialization by enforcing two rules:
1. A job that carries a non-global perfmon must wait for every job
currently in-flight across all HW queues to finish.
2. While a perfmon-carrying job is still in-flight, all subsequently
submitted jobs must wait for it.
Note that serialization is not needed in the global perfmon case, as the
global perfmon tracks activity from all jobs, so concurrency is desirable.
Therefore, check if serialization is needed during job submission and if
so, attach fence dependences to enforce cross-queue serialization.

drm/v3d: Refactor perfmon locking
v3d exposes a single set of performance counters per core, so at any
moment at most one performance monitor can be programmed in HW. In
software, this singleton is represented by v3d_dev->active_perfmon, but
until now nothing actually serialized access to it: scheduler callbacks,
the GPU-reset path, and perfmon ioctls all read and wrote that field
lock-free.
The existence of v3d_perfmon->lock mutex did not close the gap. It
serialized start/stop of *one* perfmon object against itself, but the
invariant that needs protection is device-wide: there can be exactly one
active perfmon at any moment in HW. Two threads acting on different
perfmon objects could race through v3d_dev->active_perfmon and the
counter registers, leaving software and HW out of sync.
This commit moves the locking to where the invariant actually lives. Group
the active perfmon pointer with a device-wide spinlock and route every
state transition (job start, job completion, set global, reset,
suspend/resume, destruction) through a small set of locked entry points
that are the only mutators of the HW counters.
Some design improvements needed to be made for the refactor:
1. Stop the perfmon from the IRQ handler at job-completion time (the
natural boundary for "active perfmon follows the active job"). This
required a change from a mutex to a spinlock. This solves another
issue of the existing design: perfmon start/stop was exclusively
attached to run_job() callbacks, which means that if nothing was
further queued up, a perfmon would never actually be stopped.
2. Pause/resume the HW counters across runtime-PM transitions without
dropping the software reference. This preserves the perfmon state
while the device is idle.
3. Move the global perfmon lifecycle management to the set_global
IOCTL. This simplifies the logic in v3d_perfmon_start() and
v3d_perfmon_stop(), as there is no need to always check if the
global perfmon is enabled.
4. v3d_perfmon_get_values_ioctl() doesn't stop the perfmon when
capturing the values. All lifecycle management is handled by the
job (for per-job perfmons) or the set_global IOCTL (for global
perfmons).

drm/rockchip: Remove dependency on DRM simple helpers
Simple KMS helper are deprecated since they only add an intermediate layer between drivers and the atomic modesetting. This patch removes the drm_simple_encoder_init() helper usage in the rockchip drivers by open coding it and using the encoder atomic helpers directly. This is a step to eventually get rid of this simple KMS helper, once all drivers that use it have been converted.

drm/sun4i: fix refcount leak in sun4i_backend_init_sat()
When sun4i_backend_init_sat() calls reset_control_deassert() it
increments the deassert_count of the reset controller, and must
pair that with a reset_control_assert() call to decrement it.
In the error path where clk_prepare_enable() fails, the function
returns immediately without calling reset_control_assert(), leaking
the reference count. Other error paths, like the devm_clk_get()
failure, correctly jump to the err_assert_reset label which performs
the missing assert.
Fix the leak by using the existing err_assert_reset label in the
clk_prepare_enable error path instead of returning directly.

drm/ssd130x: fix column and row end address in partial updates in ssd133x
On partial screen updates, SSD133X controllers expect to get the
rectangle addresses as arguments of the "Set Column Address" and "Set
Row Address" commands. Each command expects the start address and end
address of the row/column in absolute format, however the end
addresses were being sent in a relative format (relative to the start
address).
The relative end addresses work only when the start address is 0. In
those situations, there is no value difference between relative and
absolute addresses.

drm/ssd130x: hoist column and row addresses out of repeated division
The ssd132x_update_rect had to calculate the column address twice in the same function by dividing the byte address and the segment_width. Optimize this by hoisting the result into a col variable. Renamed the "y" variable to "row" to match the change made in the x axis.

accel/rocket: Fix error path handling in rocket_job_run()
In rocket_job_run(), after taking an extra fence reference for
job->done_fence via dma_fence_get(), the error paths have three bugs:
- The dma_fence reference held by job->done_fence is never released,
causing a reference leak.
- pm_runtime_get_sync() increments the usage counter even on failure,
but the error path does not decrement it, leaking the runtime PM
reference and preventing the NPU from suspending.
- A valid but unsignaled fence is returned to the DRM scheduler,
which triggers WARN("Fence ... released with pending signals!")
when the scheduler drops its reference.
Fix by replacing pm_runtime_get_sync() with pm_runtime_resume_and_get()
which auto-balances the usage counter on failure, releasing both fence
references on error, and returning ERR_PTR(ret) instead of the
unsignaled fence.

accel/rocket: fix NULL dereference and integer overflow in rocket_job_push()
rocket_job_push() allocates a temporary array to hold all input and
output GEM object pointers:
bos = kvmalloc_array(job->in_bo_count + job->out_bo_count,
sizeof(void *), GFP_KERNEL);
memcpy(bos, job->in_bos, job->in_bo_count * sizeof(void *));
memcpy(&bos[job->in_bo_count], job->out_bos, ...);
Two bugs exist:
1. Missing NULL check: if kvmalloc_array() fails, bos is NULL and
the subsequent memcpy() dereferences it, causing a kernel NULL
pointer dereference.
2. Integer overflow: in_bo_count and out_bo_count are both u32, set
directly from userspace-supplied in_bo_handle_count and
out_bo_handle_count with no prior validation. Their sum is computed
in u32 arithmetic and can wrap to a smaller value, causing the
allocation count passed to kvmalloc_array() to be smaller than
intended. Subsequent uses still operate on the original counts when
copying and locking objects, which may lead to out-of-bounds accesses
on the temporary array.
Fix by using check_add_overflow() to detect count overflow before the
allocation, and adding a NULL check on the allocation result.

accel/rocket: initialize job domain before cleanup paths
rocket_ioctl_submit_job() releases rjob through rocket_job_put() on
allocation error paths. rocket_job_cleanup() unconditionally calls
rocket_iommu_domain_put(job->domain), but job->domain is assigned only
after task copying and BO lookups. A failure before that assignment can
therefore clean up a job with a NULL domain pointer.
Take the per-file domain reference before the first error path can release
rjob. Also clear rjob->tasks after freeing it in rocket_copy_tasks(), so
the common cleanup path cannot free the task array again after a task-copy
error.

ACPI support fixes for 7.2-rc2
- Add a missing ACPI_TAD_AC_WAKE capability check omitted by mistake to
the ACPI TAD driver (Xu Rao)
- Define acpi_ut_safe_strncpy() as an alias for strscpy_pad() which is
viable because that function is only called from kernel code (Rafael

MAINTAINERS: Track dw-hdmi-qp under Rockchip DRM drivers
The DW HDMI QP TX library was developed for and is currently only used by Rockchip platforms. Add it to the Rockchip DRM drivers section to ensure all relevant parties are kept in the loop on any changes. As its file paths fall outside the generic wildcard patterns defined in the ARM/Rockchip SoC support section, also add the linux-rockchip@lists.infradead.org mailing list to avoid any notification gaps.

drm/bridge: analogix_dp: Apply standard DP training delay helpers
Replace hardcoded fixed usleep_range() delays during clock recovery and channel equalization with drm_dp_link_train_clock_recovery_delay() and drm_dp_link_train_channel_eq_delay() helpers. The original fixed delays are only valid for the case where bit[6:0] of DPCD TRAINING_AUX_RD_INTERVAL(0000Eh) is 0x00, while core helpers apply spec-compliant timings matching actual receiver capability values. Additionally, add dpcd buffer to struct analogix_dp_device to cache receiver capabilities. Call drm_dp_read_dpcd_caps() at commit entry to populate cached DPCD data for subsequent link training steps, and prepare for further usage of other DP helper APIs.

Pull vfs fixes from Christian Brauner:
- netfs:
- fix the decision when to disallow write-streaming with fscache in
use, handling of asynchronous cache object creation, a double fput
in cachefiles, clearing S_KERNEL_FILE without the inode lock held,
page extraction bugs in the iov_iter helpers (a potential
underflow, a missing allocation failure check, a memory leak, and
a folio offset miscalculation), writeback error and ENOMEM
handling, DIO write retry for filesystems without a
->prepare_write() method, and the replacement of the wb_lock mutex
with a bit lock plus writethrough collection offload so that
multiple asynchronous writebacks don't interfere with each other.
- Fix the barriering when walking the netfs subrequest list during
retries as it was possible to see a subrequest that was just added
by the application thread.
- iomap:
- Change iomap to submit read bios after each extent instead of
building them up across extents. The old behavior was considered
problematic for a while and now caused an actual erofs bug.
- Guard the ioend io_size EOF trim in iomap against underflow when a
concurrent truncate moves EOF below the start of the ioend,
wrapping io_size to a huge value.
- overlayfs
- Fix a stale overlayfs comment about the locking order.
- Store the linked-in upper dentry instead of the disconnected
O_TMPFILE dentry during overlayfs tmpfile copy-up. With a FUSE or
virtiofs upper layer ->d_revalidate() would try to look up "/" in
the workdir and fail, causing persistent ESTALE errors that broke
dpkg and apt.
- vfs-bpf:
Have the bpf_real_data_inode() kfunc take a struct file instead of a
dentry so it is usable from the bprm_check_security, mmap_file, and
file_mprotect hooks, and rename it from bpf_real_inode() to make the
data-inode semantics explicit. The kfunc landed this cycle so the
change is safe.
- afs:
NULL pointer dereferences in the callback service and in
afs_get_tree(), several memory and refcount leaks, missing locking
around the dynamic root inode numbers and premature cell exposure
through /afs, a netns destruction hang caused by a misplaced
increment of net->cells_outstanding, a bulk lookup malfunction caused
by the dir_emit() API change, inode (re)initialisation issues, and
assorted smaller fixes to error codes, seqlock handling, and debug
output.
- vfs:
Refuse O_TMPFILE creation with an unmapped fsuid or fsgid and add a
selftest for it.
- vboxsf:
Add Jori Koolstra as vboxsf maintainer, taking over from Hans de
Goede.
- dio:
Release the pages attached to a short atomic dio bio; the REQ_ATOMIC
size check error path leaked them.
- procfs:
Only bump the parent directory link count when registering
directories in procfs. Registering regular files inflated the count
and leaked a link on every create and remove cycle.
- minix:
Avoid an unsigned overflow in the minix bitmap block count
calculation that let crafted images with huge inode or zone counts
pass superblock validation and crash the kernel during mount.
- cachefiles:
Fix a double unlock in the cachefiles nomem_d_alloc error path left
over from the start_creating() conversion.
- fat:
Stop fat from reading directory entries past the 0x00
end-of-directory marker. If the trailing on-disk slots aren't
zero-filled the driver surfaced arbitrary garbage as directory
entries.
- freexvfs:
Don't BUG() on unknown typed-extent types in freevxfs, reachable via
ioctl(FIBMAP) on a crafted image; fail with an I/O error instead.
- orangefs:
Keep the readdir entry size 64-bit in orangefs fill_from_part().
Truncating it to __u32 bypassed the bounds check and led to
out-of-bounds reads triggerable by the userspace client.
- xfs:
Fix the error unwind in xfs_open_devices() which released the rt
device file twice and left dangling buftarg pointers behind that were
freed again when the failed mount was torn down.
- exec:
Fix an off-by-one in the comment documenting the maximum binfmt
rewrite depth in exec_binprm(). The code allows five rewrites, not
four; restricting the code would break userspace so the comment is
fixed instead.
- file handles:
Reject detached mounts in capable_wrt_mount(). A detached mount can
be dissolved concurrently, leaving a NULL mount namespace that
open_by_handle_at() would dereference.
