observe the effective bandwidth ceiling.
[How]
Rename struct memory_qos to dc_measured_memory_qos and introduce
a new struct dc_requested_memory_qos holding bandwidth lower bound,
calculated average bandwidth, latency upper bounds, and max bandwidth
budget. Add a get_requested_memory_qos function pointer to
clk_mgr_funcs. Update dc_get_qos_info to call through the new

GART TLB is flushed after unmapping but not after mapping. Since
amdgpu_bo_create_kernel() does not zero-initialize the buffer, when a
single PTE is written the TLB may speculatively load other uninitialized
entries from the same cacheline. Those garbage entries can appear valid,
and a subsequent write to another PTE in the same cacheline may cause the
GPU to use a stale garbage PTE from the TLB.
Fix this by calling memset_io() to zero-initialize the GART table with

UAPI Changes:
- Debugfs multi-LRC engine info (Xin Wang, 2 commits)
Expose multi-LRC engine classes in the debugfs engine info output
and improve the output readability.
- drm/drm_ras: Add clear-error-counter netlink command to drm_ras
Cross-subsystem Changes:
Core Changes:
- drm/gpusvm: Reject VMAs with VM_IO or VM_PFNMAP when creating SVM ranges
- drm/i915/display: switch to including common step file directly
Driver Changes:
- Engine initialization cleanup (Matt Roper, 10 commits)
Clean up engine initialization code inherited from i915 by moving
hardware programming (CCS enablement, HWSTAM, GFX_MODE, BLIT_CCTL,
STOP_RING) into the RTP infrastructure. This makes the programming
visible and verifiable via debugfs, and applies consistently across
both normal and execlist init paths. Also fixes the name/definition
of GFX_MODE, marks BCS engines as belonging to the GT forcewake
domain, and drops the now-unused xe_hw_engine_mmio_write32() helper.
- PF fair scheduling auto-provisioning (Michal Wajdeczko, 13 commits)
Fix several corner cases in SR-IOV PF scheduling policy provisioning,
then auto-provision PF and all VFs with 16ms execution-quantum and
preemption-timeout defaults. This prevents a VF from monopolizing
the GPU by submitting workloads without gaps, without requiring the
user to configure sysfs manually.
- System Controller support for CRI/Xe3p (Anoop Vijay + Raag Jadav, 10 commits)
Add xe_sysctrl infrastructure for communicating with the System
Controller firmware entity on CRI/Xe3p discrete GPU platforms via a
mailbox interface. Includes type definitions, register definitions,
mailbox communication, initialization, power management, interrupt
handling, and event dispatch. Builds on this to add initial RAS
correctable error handling, using sysctrl interrupts to receive
threshold-crossed events.
- PXP state machine fixes (Daniele Ceraolo Spurio, 4 commits)
Fix PXP state machine handling: reject PXP sessions on PTL platforms
with older GSC firmware that does not support it, fix the restart
flag not being cleared after jumping back in pxp_start, remove
incorrect handling of an impossible state during suspend, and clean
up termination status on failure.
- Reset/wedge/unload corner case fixes (Zhanjun Dong + Matthew Brost, 5 commits)
Fix memory leaks and fence signal failures that occurred during GPU
reset, device wedging, and driver unload by forcefully tearing down
remaining exec queues in GuC submit fini, always killing queues in
pause/abort, and triggering queue cleanup when not in wedged mode 2.
Also ensures GuC CT state transitions via STOP before DISABLED.
- Wedge path memory allocation fixes (Matthew Brost, 3 commits)
Avoid GFP_KERNEL allocations in xe_device_declare_wedged(), which
runs in the DMA-fence signaling path. Also drops the
guc_submit_wedged_fini devm registration from xe_guc_submit_wedge()
to clean up the wedge shutdown sequence.
- PAT type cleanup and invalid index hardening (Xin Wang, 3 commits)
Standardize pat_index fields to u16 across the driver, default
XE_CACHE_NONE_COMPRESSION to XE_PAT_INVALID_IDX (matching
WB_COMPRESSION), and introduce xe_cache_pat_idx() — a macro helper
that validates cache_mode bounds and asserts on invalid PAT indices
before returning the index.
- Reject unsafe PAT indices for CPU cached memory (Jia Yao, 2 commits)
Reject incoherent (coh_none) PAT indices for CPU cached memory in
both the madvise ioctl and vm_bind with CPU_ADDR_MIRROR flag, closing
a security gap where the GPU could bypass CPU caches and observe
stale or sensitive data.
- OA improvements for CRI device memory (Ashutosh Dixit, 3 commits)
Move OA buffer access to the xe_map layer to support both system and
device memory (required for CRI), switch OA buffer mmap to use
drm_gem_mmap_obj, and implement workaround Wa_14026633728.
- xe_drm.h documentation fixes (Shuicheng Lin, 6 commits)
Fix multiple documentation issues in the xe_drm.h UAPI header:
typos, spelling errors, grammar, wrong names and references,
kernel-doc cross-reference syntax, and broken code examples.
- kernel-doc syntax fixes in xe headers (Shuicheng Lin, 4 commits)
Fix kernel-doc syntax issues across xe header files: missing '@'
prefixes on member tags, stale/mismatched member tags, comment
syntax errors, and type/parameter name mismatches in references.
- Buffer object and DMA-buf resource leak fixes (Shuicheng Lin, 4 commits)
Fix resource leaks on error paths: DMA-buf attachment leak in
xe_gem_prime_import(), BO leak in xe_dma_buf_init_obj() on
allocation failure, and BO leaks in xe_bo_init_locked() on GGTT
flag validation and unaligned size validation failures.
- Include guard cleanup (Shuicheng Lin, 5 commits)
Fix and standardize include guards across xe header files: normalize
double-underscore guards to single, add missing leading/trailing
underscores, add missing _H suffixes, and add guards to previously
unprotected headers.
- VF CCS memory pool (Satyanarayana K V P, 2 commits)
Switch VF CCS read/write operations from the DRM sub-allocator to
DRM mm, fixing allocation failures in fence-disabled mode where
the sub-allocator's hole cursor assumption breaks. Also introduces
a general BO-backed memory pool with shadow support using drm_mm.
- i915/xe step definition unification (Jani Nikula, 3 commits)
Complete the migration to the shared intel_step header: switch xe
from its own xe_step enum to the shared intel_step naming and
definitions, and update i915 display code to include the common
step header directly.
- Xe3p GT tuning fixes (3 commits)
Three Xe3p GT tuning corrections: fix the register offset for
GAMSTLB_CTRL, stop applying the CCCHKNREG1 tuning from Xe3p onward
(no longer needed), and mark ROW_CHICKEN5 as a masked register.
- Forcewake cleanup in GT and GuC PC (Raag Jadav, 3 commits)
Drop a redundant forcewake reference in xe_gt, reorder forcewake
usage in xe_guc_pc_fini_hw() to avoid a redundant hold, and convert
xe_guc_pc_stop() to void since it can no longer fail.
- SVM garbage collector fix on close (Matthew Brost, 2 commits)
Disable the SVM garbage collector work item when an SVM is closed
to prevent use-after-free when the GC fires after the SVM is freed.
- Admin-only PF mode (Satyanarayana K V P, 2 commits)
Derive an "admin-only PF" mode flag from xe_device state instead of
using a local flag, and restrict device query responses when running
in admin-only PF mode to avoid exposing internal state.
- Enable hwmon energy attributes and accepted power limit for CRI (2 commits)
Enable energy consumption hwmon attributes for the CRI platform and
add support for reading the accepted (sustained) power limit via
hwmon.

drm/i915/display: Avoid stale PIPE_SCANLINE values after crtc_enable
When a CRTC is moved to a different transcoder (e.g. on DP-MST stream
allocation), PIPE_SCANLINE and PIPE_FRMCNT can return values latched
from the previous transcoder/mode for up to one vblank period after
the new pipe is enabled. The vblank evasion code in
intel_pipe_update_start()/end() then samples a stale or boundary
scanline and the frame counter ticks during the critical section,
producing diagnostic errors of the form:
[243.348405] xe 0000:00:02.0: [drm] *ERROR* Atomic update failure on
pipe B (start=300 end=301) time 61 us, min 2128, max 2161, scanline
start 1200, end 2165
[248.536260] xe 0000:00:02.0: [drm] *ERROR* Atomic update failure on
pipe B (start=561 end=562) time 61 us, min 2128, max 2161, scanline
start 2162, end 2167
Here "scanline start 1200" is the vblank_start of a previously
programmed mode on a different transcoder, while "2162" is the current
mode's vblank_start sampled before any real frame has been emitted.
Both indicate a stale read rather than a real evasion miss.
Wait for one vblank after crtc_enable() to give the new transcoder a
chance to start producing live PIPE_SCANLINE/FRMCNT values before any
subsequent atomic commit enters the vblank evasion section. This adds
at most one frame of latency on modeset, which is invisible to users.
Reproduced with igt@kms_rotation_crc@sprite-rotation-180 on a DP-MST
sink; with this patch the failures no longer occur.

drm: Rename struct drm_atomic_state to drm_atomic_commit
The KMS framework uses two slightly different definitions for the state
concept. For a given object (plane, CRTC, encoder, etc., so
drm_$OBJECT_state), the state is the entire state of that object.
However, at the device level, drm_atomic_state refers to a state update
for a limited number of objects.
Thus, drm_atomic_state isn't the entire device state, but only the full
state of some objects in that device. This has been an endless source of
confusion and thus bugs.
We can rename the drm_atomic_state structure to drm_atomic_commit to
make it less confusing.
This patch was created using:
rg -l drm_atomic_state | \
xargs sed -i 's/drm_atomic_state/drm_atomic_commit/g; s/drm_atomic_commit_helper/drm_atomic_state_helper/g'

arm64: signal: Preserve POR_EL0 if poe_context is missing
Commit
2e8a1acea859 ("arm64: signal: Improve POR_EL0 handling to
avoid uaccess failures") delayed the write to POR_EL0 in
rt_sigreturn to avoid spurious uaccess failures. This change however
relies on the poe_context frame record being present: on a system
supporting POE, calling sigreturn without a poe_context record now
results in writing arbitrary data from the kernel stack into POR_EL0.
Fix this by adding a __valid_fields member to struct
user_access_state, and zeroing the struct on allocation.
restore_poe_context() then indicates that the por_el0 field is valid
by setting the corresponding bit in __valid_fields, and
restore_user_access_state() only touches POR_EL0 if there is a valid
value to set it to. This is in line with how POR_EL0 was originally
handled; all frame records are currently optional, except
fpsimd_context.
To ensure that __valid_fields is kept in sync, fields (currently
just por_el0) are now accessed via accessors and prefixed with __ to
discourage direct access.

For 4K pages, the early kernel mapping may use 2MB block entries but the
kernel segments are only 64KB aligned. Segment boundaries that fall
within a 2MB block therefore require a PTE table so that different
attributes can be applied on either side of the boundary.
KERNEL_SEGMENT_COUNT still correctly counts the five permanent kernel
VMAs registered by declare_kernel_vmas(). However, since commit
5973a62efa34 ("arm64: map [_text, _stext) virtual address range
non-executable+read-only"), the early mapper also maps [_text, _stext)
separately from [_stext, _etext). This adds one more early-only split
and can require one more page-table page than the existing
EARLY_SEGMENT_EXTRA_PAGES allowance reserves.
Increase the 4K-page early mapping allowance by one page to cover that
additional split.

mm: memcontrol: fix rcu unbalance in get_non_dying_memcg_end()
Currently, get_non_dying_memcg_start() and get_non_dying_memcg_end() both
evaluate cgroup_subsys_on_dfl(memory_cgrp_subsys) independently to
determine whether to acquire or release the RCU read lock.
However, the result of cgroup_subsys_on_dfl() can change dynamically at
runtime due to cgroup hierarchy rebinding (e.g., when the memory
controller is moved between cgroup v1 and v2 hierarchies). This can cause
the following warning:
=====================================

Fix this by explicitly tracking the RCU lock state, ensuring that
rcu_read_unlock() in get_non_dying_memcg_end() is strictly paired with the
lock acquisition, regardless of any runtime rebinding events.

io_uring/tw: serialize ctx->retry_llist with ->uring_lock
The DEFER_TASKRUN local task work paths all run under ctx->uring_lock,
which serializes them with each other and with the rest of the ring's
hot paths. io_move_task_work_from_local() is the exception - it's called
from io_ring_exit_work() on a kworker without holding the lock and from
the iopoll cancelation side right after dropping it.
->work_llist is fine with this, as it's only ever updated via the
expected paths. But the ->retry_llist is updated while runing, and hence
it could potentially race between normal task_work running and the
task-has-exited shutdown path.
Simply grab ->uring_lock while moving the local work to the fallback
list for exit purposes, which nicely serializes it across both the
normal additions and the exit prune path.
