Merge tag 'drm-xe-next-2026-04-30' of https://gitlab.freedesktop.org/drm/xe/kernel into drm-next
UAPI Changes:
- Debugfs multi-LRC engine info (Xin Wang, 2 commits)
Expose multi-LRC engine classe
Merge tag 'drm-xe-next-2026-04-30' of https://gitlab.freedesktop.org/drm/xe/kernel into drm-next
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.
