I will let them soak in drm-xe-next for more time before sending another pull. Plan is to send an early pull next week that should contain these. thanks Lucas De Marchi > >Lucas De Marchi
Hi Dave and Sima, Last drm-xe-next pull request for 6.15. It comes with some big features that we have been working on for some time: EU stall sampling and SVM. The latter also touches other subsystems and provides the common parts in the drm layer. Low latency hints from userspace to improve some workloads and more events exposed via perf complete the UAPI changes for this cycle. Another cross-subsystem change is to drivers/base to improve devres handling. Fixes, workarounds and refactors also made their appearance as usual. Worth noting 2 conflicts reported by Stephen on linux-next. One is a git conflict and the other is on build: https://lore.kernel.org/intel-xe/20250307122954.1ab65809@canb.auug.org.au/ and https://lore.kernel.org/intel-xe/20250307132112.18b6ce90@canb.auug.org.au/ These will probably show up when Linus merges drm. I checked the fixes on linux-next by Stephen and they look good to me. thanks Lucas De Marchi drm-xe-next-2025-03-07: UAPI Changes: - Expose per-engine activity via perf pmu (Riana, Lucas, Umesh) - Add support for EU stall sampling (Harish, Ashutosh) - Allow userspace to provide low latency hint for submission (Tejas) - GPU SVM and Xe SVM implementation (Matthew Brost) Cross-subsystem Changes: - devres handling for component drivers (Lucas) - Backmege drm-next to allow cross dependent change with i915 - GPU SVM and Xe SVM implementation (Matthew Brost) Core Changes: Driver Changes: - Fixes to userptr and missing validations (Matthew Auld, Thomas Hellström, Matthew Brost) - devcoredump typos and error handling improvement (Shuicheng) - Allow oa_exponent value of 0 (Umesh) - Finish moving device probe to devm (Lucas) - Fix race between submission restart and scheduled being freed (Tejas) - Fix counter overflows in gt_stats (Francois) - Refactor and add missing workarounds and tunings for pre-Xe2 platforms (Aradhya, Tvrtko) - Fix PXP locks interaction with exec queues being killed (Daniele) - Eliminate TIMESTAMP_OVERRIDE from xe (Matt Roper) - Change xe_gen_wa_oob to allow building on MacOS (Daniel Gomez) - New workarounds for Panther Lake (Tejas) - Fix VF resume errors (Satyanarayana) - Fix workaround infra skipping some workarounds dependent on engine initialization (Tvrtko) - Improve per-IP descriptors (Gustavo) - Add more error injections to probe sequence (Francois) The following changes since commit 33e26f3544a558e7476eb221ff33173759b3a116: Merge tag 'drm-xe-next-2025-02-24' of https://gitlab.freedesktop.org/drm/xe/kernel into drm-next (2025-02-27 10:08:29 +1000) are available in the Git repository at: https://gitlab.freedesktop.org/drm/xe/kernel.git tags/drm-xe-next-2025-03-07 for you to fetch changes up to 45f5a1efac90214d9593afb0a900a2c73e1fc95b: drm/doc: gpusvm: Add GPU SVM documentation (2025-03-06 11:38:21 -0800) ---------------------------------------------------------------- UAPI Changes: - Expose per-engine activity via perf pmu (Riana, Lucas, Umesh) - Add support for EU stall sampling (Harish, Ashutosh) - Allow userspace to provide low latency hint for submission (Tejas) - GPU SVM and Xe SVM implementation (Matthew Brost) Cross-subsystem Changes: - devres handling for component drivers (Lucas) - Backmege drm-next to allow cross dependent change with i915 - GPU SVM and Xe SVM implementation (Matthew Brost) Core Changes: Driver Changes: - Fixes to userptr and missing validations (Matthew Auld, Thomas Hellström, Matthew Brost) - devcoredump typos and error handling improvement (Shuicheng) - Allow oa_exponent value of 0 (Umesh) - Finish moving device probe to devm (Lucas) - Fix race between submission restart and scheduled being freed (Tejas) - Fix counter overflows in gt_stats (Francois) - Refactor and add missing workarounds and tunings for pre-Xe2 platforms (Aradhya, Tvrtko) - Fix PXP locks interaction with exec queues being killed (Daniele) - Eliminate TIMESTAMP_OVERRIDE from xe (Matt Roper) - Change xe_gen_wa_oob to allow building on MacOS (Daniel Gomez) - New workarounds for Panther Lake (Tejas) - Fix VF resume errors (Satyanarayana) - Fix workaround infra skipping some workarounds dependent on engine initialization (Tvrtko) - Improve per-IP descriptors (Gustavo) - Add more error injections to probe sequence (Francois) ---------------------------------------------------------------- Aradhya Bhatia (2): drm/xe: Add Wa_16021333562 and Wa_14016712196 drm/xe/oa: Refactor WAs to use XE_WA() macro Colin Ian King (1): drm/xe: Fix uninitialized pointer def Daniel Gomez (1): drm/xe: xe_gen_wa_oob: replace program_invocation_short_name Daniele Ceraolo Spurio (1): drm/xe/pxp: Don't kill queues while holding PXP locks Francois Dugast (3): drm/xe/gt_stats: Use atomic64_t for counters drm/xe/gt_pagefault: Change vma_pagefault unit to kilobyte drm/xe: Allow fault injection in exec queue IOCTLs Gustavo Sousa (7): drm/xe: Set IP names in functions handling IP version drm/xe: Disambiguate GMDID-based IP names drm/xe: Rename gmdid_map to xe_ip drm/xe: Define xe_ip instances before xe_device_desc drm/xe: Convert pre-GMDID IPs to struct xe_ip drm/xe: Re-use feature descriptors for pre-GMDID IPs drm/xe: Simplify setting release info in xe->info Harish Chegondi (8): drm/xe/topology: Add a function to find the index of the last enabled DSS in a mask drm/xe/uapi: Introduce API for EU stall sampling drm/xe/eustall: Add support to init, enable and disable EU stall sampling drm/xe/eustall: Add support to read() and poll() EU stall data drm/xe/eustall: Add support to handle dropped EU stall data drm/xe/eustall: Add EU stall sampling support for Xe2 drm/xe/uapi: Add a device query to get EU stall sampling information drm/xe/eustall: Add workaround 22016596838 which applies to PVC.
