2024-04-09drm/xe/xe2hpg: Remove extra allocation of CCS pages for dgfxAkshata Jahagirdar
On Xe2 dGPU, compression is only supported with VRAM. When copying from VRAM -> system memory the KMD uses mapping with uncompressed PAT so the copy in system memory is guaranteed to be uncompressed. When restoring such buffers from system memory -> VRAM the KMD can't easily know which pages were originally compressed, so we always use uncompressed -> uncompressed here. so this means that there's no need for extra CCS storage on such platforms. v2: More description added to commit message Signed-off-by: Akshata Jahagirdar <akshata.jahagirdar@intel.com> Signed-off-by: Balasubramani Vivekanandan <balasubramani.vivekanandan@intel.com> Reviewed-by: Himal Prasad Ghimiray <himal.prasad.ghimiray@intel.com> Reviewed-by: Matt Roper <matthew.d.roper@intel.com> Signed-off-by: Matt Roper <matthew.d.roper@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240408170545.3769566-8-balasubramani.vivekanandan@intel.com

2024-04-09nouveau: fix devinit paths to only handle display on GSP.Dave Airlie
This reverts: nouveau/gsp: don't check devinit disable on GSP. and applies a further fix. It turns out the open gpu driver, checks this register, but only for display. Match that behaviour and in the turing path only disable the display block. (ampere already only does displays). Fixes: 5d4e8ae6e57b ("nouveau/gsp: don't check devinit disable on GSP.")

2024-04-08drm/xe: Always capture exec queues on snapshotMatthew Brost
Always capture exec queues on snapshot regardless if exec queue has pending jobs or not. Having jobs or not does indicate whether the exec queue capture is useful. Example bugs that would not be easily detected by skipping capture when pending job list is empty: - Jobs pending on exec queue have dependencies - Leaking exec queue refs - GuC protocol issues (i.e. losing G2H) In addition to above bugs, in general it just useful to see every exec queue registered with the GuC and its state.

2024-04-08drm/xe/uapi: Restore flags VM_BIND_FLAG_READONLY and VM_BIND_FLAG_IMMEDIATEFrancois Dugast
The commit 84a1ed5e6756 ("drm/xe/uapi: Remove unused flags") is partially reverted. At the time, flags not used by user space were removed during cleanup. Some flags now needed by the compute runtime are brought back in this commit: - DRM_XE_VM_BIND_FLAG_READONLY is used to write protect kernel ISA thus preventing accidental overwrites. - DRM_XE_VM_BIND_FLAG_IMMEDIATE is used to trigger mapping at the time of binding in order to prevent faulting at execution time. The changes in the compute runtime are ready and approved, see link below. v2: Include a link to the PR in the commit message (Matthew Brost) v3: Update kernel doc and improve commit message (Lucas De Marchi) Cc: Mateusz Jablonski <mateusz.jablonski@intel.com> Cc: Michal Mrozek <michal.mrozek@intel.com> Cc: Matthew Brost <matthew.brost@intel.com> Cc: Lucas De Marchi <lucas.demarchi@intel.com> Link: https://github.com/intel/compute-runtime/pull/717 Signed-off-by: Francois Dugast <francois.dugast@intel.com> Reviewed-by: Matthew Brost <matthew.brost@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240329124403.7-1-francois.dugast@intel.com Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com>

2024-04-08drm/i915/guc: Fix the fix for reset lock confusionJohn Harrison
The previous fix for the circlular lock splat about the busyness worker wasn't quite complete. Even though the reset-in-progress flag is cleared at the start of intel_uc_reset_finish, the entire function is still inside the reset mutex lock. Not sure why the patch appeared to fix the issue both locally and in CI. However, it is now back again. There is a further complication that the wedge code path within intel_gt_reset() jumps around so much that it results in nested reset_prepare/_finish calls. That is, the call sequence is: intel_gt_reset | reset_prepare | __intel_gt_set_wedged | | reset_prepare | | reset_finish | reset_finish The nested finish means that even if the clear of the in-progress flag was moved to the end of _finish, it would still be clear for the entire second call. Surprisingly, this does not seem to be causing any other problems at present. As an aside, a wedge on fini does not call the finish functions at all. The reset_in_progress flag is left set (twice). So instead of trying to cancel the worker anywhere at all in the reset path, just add a cancel to intel_guc_submission_fini instead. Note that it is not a problem if the worker is still active during a reset. Either it will run before the reset path starts locking things and will simply block the reset code for a tiny amount of time. Or it will run after the locks have been acquired and will early exit due to the try-lock. Also, do not use the reset-in-progress flag to decide whether a synchronous cancel is safe (from a lockdep perspective) or not. Instead, use the actual reset mutex state (both the genuine one and the custom rolled BACKOFF one).
