drm/xe: Invalidate userptr VMA on page pin fault Rather than return an error to the user or ban the VM when userptr VMA page pin fails with -EFAULT, invalidate VMA mappings. This supports the UMD use case of freeing userptr while still having bindings. Now that non-faulting VMs can invalidate VMAs, drop the usm prefix for the tile_invalidated member. v2: - Fix build error (CI) v3: - Don't invalidate VMA if in fault mode, rather kill VM (Thomas) - Update commit message with tile_invalidated name chagne (Thomas) - Wait VM bookkeep slots with VM resv lock (Thomas) v4: - Move list_del_init(&userptr.repin_link) after error check (Thomas) - Assert not in fault mode (Matthew) Fixes: dd08ebf6c352 ("drm/xe: Introduce a new DRM driver for Intel GPUs") Signed-off-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Thomas Hellström <thomas.hellstrom@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240312183907.933835-1-matthew.brost@intel.com (cherry picked from commit 521db22a1d70dbc596a07544a738416025b1b63c) Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com>

drm/xe: Use pointers in trace events Commit a0df2cc858c3 ("drm/xe/xe_bo_move: Enhance xe_bo_move trace") inadvertently reverted commit 8d038f49c1f3 ("drm/xe: Fix cast on trace variable"), breaking the build on 32bits. As noted by Ville, there's no point in converting the pointers to u64 and add casts everywhere. In fact, it's better to just use %p and let the address be hashed. Convert all the cases in xe_trace.h to use pointers.

drm/xe: Long running job update For long running (LR) jobs with the DRM scheduler we must return NULL in run_job which results in signaling the job's finished fence immediately. This prevents LR jobs from creating infinite dma-fences. Signaling job's finished fence immediately breaks flow controlling ring with the DRM scheduler. To work around this, the ring is flow controlled and written in the exec IOCTL. Signaling job's finished fence immediately also breaks the TDR which is used in reset / cleanup entity paths so write a new path for LR entities. v2: Better commit, white space, remove rmb(), better comment next to emit_job() v3 (Thomas): Change LR reference counting, fix working in commit Reviewed-by: Thomas Hellström <thomas.hellstrom@linux.intel.com> Signed-off-by: Matthew Brost <matthew.brost@intel.com> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>

drm/xe: Introduce a new DRM driver for Intel GPUs Xe, is a new driver for Intel GPUs that supports both integrated and discrete platforms starting with Tiger Lake (first Intel Xe Architecture). The code is at a stage where it is already functional and has experimental support for multiple platforms starting from Tiger Lake, with initial support implemented in Mesa (for Iris and Anv, our OpenGL and Vulkan drivers), as well as in NEO (for OpenCL and Level0). The new Xe driver leverages a lot from i915. As for display, the intent is to share the display code with the i915 driver so that there is maximum reuse there. But it is not added in this patch. This initial work is a collaboration of many people and unfortunately the big squashed patch won't fully honor the proper credits. But let's get some git quick stats so we can at least try to preserve some of the credits: Co-developed-by: Matthew Brost <matthew.brost@intel.com> Co-developed-by: Matthew Auld <matthew.auld@intel.com> Co-developed-by: Matt Roper <matthew.d.roper@intel.com> Co-developed-by: Thomas Hellström <thomas.hellstrom@linux.intel.com> Co-developed-by: Francois Dugast <francois.dugast@intel.com> Co-developed-by: Lucas De Marchi <lucas.demarchi@intel.com> Co-developed-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Co-developed-by: Philippe Lecluse <philippe.lecluse@intel.com> Co-developed-by: Nirmoy Das <nirmoy.das@intel.com> Co-developed-by: Jani Nikula <jani.nikula@intel.com> Co-developed-by: José Roberto de Souza <jose.souza@intel.com> Co-developed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Co-developed-by: Dave Airlie <airlied@redhat.com> Co-developed-by: Faith Ekstrand <faith.ekstrand@collabora.com> Co-developed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Co-developed-by: Mauro Carvalho Chehab <mchehab@kernel.org> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Matthew Brost <matthew.brost@intel.com>
