drm/msm/gem: Evict active GEM objects when necessaryIf we are under enough memory pressure, we should stall waiting foractive buffers to become idle in order to evict.v2: Check for __GFP_ATOMIC before blockingSigned-off-by: Rob Clark Patchwork: https://patchwork.freedesktop.org/patch/496135/Link: https://lore.kernel.org/r/20220802155152.1727594-14-robdclark@gmail.com List of files: /linux-6.15/drivers/gpu/drm/msm/msm_gpu_trace.h

drm/msm/gem: Consolidate shrinker traceCombine separate trace events for purge vs evict into one. When we addsupport for purging/evicting active buffers we'll just add more infointo this one trace event, rather than adding a bunch more events.Signed-off-by: Rob Clark Patchwork: https://patchwork.freedesktop.org/patch/496133/Link: https://lore.kernel.org/r/20220802155152.1727594-13-robdclark@gmail.com List of files: /linux-6.15/drivers/gpu/drm/msm/msm_gpu_trace.h

drm/msm: Support evicting GEM objects to swapNow that tracking is wired up for potentially evictable GEM objects,wire up shrinker and the remaining GEM bits for unpinning backing pagesof inactive objects.Disabled by default for now, with an 'enable_eviction' module param toenable so that we can get some more testing on the range of generations(and iommu pairings) supported.Signed-off-by: Rob Clark Link: https://lore.kernel.org/r/20210405174532.1441497-9-robdclark@gmail.comSigned-off-by: Rob Clark List of files: /linux-6.15/drivers/gpu/drm/msm/msm_gpu_trace.h

drm/msm/gpu: Add trace events for tracking GPU submissionsAdd trace events to track the progress of a GPU submissionmsm_gpu_submit occurs at the beginning of the submissions,msm_gpu_submit_flush happens when the submission is put onthe ringbuffer and msm_submit_flush_retired is sent whenthe operation is retired.To make it easier to track the operations a unique sequencenumber is assigned to each submission and displayed in eachevent output so a human or a script can easily associatethe events related to a specific submission.Signed-off-by: Jordan Crouse Signed-off-by: Rob Clark List of files: /linux-6.15/drivers/gpu/drm/msm/msm_gpu_trace.h
