From: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxx> Second try, this time actually per client! :) I added tracking of most classes of objects which contribute to clients memory footprint and accouting along the similar lines as in Rob's msm code. Then printing it out to fdinfo using the drm helper Rob added. Example fdinfo with the series applied: # cat /proc/1383/fdinfo/8 pos: 0 flags: 02100002 mnt_id: 21 ino: 397 drm-driver: i915 drm-client-id: 18 drm-pdev: 0000:00:02.0 drm-total-system: 125 MiB drm-shared-system: 16 MiB drm-active-system: 110 MiB drm-resident-system: 125 MiB drm-purgeable-system: 2 MiB drm-total-stolen-system: 0 drm-shared-stolen-system: 0 drm-active-stolen-system: 0 drm-resident-stolen-system: 0 drm-purgeable-stolen-system: 0 drm-engine-render: 25662044495 ns drm-engine-copy: 0 ns drm-engine-video: 0 ns drm-engine-video-enhance: 0 ns Tvrtko Ursulin (5): drm/i915: Track buffer objects belonging to clients drm/i915: Record which clients own a VM drm/i915: Track page table backing store usage drm/i915: Account ring buffer and context state storage drm/i915: Implement fdinfo memory stats printing drivers/gpu/drm/i915/gem/i915_gem_context.c | 17 ++- .../gpu/drm/i915/gem/i915_gem_context_types.h | 3 + drivers/gpu/drm/i915/gem/i915_gem_create.c | 32 ++++- drivers/gpu/drm/i915/gem/i915_gem_object.c | 6 + .../gpu/drm/i915/gem/i915_gem_object_types.h | 12 ++ drivers/gpu/drm/i915/gt/intel_gtt.c | 6 + drivers/gpu/drm/i915/gt/intel_gtt.h | 1 + drivers/gpu/drm/i915/i915_drm_client.c | 110 +++++++++++++++++- drivers/gpu/drm/i915/i915_drm_client.h | 46 +++++++- drivers/gpu/drm/i915/i915_gem.c | 2 +- 10 files changed, 226 insertions(+), 9 deletions(-) -- 2.39.2
