2022-05-26drm/amdgpu: Convert to common fdinfo format v5Christian König1-32/+25
Convert fdinfo format to one documented in drm-usage-stats.rst. It turned out that the existing implementation was actually completely nonsense. The calculated percentages indeed represented the usage of the engine, but with varying time slices. So 10% usage for application A could mean something completely different than 10% usage for application B. Completely nuke that and just use the now standardized nanosecond interface. v2: drop the documentation change for now, nuke percentage calculation v3: only account for each hw_ip, move the time_spend to the ctx mgr. v4: move general ctx changes into separate patch, rework the fdinfo to ctx_mgr interface so that all usages are calculated at once, drop some unecessary and dangerous refcount dance. v5: add one more comment how we calculate the time spend Signed-off-by: Tvrtko Ursulin <[email protected]> Signed-off-by: Christian König <[email protected]> Reviewed-by: Shashank Sharma <[email protected]> Cc: Daniel Vetter <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
