2019-05-22drm: Replace drm_gem_vram_push_to_system() with kunmap + unpinThomas Zimmermann
The push-to-system function forces a buffer out of video RAM. This decision should rather be made by the memory manager. By replacing the function with calls to the kunmap and unpin functions, the buffer's memory becomes available, but the buffer remains in VRAM until it's evicted by a pin operation.

2019-05-21drm/lima: add timeout to drm scheduler initErico Nunes
After "5918045c4ed4 drm/scheduler: rework job destruction", lima started to leak memory due to buffers not being destroyed after job execution in the drm scheduler. This started happening because the drm scheduler only destroyed buffers after cancelling the job timeout handler, and for lima this handler was never started as lima specified a MAX_SCHEDULE_TIMEOUT timeout. Lima seems to run well in its current state with a real timeout, so to make it more aligned with the other drivers from now on, let's use a real default timeout. This also fixes the observed memory leaks. The 500ms value was chosen as it is the current value for all other embedded gpu drivers using drm sched.

drm_format_horz_chroma_subsampling and drm_format_vert_chroma_subsampling are basically a lookup in the drm_format_info table plus an access to the hsub and vsub fields of the appropriate entry. Most drivers are using this function while having access to the entry already, which means that we will perform an unnecessary lookup. Removing the call to these functions is therefore more efficient. Some drivers will not have access to that entry in the function, but in this case the overhead is minimal (we just have to call drm_format_info() to perform the lookup) and we can even avoid multiple, inefficient lookups in some places that need multiple fields from the drm_format_info structure. This is amplified by the fact that most of the time the callers will have to retrieve both the vsub and hsub fields, meaning that they would perform twice the lookup.

We can already do this with --per-core, but it's often useful to do this together with other metrics that are collected per hardware thread.
