[Intel-gfx] [PATCH 1/2] drm/i915/gt: Prefer recycling an idle fence

[Intel-gfx] [PATCH 1/2] drm/i915/gt: Prefer recycling an idle fence

[Chris Wilson]

If we want to reuse a fence that is in active use by the GPU, we have to
wait an uncertain amount of time, but if we reuse an inactive fence, we
can change it right away. Loop through the list of available fences
twice, ignoring any active fences on the first pass.

[Intel-gfx] [PATCH 2/2] drm/i915/gem: Optimistically prune dma-resv from the shrinker.

[Chris Wilson]

As we shrink an object, also see if we can prune the dma-resv of idle
fences it is maintaining a reference to.
