-Subject: [PATCH] drm/vc4: Fulfill user BO creation requests from the kernel BO
- cache.
-
-The from_cache flag was actually "the BO is invisible to userspace",
-so we can repurpose to just zero out a cached BO and return it to
-userspace.
-
-Improves wall time for a loop of 5 glsl-algebraic-add-add-1 by
--1.44989% +/- 0.862891% (n=28, 1 outlier removed from each that
-appeared to be other system noise)
-
-Note that there's an intel-gpu-tools test to check for the proper
-zeroing behavior here, which we continue to pass.
