Subject: v3d: Disable PIPE_CAP_BLIT_BASED_TEXTURE_TRANSFER.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ccce9409470c1053c40c822d759b9bd417062bc0;p=mesa.git

v3d: Disable PIPE_CAP_BLIT_BASED_TEXTURE_TRANSFER.

This reduces the runtime of dEQP-GLES3.functional.shaders.precision.* from
11.5s to 3.3s.  This brings CTS runs down to 4 hours on one of my target
devices.
