Subject: v3d: take into account prim_counts_offset
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=fa41a51891e5a207da831fa7c4564a413159f221;p=mesa.git

v3d: take into account prim_counts_offset

Specifically when reading the primitive counters.

This fixed ~700 CTS tests using this pattern:
dEQP-GLES3.functional.transform_feedback.*

when run after tests like
dEQP-GLES3.functional.prerequisite.read_pixels on the same
caselist. When run individually those tests were passing because
prim_counts_offset was zero.

Fixes: 0f2d1dfe65bfe1ee8f02ce45f100a5508debdfd4 ("v3d: use the GPU to
       record primitives written to transform feedback")
