Subject: freedreno: fix stream-out offset handling for lines/tris
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7e93b26b5d9f926346fb3651c0094fc1caade4d8;p=mesa.git

freedreno: fix stream-out offset handling for lines/tris

We need to increment offset by # of vertices, not by # of prims.  Fixes
a bunch of dEQP fails involving prims other than points.  For example,
dEQP-GLES3.functional.transform_feedback.position.lines_separate
