Subject: broadcom/vc5: Fix pausing of transform feedback.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=80da60947b65b792edc95671147b00bfe53f9101;p=mesa.git

broadcom/vc5: Fix pausing of transform feedback.

Gallium disables it by removing the streamout buffers, not by binding a
program that doesn't have TF outputs.  Fixes piglit
"ext_transform_feedback2/counting with pause"
