Subject: nv50: don't flush vertex arrays when index buffer changes
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=4a025c6bc835387a31007fdf30a130e612e54e19;p=mesa.git

nv50: don't flush vertex arrays when index buffer changes

The index buffer is fed in inline over a pushbuf. It's not related to
vertices or any caching that might be done on them.
