Subject: nv30/draw: draw expects constbuf size in bytes, not vec4 units
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=147816375d22a653176ab28ed650fa811ceea83f;p=mesa.git

nv30/draw: draw expects constbuf size in bytes, not vec4 units

This fixes glxgears with NV30_SWTNL=1 forced on. Probably fixes a bunch
of other situations where we fall back to the swtnl path.
