Subject: nv50,nvc0: advertise GL_FIXED vertex buffers as supported
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=220abb7adf61872ddfb5b250be8085ee0fc2416d;p=mesa.git

nv50,nvc0: advertise GL_FIXED vertex buffers as supported

We'll handle them like f64 vertex buffers, by falling back to
copying vertex data to the command buffer through translate.
