Subject: vc4: Declare what vertex formats we actually support.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e1ce61089999905b35e15b2720311d54b80eeccc;p=mesa.git

vc4: Declare what vertex formats we actually support.

We will support more than this eventually, but for now this makes u_vbuf
format-convert a few things (32-bit snorm and scaled, doubles) for us.
