Subject: gallium: Introduce a new format to disambiguate PIPE_FORMAT_R8G8B8A8_UNORM.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=cd8b6523039d68459756db487566a97fac1d4d75;hp=d170d73b16aef3e61a7b50038e7208e46d7d1223;p=mesa.git

gallium: Introduce a new format to disambiguate PIPE_FORMAT_R8G8B8A8_UNORM.

PIPE_FORMAT_R8G8B8A8_UNORM now means just

  R8 G8 B8 A8

PIPE_FORMAT_R8G8B8A8_UNORM_REV means

  A8 B8 G8 R8

And the thumb rule is vertex buffers refer to PIPE_FORMAT_R8G8B8A8_UNORM,
while textures refer to PIPE_FORMAT_R8G8B8A8_UNORM_REV.

PIPE_FORMAT_R8G8B8A8_UNORM_REV is just a temporary name.
