[Mesa-dev] [PATCH v2 0/7] Fix handling of 8-bits-per-channel SRGB and SNORM formats

[Richard Sandiford]

> Similar to the L/A and R/G series I just posted, this one fixes the SNORM
> and SRGB 8888 formats.  The UNORM ones were done last year as part of the
> original big-endian work.

v2, with subject lines fixed to include the "component:" bit.  No code changes
from v1.

Richard Sandiford (7):
  util: Add PIPE_FORMAT_x8B8G8R8_SNORM formats
  util: Define PIPE_FORMAT_xyzw8888_{SNORM,SRGB} aliases
  mesa: Tweak unpack name for MESA_FORMAT_R8G8B8X8_SNORM
  mesa: Fix alpha component in unpack_R8G8B8X8_SRGB.
  mesa: Fix _mesa_texstore_signed_rgb?8888 for big-endian.
  mesa: Add MESA_FORMAT_{A8R8G8B8,X8R8G8B8,X8B8G8R8}_SRGB
  st/mesa: Fix handling of 8888 SNORM and SRGB formats for big-endian
