[Mesa-dev] [PATCH 02/11] util: Add PIPE_FORMAT_AnLn and PIPE_FORMAT_GnRn formats

[Dave Airlie]

From: Richard Sandiford <rsandifo at linux.vnet.ibm.com>

...i.e. formats in which the alpha or green channel is first in memory.

This means that each LnAn and RnGn format has a reversed counterpart,
which is necessary for handling big-endian mesa<->gallium mappings.
