[Mesa-dev] [PATCH 18/20] radeonsi: port texture improvements from r600g
Marek Olšák
maraeo at gmail.com
Wed Aug 7 17:20:58 PDT 2013
This started as an attempt to add support for MSAA texture transfers and
MSAA depth-stencil decompression for the DB->CB copy path.
It has gotten a bit out of control, but it's for the greater good.
Some changes do not make much sense, they are there just to make it look
like the other driver.
With a few cosmetic modifications, r600_texture.c can be shared with
a symlink.
