Subject: r600g: add texture tiling enable under a debug option.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=089aa0ba247cee908ae689f8e4f3ffc457ce7627;p=mesa.git

r600g: add texture tiling enable under a debug option.

At the moment you need kernel patches to have texture tiling work
with the kernel CS checker, so once they are upstream and the drm version
is bumped we can make this enable flip the other way most likely.
