[PATCH] drm/radeon/kms: add htile support to the cs checker
j.glisse at gmail.com
j.glisse at gmail.com
Fri Feb 10 10:35:21 PST 2012
From: Jerome Glisse <jglisse at redhat.com>
For 6xx+. Required for mesa to use htile support for HiZ/HiS.
Userspace will check radeon version 2.14 with is bumped either
by tiling patch or stream out patch.
