Subject: drm/radeon/kms/evergreen: implement gfx init
X-Git-Tag: v2.6.35-rc1~451^2~86^2~4
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=32fcdbf4084544c3d8fa413004d57e5dc6f2eefe;p=karo-tx-linux.git

drm/radeon/kms/evergreen: implement gfx init

This initializes the gfx engine so accel can
eventually be used.
