[PATCH 03/11] drm/radeon: UVD bringup v8
Christian König
deathsimple at vodafone.de
Mon Apr 8 03:41:29 PDT 2013
Just everything needed to decode videos using UVD.
v6: just all the bugfixes and support for R7xx-SI merged in one patch
v7: UVD_CGC_GATE is a write only register, lockup detection fix
v8: split out VRAM fallback changes, remove support for RV770,
add support for HEMLOCK, add buffer sizes checks
