[Mesa-dev] [PATCH v2] radeonsi: Add CIK SDMA support
Michel Dänzer
michel at daenzer.net
Wed Oct 1 01:42:40 PDT 2014
From: Michel Dänzer <michel.daenzer at amd.com>
Based on the corresponding SI support.
Signed-off-by: Michel Dänzer <michel.daenzer at amd.com>
---
v2: Remove fallback for liner->tiled copies which was accidentally left
over from debugging.
