[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.
