Subject: radeonsi: allow fast color clear and Hyper-Z with 1D-tiled surfaces on CIK
X-Git-Tag: upstream/10.3~2685
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4d641803e8f8763dcf4a262c6bcf2d1ba0431ca2;p=platform%2Fupstream%2Fmesa.git

radeonsi: allow fast color clear and Hyper-Z with 1D-tiled surfaces on CIK

This depends on my kernel fix. Hyper-Z is still disabled by default.
