From: Nicolai Hähnle Date: Mon, 23 Jul 2018 07:47:19 +0000 (+0200) Subject: radeonsi/gfx10: mask DCC tile swizzle by alignment X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d028440f578fb2ab96e64846c8f378bd6b247886;p=mesa.git radeonsi/gfx10: mask DCC tile swizzle by alignment DCC alignment can be less than the alignment of the main surface. In that case, the DCC tile swizzle needs to be masked accordingly. Should have no impact on pre-gfx10.
