From d4e6de9e385579d49cd5f51e643d0141c81b5604 Mon Sep 17 00:00:00 2001 From: Lucas Stach Date: Thu, 18 May 2017 16:44:18 +0200 Subject: etnaviv: simplify transfer tiling handling There is no need to special case compressed resources, as they are already marked as linear on allocation. With that out of the way, there is room to cut down on the number of if clauses used.
