From 6206da736c84c4f7316ab586c886b4865fda8805 Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Thu, 15 Oct 2015 16:22:23 -0400 Subject: [PATCH] freedreno/a3xx: cache-flush is needed after MEM_WRITE Otherwise the mem2gmem blit would see potentially bogus texture coordinates. Fixes an issue that shows up with glamor.
