From 3eb8289aa4cb599e9297ee1a1b5cfbae35ee562a Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Tue, 21 Oct 2014 11:28:53 -0400 Subject: [PATCH] freedreno: mark scissor state dirty when enable bit changes We don't have a scissor enable bit in hw, so when a raster state change results in scissor enable bit changing, we need to also mark scissor state as dirty.
