From 94bb33617d1e8978dc52b8aaa4eb41bfb6703f79 Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Fri, 17 Oct 2014 08:57:16 -0400 Subject: [PATCH] freedreno/a3xx: only emit dirty consts If app only updates (for example) vertex uniforms, it would be nice to only re-emit those and not also frag uniforms. Means we need to mark the first frag shader const buffer dirty after a clear.
