From 2bbf964af84c3220245c1534951341fff4b4ee44 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Wed, 2 Nov 2016 01:23:11 +0000 Subject: radv: enable conditional discard optimisation on radv. This fixes a bunch of GPU hangs introduced in some CTS tests like dEQP-VK.memory.pipeline_barrier.host_write_uniform_buffer.65536 It works around an issue seen in the LLVM backend, but also makes the radv code work more like the radeonsi stack.
