From a6fbefa67b5b0ed1ee42a9034ee74dfaed1c389a Mon Sep 17 00:00:00 2001 From: Samuel Pitoiset Date: Wed, 25 Apr 2018 10:56:15 +0200 Subject: [PATCH] radv: fix DCC enablement since partial MSAA implementation dcc_msaa_allowed is always false on GFX9+ and only true on VI if RADV_PERFTEST=dccmsaa is set. This means DCC was disabled in some situations where it should not. This is likely going to fix a performance regression.
