From 28c2573b4f1b311145b3f21a1794adb3dcd5f61a Mon Sep 17 00:00:00 2001 From: Marek Olšák Date: Sun, 17 Apr 2016 15:18:31 +0200 Subject: radeonsi: don't flush CB/DB caches for performance counters MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit I'm not sure about this. This will make the engines go idle, but the caches will be unflushed. This should match app behavior without performance counters, which can be a good thing.
