From 9039cf70fa0b785f390c649486e12d6c10e9142b Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Wed, 25 Jul 2018 13:14:58 +1000 Subject: [PATCH] r600: reduce num compute threads to 1024. I copied this value from radeonsi, but it was wrong, 1024 seems to be correct answer from looking at gpuinfo. This should fix a few compute shader related hangs.
