From: Samuel Pitoiset Date: Sat, 13 Feb 2016 23:14:34 +0000 (+0100) Subject: nvc0: fix compute state initialization on GK110+ X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=bc331dd8389312cbb2f1bac323e7cd79b155cfa0;p=mesa.git nvc0: fix compute state initialization on GK110+ Because our firmware doesn't support the GK110_COMPUTE.FIRMWARE[0x6] method the GPU hangs when it is used. Removing it fix the issue and allow to launch compute shaders on GK110+. Tested on GK208 and GM107.
