From 3d5f61a262b78de9a800872553955314995e42fd Mon Sep 17 00:00:00 2001 From: Samuel Pitoiset Date: Sun, 14 Feb 2016 00:32:34 +0100 Subject: [PATCH] nvc0: enable compute support on GK110:GM200 with an envvar Without this NVF0_COMPUTE environment variable, compute support is initialized by default and this is not what we want for now because it might break 3D. It will be enabled by default once we are sure it won't break anything. Please note that compute support on GM200+ is not enabled yet because it needs to be double-checked.
