Subject: r600/sfn: Disable FP64 for pre-CEDAR
X-Git-Tag: upstream/22.3.5~5386
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=14ab267c76fddf86c5c5bb6bad02648071ceb1b0;p=platform%2Fupstream%2Fmesa.git

r600/sfn: Disable FP64 for pre-CEDAR

There is no point in trying to get the softfp to work here,
since these cards don't support tesselation shaders, they will
never get OpenGL 4.0.

v2: Fix formatting (Filip)
