Subject: r600: handle SIMD allocation issue with HS/LS
X-Git-Tag: upstream/17.1.0~13935
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b8df7d03c8ff045233dff4c98016329577204ae6;p=platform%2Fupstream%2Fmesa.git

r600: handle SIMD allocation issue with HS/LS

At least one SIMD must be kept away from the HS/LS
stages in order to avoid a hw issue on evergreen/cayman.

This patch implements this workaround.
