From: Ilia Mirkin Date: Fri, 19 Aug 2016 00:12:29 +0000 (-0400) Subject: a4xx: only disable depth clipping, not all clipping, when requested X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=cd8e30452f6d308a0c5e5668d6bba63f01895f1f;p=mesa.git a4xx: only disable depth clipping, not all clipping, when requested The previous bit disables the whole clipper, including the regular viewport-related clipping that would go on. The two new bits disable near and far clipping (separately, as verified with the depth-clamp-range piglit).
