From: Ilia Mirkin Date: Tue, 17 Mar 2015 05:00:38 +0000 (-0400) Subject: freedreno/a3xx: point size should not be divided by 2 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7fc5da8b9392042b5f8a989d2afa49ea1944f9a9;p=mesa.git freedreno/a3xx: point size should not be divided by 2 The division is probably a holdover from the days when the fixed point inline functions generated by headergen were broken. Also reduce the maximum point size to 4092 (vs 4096), which is what the blob does.
