From a563045009fe01689553c6e3db2b030cd074ce8a Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Fri, 13 Mar 2015 01:36:57 -0400 Subject: [PATCH] freedreno: fix slice pitch calculations For example if width were 65, the first slice would get 96 while the second would get 32. However the hardware appears to expect the second pitch to be 64, based on halving the 96 (and aligning up to 32). This fixes texelFetch piglit tests on a3xx below a certain size. Going higher they break again, but most likely due to unrelated reasons.
