Fix matrix vertex attributes in NIR |
||
I think these are a NIR related regression. They work on master with INTEL_DEBUG=vec4vs and they work on 10.6 with INTEL_USE_NIR=0. (Well, at least the one test I tried...) I think I probably broke matrix vertex attributes that aren't mat4s. Created attachment 116863 [details] [review] Fix matrix vertex attributes in NIR I think this patch should fix most of them. FWIW, the patch is on the mailing list: http://lists.freedesktop.org/archives/mesa-dev/2015-July/088026.html I've also posted a backport to 10.6 here: http://lists.freedesktop.org/archives/mesa-stable/2015-July/002746.html I tested Ken's patch, it fixes 1256 dEQP failures and puts BDW at parity with HSW. Fixed on master with: commit 73d0e7f3451eaeb62ac039d2dcee1e1c6787e3db Author: Kenneth Graunke <kenneth@whitecape.org> Date: Wed Jul 1 20:13:00 2015 -0700 i965/vs: Fix matNxM vertex attributes where M != 4. Matrix vertex attributes have their columns padded out to vec4s, which I was failing to account for. Scalar NIR expects them to be packed, however. Fixes 1256 dEQP tests on Broadwell.
