piglit comparison summary
Hello,
I'm seeing quite a few new piglit failures on my CYPRESS card. Git bisect
points to the following commit:
54c4d525da7c7fc1e103d7a3e6db015abb132d5d is the first bad commit
commit 54c4d525da7c7fc1e103d7a3e6db015abb132d5d
Author: Jan Vesely <<a href="mailto:jan.vesely@rutgers.edu">jan.vesely@rutgers.edu</a>>
Date: Wed Jun 15 19:41:22 2016 -0400
r600g: Enable FMA on chips that support it
v2: Merge with PIPE_SHADER_CAP_DOUBLES
Add CHIP_HEMLOCK
v3: only set the instruction on EG and CM

Here's a "./piglit run quick" showing last good and first bad commits:
summary:
name: mesa-cbb5adb mesa-54c4d52
---- ------------ ------------
pass: 44981 44015
fail: 963 1930
crash: 5 5

Roughly half of the new failures are in arb_gpu_shader_fp64 (including all 37
tests in the uniform_buffers subcategory), while the other half are in
glsl-4.00/execution/built-in-functions. Output from "./piglit summary console"
included in the compressed attachment.
I'm glad to see these older cards are still getting attention. I'd be happy to
test any patches. Thanks,
James Harvey
