Piglit test: spec/!OpenGL 1.2/texture-packed-formats We are seeing this Piglit regression on pineview (chromebook, the only chrome platform in our stable still using X and tested with Piglit) The version of Mesa that ChromeOS is currently using passes this test in piglit. It is based on the following commit plus an additional 34 patches: 1291788 glsl: Generate unique names for each const array lowered to uniforms [Nov 2014-ish] It fails in the following Mesa commit: c2a0600 i965: Don't set NirOptions for stages that will use the vec4 backend [May 2015-ish] It also fails in this recent Mesa commit: 1a6e4f46ed117b393e26aff326e5b05d4aea7fb0 (gallium: remove explicit values from PIPE_CAP_ enums) [~June 10, 2015]
I built and tested mesa=c2a0600 on g33. The test provided the following output, running against the latest drm with gbm back end: ---------------------------------------------------- </testcase> <testcase classname="piglit.spec.!opengl 1_2" name="texture-packed-formats.g33m64" status="pass" time="0.146700143814"> <system-out>/tmp/build_root/m64/lib/piglit/bin/texture-packed-formats -auto </system-out> <system-err>i915: unsupported texture swizzle for format 6 i915: unsupported texture swizzle for format 6 i915: unsupported texture swizzle for format 5 i915: unsupported texture swizzle for format 5 i915: unsupported texture swizzle for format 131 i915: unsupported texture swizzle for format 131 i915: unsupported texture swizzle for format 6 i915: unsupported texture swizzle for format 6 i915: unsupported texture swizzle for format 5 i915: unsupported texture swizzle for format 5 i915: unsupported texture swizzle for format 131 i915: unsupported texture swizzle for format 131 </system-err> </testcase> ---------------------------------------------------- status="pass" differs from what was reported in the bug. I can't bisect further if I can't repro.

Brian Wilson said: > It fails in the following Mesa commit: > c2a0600 i965: Don't set NirOptions for stages that will use the vec4 backend [May 2015-ish] Incorrect. The actual Mesa tree that Brian's team is validating is commit c1a0600 plus many patches. I've the pushed the full tree, patches included, to git://github.com/chadversary/mesa refs/tags/chadv/cros-gerrit-262788-patched Also, the Piglit being tested is the following commit plus a few incosequential patches. commit 4069bec62a8a99c44573395ea1597694eeee760f Author: Marek Olšák <marek.olsak@amd.com> AuthorDate: Thu Apr 30 14:11:26 2015 +0200 Commit: Marek Olšák <marek.olsak@amd.com> CommitDate: Thu Apr 30 22:41:02 2015 +0200 Subject: framework: use the correct executable for GLES parser tests Building that Piglit against recent Mesa, however, produces an error at linktime. The fix requires backporting Piglit commit 845ba0e4dfb9372307f5d3032abdd0860e76731b.
I was able to reproduce this bug using the old versions of piglit and mesa piglit: 1f39e07d44f7d78557d69c505168afb8eab913c6 mesa: c2a0600 After updating piglit to the latest revision, the test passes. Based on this information, I think it is safe to conclude that this bug does not indicate a regression in mesa. Instead, it is caused by using an obsolete version of piglit.
