Tested Mesa commit: c2a0600d5b0645533ba442b5ab879b23c2564a4d: "i965: Don't set NirOptions for stages that will use the vec4 backend." Plus patches: - 10.6-i965-do-not-round-line-width-when-multisampling-or-a.patch - 10.6-mesa-add-GL_RED-GL_RG-support-for-floating-point-tex.patch - 10.6-i965-Momentarily-pretend-to-support-ARB_texture_sten.patch - 10.6-Revert-i965-Advertise-a-line-width-of-40.0-on-Cherry.patch Testing a Mesa update on ChromeOS, the following dEQP tests fail on BYT: - dEQP-GLES3.functional.shaders.texture_functions.texturelod.usamplercube_vertex - dEQP-GLES3.functional.shaders.texture_functions.texturelod.usamplercube_fragment Sample failure: "Image comparison failed: difference = 450.979, threshold = 0.05" These tests pass on HSW, BDW and BSW, and passed on BYT with an older Mesa commit (November 18, 2014: 129178893b2260df22db96327c5ca9c2ce7db046 "glsl: Generate unique names for each const array lowered to uniforms" + ~10 patches)
Please assign i965 bugs to Component: Drivers/DRI/i965.
maybe related to bug #91114, at least lod calculation there seems broken
I believe this was fixed by commit commit d4a5a61d445e683c20de00c1febe847b4c2db910 Author: Kenneth Graunke <kenneth@whitecape.org> Date: Mon Mar 28 20:07:13 2016 -0700 i965: Don't use CUBE wrap modes for integer formats on IVB/BYT. Please reopen if it is not.
