I had a lot of GPU lockups and CS errors. I reduced piglit tests to the shaders set. Most of them passes correctly, 3 are marked as fixed, 9 of them regressions, no chrases. Trying to dig more and found out which shader is causing trouble but I haven't found out how to run a specific test with piglit. Documentation isn't to friendly...Id appreciate some help with this. Test that failed : glx-visuals-stencil-pixmap glsl-const-builtin-notEqual-06 glsl-fs-discard-02 glsl-fs-fogcolor-statechange glsl-fs-loop-two-counter-02 glsl-fs-loop-two-counter-04 glsl-fs-vec4-indexing-5 glsl-fs-vec4-indexing-6 glsl-uniform-non-uniform-array-compare > > [1]: see section "Regression debugging" at > http://people.freedesktop.org/~vadimg/r600-sb.html > > >> Vadim > > > > _______________________________________________ > > mesa-dev mailing list > > mesa-dev@lists.freedesktop.org > > http://lists.freedesktop.org/mailman/listinfo/mesa-dev</body></html>
