What we learned: - The reason vector_justify = TRUE fixed one of the tests, but kept some failing is because it was reversing X and Y coordinates, so only the first 3 component sshort test run was getting placed properly (because the test case has x and y start with the same value). The subsequent ones were growing down instead of right. - of course we can then get it working by changing the swizzle order in u_format.csv to yxz1 for the 3 component short and 3 component half float tests. clearly not the "right" fix, but was interesting to see all the tests working. - if i leave vector_justify to FALSE, but change <a href="attachment.cgi?id=130980" name="attach_130980" title="the patch i'm running through piglit now">attachment 130980</a> <a href="attachment.cgi?id=130980&action=edit" title="the patch i'm running through piglit now">[details]</a> <a href='page.cgi?id=splinter.html&bug=100613&attachment=130980'>[review]</a> to use fetch_width instead of format_desc->block.bits then all the 3 component sshort tests and half float tests start working, but then r32g32b32_sscaled start failing. So, the above patch fudges it to make everything in draw-vertices and draw-vertices-half-float work. Obviously not shippable, but might aid in figuring out what's going on?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
