First of all I would like to say a big thanks to Emanuel and Nicolas for testing yesterdays tests on Nvidia hardware it helped me spot and fix up a number of issues that the AMD drivers weren't as strict about.   I've submitted this first batch of tests to the piglit mailing list and now waiting for feedback. The latests version of the tests can be found here:   As for working on the extension itself I didn't get as much done today as I had hoped due to a seemingly simple bug taking longer to track down than it should have 🙁 but its fixed now.   Plans for tomorrow:   I know yesterday I talked about trying to get a simple execution test fully running, but I now think it is better to get the compile tests passing first so this is what I will be working on tomorrow.
