And that won't really speed up much since we're adding piles more testcases at a pretty quick rate. And many of these new testcases are CRC based, so inheritely take some time to run. So I think longer-term we simply need to throw more machines at the problem and run testcases in parallel on identical machines. Wrt analyzing issues I think the right approach for moving forward is: a) switch to piglit to run tests, not just enumerate them. This will allow QA and developers to share testcase analysis. b) add automated analysis for time-consuming and error prone cases like dmesg warnings and backtraces. Thomas&I have just discussed a few ideas in this are in our 1:1 today. Reducing the set of igt tests we run is imo pointless: The goal of igt is to hit corner-cases, arbitrarily selecting which kinds of corner-cases we test just means that we have a nice illusion about our test coverage. Adding more people to the discussion. Cheers, Daniel Intel Semiconductor AG Registered No. 020.30.913.786-7 Registered Office: Badenerstrasse 549, 8048 Zurich, Switzerland. </body> </html>
