big.LITTLE Weekly Test Results Report

Progress

  • RC1 Testing Complete, weekly snapshot testing resumed
  • NB: Images using the integrated switcher still had the same latest changeset id when they were built, so integrated switcher tests for this week should be identical to RC1 - a whole lot of new changes just showed up in the last 24 hours though by looking at the branch - so next set of tests should be much more interesting to see.
  • A few new bugs uncovered by way of experiment/setting up for demo! Demos are great for shaking out problems :)

  • several of the bugs we have right now that manifest during switching seem to be difficult to reproduce reliably
  • Good progress on the ubuntu rootfs image
