Applied. Given how many bugs we've had with these perf_boxes settings, we may want to just nuke them at some point. It looks like the userland debug code that used the flags went away in 2007. Does anyone care for them continuing to exist? Do we have any obligation to keep them? I think for any future performance debug like these did, we'd just expose values in debugfs (it keeps the debug code from interfering with app behavior, anyway). -- Eric Anholt e...@anholt.net eric.anh...@intel.com
