For future reference, sysprof and perf can be used to perform system wide profiling - that is you can launch them after starting the task you need to profile. For sysprof this is its default mode, and for perf you need 'perf record -a' A quick 'sudo perf top' is always a useful first step. For best results, make sure you have debugging symbols and frame pointers. -Chris -- Chris Wilson, Intel Open Source Technology Centre --===============1688810574== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/dri-devel --===============1688810574==--
