Sounds great. I disabled anonymous access of that gate. You can have a try to make sure it's not open to everyone: hg clone ssh://a...@hg.opensolaris.org//hg/intel-platform/intel-numatop If it's expected, you can contribute your work to it. Thanks for the sharing! Thanks, -Aubrey _______________________________________________ perf-discuss mailing list perf-discuss@opensolaris.org
