Jake Burkholder offered to port the mutex code, and I discussed this with Matt last week, who had no problems with Jake doing it. As of last night, it sounds like Jake essentially has this done for i386, and Doug Rabson will be following soon with the alpha bits. Jake's patch set also includes the pertinent parts of Matt's work (per-CPU idle processes, some of the schedlock changes, etc.). I'll be adding a link to Jake's most recent patch set on the web page (http://people.freebsd.org/~jasone/smp/) shortly. Meanwhile, you can get Jake's patch set at: http://people.freebsd.org/~jake/smpng2.tar > 2.

A successful buildworld would be a satisfactory test of stability in my eyes. Hopefully we can do that well. =) Jason To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-smp" in the body of the messagehelp
