All I find in Dejanews is: The MTRR interface in FreeBSD was developed under consultation with the XFree86 and Xi Graphics folks. I haven't heard any complaints from them lately. > Also, I wonder if you've seen/heard of an MTRR patch for 3.2-RELEASE :-) You could try to backport the two sets of commits I just made to the -stable branch, but you might be better off moving to -stable or to 3.3-RELEASE. -- \\ The mind's the standard \\ Mike Smith \\ of the man. \\ msmith@freebsd.org \\ -- Joseph Merrick \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
