| I'm quite surprised at your observations. | (The other thing I noticed is that your glxgears performance is very | very good. This may indicate that something else is going on. | Perhaps the intel driver now uses PAT. I'm going to ignore this | possibility for now.) I now think that recent open-source intel drivers use PAT. I don't have a suitable test box with Fedora but I've got one running Ununtu 8.10 and Ubuntu 9.04 beta. This is my ThinkPad x61t with 4GiB of RAM. - the video buffer's address range has an MTRR that is covered by another - under 8.10, performance is increased if the MTRRs are rearranged - under 9.04 beta performance is good even with the default MTRR setup. This matches Bob Marcan's observation with Fedora 10 on his box. Thanks, Bob, for your help. -- fedora-list mailing list [email protected] To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
