So, I continued my deep-dive into cpufreq handling for the above mentioned CPU. Compiled and installed xen-unstable.hg and linux-2.6.18-xen.hg as of 16.01.09 with the config from the original Bastian Blank (waldi) kernel I use. I left out dist/install/etc/xen because it killed my network config. Hope this doesn't introduced finding 3. Finding 1 (good!): no powernow-k8 out of synchs anymore! Finding 2 (good!): no TSC drifts anymore! Finding 3 (bad): DomUs with PCI devices handed over complain that they need also the PCI device of the VGA card (although it doesn't share an IRQ with the card in question. Although I still have trouble to treat the CPU so bad that the ondemand governor accelerates a bit, I am thinking I'm on the right way. This a bit of reporting just in case others check out the same configuration. BR, Carsten. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
