It will hang very quickly after 0.5 secs and produce the following output on xm dmesg: (XEN) traps.c:2230:d25 Domain attempted WRMSR 00000000c0010004 from 00009310:79804ace to 00000000:00000000 (XEN) traps.c:2230:d25 Domain attempted WRMSR 00000000c0010000 from 00000009:0487e489 to 00000000:00430076 BR, Carsten. ----- Originalnachricht ----- Von: Carsten Schiers Gesendet: Mon, 5.7.2010 11:09 An: xen-devel@lists.xensource.com Betreff: [Xen-devel] Question on xenpm Dear all, after having upgraded my server from AMD 4050e to X4 640, I now use cpufreq=xen and had to adapt a munin script (monitoring tool) to display the residency in the different P-states. This script uses /sys/device/system/cpu/cpu0/cpufreq to read out the information, whereas I now use xenpm get-cpufreq-state. Before I noticed that the CPU is in highest possible P-state (lowest frequences) nearly all of the time, and a minimal percentage in the lowest. Now I can see a 50/50 distribution. Interesting enough, the xenpm get-cpuidle-state will show that the CPUs are at aprox. 90% in C1 idle state. Can there be a difference in how the two methods to collect the info are working? I mean something like xenpm will not count residency when in C1, but cpufreq driver will normaly do? BR, Carsten. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
