Dear all, I have enable xen-3.4.2 oprofile configuration and compiled the oprofile-0.9.5.tar.gz with patch oprofile-0.9.5-xen.patch. I ''scp'' the xen-syms kernel and the vmlinux kernel to domU. I want to start the mode with: opcontrol --start --event=CPU_CLK_UNHALTED:1000000:1:1:1 --xen xen-syms-3.4.2 --vmlinux=vmlinux But it shows the result like: testvm02:~# opcontrol --start --event=CPU_CLK_UNHALTED:1000000:1:1:1 --xen xen-syms-3.4.2 --vmlinux=vmlinux You cannot specify any performance counter events because OProfile is in timer mode. I have read previous thread ''Xenoprof: getting Oprofile out of timer mode?''(http://copilotco.com/mail-archives/xen.2006/msg12482.html). It seems the problem has been fixed. But why I cannot run xenoprofile in active mode in domU. Does it have something to do with apic?(I have configured in /etc/xen/testvm02.cfg with lapic) My machine is HP proliant. I can provide further information if needed. Thanks, Jeff _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

No. It returns timer mode. trillian14:~# opcontrol -l Using timer interrupt. Is it possible that power regulator has something to do with the error because I see some APIC entries(dmesg) are always disabled even if I enable all APIC in BIOS. Have you had experience on HP proliant machine?

Have you had experience on HP proliantI doubt it.> machine?No. I think this requires a bit more of digging in how this (oprofile) used to work in older version of Xen and Linux and see what needs to be fixed to get this working again. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
