my system configuration xen 3.4.2, oprofile 0.9.5( xenoprof patched ), dom0( jeremy''s pvops kernel 2.6.31.6 - patched dullor''s xenoprof patch ), domU( vanilla kernel 2.6.32 with paravirt enabled ), distribution( ubuntu 9.10 ) In passive mode, xenoprof seems to work well, opreport showed good information. but, in active mode, it seems not to be done correctly. my command is

Hi All. I''m trying to use xenoprof in my Xeon machine with PVOPS (3.1.0 kernel) & xen 4.1.1. In the past, I had failed to use the xenoprof in this environment. (1 year ago) While baremetal booting shows the counter object in /dev/oprofile/0 (or 1,2,3) , booting with xen fails to create those objects. Of course, opcontrol command doesn''t work. It only prints

Hi , I am getting following error when i try to run xenoprof /usr/local/bin/opcontrol: line 1082: echo: write error: Invalid argument Using 2.6+ OProfile kernel interface. Reading module info. Using log file /var/lib/oprofile/oprofiled.log Daemon started. what is this write error ? Any help is really appreciated. -John _______________________________________________ Xen-users mailing list

Hi, I want to use xenoprof to profile the overhead of the hypervisor. I patched the oprofile-0.9.5 using the patch from xenoprof.sourceforge.net Debian GNU/Linux 5.0 (lenny) Xen-4.0.1 + 2.6.32.27 (linux-2.6-pvops.git) Dom0 My platform is Intel(R) Core(TM) i7 CPU 960 @ 3.20GHz My problems are: In Dom0, But hardware performance counters don''t be mounted after initialization

Renato, When I tried running "opcontrol --start" (after previously running "opcontrol --start-daemon") in dom0, I get this error message: /usr/local/bin/opcontrol: line 1639: echo: write error: Operation not permitted and this message in the Xen console: (XEN) xenoprof: operation 9 failed for dom 0 (status : -1) It looks like opcontrol is trying to do this: echo 1 >

I am rebasing Fedora rawhide oprofile package to oprofile-0.9.7. The xenoprof patches on http://xenoprof.sourceforge.net/#download look a bit dated. The newest version is for oprofile-0.9.5. I massaged the patch oprofile-0.9.5-xen.patch to apply to oprofile-.0.9.7. Attached is that updated patch. Does this look reasonable? Is there a desire to get this into upstream oprofile? Or should the

The problem was because it is missing the "loop" module. the hotplug loads it automatically, while udev does not. The error xenoprof: Initialization failed. Intel processor model 15 for P6 class family is not supported" does not interference the winxp load.. so its ok. Does anyone know how to load osx86? It hangs at "booting from cd-rom". do I need kqemu/qemu xen? I

I''m looking into getting Xenoprof to tun in an HVM domain, since we will eventually need a profiler for HVM domains to track down areas of poor performance. (HVMs have poor performance? :) ) Being relatively new to OProfile, Xenoprof, and Xen internals, I would appreciate any pointers, tips, and comments on how to work the implementation. I see three basic areas of work. 1. Implement

Hi I am using oprofile 0.9.3 on xen cs 16540 on an Intel system. When I look at the top "hot" functions, I see p2m_change_type being one of the top function in xen-syms. This function is only in the svm (AMD) code and should not appear on an Intel system. I see that this function is not being clled at all when I am running my apps as I have put printk in the functions and they do

Renato, If one creates an HVM domain (say domain 1) and then does echo 1 > /dev/oprofile/passive_domains one then gets the following on the Xen serial console: (XEN) xenoprof.c:143:d0 xenoprof/x86 with autotranslated mode enabledisn''t supported yet (XEN) xenoprof.c:143:d0 xenoprof/x86 with autotranslated mode enabledisn''t supported yet (XEN) xenoprof.c:143:d0

Is it possible to monitor Core Events and Uncore Events simultaneously? Currently, it is not working now in my machine. When I type the command line like this, opcontrol --start-daemon --event=LLC_MISSES:6000::0:1 --event=LLC_REFS:6000::0:1 \ --event=MEM_UNCORE_RETIRED:6000:0x10:0:1 --event=MEM_UNCORE_RETIRED:6000:0x20:0:1 \ --xen=/boot/xen-syms-4.0.1-rc3 --no-vmlinux

Hello everyone, I''m trying to run Xenoprof (Oprofile 0.9.4) in Gentoo Linux 2.6.21-xen (64 bit) on an AMD 64 system and am facing the following two issues: 1. Xenoprof complains about a write error, but starts and runs anyway. dom0 # opcontrol --start-daemon --active-domains=0 --event=CPU_CLK_UNHALTED:75000::1:1 --vmlinux=/usr/src/linux-2.6.21-xen-dom0/vmlinux

Hi Renato, This patch is to add Xenoprof passive domain support in SMP environment. Basically: - It allocates per vcpu buffers for passive domain and maps them into primary domain''s space. - When primary domain gets sampled and triggers virq, its kernel module will handle passive domain'' samples besides its owns. There is potential buffer overflow if passive is very busy while

The original code only sets EN bit of IA32_PERFEVTSEL0 when profiling is started. Signed-off-by: Xiaowei Yang <xiaowei.yang@intel.com> Regards, Xiaowei _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

These patches address issues in the kernel part of xenoprof: * Ill-advised use of on_each_cpu() can lead to sleep with interrupts disabled. * Race conditions in active_domains code. * Cleanup of active_domains code.
