...ssively profiled using the very latest patches from Renato. These patches apply to 11470. Renato''s patches: http://xenoprof/sourceforge.net oprofile-0.9.1-xen-r2.patch And also a patch not posted FAIK (oprofile-0.9.1-fix-hvm-addr-overlap.patch) which is in the attached tar.bz2 file. hvm_xenoprofile_1.patch - The first patch is merely the same patch that I posted a few weeks ago. The STGI code is moved from the exits.S files, and into the vmexit handler. The extra do_nmi() is removed allowing the host to handle the NMI when the stgi instruction is executed. This patch allows the second patc...

Remove the do_nmi() call from the vmexit logic, as the NMI is held pending and will be handled in the context of the host when the STGI instruction is executed. This patch only modifies AMD-V code. This patch is required even without the other Xenoprofile patches applied. Applies cleanly to c/s 11831. Please apply to xen-unstable.hg regardless of the other patches. We also want these patches to be in a 3.0.3-1 base whenever that is branched. Signed-off-by: Tom Woller <thomas.woller@amd.com> Thanks --Tom __________________________...

Hi Folks, I want to profile the vista hvm domain using Xenoprof and I don''t know what to specify for its kernel image file required by --passive-images option of opcontrol utility. Could someone please tell me if Xenoprof supports Vista kernel image and if yes, which file should I specify as its kernel image. I am using Xen-3.2.1 Thanks, Sanjay -- ---------------------- Dr. Sanjay

Hi, I want to get the performance data like documents <<Xenoprofoverview&Networking Performance Analysis>> (http://www.xensource.com/files/xs0106_xenoprof.pdf ). But how can I get the modules'' profile in kernel? Now I use command: Opcontrol --no-vmlinux --separate=kernel,cpu --start-daemon ...run benchmark Opcontrol --sutdown Opreport >list The report shows: CPU:

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

...mode mismatch. I looked under xen/include/asm-x86/processor.h has #define X86_CR4_PAE defined and so does cpufeature.h have this defined. #define X86_FEATURE_PAE What else should I have done to enable a PAE enabled Xen kernel. I am using xen 3.0.0 (xen-unstable) and cannot move to 3.02 due to xenoprofile not ready there Thanks - Padma _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hello everyone, I''m wondering what the current status of hardware performance counter usability in Xen is. I see some old posts describing the diffculties of virtualizing hardware counters within dom0 and the domUs, but not much else. Have they been implemented or are they in the process of being implemented? Or are there no future plans for implementation? Any help would be

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 >

Hmm.. good question. I don''t know, it''s always done for me here. One option would be to just download OVM from edelivery.oracle.com,

My recent interest in the TPR-write problem has got me thinking about if there is any other optimisation that could be done for windows, especially as a few people have reported issues with more than a few processors, and they say they are already running 2K3sp2 which should have TPR optimisation in it already. Is there any facility currently for profiling the frequency of vmexit''s to
