second patch (SVM) for hvm xenoprofile support. Applies cleanly to 11470. Signed-off-by: Tom Woller <thomas.woller@amd.com> Please apply to xen-unstable.hg. hvm_xenoprofile_2.patch - The second patch adds the actual xenoprofile fixes for SVM: 1) hvm function (svm_oprofile_get_eip()) This new hvm table function is called from the op_module_athlon.c code, and returns the proper eip and

Third patch (VT) for hvm xenoprofile support. Applies cleanly to 11470. Signed-off-by: Tom Woller <thomas.woller@amd.com> Please apply to xen-unstable.hg. hvm_xenoprofile_3.patch - The third patch adds the actual xenoprofile fixes for VT: I checked (verified by Renato), that the VT traces look ok also. There is some code that I am unsure about in the vmx_oprofile_get_eip(): i.e using the

Keir, The following 3 patches allow HVM (SVM and VT) guests to be passively 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

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

Add xenoprofile function to oprofile to obtain the mode, adding check for hvm guest. Applies cleanly to xen-unstable c/s 11831. Please apply to xen-unstable.hg. We also want these patches to be in a 3.0.3-1 base whenever that is branched.

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:

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

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 just added 32GB memory in my system and wanted Xen to see that memory, so enabled PAE in xen0 and XenU. I did a make menuconfig in xen0 and xenU, then did a make in xen-unstable and a make install. Whilebooting this kernel, I get the above error PAE 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.

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

Hi. I got a asus SABERTOOTH 990FX, reading about vt-d, I read the MoBo that support IOMMU and there was chip 990FX, them I pick this MoBo, the BIOS that came with the board was 0402 05/11. I follow the xen wiki, I''m running Xen 4.1.1 from Gitco on Centos 5.7 x64, by default the MoBo have the IOMMU disable, I enable the feature IOMMU = 64MB, save the bios settings, restart, turn off
