similar to: [PATCH][XENOPROFILE] add support for Intel CORE microarchitecture

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

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, 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

During my attempts to get the latest bridge networking model working on my system, I often invoked ''network-bridge stop'' with total failure. Attached is an updated version that works. -Andrew signed-off-by: Andrew Theurer <habanero@us.ibm.com> _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com

Dear, We released VMKNOPPIX(20070328) with Trusted Boot. http://unit.aist.go.jp/itri/knoppix/vmknoppix/index-en.html VMKnoppix is a collection of Virtual Machine Software, Xen, KVM, VirtualBox, QEMU, KQEMU(QEMU with Accelerator) and UserModeLinux. This version includes "Trusted Boot" (Trusted GRUB and IMA: Integrity Measured Architecture). === Features

Dear list, I am planning to buy a new server -because the new Core2 Duo based Xeons (5100 series) are considerably faster in some scenarios than Opteron machines while not beeing more expensive, I would like to hear some real-world experiences from people who have installed CentOS 4.3 or 4.4 on such a setup. Specifically: CPU: 2x Intel Xeon 5100 2GHz Board: Intel S5000 chipset RAID5:

I've been trying to get oprofile results for jitted code without success. I built an 3.5.0 llvm with oprofile enabled, and tested it with lli on a small test case. I built the latest oprofile from the git repository. Debugging I can see that lli is registering the listener and making the oprofile calls to the libopagent api to specify the names and address ranges of jit'd routines, and

Mi Maurice, A follow up to Andy's comments: MCJIT can find line numbers for ELF files, at least in limited circumstances. I know because I broke the regression test for it while doing some cleanup recently. ;) Looking at lib/ExecutionEngine/OProfileJIT/OProfileJITEventListener.cpp, I see the line: // TODO: support line number info (similar to IntelJITEventListener.cpp) >From a glance at

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

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.

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

( I don't know if it's allowed to ask such question, if not, please remind me. ) I know Intel implemented several static branch prediction mechanisms these years: * 80486 age: Always-not-take * Pentium4 age: Backwards Taken/Forwards Not-Taken * PM, Core2: Didn't use static prediction, randomly depending on what happens to be in corresponding BTB entry , according to agner's

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

Hi, I ran xenoprof with the event mask LLC_MISSES:10000. This should be L2 cache misses on Core2 arch. After the run when I run opreport it displays : Counted *L2_RQSTS* events (number of L2 cache requests) with a unit mask of 0x41 (multiple flags) count 10000 LLC_MISSES:10000 | ..... My questions was whether the message is incorrect or the event mask is not being set correctly by oprofile. My

At OLS I gave a talk on some of the Xen scalability inhibitors, and one of these was writable page tables. We went over why the feature does not scale, but just as important, we found that the uniprocessor case does not provide any advantage either. These tests were done on x86_64, so I wanted to run the 1-way test on 32 bit to show the same problem. So, I have run with writable PTs and
