Good afternoon, We are running callgrind and cg_annotate version 3.6.1 on Centos Linux Version 5.5 x86_32. One month ago Mr. Josef Weidenorfer issued a special patch that fixed callgrind on Centos Linux Version 5.5 x86_32. We can now profile complex C++ programs which use our own shared library libmdMatchup.so. However, when we use version 3.6.1 cg_annotate callgrind.out.22533 --auto = yes

Keith Roberts, Thank you for your suggestion about doing a grep of the source code. We found mmap.S in ../sysdeps/unix/sysv/linux/i386. We looked in mmap.S and found a lot of assembly code. Could you please tell us if any of the assembly code call the kernel syscall handler for mmap.s? Also, we ran make for the kernel Makefile and we obtained the following result shown below. Could you please

Hi, For the last day or two I having been trying to get Valgrind/Callgrind 3.6.1 to work on Centos Linux 5.5 using a simple Fibonacci C++ program(shown below). After compiling the program using g++ -g -o MatchUpAccurate MatchUpAccurate.cpp, we run: /home/frankc/DQTTest/valgrind-3.6.1/coregrind/valgrind --tool=callgrind --dump-instr=yes --simulate-cache=yes --collect-jumps=yes

Hi there, I''ve been trying incorporate the in_place_editor, but have had no luck so far. I read the Ajax.In Place editor wiki on script.aculos.us which was informing, but still left me wondering about a few things. Here''s what I''m trying to do. A user has a profile page which lists their name, age, homepage, etc... There is no form on this page... it''s just

Hello Xenoprof Users, Can someone please verify the steps to get a oprofile session profile multiple sessions? I am using a file VBD for spawning two guest OS domains on the host. I am doing the following: 1.) On dom0 Opcontrol --xen=/boot/xen-syms-blah 2.) On domU domID: 41 Opcontrol --vmlinux=/boot/vmlinux-2..blah 3.) On domU domID: 42 Opcontrol

Hi! I am trying to profile my custom 2.6.37 linux kernel with oprofile in centos 5.5, and i have encountered the following problem. (Before everyone starts shouting, I know that custom kernels are not supported by centos team, however I really need to run a modified version, due to a project concerning my MSc thesis. So i hope for your understanding :-) . I have build the kernel

Hi I am trying to use oprofile with centos 6.0. I know that the debug-info for the kernel is not available, so I believe I used the correct switches to account for this. here is my script... # reset everything opcontrol --shutdown rm /root/.oprofile/da* opcontrol --separate=kernel --no-vmlinux opcontrol --event=CPU_CLK_UNHALTED:100000 opcontrol --start sleep 5

Hi all, Is anyone using oprofile? I'm getting segfaults from opreport at the moment, and I'm not sure if it is opreport, or just me. In case it is something just plain daft I am doing, here is how it goes: opcontrol --reset opcontrol --setup --no-vmlinux opcontrol --start ... now I run my program, /tmp/myprog ... opcontrol --dump opcontrol --shutdown then I run, opreport -l

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

Dear experts, to monitor performance of applications on our private clouds I decided to use Xenoprof. For that, I installed patched OProfile 0.9.5 on Dom0 and DomU. Then, I started the daemon on Dom0 opcontrol --start-daemon --active-domains=1 --separate=library --event=LLC_MISSES:90000 and received the following error: /usr/local/bin/opcontrol: line 1171: echo write error: invalid

Hi all, I am trying to do Xen / Kernel profiling. So I tried passive domain profile with oprofile tool in Dom0 as below. * Environment 1 + i7-2600 CPU + XCP 1.6 Base ISO + CentOS 6.3 Guest (HVM,PV) * Environment 2 + i7-2600 CPU + Xen hypervisor 4.2.1 + Konrad''s passive domain profiling patch applied Dom0 Kernel ( 2.6.32 jeremy branch & 3.2.44 mainline kernel) + CentOS 6.3

So, we just moved to some much faster hardware. intel q6600 CPU, 8Gb unbuffered ECC, ICH7 sata (2x1TB disks) - and we were irritated and puzzled to find that the new setup had really, really slow I/O. The odd thing is that the performance is fine if you just mount the LV directly from the Dom0... but if you xm block-attach it to the Dom0 and then mount it, you get 1/10th the speed. we are

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, 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 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

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 got the message "Using timer interrupt." when trying the command "opcontrol --list-events". then I found infomation "xenoprof: Initialization failed. Intel processor model 44 for P6 class family is not supported“ after "xm dmesg". the TYPE OF CPUS here is Intel(R) Xeon(R) CPU E5620 @ 2.40GHz. So does it really not support this

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
