similar to: Oprofile in unsupported kernel?

Two related questions. 1. When is the unsupported version of 2.6.9.22 likely to be available? ?? I need to access reiser filesystems so I?m currently running on the .11unsupported kernel. 2. Has anyone successfully compiled reiser into the 2.6.9.22 kernel? ???I am getting errors in stree.c but I can?t find a solution on the net? Thanks Daveh

I would like to rebuild glibc specifically with the -mno-tls-direct-seg-refs to allow better performance with Xen. I'm using Centos 4.2 x86_64 on an Athlon 3200+. I'm using the 2.6.9-11.106.unsupported kernel for reiser support. My thought was to download and install the SRPM and then rpmbuild with no changes to make sure it works before adding the above flag. Unfortunately, the

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'm new to Dovecot so please be gentle with me. I did a search through the list archives but couldn't quite work out my problem. I have Dovecot installed and running and I can connect to it from my email clients (Outlook and Evolution) ... so looking good so far. I would like to setup three types (groups?) of mail store 1. A per user - e.g. Fred, Harry, Betty. (For my purposes they

Nicolas Thierry-Mieg, We followed your instructions to yum install oprofile-gui. We were able to install oprofile-guii.i386 0:0.9.4-15.el5.centos and oprofile.i386 0.0.9.4.15.el.5.centos. I was wondering what our next step should be. I tried ./configure --with-kernel-support with oprofile-0.9.6 and obtain a warning, a working QT not found, no GUI was built. Should we try to build

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 all again, I found this kernel panic past days, now using the unsuported kernel and comes out again the same error. This time on '2.6.9-22.0.1.106.unsupported' kernel See attached logs, Env is the same with the same box, Hope it helps. TIA.

The attached patch fixes a Xen panic when a domain is shutdown before oprofile is stopped. Without this patch, free_xenoprof_pages() is called before the domain is destroyed and that, in turn, prevents oprofile from cleaning up pages shared with guests. Shutting down a domain without terminating oprofile therefore causes a Xen panic at a later point in time. The patch was generated against Xen

Hi, I have tried to profile xapian, according to the Wiki: http://trac.xapian.org/wiki/ProfilingXapian, we can profiling I/O bound cases with oprofile, but from many other articles, it seems that we can not do it in oprofile. I have followed that wiki page, installed oprofile and libc6-dbg, but it doesn't work, only CPU bound functions are counted. Anyone know how to count I/O cost in

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

Philip Schaffner, Thank you for your reply. I guess we will have to wait until Centos 6 arrives to get a working QT. Did you see Nicolas Thierry-Mieg's response regarding yum install oprofile-gui. We were able to install oprofile-guii.i386 0:0.9.4-15.el5.centos and oprofile.i386 0.0.9.4.15.el.5.centos. Thank you. -------------- next part -------------- An HTML attachment was

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 Keir: It has been brought to my attention that modular oprofile is broken because it now calls get_vm_area which is not an exported function. This appears to be the result of the changeset that removed vm_map_xen_pages which was only used by oprofile. So we either need to export get_vm_area in Xen, or put that function back. What do you think about this? Thanks, -- Visit Openswan at

Hi, as now i am doing profiling and found that the QEMU should be one of the major reason for the low network throughput on HVM Guest. In order to know details about it, it will be better to get the breakdown of QEMU in Oprofile. As see from the following results,there is only two breakdowns, how can I run the oprofile to get more detailed QEMU informations? 29933 12.5726 qemu-dm

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

Hello, After booting the xen-stable 2.6.32.10 pv_ops kernel from jeremy git tree with Xen-4.0.0-rc8 installed, dmesg | grep PMU shows : Performance Events : unsupported p6 CPU model 26 no PMU driver, software events only. PMU:oprofile: found i386/core_i7. If I boot the same compiled kernel, without Xen installed, dmesg | grep PMU shows : Performance Events : Nehalem/Corei7 events, Intel

Hi all, Firstly if this is a FAQ and I've missed it - let me apologise in advance. I use dovecot as a backup mail store and would now like to purge all mails over a certain age. Is it as simple as using find and rm'ing the results or is there more to it? I'm using maildir if that make a difference? Thanks in advance. Daveh

Hi A search of google failed to show any prebuilt rpms for sshfs and fuse. I do see that fuse support is in 2.6.14 kernel which isn't a whole lot of help. Before I dive headlong into this has anyone successfully built fuse/sshfs against Centos 4.4. If so would you share your experience? Thanks Daveh
