From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en; rv:1.8.1.5) Gecko/20061201 Epiphany/2.18 Firefox/2.0.0.5 (Ubuntu-feisty) Description of problem: After installing pfmon (pfmon-3.2-0.060926.4.el5) and libpfm (libpfm-3.2-0.060926.4.el5) when I then run pfmon I get :host kernel does not have perfmon support When I check the kernel config file the "cat /boot/config-2.6.18-8.el5 |grep -i PERFMON" I get nothing. There should be a line saying "CONFIG_PERFMON=y" which isn't there. It has been a request from the performance team to have the availability of that tool on all RHEL 5 systems on i386 and x86_64 too since it's included in the distribution. Since we're not allowed to recompile the kernel since we need to be sure we are testing on the default kernel we are currently not able to add the functionality for them. As these packages are included in the distribution I guess that this is a bug. ./ia32/RHEL5/Server/pfmon-3.2-0.060926.4.el5.i386.rpm ./x86_64/RHEL5/Server/pfmon-3.2-0.060926.4.el5.x86_64.rpm Version-Release number of selected component (if applicable): pfmon-3.2-0.060926.4.el5 kernel-2.6.18-8.el5 How reproducible: Always Steps to Reproduce: 1. rpm -ivh pfmon-3.2-0.060926.4.el5.i386.rpm libpfm-3.2-0.060926.4.el5.i386.rpm 2.[root@localhost ~]# pfmon host kernel does not have perfmon support Same goes for x86_64 systems Actual Results: host kernel does not have perfmon support Expected Results: This package contains pfmon 3.x, a tool to monitor performance using the Performance Monitor Unit (PMU). Pfmon can monitor standalone programs or the entire system on both UP and SMP Linux systems. Additional info:
*** Bug 250247 has been marked as a duplicate of this bug. ***
There is development on perfmon2 to provide support for architectures other than ia64 supported in the original perfmon kernel support. However, need to have the perfmon2 support for x86_64 and i386 merged with the upstream linux kernels before backporting it to the Red Hat Enterprise Linux kernels.

The bug that this is marked as a duplicate of is not visible to the public. Has there been any resolution?
Not that I know of. But this is still interesting. Any chance of getting access to the bug that is currently unavailable?
The summary of the 447621 is that RHEL6 support perf, the performance counter mechanism in the newer Linux kernels. https://perf.wiki.kernel.org/index.php/Main_Page http://lwn.net/Articles/310176/ There is similar support in Fedora 12 with the installation of the perf RPM.
