Appendix B. Installing oprofileAlthough the system profiler oprofile is a powerful performance tool, its installation/use can be tricky. This appendix describes some of the issues when installing oprofile on Fedora Core 2 (FC2), Red Hat Enterprise Linux (EL3), and SUSE 9.1 (S9.1). |
B.1 Fedora Core 2 (FC2)For FC2, Red Hat provides packages for oprofile that should be used rather than those downloaded from the oprofile Web site. The uniprocessor kernel does not provide the necessary oprofile drivers. Red Hat packages the necessary oprofile kernel modules with the smp version of the kernel. If you want to run oprofile , you must use the smp kernel, even if you are running it on a single-processor machine. |
B.2 Enterprise Linux 3 (EL3)For EL3, once again, Red Hat provides packages for oprofile that should be used rather than those downloaded from the oprofile Web site. The uniprocessor kernel does not provide the necessary oprofile drivers. Red Hat packages the necessary oprofile kernel modules with the smp or hugemem versions of the kernel. If you want to run oprofile , you must use the smp or hugemem kernel, even if you are running it on a single-processor machine. More details on using oprofile in EL3 are provided at http://www.redhat.com/docs/manuals/enterprise/RHEL-3-Manual/sysadmin-guide/ch-oprofile.html. |
B.3 SUSE 9.1For SUSE 9.1, SUSE provides packages for oprofile that should be used rather than those downloaded from the oprofile Web site. All versions of the SUSE kernels ( default , smp , and bigsmp ) provide support for oprofile , so any of the supplied kernels will work. |
