This option is no longer supported with OProfile 0.9.8 and higher. For 2.6 or higher kernels, ensure that the kernel has been configured to include OProfile, either built into the kernel or as a module. Next, do ./configure --with-kernel-support.

Featured are Pentium 4 support, and support for the new 2.5 kernel support. There are also a significant number of important bug fixes. Users are encouraged to upgrade. 2002-10-16 OProfile merged in 2.5.43. The 2.5 rewrite of OProfile has merged in the 2.5.43 development kernel release.

An OProfile kernel driver, usually built as a kernel module, is used for collecting samples, which are then recorded into sample files by oprofiled. You can use legacy mode only if you have root privileges. In certain cases, such as when you need to sample areas with disabled interrupt request (IRQ), this is a better alternative.

In computing, OProfile is a system-wide statistical profiling tool for Linux.John Levon wrote it in 2001 for Linux kernel version 2.4 after his M.Sc. project; it consists of a kernel module, a user-space daemon and several user-space tools.. OProfile can profile an entire system or its parts, from interrupt routines or drivers, to user-space processes.It has low overhead.License: GPL

The attached patch extends OProfile's Cell support (committed into 2.6.20-rc1), adding the capability to do time-based profiling of the SPUs. This is a preliminary patch we're posting for comments.

Before OProfile can be run, it must be configured. At a minimum, selecting to monitor the kernel (or selecting not to monitor the kernel) is required. The following sections describe how to use the opcontrol utility to configure OProfile. As the opcontrol commands are executed, the setup options are saved to the /root/.oprofile/daemonrc file.

Analyzing the performance of the Linux operating system and application code can be difficult due to unexpected interactions between the hardware and the software, but profiling is one way you can identify such performance problems. This article looks at OProfile, a profiling tool for Linux that will be included in the upcoming stable kernel.
