Hello, Perfmon2 is a new kernel subsystem which provides access to the hardware performance counters of modern processors. It supports basic counting and sampling on a per-thread or system-wide basis. Most major processor architectures are supported.
The following series of patches includes the perfmon2 subsystem and the support for i386, x86_64, various mips, and powerpc. The perfmon2 subsystem also works on all Itanium processors, yet the Itanium patches are not posted on LKML due to the 100k message. They can be provided separately. The powerpc (Power5) support is still preliminary. The patches are relative to 2.6.22-rc3 I have already posted on the list about this subsystem. The code has already been reviewed last year and lots of changes were made. I am resubmitting today for a final review before perfmon2 gets merged with mainline kernel. The patches are split up for easier reading. The split is by functionality for the common code. The per-architecture code is split between modified and new files. For each group of patches (separate message), a short description of what they do is provided. This codebase represents the work of many people beyond just me and I'd like to thank them publicly for their valuable contributions to this project. Thanks. -- -Stephane - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
