This release is relative to 2.6.15-rc5-git3. I have also updated the library, libpfm-3.2, to match the kernel level changes. This new kernel patch includes several important changes: - pfm_create_context() interface has changed. The sampling buffer format argument is now passed explicitly instead of relying on it being contiguous to pfarg_ctx_t. - code in perfmon/perfmon.c has been split into 8 different files for improved maintainability. Each file implements one specific function. Perfmon.c remains the core. - fixed several important bugs for i386 and x86_64 for Intel P4/Xeon (simple counting was returning 0). - added support for virtual PMD (read/write) - added notion of read-only PMD - Split Pentium M/P 6 PMU description in preparation for Pentium M LBR support - Added support for reference counting on PMU description and Sampling buffer modules to avoid panic in case module is removed while being used. - On i386/X86_64, added code to handle the NMI watchdog when it is using the Local APIC. We now use reserve_lapic_nmi() and release_lapic_nmi(). - various other cleanups and bug fixes You MUST use libpfm-3.2-051215 with this kernel due to interface change for pfm_create_context(). As usual, you can download the latest packages from the SourceForge website at: http://www.sf.net/projects/perfmon2 I will be posting the patches directly to LKML for review very shortly. Enjoy, -- -Stephane
