This is based on v7 of the earlier combined Haswell PMU patchkit. The basic functionality has moved into a separate patchkit. These patches implement more advanced functionality. Most of the functionality is related to TSX.
This applies on top of the basic hsw/pmu4-basics patchkit posted separately. Some of this touches similar areas as Stephane's patchkit, with some shared patches too. Available at git://git.kernel.org/pub/scm/linux/kernel/ak/linux-misc.git hsw/pmu4 High level overview: - Easy high level TSX measurement in perf stat -T - Transaction events and attributes implemented with sysfs enumeration - Export arch perfmon events in sysfs - Generic weightend profiling for memory latency and transaction abort costs. - Support for address profiling - KVM support to do basic TSX profiling from guests - Support for filtering/displaying transaction abort types based on PEBS information For more details on the Haswell PMU please see the SDM. For more details on TSX please see http://halobates.de/adding-lock-elision-to-linux.pdf Some of the added features could be added to older CPUs too. I plan to do this, but in separate patches. Open: - Weight sorting does not work (see thread), not a show stopper. -Andi -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
