This is based on v7 of the full Haswell PMU support, but ported to the latest perf/core and stripped down to the "basic support" as requested.
I decided to include LBRs in the basic support. These are 4 patches self contained at the end, so could be also handled as a separate unit if that is preferable.
Contains support for: - Basic Haswell PMU and PEBS support - Late unmasking of the PMI - Support for wide counters - New TSX counter flags, exported as sysfs attributes - Support for checkpointed counters. - New LBR flags, exported as new flags with tools support
Available from git://git.kernel.org/pub/scm/linux/kernel/git/ak/linux-misc hsw/pmu4-basics
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
