Subject: Basic perf PMU support for Haswell v1
Newsgroups: gmane.linux.kernel
Date: Friday 25th January 2013 22:00:33 UTC (over 3 years ago)
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
