Subject: Basic perf PMU support for Haswell v1
Date: Fri, 25 Jan 2013 14:00:33 -0800 [thread overview]
Message-ID: <1359151245-13179-1-git-send-email-andi@firstfloor.org> (raw)
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
