Subject: perf PMU support for Haswell
Date: Thu, 27 Sep 2012 21:31:05 -0700 [thread overview]
Message-ID: <1348806696-31170-1-git-send-email-andi@firstfloor.org> (raw)
This adds perf PMU support for the upcoming Haswell core. The patchkit
is fairly large, mainly due to various enhancement for TSX. TSX tuning
relies heavily on the PMU, so I tried hard to make all facilities
easily available. In addition it also has some other enhancements.
This includes changes to the core perf code, to the x86 specific part,
to the perf user land tools and to KVM
High level overview:
- Basic Haswell PMU support
- Easy high level TSX measurement in perf stat -T
- Generic transactional memory events, plus Haswell implementations.
- Generic weightend profiling for memory latency and transaction abort costs.
- Support for address profiling
- Support for filtering events inside/outside transactions
- KVM support to do this from guests
- Support for filtering/sorting/bucketing transaction abort types based on
PEBS information
- LBR support for transactions
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
Review appreciated.
-Andi
