Subject: [GIT PULL] perf changes for v4.13
Linus,
Please pull the latest perf-core-for-linus git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git perf-core-for-linus
# HEAD: 23acd3e1a0a377cf3730ccb753aa1fdc50378396 Merge tag 'perf-core-for-mingo-4.13-20170630' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core
Most of the changes are for tooling, the main changes in this cycle were:
- Improve Intel-PT hardware tracing support, both on the kernel and on the
tooling side: PTWRITE instruction support, power events for C-state tracing,
etc. (Adrian Hunter)
- Add support to measure SMI cost to the x86 architecture, with tooling support
in 'perf stat' (Kan Liang)
- Support function filtering in 'perf ftrace', plus related improvements
(Namhyung Kim)
- Allow adding and removing fields to the default 'perf script' columns,
using + or - as field prefixes to do so (Andi Kleen)
- Allow resolving the DSO name with 'perf script -F brstack{sym,off},dso'
(Mark Santaniello)
- Add perf tooling unwind support for PowerPC (Paolo Bonzini)
- ... and various other improvements as well.
Thanks,
Ingo
