Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf updates from Ingo Molnar:
"Kernel side updates:
- Fix and enhance poll support (Jiri Olsa)
- Re-enable inheritance optimization (Jiri Olsa)
- Enhance Intel memory events support (Stephane Eranian)
- Refactor the Intel uncore driver to be more maintainable (Zheng
Yan)
- Enhance and fix Intel CPU and uncore PMU drivers (Peter Zijlstra,
Andi Kleen)
- [ plus various smaller fixes/cleanups ]
User visible tooling updates:
- Add +field argument support for --field option, so that one can add
fields to the default list of fields to show, ie now one can just
do:
perf report --fields +pid
And the pid will appear in addition to the default fields (Jiri
Olsa)
- Add +field argument support for --sort option (Jiri Olsa)
- Honour -w in the report tools (report, top), allowing to specify
the widths for the histogram entries columns (Namhyung Kim)
- Properly show submicrosecond times in 'perf kvm stat' (Christian
Borntraeger)
- Add beautifier for mremap flags param in 'trace' (Alex Snast)
- perf script: Allow callchains if any event samples them
- Don't truncate Intel style addresses in 'annotate' (Alex Converse)
- Allow profiling when kptr_restrict == 1 for non root users, kernel
samples will just remain unresolved (Andi Kleen)
- Allow configuring default options for callchains in config file
(Namhyung Kim)
- Support operations for shared futexes. (Davidlohr Bueso)
- "perf kvm stat report" improvements by Alexander Yarygin:
- Save pid string in opts.target.pid
- Enable the target.system_wide flag
- Unify the title bar output
- [ plus lots of other fixes and small improvements. ]
Tooling infrastructure changes:
- Refactor unit and scale function parameters for PMU parsing
routines (Matt Fleming)
- Improve DSO long names lookup with rbtree, resulting in great
speedup for workloads with lots of DSOs (Waiman Long)
- We were not handling POLLHUP notifications for event file
descriptors
Fix it by filtering entries in the events file descriptor array
after poll() returns, refcounting mmaps so that when the last fd
pointing to a perf mmap goes away we do the unmap (Arnaldo Carvalho
de Melo)
- Intel PT prep work, from Adrian Hunter, including:
- Let a user specify a PMU event without any config terms
- Add perf-with-kcore script
- Let default config be defined for a PMU
- Add perf_pmu__scan_file()
- Add a 'perf test' for tracking with sched_switch
- Add 'flush' callback to scripting API
- Use ring buffer consume method to look like other tools (Arnaldo
Carvalho de Melo)
- hists browser (used in top and report) refactorings, getting rid of
unused variables and reducing source code size by handling similar
cases in a fewer functions (Namhyung Kim).
- Replace thread unsafe strerror() with strerror_r() accross the
whole tools/perf/ tree (Masami Hiramatsu)
- Rename ordered_samples to ordered_events and allow setting a queue
size for ordering events (Jiri Olsa)
- [ plus lots of fixes, cleanups and other improvements ]"
