Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf updates from Ingo Molnar: "As a first remark I'd like to note that the way to build perf tooling has been simplified and sped up, in the future it should be enough for you to build perf via:
cd tools/perf/ make install
(ie without the -j option.) The build system will figure out the number of CPUs and will do a parallel build+install.
The various build system inefficiencies and breakages Linus reported against the v3.12 pull request should now be resolved - please (re-)report any remaining annoyances or bugs.
Main changes on the perf kernel side:
* Performance optimizations: . perf ring-buffer code optimizations, by Peter Zijlstra . perf ring-buffer code optimizations, by Oleg Nesterov . x86 NMI call-stack processing optimizations, by Peter Zijlstra . perf context-switch optimizations, by Peter Zijlstra . perf sampling speedups, by Peter Zijlstra . x86 Intel PEBS processing speedups, by Peter Zijlstra
* Enhanced hardware support: . for Intel Ivy Bridge-EP uncore PMUs, by Zheng Yan . for Haswell transactions, by Andi Kleen, Peter Zijlstra
* Core perf events code enhancements and fixes by Oleg Nesterov: . for uprobes, if fork() is called with pending ret-probes . for uprobes platform support code
* New ABI details by Andi Kleen: . Report x86 Haswell TSX transaction abort cost as weight
Main changes on the perf tooling side (some of these tooling changes utilize the above kernel side changes):
* 'perf report/top' enhancements:
. Convert callchain children list to rbtree, greatly reducing the time taken for callchain processing, from Namhyung Kim.
. Add new COMM infrastructure, further improving histogram processing, from Frédéric Weisbecker, one fix from Namhyung Kim.
. Add /proc/kcore based live-annotation improvements, including build-id cache support, multi map 'call' instruction navigation fixes, kcore address validation, objdump workarounds. From Adrian Hunter.
. Show progress on histogram collapsing, that can take a long time, from Namhyung Kim.
. Add --max-stack option to limit callchain stack scan in 'top' and 'report', improving callchain processing when reducing the stack depth is an option, from Waiman Long.
. Add new option --ignore-vmlinux for perf top, from Willy Tarreau.
* 'perf trace' enhancements:
. 'perf trace' now can can use a 'perf probe' dynamic tracepoints to hook into the userspace -> kernel pathname copy so that it can map fds to pathnames without reading /proc/pid/fd/ symlinks. From Arnaldo Carvalho de Melo.
. Show VFS path associated with fd in live sessions, using a 'vfs_getname' 'perf probe' created dynamic tracepoint or by looking at /proc/pid/fd, from Arnaldo Carvalho de Melo.
. Add 'trace' beautifiers for lots of syscall arguments, from Arnaldo Carvalho de Melo.
. Implement more compact 'trace' output by suppressing zeroed args, from Arnaldo Carvalho de Melo.
. Show thread COMM by default in 'trace', from Arnaldo Carvalho de Melo.
. Add option to show full timestamp in 'trace', from David Ahern.
. Add 'record' command in 'trace', to record raw_syscalls:*, from David Ahern.
. Add summary option to dump syscall statistics in 'trace', from David Ahern.
. Improve error messages in 'trace', providing hints about system configuration steps needed for using it, from Ramkumar Ramachandra.
. 'perf trace' now emits hints as to why tracing is not possible, helping the user to setup the system to allow tracing in the desired permission granularity, telling if the problem is due to debugfs not being mounted or with not enough permission for !root, /proc/sys/kernel/perf_event_paranoit value, etc. From Arnaldo Carvalho de Melo.
* 'perf record' enhancements:
. Check maximum frequency rate for record/top, emitting better error messages, from Jiri Olsa.
. 'perf record' code cleanups, from David Ahern.
. Improve write_output error message in 'perf record', from Adrian Hunter.
. Allow specifying B/K/M/G unit to the --mmap-pages arguments, from Jiri Olsa.
. Fix command line callchain attribute tests to handle the new -g/--call-chain semantics, from Arnaldo Carvalho de Melo.
* 'perf kvm' enhancements:
. Disable live kvm command if timerfd is not supported, from David Ahern.
. Fix detection of non-core features, from David Ahern.
* 'perf list' enhancements:
. Add usage to 'perf list', from David Ahern.
. Show error in 'perf list' if tracepoints not available, from Pekka Enberg.
* 'perf probe' enhancements:
. Support "$vars" meta argument syntax for local variables, allowing asking for all possible variables at a given probe point to be collected when it hits, from Masami Hiramatsu.
* 'perf sched' enhancements:
. Address the root cause of that 'perf sched' stack initialization build slowdown, by programmatically setting a big array after moving the global variable back to the stack. Fix from Adrian Hunter.
* 'perf script' enhancements:
. Set up output options for in-stream attributes, from Adrian Hunter.
. Print addr by default for BTS in 'perf script', from Adrian Juntmer
* 'perf stat' enhancements:
. Improved messages when doing profiling in all or a subset of CPUs using a workload as the session delimitator, as in:
'perf stat --cpu 0,2 sleep 10s'
from Arnaldo Carvalho de Melo.
. Add units to nanosec-based counters in 'perf stat', from David Ahern.
. Remove bogus info when using 'perf stat' -e cycles/instructions, from Ramkumar Ramachandra.
* 'perf lock' enhancements:
. 'perf lock' fixes and cleanups, from Davidlohr Bueso.
* 'perf test' enhancements:
. Fixup PERF_SAMPLE_TRANSACTION handling in sample synthesizing and 'perf test', from Adrian Hunter.
. Clarify the "sample parsing" test entry, from Arnaldo Carvalho de Melo.
. Consider PERF_SAMPLE_TRANSACTION in the "sample parsing" test, from Arnaldo Carvalho de Melo.
. Memory leak fixes in 'perf test', from Felipe Pena.
* 'perf bench' enhancements:
. Change the procps visible command-name of invididual benchmark tests plus cleanups, from Ingo Molnar.
* Generic perf tooling infrastructure/plumbing changes:
. Separating data file properties from session, code reorganization from Jiri Olsa.
. Fix version when building out of tree, as when using one of these:
$ make help | grep perf perf-tar-src-pkg - Build perf-3.12.0.tar source tarball perf-targz-src-pkg - Build perf-3.12.0.tar.gz source tarball perf-tarbz2-src-pkg - Build perf-3.12.0.tar.bz2 source tarball perf-tarxz-src-pkg - Build perf-3.12.0.tar.xz source tarball $
from David Ahern.
. Enhance option parse error message, showing just the help lines of the options affected, from Namhyung Kim.
. libtraceevent updates from upstream trace-cmd repo, from Steven Rostedt.
. Always use perf_evsel__set_sample_bit to set sample_type, from Adrian Hunter.
. Memory and mmap leak fixes from Chenggang Qin.
. Assorted build fixes for from David Ahern and Jiri Olsa.
. Speed up and prettify the build system, from Ingo Molnar.
. Implement addr2line directly using libbfd, from Roberto Vitillo.
. Separate the GTK support in a separate libperf-gtk.so DSO, that is only loaded when --gtk is specified, from Namhyung Kim.
. perf bash completion fixes and improvements from Ramkumar Ramachandra.
. Support for Openembedded/Yocto -dbg packages, from Ricardo Ribalda Delgado.
And lots and lots of other fixes and code reorganizations that did not make it into the list, see the shortlog, diffstat and the Git log for details!"

Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf changes from Ingo Molnar: "There are lots of improvements, the biggest changes are:
Main kernel side changes:
- Improve uprobes performance by adding 'pre-filtering' support, by Oleg Nesterov.
- Make some POWER7 events available in sysfs, equivalent to what was done on x86, from Sukadev Bhattiprolu.
- tracing updates by Steve Rostedt - mostly misc fixes and smaller improvements.
- Use perf/event tracing to report PCI Express advanced errors, by Tony Luck.
- Enable northbridge performance counters on AMD family 15h, by Jacob Shin.
- This tracing commit:
tracing: Remove the extra 4 bytes of padding in events
changes the ABI. All involved parties (PowerTop in particular) seem to agree that it's safe to do now with the introduction of libtraceevent, but the devil is in the details ...
Main tooling side changes:
- Add 'event group view', from Namyung Kim:
To use it, 'perf record' should group events when recording. And then perf report parses the saved group relation from file header and prints them together if --group option is provided. You can use the 'perf evlist' command to see event group information:
$ perf record -e '{ref-cycles,cycles}' noploop 1 [ perf record: Woken up 2 times to write data ] [ perf record: Captured and wrote 0.385 MB perf.data (~16807 samples) ]
$ perf evlist --group {ref-cycles,cycles}
With this example, default perf report will show you each event separately.
You can use --group option to enable event group view:
$ perf report --group ... # group: {ref-cycles,cycles} # ======== # Samples: 7K of event 'anon group { ref-cycles, cycles }' # Event count (approx.): 6876107743 # # Overhead Command Shared Object Symbol # ................ ....... ................. .......................... 99.84% 99.76% noploop noploop [.] main 0.07% 0.00% noploop ld-2.15.so [.] strcmp 0.03% 0.00% noploop [kernel.kallsyms] [k] timerqueue_del 0.03% 0.03% noploop [kernel.kallsyms] [k] sched_clock_cpu 0.02% 0.00% noploop [kernel.kallsyms] [k] account_user_time 0.01% 0.00% noploop [kernel.kallsyms] [k] __alloc_pages_nodemask 0.00% 0.00% noploop [kernel.kallsyms] [k] native_write_msr_safe 0.00% 0.11% noploop [kernel.kallsyms] [k] _raw_spin_lock 0.00% 0.06% noploop [kernel.kallsyms] [k] find_get_page 0.00% 0.02% noploop [kernel.kallsyms] [k] rcu_check_callbacks 0.00% 0.02% noploop [kernel.kallsyms] [k] __current_kernel_time
As you can see the Overhead column now contains both of ref-cycles and cycles and header line shows group information also - 'anon group { ref-cycles, cycles }'. The output is sorted by period of group leader first.
- Initial GTK+ annotate browser, from Namhyung Kim.
- Add option for runtime switching perf data file in perf report, just press 's' and a menu with the valid files found in the current directory will be presented, from Feng Tang.
- Add support to display whole group data for raw columns, from Jiri Olsa.
- Add per processor socket count aggregation in perf stat, from Stephane Eranian.
- Add interval printing in 'perf stat', from Stephane Eranian.
- 'perf test' improvements
- Add support for wildcards in tracepoint system name, from Jiri Olsa.
- Add anonymous huge page recognition, from Joshua Zhu.
- perf build-id cache now can show DSOs present in a perf.data file that are not in the cache, to integrate with build-id servers being put in place by organizations such as Fedora.
- perf top now shares more of the evsel config/creation routines with 'record', paving the way for further integration like 'top' snapshots, etc.
- perf top now supports DWARF callchains.
- Fix mmap limitations on 32-bit, fix from David Miller.
- 'perf bench numa mem' NUMA performance measurement suite
- ... and lots of fixes, performance improvements, cleanups and other improvements I failed to list - see the shortlog and git log for details."

perf gtk/annotate: Support multiple event annotation
Show multiple annotation result for each evsel. Each result represents the most frquently sampled symbol/function for the evsel and it will be shown in a tab window.
For this add a reference to main container (notebook) to the pgctx. At the first call to annotate browser, hist_entry__find_annotations() will setup a new browser, and next calls will add new tabs to the browser. But it requires final perf_gtk__show_annotations() to start processing GUI events.
