Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent

Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

User visible changes:

* Add a visual cue for toggle zeroing of samples in 'perf top' (Taeung Song)

* Fix for double free in 'perf stat' when using some specific invalid
command line combo (Yasser Shalabi)

Infrastructure changes:

* Add option to copy events when queuing for sorting across cpu buffers
and enable it for 'perf kvm stat live', to avoid having events left
in the queue pointing to the ring buffer be rewritten in high volume
sessions. (Alexander Yarygin, improving work done by David Ahern):

* Document sysfs events/ interfaces (Cody P Schafer)

* Add support to new style format of kernel PMU event. (Kan Liang)

* Fix typos in perf/Documentation (Masanari Iida)

* Improve callchains when using libunwind (Namhyung Kim)

perf tools: Add support to new style format of kernel PMU event

Add new rules for kernel PMU event.

Currently, the patch only want to handle the PMU event name as "a-b" and
"a".

event_pmu:
PE_KERNEL_PMU_EVENT sep_dc
|
PE_PMU_EVENT_PRE '-' PE_PMU_EVENT_SUF sep_dc

PE_KERNEL_PMU_EVENT token is for
cycles-ct/cycles-t/mem-loads/mem-stores.

The prefix cycles is mixed up with cpu-cycles. loads and stores are
mixed up with cache event So they have to be hardcode in lex.

PE_PMU_EVENT_PRE and PE_PMU_EVENT_SUF tokens are for other PMU events.

The lex looks generic identifier up in the table and return the matched
token. If there is no match, generic PE_NAME token will be return.

Using the rules, kernel PMU event could use new style format without //

so you can use:

perf record -e mem-loads ...

instead of:

perf record -e cpu/mem-loads/

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

. 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

. 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.

Arnaldo Carvalho de Melo.

. Implement more compact 'trace' output by suppressing zeroed

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.

. 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

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!"
