Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull perf updates from Ingo Molnar:
"The main kernel side changes were:

- Modernize the kprobe and uprobe creation/destruction tooling ABIs:

The existing text based APIs (kprobe_events and uprobe_events in
tracefs), are naive, limited ABIs in that they require user-space
to clean up after themselves, which is both difficult and fragile
if the tool is buggy or exits unexpectedly. In other words they are
not really suited for modern, robust tooling.

So introduce a modern, file descriptor based ABI that does not have
these limitations: introduce the 'perf_kprobe' and 'perf_uprobe'
PMUs and extend the perf_event_open() syscall to create events with
a kprobe/uprobe attached to them. These [k,u]probe are associated
with this file descriptor, so they are not available in tracefs.

(Song Liu)

- Intel Cannon Lake CPU support (Harry Pan)

- Intel PT cleanups (Alexander Shishkin)

- Improve the performance of pinned/flexible event groups by using RB
trees (Alexey Budankov)

- Add PERF_EVENT_IOC_MODIFY_ATTRIBUTES which allows the modification
of hardware breakpoints, which new ABI variant massively speeds up
existing tooling that uses hardware breakpoints to instrument (and
debug) memory usage.

(Milind Chabbi, Jiri Olsa)

- Various Intel PEBS handling fixes and improvements, and other Intel
PMU improvements (Kan Liang)

- Various perf core improvements and optimizations (Peter Zijlstra)

- ... misc cleanups, fixes and updates.

There's over 200 tooling commits, here's an (imperfect) list of
highlights:

- 'perf annotate' improvements:

* Recognize and handle jumps to other functions as calls, which
improves the navigation along jumps and back. (Arnaldo Carvalho
de Melo)

* Add the 'P' hotkey in TUI annotation to dump annotation output
into a file, to ease e-mail reporting of annotation details.
(Arnaldo Carvalho de Melo)

* Add an IPC/cycles column to the TUI (Jin Yao)

* Improve s390 assembly annotation (Thomas Richter)

* Refactor the output formatting logic to better separate it into
interactive and non-interactive features and add the --stdio2
output variant to demonstrate this. (Arnaldo Carvalho de Melo)

- 'perf script' improvements:

* Add Python 3 support (Jaroslav Škarvada)

* Add --show-round-event (Jiri Olsa)

- 'perf c2c' improvements:

* Add NUMA analysis support (Jiri Olsa)

- 'perf trace' improvements:

* Improve PowerPC support (Ravi Bangoria)

- 'perf inject' improvements:

* Integrate ARM CoreSight traces (Robert Walker)

- 'perf stat' improvements:

* Add the --interval-count option (yuzhoujian)

* Add the --timeout option (yuzhoujian)

- 'perf sched' improvements (Changbin Du)

- Vendor events improvements :

* Add IBM s390 vendor events (Thomas Richter)

* Add and improve arm64 vendor events (John Garry, Ganapatrao
Kulkarni)

* Update POWER9 vendor events (Sukadev Bhattiprolu)

- Intel PT tooling improvements (Adrian Hunter)

- PMU handling improvements (Agustin Vega-Frias)

- Record machine topology in perf.data (Jiri Olsa)

- Various overwrite related cleanups (Kan Liang)

- Add arm64 dwarf post unwind support (Kim Phillips, Jean Pihet)

- ... and lots of other changes, cleanups and fixes, see the shortlog
and Git history for details"

using cgroup__{put,get} for refcount operations instead of its

strace like tracing (plus other events, backtraces, etc) for cgroups
(Arnaldo Carvalho de Melo)

Merge tag 'perf-core-for-mingo-4.17-20180305' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

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

- Be more robust when drawing arrows in the annotation TUI, avoiding a
segfault when jump instructions have as a target addresses in functions
other that the one currently being annotated. The full fix will come in
the following days, when jumping to other functions will work as call
instructions (Arnaldo Carvalho de Melo)

- Allow asking for the maximum allowed sample rate in 'top' and
'record', i.e. 'perf record -F max' will read the
kernel.perf_event_max_sample_rate sysctl and use it (Arnaldo Carvalho de Melo)

- When the user specifies a freq above kernel.perf_event_max_sample_rate,
Throttle it down to that max freq, and warn the user about it, add as
well --strict-freq so that the previous behaviour of not starting the
session when the desired freq can't be used can be selected (Arnaldo Carvalho de Melo)

- Find 'call' instruction target symbol at parsing time, used so far in
the TUI, part of the infrastructure changes that will end up allowing
for jumps to navigate to other functions, just like 'call'
instructions. (Arnaldo Carvalho de Melo)

- Use xyarray dimensions to iterate fds in 'perf stat' (Andi Kleen)

- Ignore threads for which the current user hasn't permissions when
enabling system-wide --per-thread (Jin Yao)

- Fix some backtrace perf test cases to use 'perf record' + 'perf script'
instead, till 'perf trace' starts using ordered_events or equivalent
to avoid symbol resolving artifacts due to reordering of
PERF_RECORD_MMAP events (Jiri Olsa)

- Fix crash in 'perf record' pipe mode, it needs to allocate the ID
array even for a single event, unlike non-pipe mode (Jiri Olsa)

- Make annoying fallback message on older kernels with newer 'perf top'
binaries trying to use overwrite mode and that not being present
in the older kernels (Kan Liang)

- Switch last users of old APIs to the newer perf_mmap__read_event()
one, then discard those old mmap read forward APIs (Kan Liang)

- Fix the usage on the 'perf kallsyms' man page (Sangwon Hong)

- Simplify cgroup arguments when tracking multiple events (weiping zhang)

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 changes:

- Clean up the x86 instruction decoder (Masami Hiramatsu)

- Add new uprobes optimization for PUSH instructions on x86 (Yonghong
Song)

- Add MSR_IA32_THERM_STATUS to the MSR events (Stephane Eranian)

- Fix misc bugs, update documentation, plus various cleanups (Jiri
Olsa)

There's a large number of tooling side improvements:

- Intel-PT/BTS improvements (Adrian Hunter)

- Numerous 'perf trace' improvements (Arnaldo Carvalho de Melo)

- Introduce an errno code to string facility (Hendrik Brueckner)

- Various build system improvements (Jiri Olsa)

- Add support for CoreSight trace decoding by making the perf tools
use the external openCSD (Mathieu Poirier, Tor Jeremiassen)

- Add ARM Statistical Profiling Extensions (SPE) support (Kim
Phillips)

- libtraceevent updates (Steven Rostedt)

- Intel vendor event JSON updates (Andi Kleen)

- Introduce 'perf report --mmaps' and 'perf report --tasks' to show
info present in 'perf.data' (Jiri Olsa, Arnaldo Carvalho de Melo)

- Add infrastructure to record first and last sample time to the
perf.data file header, so that when processing all samples in a
'perf record' session, such as when doing build-id processing, or
when specifically requesting that that info be recorded, use that
in 'perf report --time', that also got support for percent slices
in addition to absolute ones.

I.e. now it is possible to ask for the samples in the 10%-20% time
slice of a perf.data file (Jin Yao)

- Allow system wide 'perf stat --per-thread', sorting the result (Jin
Yao)
