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:

- Improved kbprobes robustness

- Intel PEBS support for PT hardware tracing

- Other Intel PT improvements: high order pages memory footprint
reduction and various related cleanups

- Misc cleanups

The perf tooling side has been very busy in this cycle, with over 300
commits. This is an incomplete high-level summary of the many
improvements done by over 30 developers:

- Lots of updates to the following tools:

'perf c2c'
'perf config'
'perf record'
'perf report'
'perf script'
'perf test'
'perf top'
'perf trace'

- Updates to libperf and libtraceevent, and a consolidation of the
proliferation of x86 instruction decoder libraries.

- Vendor event updates for Intel and PowerPC CPUs,

- Updates to hardware tracing tooling for ARM and Intel CPUs,

- ... and lots of other changes and cleanups - see the shortlog and
Git log for details"

Merge tag 'perf-core-for-mingo-5.4-20190814' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

Pull perf/core improvements and fixes from Arnaldo:

Intel PT:

Adrian Hunter:

- Add PEBS via Intel PT support, the kernel bits went via PeterZ.

perf record:

Alexander Shishkin:

- Add an option to take an AUX snapshot on exit.

Tan Xiaojun:

- Support aarch64 random socket_id assignment, just like was fixed for S/390.

tools:

Andy Shevchenko:

- Keep list of tools in alphabetical order on 'make -C tools help'.

perf session:

Arnaldo Carvalho de Melo:

- Avoid infinite loop when seeing invalid header.size, reported by
Vince Weaver using a perf.data fuzzer.

Documentation:

Vince Weaver:

- Clarify HEADER_SAMPLE_TOPOLOGY format in the perf.data spec.

perf config:

Arnaldo Carvalho de Melo:

- Honour $PERF_CONFIG env var to specify alternate .perfconfig.

perf test:

Arnaldo Carvalho de Melo:

- Disable ~/.perfconfig to get default output in 'perf trace' tests.

perf top:

Arnaldo Carvalho de Melo:

- Set display thread COMM to help with debugging.

- Collapse and resort evsels in a group, so that we have output
similar to 'perf report' when using event groups, i.e.

perf top -e '{cycles,instructions}'

Will have two columns, and the instructions one will work.

core:

Igor Lubashev:

- Detect if libcap development files are available so that we
can use capabilities to match the checks made by the kernel instead
of using plain (geteuid() == 0).

Intel:

Haiyan Song:

- Add Icelake V1.00 event file.

perf trace:

Leo Yan:

- Fix segmentation fault when access syscall info on arm64.

Merge tag 'perf-core-for-mingo-4.20-20181025' 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:

- Introduce 'perf trace --max-events' for stopping 'perf trace' when
that many syscalls (enter+exit), tracepoints or other events such as
page faults take place.

Support that as well on a per-event basis, e.g.:

perf trace -e sched:*switch/nr=2/,block:*_plug/nr=4/,block:*_unplug/nr=1/,net:*dev_queue/nr=3,max-stack=16/

Will stop when 2 context switches, 4 block plugs, 1 block unplug and
3 net_dev_queue tracepoints take place. (Arnaldo Carvalho de Melo)

- Poll for monitored tasks being alive in 'perf stat -p/-t', exiting when
those tasks all terminate (Jiri Olsa)

- Encode -k clockid frequency into perf.data to enable timestamps derived
metrics conversion into wall clock time on reporting stage. (Alexey Budankov)

- Improve Intel PT call graph from SQL database and GUI python scripts,
including adopting the Qt MDI interface to allow for multiple subwindows
for all the tables, helping in better visualizing the data in the SQL
tables, also uses, when available, the Intel XED disassembler libraries
to present the Intel PT data as x86 asm mnemonics. This last feature
is not currently working in some cases, fix is being discussed (Adrian Hunter)

- Implement a ftrace function_graph view in 'perf script' when processing
hardware trace data such as Intel PT (Andi Kleen)

- Better integration with the Intel XED disassembler, when available, in
'perf script' (Andi Kleen)

- Some 'perf trace' drop refcount fixes (Arnaldo Carvalho de Melo)

- Add Sparc support to 'perf annotate', jitdump (David Miller)

- Fix PLT symbols entry/header sizes properly on Sparc (David Miller)

- Fix generation of system call table failure with /tmp mounted with 'noexec'
in arm64 (Hongxu Jia)

- Allow extended console debug output in 'perf script' (Milian Wolff)

- Flush output stream after events in 'perf script' verbose mode (Milian Wolff)

perf script: Make itrace script default to all calls

By default 'perf script' for itrace outputs sampled instructions or
branches. In my experience this is confusing to users because it's hard
to correlate with real program behavior. The sampling makes sense for
tools like 'perf report' that actually sample to reduce the run time,
but run time is normally not a problem for 'perf script'. It's better
to give an accurate representation of the program flow.

Default 'perf script' to output all calls for itrace. That's a much saner
default. The old behavior can be still requested with 'perf script'
