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

New features:

- Allow using trace events fields as sort order keys, making 'perf evlist --trace_fields'
show those, and then the user can select a subset and use like:

perf top -e sched:sched_switch -s prev_comm,next_comm

That works as well in 'perf report' when handling files containing
tracepoints.

The default when just tracepoint events are found in a perf.data file is to
format it like ftrace, using the libtraceevent formatters, plugins, etc (Namhyung Kim)

- Add support in 'perf script' to process 'perf stat record' generated files,
culminating in a python perf script that calculates CPI (Cycles per
Instruction) (Jiri Olsa)

- Show random perf tool tips in the 'perf report' bottom line (Namhyung Kim)

- perf report now defaults to --group if the perf.data file has grouped events, try it with:

# perf record -e '{cycles,instructions}' -a sleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 1.093 MB perf.data (1247 samples) ]
# perf report
# Samples: 1K of event 'anon group { cycles, instructions }'
# Event count (approx.): 1955219195

User visible fixes:

- Coect data mmaps so that the DWARF unwinder can handle usecases needing them,
like softice (Jiri Olsa)

- Decay callchains in fractal mode, fixing up cases where 'perf top -g' would
show entries with more than 100% (Namhyung Kim)

Infrastructure changes:

- Sync tools/lib with the lib/ in the kernel sources for find_bit.c and
move bitmap.[ch] from tools/perf/util/ to tools/lib/ (Arnaldo Carvalho de Melo)

- No need to set attr.sample_freq in some 'perf test' entries that only
want to deal with PERF_RECORD_ meta-events, improve a bit error output
for CQM test (Arnaldo Carvalho de Melo)

- Fix python binding build, adding some missing object files now required
due to cpumap using find_bit stuff (Arnaldo Carvalho de Melo)

- tools/build improvemnts (Jiri Olsa)

- Add more files to cscope/ctags databases (Jiri Olsa)

- Do not show 'trace' in 'perf help' if it is not compiled in (Jiri Olsa)

- Make perf_evlist__open() open evsels with their cpus and threads,
like perf record does, making them consistent (Adrian Hunter)

- Fix pmu snapshot initialization bug (Stephane Eranian)

- Add missing headers in perf's MANIFEST (Wang Nan)

Quite a large batch of fixes have come in since the merge window, mainly
driver specific ones but there's a couple of core ones:

- A fix for DAPM resume on active streams to ensure everything ends up
cleanly in the right state.
- Reset the DAPM cache when freeing widgets to fix a crash on driver
remove and reload.

The PM functions for nau8825 are new code which fix crashes on resume.

Use 'perf probe' various options to list functions, see what variables can
be collected at any given point, experiment first collecting without a filter,
then filter, use it together with 'perf trace', 'perf top', with or without
callchains, if it explodes, please tell us!

- Introduce a new callchain mode: "folded", that will list per line
representations of all callchains for a give histogram entry, facilitating
'perf report' output processing by other tools, such as Brendan Gregg's
flamegraph tools (Namhyung Kim)

E.g:

# perf report | grep -v ^# | head
18.37% 0.00% swapper [kernel.kallsyms] [k] cpu_startup_entry
|
---cpu_startup_entry
|
|--12.07%--start_secondary
|
--6.30%--rest_init
start_kernel
x86_64_start_reservations
x86_64_start_kernel
#

Becomes, in "folded" mode:

# perf report -g folded | grep -v ^# | head -5
18.37% 0.00% swapper [kernel.kallsyms] [k] cpu_startup_entry
12.07% cpu_startup_entry;start_secondary
6.30% cpu_startup_entry;rest_init;start_kernel;x86_64_start_reservations;x86_64_start_kernel
16.90% 0.00% swapper [kernel.kallsyms] [k] call_cpuidle
11.23% call_cpuidle;cpu_startup_entry;start_secondary
5.67% call_cpuidle;cpu_startup_entry;rest_init;start_kernel;x86_64_start_reservations;x86_64_start_kernel
16.90% 0.00% swapper [kernel.kallsyms] [k] cpuidle_enter
11.23% cpuidle_enter;call_cpuidle;cpu_startup_entry;start_secondary
5.67% cpuidle_enter;call_cpuidle;cpu_startup_entry;rest_init;start_kernel;x86_64_start_reservations;x86_64_start_kernel
15.12% 0.00% swapper [kernel.kallsyms] [k] cpuidle_enter_state
#

The user can also select one of "count", "period" or "percent" as the first column.

Infrastructure changes:

- Fix multiple leaks found with Valgrind and a refcount
debugger (Masami Hiramatsu)

- Add further 'perf test' entries for BPF and LLVM (Wang Nan)

- Improve 'perf test' to suport subtests, so that the series of tests
performed in the LLVM and BPF main tests appear in the default 'perf test'
output (Wang Nan)

- Move memdup() from tools/perf to tools/lib/string.c (Arnaldo Carvalho de Melo)

- Adopt strtobool() from the kernel into tools/lib/ (Wang Nan)

- Fix selftests_install tools/ Makefile rule (Kevin Hilman)

perf tests: Pass the subtest index to each test routine

Some tests have sub-tests we want to run, so allow passing this.

Wang tried to avoid having to touch all tests, but then, having the
test.func in an anonymous union makes the build fail on older compilers,
like the one in RHEL6, where:

test a = {
.func = foo,
};

fails.

To fix it leave the func pointer in the main structure and pass the subtest
index to all tests, end result function is the same, but we have just one
function pointer, not two, with and without the subtest index as an argument.
