perf flamegraph: Use /bin/bash for report and record scripts (2020-05-05 16:35:32 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

perf record:

- Introduce --switch-output-event to use arbitrary events to be setup
and read from a side band thread and, when they take place a signal
be sent to the main 'perf record' thread, reusing the --switch-output
code to take perf.data snapshots from the --overwrite ring buffer, e.g.:

# perf record --overwrite -e sched:* \
--switch-output-event syscalls:*connect* \
workload

will take perf.data.YYYYMMDDHHMMSS snapshots up to around the
connect syscalls.

Stephane Eranian:

- Add --num-synthesize-threads option to control degree of parallelism of the
synthesize_mmap() code which is scanning /proc/PID/task/PID/maps and can be
time consuming. This mimics pre-existing behaviour in 'perf top'.

Intel PT:

Adrian Hunter:

- Add support for synthesizing branch stacks for regular events (cycles,
instructions, etc) from Intel PT data.

perf bench:

Ian Rogers:

- Add a multi-threaded synthesize benchmark.

- Add kallsyms parsing benchmark.

Tommi Rantala:

- Fix div-by-zero if runtime is zero.

perf synthetic events:

- Remove use of sscanf from /proc reading when parsing pre-existing
threads to generate synthetic PERF_RECORD_{FORK,MMAP,COMM,etc} events.

tools api:

- Add a lightweight buffered reading API.

libsymbols:

- Parse kallsyms using new lightweight buffered reading io API.

perf parse-events:

- Fix memory leaks found on parse_events.

perf mem2node:

- Avoid double free related to realloc().

perf stat:

Jin Yao:

- Zero all the 'ena' and 'run' array slot stats for interval mode.

- Improve runtime stat for interval mode

Kajol Jain:

- Enable Hz/hz printing for --metric-only option

- Enhance JSON/metric infrastructure to handle "?".

perf tests:

Kajol Jain:

- Added test for runtime param in metric expression.

Tommi Rantala:

- Fix data path in the session topology test.

perf vendor events power9:

Kajol Jain:

- Add hv_24x7 socket/chip level metric events

Coresight:

Leo Yan:

- Move definition of 'traceid_list' global variable from header file.

Mike Leach:

- Update to build with latest opencsd version.

perf pmu:

Shaokun Zhang:

- Fix function name in comment, its get_cpuid_str(), not get_cpustr()

Stephane Eranian:

- Add perf_pmu__find_by_type() helper

perf script:

Stephane Eranian:

- Remove extraneous newline in perf_sample__fprintf_regs().

Ian Rogers:

- Avoid NULL dereference on symbol.

tools feature:

Stephane Eranian:

- Add support for detecting libpfm4.

perf symbol:

Thomas Richter:

- Fix kernel symbol address display in TUI verbose mode.

perf cgroup:

Tommi Rantala:

- Avoid needless closing of unopened fd

libperf:

He Zhe:

- Add NULL pointer check for cpu_map iteration and NULL
assignment for all_cpus.

Ian Rogers:

- Fix a refcount leak in evlist method.

Arnaldo Carvalho de Melo:

- Rename the code in tools/perf/util, i.e. perf tooling specific, that
operates on 'struct evsel' to evsel__, leaving the perf_evsel__
namespace for the routines in tools/lib/perf/ that operate on
'struct perf_evsel__'.

tools/perf specific libraries:

Konstantin Khlebnikov:

- Fix reading new topology attribute "core_cpus"

- Simplify checking if SMT is active.

perf flamegraph:

Arnaldo Carvalho de Melo:

- Use /bin/bash for report and record scripts, just like all other
such scripts, fixing a package dependency bug in a Linaro
OpenEmbedded build checker.

perf evlist:

Jagadeesh Pagadala:

- Remove duplicate headers.

Miscelaneous:

Zou Wei:

- Remove unneeded semicolon in libtraceevent, 'perf c2c' and others.

- Fix warning assignment of 0/1 to bool variable in 'perf report'

Test results:

The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Ubuntu 19.10 and debian experimental are failing when linking against
libllvm, which isn't the default, needs to be investigated, haven't
tested with CC=gcc, but should be the same problem:
