perf tools: Move symbol__calc_percent() call to outside symbol__disassemble() (2017-11-17 12:16:26 -0300)

perf/core improvements and fixes:

- Optimize sample parsing for ordering events, where we don't need to parse
all the PERF_SAMPLE_ bits, just the ones leading to the timestamp needed
to reorder events (Jiri Olsa)

- Use a dummy event to ask for PERF_RECORD_{MMAP,COMM,EXEC} with
'perf record --delay', when the events asked by the user will only be
enabled after the workload is started and the requested delay passes,
so we need to add the dummy event and have it .enabled_on_exec. This
then allows us to resolve symbols for the DSO executable MMAPs setup
while we wait for the delay (Arnaldo Carvalho de Melo)

- Synchronize kcmp.h and prctl.h ABI headers wrt SPDX tags (Arnaldo Carvalho de Melo)

- Generalize the annotation code to support other source information
besides objdump/DWARF obtained ones, starting with python scripts,
that will is slated to be merged soon (Jiri Olsa)

- Advance the source code lines to right after the column with the
address in asm lines (Jiri Olsa)

- Fix terminal dimensions resizing signal handling in 'perf top --stdio' (Jiri Olsa)

- Improve error messages for PMU events (Kim Phillips)

- Fix 'perf record' -c/-F options for cpu event aliases (Andi Kleen)

- Enable type checking for perf_evsel_config_term types (Andi Kleen)

- Call machine__exit() at 'perf trace' exit, so as to remove temporary
files related to VDSO (Andrei Vagin)

- Add "reject" option to parse-events.l, fixing the build with newer
flex releases. Noticed with flex 2.6.4 on Alpine Linux 3.6 and Edge (Jiri Olsa)

- Document some missing headers (Andi Kleen)

- Allow printing period for non freq mod groups (Andi Kleen)

- Do not warn the user about kernel.kptr_restrict when not sampling the
kernel (Arnaldo Carvalho de Melo)

- Fix bug in 'perf help' introduced during conversion to strstart() (Namhyung Kim)

- Do not truncate ASM instruction mnemonics at 6 characters in the annotation
output, PowerPC has long ones (Ravi Bangoria)

- Document some missing command line options (Sihyeon Jang)

- Update POWER9 vendor event tables (Sukadev Bhattiprolu)

- Fix 'perf test' shell entries on s390x, where the 'openat' syscall
is used instead of 'open' in one of the tests and

- No need to use overwrite mmap mode in 'perf test', those tests
do not generate massive amount of events to fill the ring buffer (Wang Nan)

- Add missing command line options (mostly --force/-f) to the man pages (Sihyeon Jang)

Test results:

The first ones are container (docker) based builds of tools/perf with and
without libelf support. Where clang is available, it is also used to build
perf with/without libelf.

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

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.
