perf unwind: Remove unnecessary test (2019-08-16 12:30:14 -0300)

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

report/script/trace/top:

Arnaldo Carvalho de Melo:

- Allow specifying marker events demarcating when to consider the other events,
i.e. one now can state something like:

# perf probe kernel_function
# perf record -e cycles,probe:kernel_function

And then, in 'perf script' or 'perf report' say:

# perf report --switch-on=probe:kernel_function

And then the cycles event samples will be considered only after we
find the first probe:kernel_function event.

There is also --switch-off=event, to make it stop considering events
out of some window, say to avoid some winding down of a workload.

The same can be done with the "live mode" tools: 'perf top' and 'perf trace'.

There are examples in the cset comments showing how to use it with
SDT events in things like 'systemtap', that have those tracepoint-like
events for the start/end of passes, etc.

Another example involves selecting scheduler events + entry/exit of
a syscall, using the syscalls tracepoints, one can then see the
scheduler events that take place while that syscall is being processed.

In the future this should be possible in record/top/trace via eBPF
where the perf tools would hook into the marker events and enable events
put in place but not enabled when the on/off conditions are the desired
ones, reducing the amount of events sampled, but this userspace only
solution should be good enough for many scenarios.

perf vendor events intel:

Haiyan Song:

- Add Tremontx event file v1.02.

unwind:

John Keeping:

- Fix callchain unwinding when tid != pid, that was working only for the
thread group leader.

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.

Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.
