perf tools: Ditch rtrim(), use strim() from tools/lib

2019-07-02T01:50:33+00:00

Cleaning up a bit more tools/perf/util/ by using things we got from the
kernel and have in tools/lib/

tools perf: Move from sane_ctype.h obtained from git to the Linux's original

2019-06-26T00:02:47+00:00

We got the sane_ctype.h headers from git and kept using it so far, but
since that code originally came from the kernel sources to the git
sources, perhaps its better to just use the one in the kernel, so that
we can leverage tools/perf/check_headers.sh to be notified when our copy
gets out of sync, i.e. when fixes or goodies are added to the code we've
copied.

This will help with things like tools/lib/string.c where we want to have
more things in common with the kernel, such as strim(), skip_spaces(),
etc so as to go on removing the things that we have in tools/perf/util/
and instead using the code in the kernel, indirectly and removing things
like EXPORT_SYMBOL(), etc, getting notified when fixes and improvements
are made to the original code.

Hopefully this also should help with reducing the difference of code
hosted in tools/ to the one in the kernel proper.

perf evsel: Fix swap for samples with raw data

2017-12-27T15:15:56+00:00

When we detect a different endianity we swap event before processing.
It's tricky for samples because we have no idea what's inside. We treat
it as an array of u64s, swap them and later on we swap back parts which
are different.

We mangle this way also the tracepoint raw data, which ends up in report
showing wrong data:

  1.95%  comm=Q^B pid=29285 prio=16777216 target_cpu=000
  1.67%  comm=l^B pid=0 prio=16777216 target_cpu=000

Luckily the traceevent library handles the endianity by itself (thank
you Steven!), so we can pass the RAW data directly in the other
endianity.

  2.51%  comm=beah-rhts-task pid=1175 prio=120 target_cpu=002
  2.23%  comm=kworker/0:0 pid=11566 prio=120 target_cpu=000

The fix is basically to swap back the raw data if different endianity is
detected.

perf mmap: Move perf_mmap and methods to separate mmap.[ch] files

To better organize the sources, and we may end up even using it
directly, without evlists and evsels.

perf buildid-cache: Support binary objects from other namespaces

2017-07-19T02:14:11+00:00

Teach buildid-cache how to add, remove, and update binary objects from
other mount namespaces.  Allow probe events tracing binaries in
different namespaces to add their objects to the probe and build-id
caches too.  As a handy side effect, this also lets us access SDT probes
in binaries from alternate mount namespaces.

perf tools: Add missing object file to the python binding linkage list

2016-10-28T13:29:45+00:00

In ac12f6764c50 ("perf tools: Implement branch_type event parameter") we
started using the parse_branch_str() function from one of the files used
in the python binding, which caused this entry in 'perf test' to fail:

  # perf test -v python
  16: Try 'import perf' in python, checking link problems      :
  --- start ---
  test child forked, pid 16667
  Traceback (most recent call last):
    File "", line 1, in 
  ImportError: /tmp/build/perf/python/perf.so: undefined symbol:
  parse_branch_str
  test child finished with -1
  ---- end ----
  Try 'import perf' in python, checking link problems: FAILED!
  #

I must've commited some mistake when running 'perf test' to send the
pull request for the perf-core-for-mingo-20161024 tag, to have let this
regression to pass, sigh.

Just add tools/perf/util/parse-branch-options.c and switch from using
ui__warning(), that is not available in the python binding, use
pr_warning() instead, which is good enough for this case.

Now:

  # perf test python
  16: Try 'import perf' in python, checking link problems      : Ok

tools lib api: Add str_error_c to libapi

2016-07-27T20:16:43+00:00

Because it uses that function, which would lead every tool using it
to need to link against tools/lib/str_error_r.o.

This fixes building tools/vm/, that links with libapi.
