perf annotate browser: Circulate percent, total-period and nr-samples view (2017-08-18 11:23:20 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
- Support --show-nr-samples in annotate's --stdio and --tui, using
the existing 't' toggle to circulate 'percent', 'total-period' and
'nr-samples' as the first column (Taeung Song)
- Support FCMask and PortMask in JSON vendor events (Andi Kleen)
- Fix off by one string allocation problem in 'perf trace' (Arnaldo Carvalho de Melo)
- Use just one parse events state struct in yyparse(), fixing one
reported segfault when a routine received a different data struct,
smaller than the one it expected to use (Arnaldo Carvalho de Melo)
- Remove unused cpu_relax() macros, they stopped being used when
tools/perf lived in Documentation/ (Arnaldo Carvalho de Melo)
- Fix double file test in libbpf's Makefile (Daniel Díaz):

Test results:
The first ones are container (docker) based builds of tools/perf with and
without libelf support, objtool where it is supported and samples/bpf/, ditto.
Where clang is available, it is also used to build perf with/without libelf.
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.
The 'perf test' also runs shell scripts exercising the tools, checking
if they affect the system in certain ways, like setting up kprobes and
uprobes, request callchains for well known programs and check that they
are the expected ones, see if 'perf trace' beautifies system call
arguments correctly, etc.
Additionally, a new set of tests, script based, runs the tools in a live system,
setting probes in place that then gets used by 'perf trace', with its output
compared against expected results.
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.
