perf tools: Add tools/include/uapi/asm-generic/fcntl.h to the MANIFEST (2017-07-25 22:46:37 -0300)
----------------------------------------------------------------
perf/core improvemends and fixes for v4.14:
New features:
- Filter out 'sshd' in the tracer ancestry in 'perf trace' syswide tracing,
to elliminate tracing loops (Arnaldo Carvalho de Melo)
- Support lookup of symbols in other mount namespaces in 'perf top' (Krister Johansen)
- Initial 'clone' syscall args beautifier in 'perf trace' (Arnaldo Carvalho de Melo)
User visible:
- Ignore 'fd' and 'offset' args for MAP_ANONYMOUS in 'perf trace'
(Arnaldo Carvalho de Melo)
- Process tracing data in 'perf annotate' pipe mode (David Carrillo-Cisneros)
- Make 'perf report --branch-history' work without callgraphs(-g) option
in perf record (Jin Yao)
- Tag branch type/flag on "to" and tag cycles on "from" in 'perf report' (Jin Yao)
Fixes:
- Fix jvmti linker error when libelf config is disabled (Sudeep Holla)
- Fix cgroups refcount usage (Arnaldo Carvalho de Melo)
- Fix kernel symbol adjustment for s390x (Thomas Richter)
- Fix 'perf report --stdio --show-total-period', it was showing the
number of samples, not the total period (Taeung Song)
Infrastructure:
- Add perf_sample dictionary to tracepoint handlers in 'perf script'
python, which were already present for other types of events
(hardware, etc) (Arun Kalyanasundaram)
- Make build fail on vendor events JSON parse error (Andi Kleen)
- Adopt strstarts() from the kernel (Arnaldo Carvalho de Melo)
Arch specific:
- Set no_aux_samples for the tracking event in Intel PT (Kan Liang)
- Always set no branch for Intel PT dummy event (Kan Liang)
Trivial:
- Simplify some error handlers in 'perf script' (Dan Carpenter)
- Add EXCLUDE_EXTLIBS and EXTRA_PERFLIBS to makefile (David Carrillo-Cisneros)

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.
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.
