Hi Ingo,

Please consider pulling, mostly fixes, some late coming
improvements in non-core areas,

- Arnaldo

Test results at the end of this message, as usual.

perf tools: Do not zero sample_id_all for group members (2018-11-06 08:29:56 -0300)

----------------------------------------------------------------
perf/urgent improvements and fixes:

Intel PT sql viewer: (Adrian Hunter)

- Fall back to /usr/local/lib/libxed.so
- Add Selected branches report
- Add help window
- Fix table find when table re-ordered

Intel PT debug log (Adrian Hunter)

- Add more event information
- Add MTC and CYC timestamps

perf record: (Andi Kleen)

- Support weak groups, just like with 'perf stat'

perf trace: (Arnaldo Carvalho de Melo)

- Start augmenting raw_syscalls:{sys_enter,sys_exit}: goal is to have a
generic, arch independent eBPF kernel component that is programmed with
syscall table details, what to copy, how many bytes, pid, arg filters from the
userspace via eBPF maps by the 'perf trace' tool that continues to use all its
argument beautifiers, just taking advantage of the extra pointer contents.

JVMTI: (Gustavo Romero)

- Fix undefined symbol scnprintf in libperf-jvmti.so

perf top: (Jin Yao)

- Display the LBR stats in callchain entries

perf stat: (Thomas Richter)

- Handle different PMU names with common prefix

arm64: Will (Deacon)

- Fix arm64 tools build failure wrt smp_load_{acquire,release}.

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, 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.
