Hi Ingo,
Please consider pulling,

Test results at the end of this message, as usual.
The following changes since commit 61f63e383784bd0ab6529cfc95ddc59c713afcc9:
Merge tag 'perf-core-for-mingo-4.12-20170316' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core (2017-03-16 17:29:23 +0100)

tools headers: Sync {tools/,}arch/powerpc/include/uapi/asm/kvm.h (2017-03-20 15:02:29 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
Fixes:
- Fix concat_probe_trace_events() in 'perf probe', it should dereference a
pointer, not test its value (Ravi Bangoria)
User visible:
- Handle partial AUX records, checking if 'kvm_intel.ko' is loaded and
if its 'vmm_exclusive' parameter is set to 0, suggesting tweaking
it to reduce gaps (Alexander Shishkin)
Infrastructure:
- Sync the kvm.h, cpufeatures.h and perf_event.h tools/ headers copies
with the kernel (Arnaldo Carvalho de Melo, Alexander Shishkin)
- 'perf lock' subcommands should include common options, using
OPT_PARENT() (Changbin Du)
- Ditto for 'perf timechart' (Arnaldo Carvalho de Melo)
Documentation:
Correct 'perf stat --no-aggr' description (Ravi Bangoria)
Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

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.

Hi Ingo,
There are some 'perf test' and container failures, but those
don't seem to have been introduced by patches in this series and are
being investigated.

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.
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}.

Hi Ingo,
Please consider pulling, more to come as I go thru Adrian's x86
PTI series and the C++ support improvements to 'perf probe', from
Holger,
Best Regards,

perf bpf: Fix NULL return handling in bpf__prepare_load() (2018-05-16 10:01:55 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
- Add '-e intel_pt//u' test to the 'parse-events' 'perf test' entry,
to help avoiding regressions in the events parser such as one
that caused a revert in v4.17-rc (Arnaldo Carvalho de Melo)
- Fix NULL return handling in bpf__prepare_load() (YueHaibing)
- Warn about 'perf buildid-cache --purge-all' failures (Ravi Bangoria)
- Add infrastructure to help in writing eBPF C programs to be used
with '-e name.c' type events in tools such as 'record' and 'trace',
with headers for common constructs and an examples directory that
will get populated as we add more such helpers and the 'perf bpf'
branch that Jiri Olsa has been working on (Arnaldo Carvalho de Melo)
- Handle uncore event aliases in small groups properly (Kan Liang)
- Use the "_stest" symbol to identify the kernel map when loading kcore (Adrian Hunter)
Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
----------------------------------------------------------------
Adrian Hunter (1):
perf tools: Use the "_stest" symbol to identify the kernel map when loading kcore
Arnaldo Carvalho de Melo (7):
perf tests parse-events: Add intel_pt parse test
perf llvm-utils: Add bpf include path to clang command line
perf bpf: Add 'examples' directories
perf bpf: Add bpf.h to be used in eBPF proggies
perf bpf: Add kprobe example to catch 5s naps
perf bpf: Add license(NAME) helper
perf bpf: Add probe() helper to reduce kprobes boilerplate
Kan Liang (1):
perf parse-events: Handle uncore event aliases in small groups properly

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.
