Subject: [GIT PULL 00/11] perf/core improvements and fixes
Hi Ingo,
Please consider pulling,

Test results at the end of this message, as usual.
The following changes since commit 61f63e383784bd0ab6529cfc95ddc59c713afcc9:

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@...hat.com>
----------------------------------------------------------------
Alexander Shishkin (3):
tools lib api fs: Introduce sysfs__read_bool
tools include: Sync {,tools/}include/uapi/linux/perf_event.h
perf tools: Handle partial AUX records and print a warning
Arnaldo Carvalho de Melo (5):
perf lock: Make 'f' part of the common 'lock_options'
perf timechart: Use OPT_PARENT for common options
tools headers: Sync {tools/,}arch/x86/include/asm/cpufeatures.h

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.
