perf auxtrace: Add CPU filter support (2017-06-30 11:50:55 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
Intel PT:
- Support "ptwrite" instructio, a way to stuff 32 or 64 bit values into
the Intel PT trace (Adrian Hunter)
- Support power events in Intel PT to report changes to C-state (Adrian
Hunter)
- Synthesize Intel PT events as PERF_RECORD_SAMPLE records with a
perf_event_attr.type (PERF_TYPE_SYNTH) just after the range used by the
kernel, i.e. right after what is allocated for PMUs, at INT_MAX + 1U,
attr.config will have the identification for the synthesized event and
the PERF_SAMPLE_RAW payload will have its fields (Adrian Hunter)
Infrastructure:
- Remove warning() and error(), using instead pr_warning() and
pr_error(), consolidating error reporting (Arnaldo Carvalho de Melo)
- Add platform dependency to 'perf test 15' (Thomas Richter)

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.
