perf ftrace: Add ftrace.tracer config option (2017-01-31 16:20:09 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
New features:
. Allow configuring a 'perf ftrace' default --tracer (Taeung Song)
Infrastructure:
. Sync tools/arch/{powerpc,arm}/include/uapi/asm/kvm.h and
tools/arch/x86/include/asm/cpufeatures.h (Ingo Molnar)
. Add BPF program file system pinning APIs and respective
'perf test' entry (Joe Stringer)
. Make tools tree support 'make -s' (Josh Poimboeuf)
. Reference count maps in callchains, fixing SEGFAULT when
referencing maps after it is freed (Krister Johansen)
. Create for_each_event trace points iterator (Taeung Song)
. Do not consider an error not to have any perfconfig file
(Arnaldo Carvalho de Melo
. Propagate perf_config() errors (Arnaldo Carvalho de Melo)

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.
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.
