perf utils: Move perf_config using routines from color.c to separate object (2019-01-21 17:38:56 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
BPF:
Song Liu:
- Introduce PERF_RECORD_KSYMBOL to allow tooling to notice the addition
of new kernel symbols and be able to resolve samples in such symbols.
- Introduce PERF_RECORD_BPF_EVENT to notify tooling about the loading
and unloading of BPF programs, making them visible and allowing for
the request of further information to allow for things like annotation.
- Change the userspace perf tools to handle those new events and to
synthesize them for pre-existing loaded BPF programs.
Kernel:
Arnaldo Carvalho de Melo:
- Make perf_event_output() propagate the output() return, allowing
users to check for -ENOSPC in the ring buffer.
perf report:
Thomas Richter:
- Display arch specific diagnostic counter sets, starting with s390
diagnostic counter sets.
perf session:
Jiri Olsa:
- Introduce a reader object to prep for multithreaded processing
of recorded events.
Misc:
Rasmus Villemoes:
- Replace automatic const char[] variables by statics, to avoid
initializing them at runtime, instead having them in .rodata,
reducing code size.
YueHaibing:
- Remove duplicated workqueue.h include from perf_event.h
Brajeswar Ghosh:
- Remove some more duplicated headers.

Test results:
The first ones are container 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.
