perf tools: Add Python 3 support (2018-02-19 12:28:23 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
- Initial support for linking with python3, by explicitely setting
the PYTHON Makefile variable, python2 remains supported, more work
needed to test the shipped python scripts used with 'perf script'
(Jaroslav Škarvada)
- Make twatch.py, an example python script that sets up evlists and
evsels to then parse events from mmap, to work with both python2 and
python3 (Arnaldo Carvalho de Melo)
- Fix setting 'perf ftrace' function filter when using a non-existent
function, which should result in an error instead of simply not setting
the filter and showing all functions (Changbin Du)
- Fix paranoid check in machine__set_kernel_mmap(), problem introduced
in previous perf/core batch (Namhyung Kim)
- Fix reading cpuid model information in s/390, ditto, also introduced
in the previous perf/core batch (Thomas Richter)

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}.
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.
