Hi Ingo,

Please consider pulling,

perf vendor events s390: Add JSON files for IBM z14 (2018-03-27 13:13:39 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

- Be consistent when checking if a perf_mmap instance had
its ring buffer unmmaped, fixing segfaults noticed in
'perf trace' (Kan Liang, Arnaldo Carvalho de Melo)

- Avoid adding the same option multiple times to the 'diff'
command in check-headers.sh (Jiri Olsa)

- Add vendor event files (JSON format) to various IBM
s390 models (z10EC, z10BC, z196, zEC12, zBC12, z13
and z14) (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.
