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.

Currently the "opts" variable is not zero-ed and we keep on adding to it, ending up with:

  $ check-headers.sh 2>&1
  + opts=' "-B"'
  + opts=' "-B" "-B"'
  + opts=' "-B" "-B" "-B"'
  + opts=' "-B" "-B" "-B" "-B"'
  + opts=' "-B" "-B" "-B" "-B" "-B"'
  + opts=' "-B" "-B" "-B" "-B" "-B" "-B"'

Fix this by initializing it in the check() function, right before starting the loop.

2.14.3

From: Kan Liang <[email protected]>

There is a segmentation fault when running 'perf trace'. For example:

  [root@jouet e]# perf trace -e *chdir -o /tmp/bla perf report --ignore-vmlinux -i ../perf.data

The perf_mmap__consume() could unmap the mmap. It needs to check the refcnt in perf_mmap__read_done().

From: Arnaldo Carvalho de Melo <[email protected]>

The previous patch is insufficient to cure the reported 'perf trace' segfault, as it only cures the perf_mmap__read_done() case, moving the segfault to perf_mmap__read_init() functio, fix it by doing the same refcount check.
