perf machine: Ditch find_kernel_function variants (2018-04-30 12:20:54 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
perf stat: (Jiri Olsa)
- Display time in precision based on std deviation
- Add --table option to display time of each run
- Display length strings of each run for --table option
perf buildid-cache: (Ravi Bangoria)
- Add --list and --purge-all options
perf test: (Hendrik Brueckner)
- Let 'perf test list' display subtests
Core libraries:
- Remove the splitting of maps into MAP__FUNCTION and MAP__VARIABLE.
It isn't needed, adds complexity, so remove this split in a very granular
fashion using better ways of detecting if a map is executable, using map->prot,
etc. More is needed to further untangle map aspects from DSO ones and
also to have arch specific stuff better isolated. (Arnaldo Carvalho de Melo)
- Fix spelling mistake: "builid" -> "buildid" in a jitdump error
message (Colin Ian King)
Build system: (Jiri Olsa)
- Add support to check 2 independent files in check-headers.sh
Documentation: (Takashi Iwai)
- Support for asciidoctor, since 'asciidoc' wasn't so far ported to
python3 and distros are ditching python2

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, 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.
