> 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.
