 tagger Arnaldo Carvalho de Melo <acme@redhat.com> 1608834693 -0300
 
 perf tools changes for v5.11, 2nd batch:
 
 - Refactor 'perf stat' per CPU/socket/die/thread aggregation fixing use
   cases in ARM machines.
 
 - Fix memory leak when synthesizing SDT probes in 'perf probe'.
 
 - Update kernel header copies related to KVM, epol_pwait. msr-index and
   powerpc and s390 syscall tables.

 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.
