Subject: [GIT PULL 00/21] perf/core improvements and fixes
Hi Ingo,
Please consider pullimg,

tools arch: Update arch/x86/lib/memcpy_64.S copy used in 'perf bench mem memcpy' (2018-08-20 10:17:14 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
LLVM/clang/eBPF: (Arnaldo Carvalho de Melo)
- Allow passing options to llc in addition to to clang.
Hardware tracing: (Jack Henschel)
- Improve error message for PMU address filters, clarifying availability of
that feature in hardware having hardware tracing such as Intel PT.
Python interface: (Jiri Olsa)
- Fix read_on_cpu() interface.
ELF/DWARF libraries: (Jiri Olsa)
- Fix handling of the combo compressed module file + decompressed associated
debuginfo file.
Build (Rasmus Villemoes)
- Disable parallelism for 'make clean', avoiding multiple submakes deleting
the same files and causing the build to fail on systems such as Yocto.
Kernel ABI copies: (Arnaldo Carvalho de Melo)
- Update tools's copy of x86's cpufeatures.h.
- Update arch/x86/lib/memcpy_64.S copy used in 'perf bench mem memcpy'.
Miscellaneous: (Steven Rostedt)
- Change libtraceevent to SPDX License format.

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.
