Subject[GIT PULL] perf/core improvements and fixes
Date
Hi,

Please consider pulling, this has v5.3-rc4 merged in to pick up
libbpf fixes,

Best regards,

- Arnaldo

Test results at the end of this message, as usual.

perf ui: No need to set ui_browser to 1 twice (2019-08-14 11:00:00 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

Intel PT:

Adrian Hunter:

- Add PEBS via Intel PT support, the kernel bits went via PeterZ.

perf record:

Alexander Shishkin:

- Add an option to take an AUX snapshot on exit.

Tan Xiaojun:

- Support aarch64 random socket_id assignment, just like was fixed for S/390.

tools:

Andy Shevchenko:

- Keep list of tools in alphabetical order on 'make -C tools help'.

perf session:

Arnaldo Carvalho de Melo:

- Avoid infinite loop when seeing invalid header.size, reported by
Vince Weaver using a perf.data fuzzer.

Documentation:

Vince Weaver:

- Clarify HEADER_SAMPLE_TOPOLOGY format in the perf.data spec.

perf config:

Arnaldo Carvalho de Melo:

- Honour $PERF_CONFIG env var to specify alternate .perfconfig.

perf test:

Arnaldo Carvalho de Melo:

- Disable ~/.perfconfig to get default output in 'perf trace' tests.

perf top:

Arnaldo Carvalho de Melo:

- Set display thread COMM to help with debugging.

- Collapse and resort evsels in a group, so that we have output
similar to 'perf report' when using event groups, i.e.

perf top -e '{cycles,instructions}'

Will have two columns, and the instructions one will work.

core:

Igor Lubashev:

- Detect if libcap development files are available so that we
can use capabilities to match the checks made by the kernel instead
of using plain (geteuid() == 0).

Intel:

Haiyan Song:

- Add Icelake V1.00 event file.

perf trace:

Leo Yan:

- Fix segmentation fault when access syscall info on arm64.

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.

Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.
