[GIT PULL 00/44] perf/core fixes and improvements

From: Arnaldo Carvalho de Melo
Date: Thu Mar 21 2019 - 14:52:04 EST


Hi Ingo,

Please consider pulling, this is on top of my previous pull
request, that is outstanding, perf-core-for-mingo-5.1-20190311.

Most of the patches plug exit path reference count and memory
leaks, some simple new features and then a late new one that has been
thru 9 versions before being finally merged, the annotation of BPF
programs, using the BTF information to have even the original source
code intermixed with the JITed code.

Best Regards,

- Arnaldo

perf bpf: Show more BPF program info in print_bpf_prog_info() (2019-03-21 11:27:04 -0300)

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

BPF:

Song Liu:

- Add support for annotating BPF programs, using the PERF_RECORD_BPF_EVENT
and PERF_RECORD_KSYMBOL recently added to the kernel and plugging
binutils's libopcodes disassembly of BPF programs with the existing
annotation interfaces in 'perf annotate', 'perf report' and 'perf top'
various output formats (--stdio, --stdio2, --tui).

perf list:

Andi Kleen:

- Filter metrics when using substring search.

perf record:

Andi Kleen:

- Allow to limit number of reported perf.data files

- Clarify help for --switch-output.

perf report:

Andi Kleen

- Indicate JITed code better.

- Show all sort keys in help output.

perf script:

Andi Kleen:

- Support relative time.

perf stat:

Andi Kleen:

- Improve scaling.

General:

Changbin Du:

- Fix some mostly error path memory and reference count leaks found
using gcc's ASan and UBSan.

Vendor events:

Mamatha Inamdar:

- Remove P8 HW events which are not supported.

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.

is already being addressed by Mathieu and Solomon Tan, the problem is not being
introduced by this patchset.
