perf tests: Add test for PMU aliases (2021-09-03 08:38:49 -0300)

----------------------------------------------------------------
perf tools changes for v5.15:

New features:

- Improvements for the flamegraph python script, including:

- Display perf.data header
- Display PIDs of user stacks
- Added option to change color scheme
- Default to blue/green color scheme to improve accessibility
- Correctly identify kernel stacks when debuginfo is available

- Improvements for 'perf bench futex':
- Add --mlockall parameter
- Add --broadcast and --pi to the 'requeue' sub benchmark

- Add support for PMU aliases.

- Introduce an ARM Coresight ETE decoder.

- Add a 'perf bench' entry for evlist open/close operations, to help quantify
improvements with multithreading 'perf record'.

- Allow reporting the [un]throttle PERF_RECORD_ meta event in 'perf script's
python scripting.

- Add a 'perf test' entry for PMU aliases.

- Add a 'perf test' entry for 'perf record/perf report/perf script' pipe mode.

Fixes:

- perf script dlfilter (API for filtering via dynamically loaded shared object
introduced in v5.14) fixes and a 'perf test' entry for it.

- Fix get_current_dir_name() compilation on Android.

- Fix issues with asciidoc and double dashes uses.

- Fix memory leaks in the BTF handling code.

- Fix leftover problems in the Documentation from the infrastructure originally
lifted from the git codebase.

- Fix *probe_vfs_getname.sh 'perf test' failures.

- Handle fd gaps in 'perf test's test__dso_data_reopen().

- Make sure to show disasembly warnings for 'perf annotate --stdio'.

- Fix output from pipe to file and vice-versa in 'perf record/report/script'.

- Correct 'perf data -h' output.

- Fix wrong comm in system-wide mode with 'perf record --delay'.

- Do not allow --for-each-cgroup without cpu in 'perf stat'

- Make 'perf test --skip' work on shell tests.

- Fix libperf's verbose printing.

Misc improvements:

- Preparatory patches for multithreading varios 'perf record' phases
(synthesizing, opening, recording, etc).

- Add sparse context/locking annotations in compiler-types.h, also to help with
the multithreading effort.

- Optimize the generation of the arch specific erno tables used in 'perf trace'.

- Optimize libperf's perf_cpu_map__max().

- Improve ARM's CoreSight warnings.

- Report collisions in AUX records.

- Improve warnings for the LLVM 'perf test' entry.

- Improve the PMU events 'perf test' codebase.

- perf test: Do not compare overheads in the zstd comp test

- Better support annotation on ARM.

- Update 'perf trace's cmd string table to decode sys_bpf() first arg.

Vendor events:

- Add JSON events and metrics for Intel's Ice Lake, Tiger Lake and Elhart Lake.

- Update JSON eventsand metrics for Intel's Cascade Lake and Sky Lake servers.

Hardware tracing:

- Improvements for the ARM hardware tracing auxtrace support.

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.

The following ones are now being run on all the containers, so far just with
gcc, clang will come later. All clear for this batch.

There is still the mageia:7 distro + clang 8 failure, seemingly unrelated to
the patches in this series, it'll be investigated. It builds just fine with gcc
8.4.

There is also a strange one with openmandriva:cooker, where on the feature build
test it doesn't manage to find libpthread, looks like a distro problem, will keep
it there to see if a refreshed container cures this soon.
