perf record: Disable debuginfod by default (2022-01-15 17:41:25 -0300)
----------------------------------------------------------------
perf tools changes for v5.17: 1st batch
New features:
- Add 'trace' subcommand for 'perf ftrace', setting the stage for more
'perf ftrace' subcommands. Not using a subcommand yields the previous
behaviour of 'perf ftrace'.
- Add 'latency' subcommand to 'perf ftrace', that can use the function
graph tracer or a BPF optimized one, via the -b/--use-bpf option.
E.g.:
$ sudo perf ftrace latency -a -T mutex_lock sleep 1

The original implementation of this command was in the bcc tool.
- Support --cputype option for hybrid events in 'perf stat'.
Improvements:
- Call chain improvements for ARM64.
- No need to do any affinity setup when profiling pids.
- Reduce multiplexing with duration_time in 'perf stat' metrics.
- Improve error message for uncore events, stating that some event groups are
can only be used in system wide (-a) mode.
- perf stat metric group leader fixes/improvements, including arch specific
changes to better support Intel topdown events.
- Probe non-deprecated sysfs path 1st, i.e. try /sys/devices/system/cpu/cpuN/topology/thread_siblings
first, then the old /sys/devices/system/cpu/cpuN/topology/core_cpus.
- Disable debuginfod by default in 'perf record', to avoid stalls on distros
such as Fedora 35.
- Use unbuffered output in 'perf bench' when pipe/tee'ing to a file.
- Enable ignore_missing_thread in 'perf trace'
Fixes:
- Avoid TUI crash when navigating in the annotation of recursive functions.
- Fix hex dump character output in 'perf script'.
- Fix JSON indentation to 4 spaces standard in the ARM vendor event files.
- Fix use after free in metric__new().
- Fix IS_ERR_OR_NULL() usage in the perf BPF loader.
- Fix up cross-arch register support, i.e. when printing register names take
into account the architecture where the perf.data file was collected.
- Fix SMT fallback with large core counts.
- Don't lower case MetricExpr when parsing JSON files so as not to lose info
such as the ":G" event modifier in metrics.
perf test:
- Add basic stress test for sigtrap handling to 'perf test'.
- Fix 'perf test' failures on s/390
- Enable system wide for metricgroups test in 'perf test´.
- Use 3 digits for test numbering now we can have more tests.
Arch specific:
- Add events for Arm Neoverse N2 in the ARM JSON vendor event files
- Support PERF_MEM_LVLNUM encodings in powerpc, that came from a single
patch series, where I incorrectly merged the kernel bits, that were then
reverted after coordination with Michael Ellerman and Stephen Rothwell.
- Add ARM SPE total latency as PERF_SAMPLE_WEIGHT.
- Update AMD documentation, with info on raw event encoding.
- Add support for global and local variants of the "p_stage_cyc" sort key,
applicable to perf.data files collected on powerpc.
- Remove duplicate and incorrect aux size checks in the ARM CoreSight ETM code.
Refactorings:
- Add a perf_cpu abstraction to disambiguate CPUs and CPU map indexes, fixing
problems along the way.
- Document CPU map methods.
UAPI sync:
- Update arch/x86/lib/mem{cpy,set}_64.S copies used in 'perf bench mem memcpy'
- Sync UAPI files with the kernel sources: drm, msr-index, cpufeatures.
Build system
- Enable warnings through HOSTCFLAGS.
- Drop requirement for libstdc++.so for libopencsd check
libperf:
- Make libperf adopt perf_counts_values__scale() from tools/perf/util/.
- Add a stat multiplexing test to libperf.

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.
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.
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. This has been the case
for quite a while, probably time to drop building for those distros?
Ubuntu 20.04 is failing on a corner case where perf links with libllvm and libclang,
which isn't the default perf build.
