MAINTAINERS: Add Namhyung as tools/perf/ co-maintainer (2024-01-08 17:29:15 -0300)

----------------------------------------------------------------
perf tools improvements and fixes for v6.8:

- Add Namhyung Kim as tools/perf/ co-maintainer, we're taking turns processing
patches, switching roles from perf-tools to perf-tools-next at each Linux
release.

Data profiling:

- Associate samples that identify loads and stores with data structures. This
uses events available on Intel, AMD and others and DWARF info:

# To get memory access samples in kernel for 1 second (on Intel)
$ perf mem record -a -K --ldlat=4 -- sleep 1

# Similar for the AMD (but it requires 6.3+ kernel for BPF filters)
$ perf mem record -a --filter 'mem_op == load || mem_op == store, ip > 0x8000000000000000' -- sleep 1

Then, amongst several modes of post processing, one can do things like:

$ perf report -s type,typeoff --hierarchy --group --stdio
...
#
# Samples: 10K of events 'cpu/mem-loads,ldlat=4/P, cpu/mem-stores/P, dummy:u'

This uses the existing annotate code, calling objdump to do the disassembly,
with improvements to avoid having this take too long, but longer term a
switch to a disassembler library, possibly reusing code in the kernel will
be pursued.

This is the initial implementation, please use it and report impressions and
bugs. Make sure the kernel-debuginfo packages match the running kernel. The
'perf report' phase for non short perf.data files may take a while.

There is a great article about it on LWN:

One last test I did while writing this text, on a AMD Ryzen 5950X, using a distro
kernel, while doing a simple 'find /' on an otherwise idle system resulted in:

perf top/report:

- Don't ignore job control, allowing control+Z + bg to work.

- Add s390 raw data interpretation for PAI (Processor Activity Instrumentation)
counters.

perf archive:

- Add new option '--all' to pack perf.data with DSOs.

- Add new option '--unpack' to expand tarballs.

Initialization speedups:

- Lazily initialize zstd streams to save memory when not using it.

- Lazily allocate/size mmap event copy.

- Lazy load kernel symbols in 'perf record'.

- Be lazier in allocating lost samples buffer in 'perf record'.

- Don't synthesize BPF events when disabled via the command line (perf record --no-bpf-event).

Assorted improvements:

- Show note on AMD systems that the :p, :pp, :ppp and :P are all the same, as
IBS (Instruction Based Sampling) is used and it is inherentely precise, not
having levels of precision like in Intel systems.

- When 'cycles' isn't available, fall back to the "task-clock" event when not
system wide, not to 'cpu-clock'.

- Add --debug-file option to redirect debug output, e.g.:

$ perf --debug-file /tmp/perf.log record -v true

- Shrink 'struct map' to under one cacheline by avoiding function pointers for
selecting if addresses are identity or DSO relative, and using just a byte for
some boolean struct members.

- Resolve the arch specific strerrno just once to use in perf_env__arch_strerrno().

- Reduce memory for recording PERF_RECORD_LOST_SAMPLES event.

Assorted fixes:

- Fix the default 'perf top' usage on Intel hybrid systems, now it starts with
a browser showing the number of samples for Efficiency (cpu_atom/cycles/P) and
Performance (cpu_core/cycles/P). This behaviour is similar on ARM64, with its
respective set of big.LITTLE processors.

- Fix segfault on build_mem_topology() error path.

- Fix 'perf mem' error on hybrid related to availability of mem event in a PMU.

- Fix missing reference count gets (map, maps) in the db-export code.

- Avoid recursively taking env->bpf_progs.lock in the 'perf_env' code.

- Use the newly introduced maps__for_each_map() to add missing locking around
iteration of 'struct map' entries.

- Parse NOTE segments until the build id is found, don't stop on the first one,
ELF files may have several such NOTE segments.

- Remove 'egrep' usage, its deprecated, use 'grep -E' instead.

- Warn first about missing libelf, not libbpf, that depends on libelf.

- Use alternative to 'find ... -printf' as this isn't supported in busybox.

- Address python 3.6 DeprecationWarning for string scapes.

- Fix memory leak in uniq() in libsubcmd.

- Fix man page formatting for 'perf lock'

- Fix some spelling mistakes.

perf tests:

- Fail shell tests that needs some symbol in perf itself if it is stripped.
These tests check if a symbol is resolved, if some hot function is indeed
detected by profiling, etc.

- The 'perf test sigtrap' test is currently failing on PREEMPT_RT, skip it if
sleeping spinlocks are detected (using BTF) and point to the mailing list
discussion about it. This test is also being skipped on several architectures
(powerpc, s390x, arm and aarch64) due to other pending issues with intruction
breakpoints.

- Adjust test case perf record offcpu profiling tests for s390.

- Fix 'Setup struct perf_event_attr' fails on s390 on z/VM guest, addressing
issues caused by the fallback from cycles to task-clock done in this release.

- Fix mask for VG register in the user-regs test.

- Use shellcheck on 'perf test' shell scripts automatically to make sure changes
don't introduce things it flags as problematic.

- Add option to change objdump binary and allow it to be set via 'perf config'.

- Add basic 'perf script', 'perf list --json" and 'perf diff' tests.

- Basic branch counter support.

- Make DSO tests a suite rather than individual.

- Remove atomics from test_loop to avoid test failures.

- Fix call chain match on powerpc for the record+probe_libc_inet_pton test.

- Improve Intel hybrid tests.

Vendor event files (JSON):

powerpc:

- Update datasource event name to fix duplicate events on IBM's Power10.

- Add PVN for HX-C2000 CPU with Power8 Architecture.

Intel:

- Alderlake/rocketlake metric fixes.

- Update emeraldrapids events to v1.02.

- Update icelakex events to v1.23.

- Update sapphirerapids events to v1.17.

- Add skx, clx, icx and spr upi bandwidth metric.

AMD:

- Add Zen 4 memory controller events.

RISC-V:

- Add StarFive Dubhe-80 and Dubhe-90 JSON files.
https://www.starfivetech.com/en/site/cpu-u

- Add T-HEAD C9xx JSON file.
https://github.com/riscv-software-src/opensbi/blob/master/docs/platform/thead-c9xx.md

ARM64:

- Remove UTF-8 characters from cmn.json, that were causing build failure in some
distros.

- Add core PMU events and metrics for Ampere One X.

- Rename Ampere One's BPU_FLUSH_MEM_FAULT to GPC_FLUSH_MEM_FAULT

libperf:

- Rename several perf_cpu_map constructor names to clarify what they really do.

- Ditto for some other methods, coping with some issues in their semantics,
like perf_cpu_map__empty() -> perf_cpu_map__has_any_cpu_or_is_empty().

- Document perf_cpu_map__nr()'s behavior

perf stat:

- Exit if parse groups fails.

- Combine the -A/--no-aggr and --no-merge options.

- Fix help message for --metric-no-threshold option.

Hardware tracing:

ARM64 CoreSight:

- Bump minimum OpenCSD version to ensure a bugfix is present.

- Add 'T' itrace option for timestamp trace

- Set start vm addr of exectable file to 0 and don't ignore first sample on the
arm-cs-trace-disasm.py 'perf script'.

perf test record user-regs: Fix mask for vg register
perf archive: Add new option '--all' to pack perf.data with DSOs
perf archive: Add new option '--unpack' to expand tarballs

Yang Jihong (2):
perf tools: Add the python_ext_build directory to .gitignore
perf tools: Add --debug-file option to redirect debug output

Yicong Yang (2):
perf header: Fix one memory leakage in perf_event__fprintf_event_update()
perf hisi-ptt: Fix one memory leakage in hisi_ptt_process_auxtrace_event()

zhaimingbing (3):
perf tests attr: Fix spelling mistake "whic" to "which"
perf script perl: Fail check on dynamic allocation
perf lock: Fix a memory leak on an error path

zhujun2 (1):
perf tests coresight: Remove unused variables
