Merge tag 'perf-tools-for-v6.5-1-2023-06-28' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools-next

Pull perf tools updates from Namhyung Kim:
"Internal cleanup:

- Refactor PMU data management to handle hybrid systems in a generic
way.

Do more work in the lexer so that legacy event types parse more
easily. A side-effect of this is that if a PMU is specified,
scanning sysfs is avoided improving start-up time.

- Fix hybrid metrics, for example, the TopdownL1 works for both
performance and efficiency cores on Intel machines. To support
this, sort and regroup events after parsing.

- Add reference count checking for the 'thread' data structure.

- Lots of fixes for memory leaks in various places thanks to the ASAN
and Ian's refcount checker.

- Reduce the binary size by replacing static variables with local or
dynamically allocated memory.

- Introduce shared_mutex for annotate data to reduce memory
footprint.

- Make filesystem access library functions more thread safe.

Test:

- Organize cpu_map tests into a single suite.

- Add metric value validation test to check if the values are within
correct value ranges.

- Add perf stat stdio output test to check if event and metric names
match.

- Add perf data converter JSON output test.

- Fix a lot of issues reported by shellcheck(1). This is a
preparation to enable shellcheck by default.

- Make the large x86 new instructions test optional at build time
using EXTRA_TESTS=1.

- Add a test for libpfm4 events.

perf script:

- Add 'dsoff' outpuf field to display offset from the DSO.

$ perf script -F comm,pid,event,ip,dsoff
ls 2695501 cycles: 152cc73ef4b5 (/usr/lib/x86_64-linux-gnu/ld-2.31.so+0x1c4b5)

ls 2695501 cycles: ffffffff992a6db0 ([kernel.kallsyms])

- Adjust width for large PID/TID values.

perf report:

- Robustify reading addr2line output for srcline by checking sentinel
output before the actual data and by using timeout of 1 second.

- Allow config terms (like 'name=ABC') with breakpoint events.

$ perf record -e mem:0x55feb98dd169:x/name=breakpoint/ -p 19646 -- sleep 1

perf annotate:

- Handle x86 instruction suffix like 'l' in 'movl' generally.

- Parse instruction operands properly even with a whitespace. This is
needed for llvm-objdump output.

- Support RISC-V binutils lookup using the triplet prefixes.

- Add '<' and '>' key to navigate to prev/next symbols in TUI.

- Fix instruction association and parsing for LoongArch.

perf stat:

- Add --per-cache aggregation option, optionally specify a cache
level like `--per-cache=L2`.

$ sudo perf stat --per-cache -a -e ls_dmnd_fills_from_sys.ext_cache_remote --\
taskset -c 0-15,64-79,128-143,192-207\

- Allow --cputype option to have any PMU name (not just hybrid).

- Fix output value not to added when it runs multiple times with -r
option.

perf list:

- Show metricgroup description from JSON file called
metricgroups.json.

- Allow 'pfm' argument to list only libpfm4 events and check each
event is supported before showing it.

JSON vendor events:

- Avoid event grouping using "NO_GROUP_EVENTS" constraints. The
topdown events are correctly grouped even if no group exists.

- Add "Default" metric group to print it in the default output. And
use "DefaultMetricgroupName" to indicate the real metric group
name.

- Add AmpereOne core PMU events.

Misc:

- Define man page date correctly.

- Track exception level properly on ARM CoreSight ETM.

- Allow anonymous struct, union or enum when retrieving type names
from DWARF.

- Fix incorrect filename when calling `perf inject --jit`.

- Handle PLT size correctly on LoongArch"

Merge tag 'perf-tools-for-v6.2-1-2022-12-16' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

Pull perf tools updates from Arnaldo Carvalho de Melo:
"Libraries:

- Drop the old copy of libtraceevent in tools/lib/traceevent/ now
that all major distros ship it from its external repository.

This is now just another feature detection, emitting a warning when
the libtraceevent-dev[el] package isn't installed, disabling the
build of perf features and tools that strictly require parsing
things from tracefs while keeping the core functionality present
and working with a subset of the events, the most used ones like
CPU cycles, hardware cache and also vendor events, etc.

This was tested with lots of containers for Fedora, Debian,
OpenSUSE, Alpine Linux, Ubuntu, with cross builds, etc.

Build:

- Update to C standard to gnu11, like was done for the kernel.

- Install the tools/lib/ libraries locally instead of having headers
searched directly from the source code directories, to help the
cases where we can build either from in-kernel source libraries or
from the same library shipped as a distro package, as is the case
with libbpf and was the case with libtraceevent.

perf stat:

- Do not delay the workload with --delay, the delay is just for
starting to count the events, to skip noise at workload startup.

- When we have events for each cgroup, the metric should be printed
for each cgroup separately.

$ perf stat -a --for-each-cgroup system.slice,user.slice --metric-only sleep 1

Performance counter stats for 'system wide':

GHz insn per cycle branch-misses of all branches
system.slice 3.792 0.61 3.24%
user.slice 3.661 2.32 0.37%

- Fix printing field separator in CSV metrics output.

- Fix --metric-only --json output.

- Fix summary output in CSV with --metric-only.

- Update event group check for support of uncore event.

perf test:

- Stop requiring a C toolchain in shell tests, instead add a workload
option that has all the previously C snippets built as part of
'perf test -w' that then get used in the 'perf test' shell scripts.

- Add event group test for events in multiple PMUs

- The "kernel lock contention analysis" test should not print
warnings in quiet mode.

- Add attr tests for ARM64's new VG register.

- Fix record test on KVM guests, as using precise flag with the
br_inst_retired.near_call event causes the test fail on KVM guests,
even when the guests have PMU forwarding enabled and the event
itself is supported, so just remove the precise flag from the
event.

- Add mechanism for skipping attr tests on specific kernel versions
where it is known that these checks will fail.

- Skip watchpoint tests if no watchpoints available.

- Add more Intel PT 'perf test' entries: hybrid CPUs, split the
packet decoder into a suite of subtests.

perf script:

- Introduce task analyzer python script, where one first records some events:

Recording can be done in two ways:

$ perf script record tasks-analyzer -- sleep 10
$ perf record -e sched:sched_switch -a -- sleep 10

The script can parse any perf.data files, as long as it has
sched:sched_switch events, other events will be ignored.

The most simple report use case is to just call the script without
arguments.

Runtime is the time the task was running on the CPU, Time Out-In is
the time between the process being scheduled *out* and scheduled
back *in*. So the last time span between two executions:

$ perf script report tasks-analyzer

perf record:

- Add remaining branch filters: "no_cycles", "no_flags" & "hw_index",
to be used with hardware such as Intel's LBR that allows things
like stitching stacks of two samples to overcome the limits of the
number of LBR registers.

Symbol resolution:

- Handle .debug files created with 'objcopy --only-keep-debug', where
program headers are zeroed and thus can't be used for adjustments,
use the info in the runtime_ss (runtime ELF) instead.

perf trace:

- Add BPF based augmenter for the 'perf_event_open's 'struct
perf_event_attr' argument.

- Add BPF based augmenter for the 'clock_gettime's 'struct timespec'
argument.

- In both cases the syscall tracepoint has just the pointer value, we
need to hook a BPF program to collect the pointer contents, and
then, in userspace, pretty print it in 'perf trace'.

perf list:

- Introduce JSON output of events.

- Streamline how the expression specifying what events should be
shown is handled, fixing several corner cases, such as the metric
filter that is specified as a glob but was using strstr().

perf probe:

- Fix to avoid crashing if DW_AT_decl_file is NULL, coping with clang
generating DWARF5 like that.

- Use dwarf_attr_integrate() as generic DWARF attr accessor as it
supersedes dwarf_attr(), supporting abstact origin DIEs.

perf inject:

- Set PERF_RECORD_MISC_BUILD_ID_SIZE in the PERF_RECORD_HEADER_BUILD_ID
so that perf.data readers can get the real build-id size and avoid
trailing zeroes.

perf data:

- Add tracepoint fields when converting a perf.data file to JSON.

arm64:

- Fix mksyscalltbl, don't lose syscalls due to sort -nu.

- Add Arm Neoverse V2 PMU events.

riscv:

- Add riscv sbi firmware std event files.

- Add Sifive U74 vendor events (JSON) file.

- Add some more events and metrics for Alderlake/Alderlake-N.

Documentation:

- Add data documentation for the PMU structs in the C source code.

Miscellaneous:

- Periodic sanitization of headers, adding missing includes, removing
needless ones, creating new ones, etc.

- Use sig_atomic_t for signal handlers to avoid undefined behaviour
in all perf tools.

- Fixes for libbpf 1.0+ compatibility (maps, etc) on 'perf trace' BPF
examples.

- Remove some old perf bpf examples, leave the best ones that
demonstrate how to associate BPF functions to points in the kernel.

- Make quiet mode consistent between tools.

- Use dedicated non-atomic clear/set bit helpers.

- Use "grep -E" instead of "egrep" as recommended by warning emitted
by GNU grep since at least version 3.8.

- Complete list of supported subcommands in the 'perf daemon' help
message.

- Update John Garry's email address for arm64 perf tooling on the
MAINTAINERS file, he moved from Huawei to Oracle"

perf build: Use libtraceevent from the system

Remove the LIBTRACEEVENT_DYNAMIC and LIBTRACEFS_DYNAMIC make command
line variables.

If libtraceevent isn't installed or NO_LIBTRACEEVENT=1 is passed to the
build, don't compile in libtraceevent and libtracefs support.

This also disables CONFIG_TRACE that controls "perf trace".

CONFIG_LIBTRACEEVENT is used to control enablement in Build/Makefiles,
HAVE_LIBTRACEEVENT is used in C code.

Without HAVE_LIBTRACEEVENT tracepoints are disabled and as such the
commands kmem, kwork, lock, sched and timechart are removed. The
majority of commands continue to work including "perf test".

Committer notes:

Fixed up a tools/perf/util/Build reject and added:

#include <traceevent/event-parse.h>

to tools/perf/util/scripting-engines/trace-event-perl.c.

Had to tweak tools/perf/util/setup.py to make sure the python binding
shared object links with libtraceevent if -DHAVE_LIBTRACEEVENT is
present in CFLAGS.

Building with NO_LIBTRACEEVENT=1 uncovered some more build failures:

- Make building of data-convert-bt.c to CONFIG_LIBTRACEEVENT=y

- perf-$(CONFIG_LIBTRACEEVENT) += scripts/

- bpf_kwork.o needs also to be dependent on CONFIG_LIBTRACEEVENT=y

- The python binding needed some fixups and util/trace-event.c can't be
built and linked with the python binding shared object, so remove it
in tools/perf/util/setup.py and exclude it from the list of
dependencies in the python/perf.so Makefile.perf target.

Building without libtraceevent-devel installed uncovered more build
failures:

- The python binding tools/perf/util/python.c was assuming that
traceevent/parse-events.h was always available, which was the case
when we defaulted to using the in-kernel tools/lib/traceevent/ files,
now we need to enclose it under ifdef HAVE_LIBTRACEEVENT, just like
the other parts of it that deal with tracepoints.

- We have to ifdef the rules in the Build files with
CONFIG_LIBTRACEEVENT=y to build builtin-trace.c and
tools/perf/trace/beauty/ as we only ifdef setting CONFIG_TRACE=y when
setting NO_LIBTRACEEVENT=1 in the make command line, not when we don't
detect libtraceevent-devel installed in the system. Simplification here
to avoid these two ways of disabling builtin-trace.c and not having
CONFIG_TRACE=y when libtraceevent-devel isn't installed is the clean
way.

From Athira:

<quote>
tools/perf/arch/powerpc/util/Build
-perf-y += kvm-stat.o
+perf-$(CONFIG_LIBTRACEEVENT) += kvm-stat.o
</quote>

Then, ditto for arm64 and s390, detected by container cross build tests.

- s/390 uses test__checkevent_tracepoint() that is now only available if
HAVE_LIBTRACEEVENT is defined, enclose the callsite with ifder HAVE_LIBTRACEEVENT.

Also from Athira:

<quote>
With this change, I could successfully compile in these environment:
- Without libtraceevent-devel installed
- With libtraceevent-devel installed
- With “make NO_LIBTRACEEVENT=1”
</quote>

Then, finally rename CONFIG_TRACEEVENT to CONFIG_LIBTRACEEVENT for
consistency with other libraries detected in tools/perf/.
