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"

perf LoongArch: Simplify mksyscalltbl

In order to print the numerical entries of the syscall table,
there is no need to call the host compiler to build and then
run a program, this can be done directly by the shell script.

This is similar with commit 9854e7ad35fe ("perf arm64: Simplify
mksyscalltbl"). For now, the mksyscalltbl file of LoongArch is
almost same with arm64.
