The cycles info is only meaningful when sample has branch stacks. To

annotated_branch' and dynamically allocate it when needed. Also move
cycles_hist from annotated_source as it's related here.

perf annotate: Introduce global annotation_options

[ Upstream commit 9d03194a36345796d4f0f8d6b72eb770a45d614e ]

The annotation options are to control the behavior of objdump and the
output. It's basically used by 'perf annotate' but 'perf report' and
'perf top' can call it on TUI dynamically.

But it doesn't need to have a copy of annotation options in many places.

As most of the work is done in the util/annotate.c file, add a global
variable and set/use it instead of having their own copies.

The cycles info is used only when branch stack is provided. Separate
them from 'struct annotation_line' into a separate struct and lazy
allocate them to save some memory.

Committer notes:

Make annotation__compute_ipc() check if the lazy allocation works,
bailing out if so, its callers already do error checking and
propagation.

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 annotation: Switch lock from a mutex to a sharded_mutex

Remove the "struct mutex lock" variable from annotation that is
allocated per symbol. This removes in the region of 40 bytes per
symbol allocation. Use a sharded mutex where the number of shards is
set to the number of CPUs. Assuming good hashing of the annotation
(done based on the pointer), this means in order to contend there
needs to be more threads than CPUs, which is not currently true in any
perf command. Were contention an issue it is straightforward to
increase the number of shards in the mutex.

On my Debian/glibc based machine, this reduces the size of struct
annotation from 136 bytes to 96 bytes, or nearly 30%.
