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-v6.1-1-2022-10-07' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

Pull perf tools updates from Arnaldo Carvalho de Melo:

- Add support for AMD on 'perf mem' and 'perf c2c', the kernel
enablement patches went via tip.

Example:

$ sudo perf mem record -- -c 10000
^C[ perf record: Woken up 227 times to write data ]
[ perf record: Captured and wrote 58.760 MB perf.data (836978 samples) ]

$ sudo perf mem report -F mem,sample,snoop
Samples: 836K of event 'ibs_op//', Event count (approx.): 8418762
Memory access Samples Snoop
N/A 700620 N/A
L1 hit 126675 N/A
L2 hit 424 N/A
L3 hit 664 HitM
L3 hit 10 N/A
Local RAM hit 2 N/A
Remote RAM (1 hop) hit 8558 N/A
Remote Cache (1 hop) hit 3 N/A
Remote Cache (1 hop) hit 2 HitM
Remote Cache (2 hops) hit 10 HitM
Remote Cache (2 hops) hit 6 N/A
Uncached hit 4 N/A
$

- "perf lock" improvements:

- Add -E/--entries option to limit the number of entries to
display, say to ask for just the top 5 contended locks.

- Add -q/--quiet option to suppress header and debug messages.

- Add a 'perf test' kernel lock contention entry to test 'perf
lock'.

- "perf lock contention" improvements:

- Ask BPF's bpf_get_stackid() to skip some callchain entries.

The ones closer to the tooling are bpf related and not that
interesting, the ones calling the locking function are the ones
we're interested in, example of a full, unskipped callstack:

- Allow changing the callstack depth and number of entries to skip.

1 10.74 us 10.74 us 10.74 us spinlock __bpf_trace_contention_begin+0xb
0xffffffffc03b5c47 bpf_prog_bf07ae9e2cbd02c5_contention_begin+0x117

0xffffffffbb7eab9b __bpf_trace_contention_begin+0xb
0xffffffffbb7ebe75 queued_spin_lock_slowpath+0x1f5
0xffffffffbc1c26ff _raw_spin_lock+0x1f
0xffffffffbb841015 tick_do_update_jiffies64+0x25
0xffffffffbb8409ee tick_irq_enter+0x9e

- Show full callstack in verbose mode (-v option), sometimes this
is desirable instead of showing just one callstack entry.

- Allow multiple time ranges in 'perf record --delay' to help in
reducing the amount of data collected from hardware tracing (Intel
PT, etc) when there is a rough idea of periods of time where events
of interest take time.

- Add Intel PT to record only decoder debug messages when error
happens.

- Improve layout of Intel PT man page.

- Add new branch types: alignment, data and inst faults and arch
specific ones, such as fiq, debug_halt, debug_exit, debug_inst and
debug_data on arm64.

Kernel enablement went thru the tip tree.

- Fix 'perf probe' error log check in 'perf test' when no debuginfo is
available.

- Fix 'perf stat' aggregation mode logic, it should be looking at the
CPU not at the core number.

- Fix flags parsing in 'perf trace' filters.

- Introduce compact encoding of CPU range encoding on perf.data, to
avoid having a bitmap with all the CPUs.

- Improvements to the 'perf stat' metrics, including adding
"core_wide", and computing "smt" from the CPU topology.

- Add support to the new PERF_FORMAT_LOST perf_event_attr.read_format,
that allows tooling to ask for the precise number of lost samples for
a given event.

- Add 'addr' sort key to see just the address of sampled instructions:

$ perf record -o- true | perf report -i- -s addr
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.000 MB - ]
# Samples: 12 of event 'cycles:u'
# Event count (approx.): 252512
#
# Overhead Address

8.30% 0x7f96f0855028
4.43% 0xffffffff8de01087

perf annotate: Toggle full address <-> offset display

- Add 'f' hotkey to the 'perf annotate' TUI interface when in
'disassembler output' mode ('o' hotkey) to toggle showing full
virtual address or just the offset.

- Cache DSO build-ids when synthesizing PERF_RECORD_MMAP records for
pre-existing threads, at the start of a 'perf record' session,
speeding up that record startup phase.

- Add a command line option to specify build ids in 'perf inject'.

- Update JSON event files for the Intel alderlake, broadwell,
broadwellde, broadwellx, cascadelakex, haswell, haswellx, icelake,
icelakex, ivybridge, ivytown, jaketown, sandybridge, sapphirerapids,
skylake, skylakex, and tigerlake processors.

- Update vendor JSON event files for the ARM Neoverse V1 and E1
platforms.

- Add a 'perf test' entry for 'perf mem' where a struct has false
sharing and this gets detected in the 'perf mem' output, tested with
Intel, AMD and ARM64 systems.

- Add a 'perf test' entry to test the resolution of java symbols, where
an output like this is expected:

0.75% Thread-1 jitted-83602-1670.so [.] jdk.internal.jimage.BasicImageReader.getString(int)

- Add tests for the ARM64 CoreSight hardware tracing feature, with
specially crafted pureloop, memcpy, thread loop and unroll tread that
then gets traced and the output compared with expected output.

Documentation explaining it is also included.

- Add per thread Intel PT 'perf test' entry to check that
PERF_RECORD_TEXT_POKE events are recorded per CPU, resulting in a
mixture of per thread and per CPU events and mmaps, verify that this
gets all recorded correctly.

- Introduce pthread mutex wrappers to allow for building with clang's
-Wthread-safety, i.e. using the "guarded_by" "pt_guarded_by"
"lockable", "exclusive_lock_function", "exclusive_trylock_function",
"exclusive_locks_required", and "no_thread_safety_analysis" compiler
function attributes.

- Fix empty version number when building outside of a git repo.

- Improve feature detection display when multiple versions of a feature
are present, such as for binutils libbfd, that has a mix of possible
ways to detect according to the Linux distribution.

Previously in some cases we had:

Auto-detecting system features
<SNIP>
... libbfd: [ on ]
... libbfd-liberty: [ on ]
... libbfd-liberty-z: [ on ]
<SNIP>

Now for this case we show just the main feature:

Auto-detecting system features
<SNIP>
... libbfd: [ on ]
<SNIP>

- Remove some unused structs, variables, macros, function prototypes
and includes from various places.
