perf record: Move setting tracking events before record__init_thread_masks()

[ Upstream commit 1285ab300d598ead593b190af65a16f4b0843c68 ]

User space tasks can migrate between CPUs, so when tracing selected CPUs,
sideband for all CPUs is needed. In this case set the cpu map of the evsel
to all online CPUs. This may modify the original cpu map of the evlist.

Therefore, need to check whether the preceding scenario exists before
record__init_thread_masks().

Dummy tracking has been set in record__open(), move it before
record__init_thread_masks() and add a helper for unified processing.

The sys_perf_event_open invoked is as follows:

'perf test' needs to update base-record & system-wide-dummy attr expected values
for test-record-C0:

1. Because a dummy sideband event is added to the sampling of specified
CPUs. When evlist contains evsel of different sample_type,
evlist__config() will change the default PERF_SAMPLE_ID bit to
PERF_SAMPLE_IDENTIFICATION bit.
The attr sample_type expected value of base-record and system-wide-dummy
in test-record-C0 needs to be updated.

2. The perf record uses evlist__add_aux_dummy() instead of
evlist__add_dummy() to add a dummy event.
The expected value of system-wide-dummy attr needs to be updated.

The 'perf test' result is as follows:

# ./perf test list 2>&1 | grep 'Setup struct perf_event_attr'
17: Setup struct perf_event_attr
# ./perf test 17
17: Setup struct perf_event_attr : Ok

Merge tag 'perf-tools-for-v6.4-3-2023-05-06' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

Pull perf tool updates from Arnaldo Carvalho de Melo:
"Third version of perf tool updates, with the build problems with with
using a 'vmlinux.h' generated from the main build fixed, and the bpf
skeleton build disabled by default.

Build:

- Require libtraceevent to build, one can disable it using
NO_LIBTRACEEVENT=1.

It is required for tools like 'perf sched', 'perf kvm', 'perf
trace', etc.

libtraceevent is available in most distros so installing
'libtraceevent-devel' should be a one-time event to continue
building perf as usual.

Using NO_LIBTRACEEVENT=1 produces tooling that is functional and
sufficient for lots of users not interested in those libtraceevent
dependent features.

- Allow Python support in 'perf script' when libtraceevent isn't
linked, as not all features requires it, for instance Intel PT does
not use tracepoints.

- Error if the python interpreter needed for jevents to work isn't
available and NO_JEVENTS=1 isn't set, preventing a build without
support for JSON vendor events, which is a rare but possible
condition. The two check error messages:

$(error ERROR: No python interpreter needed for jevents generation. Install python or build with NO_JEVENTS=1.)
$(error ERROR: Python interpreter needed for jevents generation too old (older than 3.6). Install a newer python or build with NO_JEVENTS=1.)

- Make libbpf 1.0 the minimum required when building with out of
tree, distro provided libbpf.

- Use libsdtc++'s and LLVM's libcxx's __cxa_demangle, a portable C++
demangler, add 'perf test' entry for it.

- Make binutils libraries opt in, as distros disable building with it
due to licensing, they were used for C++ demangling, for instance.

- Switch libpfm4 to opt-out rather than opt-in, if libpfm-devel (or
equivalent) isn't installed, we'll just have a build warning:

Makefile.config:1144: libpfm4 not found, disables libpfm4 support. Please install libpfm4-dev

- Add a feature test for scandirat(), that is not implemented so far
in musl and uclibc, disabling features that need it, such as
scanning for tracepoints in /sys/kernel/tracing/events.

perf BPF filters:

- New feature where BPF can be used to filter samples, for instance:

$ sudo ./perf record -e cycles --filter 'period > 1000' true
$ sudo ./perf script
perf-exec 2273949 546850.708501: 5029 cycles: ffffffff826f9e25 finish_wait+0x5 ([kernel.kallsyms])

- In addition to 'period' (PERF_SAMPLE_PERIOD), the other
PERF_SAMPLE_ can be used for filtering, and also some other sample
accessible values, from tools/perf/Documentation/perf-record.txt:

Essentially the BPF filter expression is:

<term> <operator> <value> (("," | "||") <term> <operator> <value>)*

The <term> can be one of:
ip, id, tid, pid, cpu, time, addr, period, txn, weight, phys_addr,
code_pgsz, data_pgsz, weight1, weight2, weight3, ins_lat, retire_lat,
p_stage_cyc, mem_op, mem_lvl, mem_snoop, mem_remote, mem_lock,
mem_dtlb, mem_blk, mem_hops

The <operator> can be one of:
==, !=, >, >=, <, <=, &

The <value> can be one of:
<number> (for any term)
na, load, store, pfetch, exec (for mem_op)
l1, l2, l3, l4, cxl, io, any_cache, lfb, ram, pmem (for mem_lvl)
na, none, hit, miss, hitm, fwd, peer (for mem_snoop)
remote (for mem_remote)
na, locked (for mem_locked)
na, l1_hit, l1_miss, l2_hit, l2_miss, any_hit, any_miss, walk, fault (for mem_dtlb)
na, by_data, by_addr (for mem_blk)
hops0, hops1, hops2, hops3 (for mem_hops)

perf lock contention:

- Show lock type with address.

- Track and show mmap_lock, siglock and per-cpu rq_lock with address.
This is done for mmap_lock by following the current->mm pointer:

$ sudo ./perf lock con -abl -- sleep 10

- Update default map size to 16384.

- Allocate single letter option -M for --map-nr-entries, as it is
proving being frequently used.

- Fix struct rq lock access for older kernels with BPF's CO-RE
(Compile once, run everywhere).

- Fix problems found with MSAn.

perf report/top:

- Add inline information when using --call-graph=fp or lbr, as was
already done to the --call-graph=dwarf callchain mode.

- Improve the 'srcfile' sort key performance by really using an
optimization introduced in 6.2 for the 'srcline' sort key that
avoids calling addr2line for comparision with each sample.

perf sched:

- Make 'perf sched latency/map/replay' to use "sched:sched_waking"
instead of "sched:sched_waking", consistent with 'perf record'
since d566a9c2d482 ("perf sched: Prefer sched_waking event when it
exists").

perf ftrace:

- Make system wide the default target for latency subcommand, run the
following command then generate some network traffic and press
control+C:

# perf ftrace latency -T __kfree_skb
^C

#

perf top:

- Add --branch-history (LBR: Last Branch Record) option, just like
already available for 'perf record'.

- Fix segfault in thread__comm_len() where thread->comm was being
used outside thread->comm_lock.

perf annotate:

- Allow configuring objdump and addr2line in ~/.perfconfig., so that
you can use alternative binaries, such as llvm's.

perf kvm:

- Add TUI mode for 'perf kvm stat report'.

Reference counting:

- Add reference count checking infrastructure to check for use after
free, done to the 'cpumap', 'namespaces', 'maps' and 'map' structs,
more to come.

To build with it use -DREFCNT_CHECKING=1 in the make command line
to build tools/perf. Documented at:

https://perf.wiki.kernel.org/index.php/Reference_Count_Checking

- The above caught, for instance, fix, present in this series:

- Fix maps use after put in 'perf test "Share thread maps"':

'maps' is copied from leader, but the leader is put on line 79
and then 'maps' is used to read the reference count below - so
a use after put, with the put of maps happening within
thread__put.

Fixed by reversing the order of puts so that the leader is put
last.

- Also several fixes were made to places where reference counts were
not being held.

- Make this one of the tests in 'make -C tools/perf build-test' to
regularly build test it and to make sure no direct access to the
reference counted structs are made, doing that via accessors to
check the validity of the struct pointer.

ARM64:

- Fix 'perf report' segfault when filtering coresight traces by
sparse lists of CPUs.

- Add support for 'simd' as a sort field for 'perf report', to show
ARM's NEON SIMD's predicate flags: "partial" and "empty".

arm64 vendor events:

- Add N1 metrics.

Intel vendor events:

- Add graniterapids, grandridge and sierraforrest events.

- Refresh events for: alderlake, aldernaken, broadwell, broadwellde,
broadwellx, cascadelakx, haswell, haswellx, icelake, icelakex,
jaketown, meteorlake, knightslanding, sandybridge, sapphirerapids,
silvermont, skylake, tigerlake and westmereep-dp

- Refresh metrics for alderlake-n, broadwell, broadwellde,
broadwellx, haswell, haswellx, icelakex, ivybridge, ivytown and
skylakex.

perf stat:

- Implement --topdown using JSON metrics.

- Add TopdownL1 JSON metric as a default if present, but disable it
for now for some Intel hybrid architectures, a series of patches
addressing this is being reviewed and will be submitted for v6.5.

- Use metrics for --smi-cost.

- Update topdown documentation.

Vendor events (JSON) infrastructure:

- Add support for computing and printing metric threshold values. For
instance, here is one found in thesapphirerapids json file:

{
"BriefDescription": "Percentage of cycles spent in System Management Interrupts.",
"MetricExpr": "((msr@aperf@ - cycles) / msr@aperf@ if msr@smi@ > 0 else 0)",
"MetricGroup": "smi",
"MetricName": "smi_cycles",
"MetricThreshold": "smi_cycles > 0.1",
"ScaleUnit": "100%"
},

- Test parsing metric thresholds with the fake PMU in 'perf test
pmu-events'.

- Support for printing metric thresholds in 'perf list'.

- Add --metric-no-threshold option to 'perf stat'.

- Add rand (reverse and) and has_pmem (optane memory) support to
metrics.

- Sort list of input files to avoid depending on the order from
readdir() helping in obtaining reproducible builds.

S/390:

- Add common metrics: - CPI (cycles per instruction), prbstate (ratio
of instructions executed in problem state compared to total number
of instructions), l1mp (Level one instruction and data cache misses
per 100 instructions).

- Add cache metrics for z13, z14, z15 and z16.

- Add metric for TLB and cache.

ARM:

- Add raw decoding for SPE (Statistical Profiling Extension) v1.3 MTE
(Memory Tagging Extension) and MOPS (Memory Operations) load/store.

Intel PT hardware tracing:

- Add event type names UINTR (User interrupt delivered) and UIRET
(Exiting from user interrupt routine), documented in table 32-50
"CFE Packet Type and Vector Fields Details" in the Intel Processor
Trace chapter of The Intel SDM Volume 3 version 078.

- Add support for new branch instructions ERETS and ERETU.

- Fix CYC timestamps after standalone CBR
