Pull perf tools updates from Arnaldo Carvalho de Melo:
"Add Namhyung Kim as tools/perf/ co-maintainer, we're taking turns
processing patches, switching roles from perf-tools to perf-tools-next
at each Linux release.
Data profiling:
- Associate samples that identify loads and stores with data
structures. This uses events available on Intel, AMD and others and
DWARF info:
# To get memory access samples in kernel for 1 second (on Intel)
$ perf mem record -a -K --ldlat=4 -- sleep 1
# Similar for the AMD (but it requires 6.3+ kernel for BPF filters)
$ perf mem record -a --filter 'mem_op == load || mem_op == store, ip > 0x8000000000000000' -- sleep 1
Then, amongst several modes of post processing, one can do things like:
$ perf report -s type,typeoff --hierarchy --group --stdio
...

This uses the existing annotate code, calling objdump to do the
disassembly, with improvements to avoid having this take too long,
but longer term a switch to a disassembler library, possibly
reusing code in the kernel will be pursued.
This is the initial implementation, please use it and report
impressions and bugs. Make sure the kernel-debuginfo packages match
the running kernel. The 'perf report' phase for non short perf.data
files may take a while.
There is a great article about it on LWN:

<SNIP>
perf top/report:
- Don't ignore job control, allowing control+Z + bg to work.
- Add s390 raw data interpretation for PAI (Processor Activity
Instrumentation) counters.
perf archive:
- Add new option '--all' to pack perf.data with DSOs.
- Add new option '--unpack' to expand tarballs.
Initialization speedups:
- Lazily initialize zstd streams to save memory when not using it.
- Lazily allocate/size mmap event copy.
- Lazy load kernel symbols in 'perf record'.
- Be lazier in allocating lost samples buffer in 'perf record'.
- Don't synthesize BPF events when disabled via the command line
(perf record --no-bpf-event).
Assorted improvements:
- Show note on AMD systems that the :p, :pp, :ppp and :P are all the
same, as IBS (Instruction Based Sampling) is used and it is
inherentely precise, not having levels of precision like in Intel
systems.
- When 'cycles' isn't available, fall back to the "task-clock" event
when not system wide, not to 'cpu-clock'.
- Add --debug-file option to redirect debug output, e.g.:
$ perf --debug-file /tmp/perf.log record -v true
- Shrink 'struct map' to under one cacheline by avoiding function
pointers for selecting if addresses are identity or DSO relative,
and using just a byte for some boolean struct members.
- Resolve the arch specific strerrno just once to use in
perf_env__arch_strerrno().
- Reduce memory for recording PERF_RECORD_LOST_SAMPLES event.
Assorted fixes:
- Fix the default 'perf top' usage on Intel hybrid systems, now it
starts with a browser showing the number of samples for Efficiency
(cpu_atom/cycles/P) and Performance (cpu_core/cycles/P). This
behaviour is similar on ARM64, with its respective set of
big.LITTLE processors.
- Fix segfault on build_mem_topology() error path.
- Fix 'perf mem' error on hybrid related to availability of mem event
in a PMU.
- Fix missing reference count gets (map, maps) in the db-export code.
- Avoid recursively taking env->bpf_progs.lock in the 'perf_env'
code.
- Use the newly introduced maps__for_each_map() to add missing
locking around iteration of 'struct map' entries.
- Parse NOTE segments until the build id is found, don't stop on the
first one, ELF files may have several such NOTE segments.
- Remove 'egrep' usage, its deprecated, use 'grep -E' instead.
- Warn first about missing libelf, not libbpf, that depends on
libelf.
- Use alternative to 'find ... -printf' as this isn't supported in
busybox.
- Address python 3.6 DeprecationWarning for string scapes.
- Fix memory leak in uniq() in libsubcmd.
- Fix man page formatting for 'perf lock'
- Fix some spelling mistakes.
perf tests:
- Fail shell tests that needs some symbol in perf itself if it is
stripped. These tests check if a symbol is resolved, if some hot
function is indeed detected by profiling, etc.
- The 'perf test sigtrap' test is currently failing on PREEMPT_RT,
skip it if sleeping spinlocks are detected (using BTF) and point to
the mailing list discussion about it. This test is also being
skipped on several architectures (powerpc, s390x, arm and aarch64)
due to other pending issues with intruction breakpoints.
- Adjust test case perf record offcpu profiling tests for s390.
- Fix 'Setup struct perf_event_attr' fails on s390 on z/VM guest,
addressing issues caused by the fallback from cycles to task-clock
done in this release.
- Fix mask for VG register in the user-regs test.
- Use shellcheck on 'perf test' shell scripts automatically to make
sure changes don't introduce things it flags as problematic.
- Add option to change objdump binary and allow it to be set via
'perf config'.
- Add basic 'perf script', 'perf list --json" and 'perf diff' tests.
- Basic branch counter support.
- Make DSO tests a suite rather than individual.
- Remove atomics from test_loop to avoid test failures.
- Fix call chain match on powerpc for the record+probe_libc_inet_pton
test.
- Improve Intel hybrid tests.
Vendor event files (JSON):
powerpc:
- Update datasource event name to fix duplicate events on IBM's
Power10.
- Add PVN for HX-C2000 CPU with Power8 Architecture.
Intel:
- Alderlake/rocketlake metric fixes.
- Update emeraldrapids events to v1.02.
- Update icelakex events to v1.23.

https://github.com/riscv-software-src/opensbi/blob/master/docs/platform/thead-c9xx.md
ARM64:
- Remove UTF-8 characters from cmn.json, that were causing build
failure in some distros.
- Add core PMU events and metrics for Ampere One X.
- Rename Ampere One's BPU_FLUSH_MEM_FAULT to GPC_FLUSH_MEM_FAULT
libperf:
- Rename several perf_cpu_map constructor names to clarify what they
really do.
- Ditto for some other methods, coping with some issues in their
semantics, like perf_cpu_map__empty() ->
perf_cpu_map__has_any_cpu_or_is_empty().
- Document perf_cpu_map__nr()'s behavior
perf stat:
- Exit if parse groups fails.
- Combine the -A/--no-aggr and --no-merge options.
- Fix help message for --metric-no-threshold option.
Hardware tracing:
ARM64 CoreSight:
- Bump minimum OpenCSD version to ensure a bugfix is present.
- Add 'T' itrace option for timestamp trace
- Set start vm addr of exectable file to 0 and don't ignore first
sample on the arm-cs-trace-disasm.py 'perf script'"

perf test 17 'Setup struct perf_event_attr' fails on s390 z/VM guest,
using linux-next kernel.
Root cause is the fall-back from hardware counter cycles
perf_event_attr:
type 0 (PERF_TYPE_HARDWARE)
size 136
config 0 (PERF_COUNT_HW_CPU_CYCLES)
{ sample_period, sample_freq } 4000
sample_type IP|TID|TIME|ADDR|PERIOD|DATA_SRC
read_format ID|LOST
which returns -ENOENT on s390 z/VM guest. This causes the code to fall
back to software counter task-clock, as can be seen in the debug output:
------------------------------------------------------------
perf_event_attr:
type 1 (PERF_TYPE_SOFTWARE)
size 136
config 0x1 (PERF_COUNT_SW_TASK_CLOCK) <-here
{ sample_period, sample_freq } 4000
sample_type IP|TID|TIME|ADDR|PERIOD|DATA_SRC
read_format ID|LOST
This succeeds on s390 z/VM guest.
This successful installation of the counter task-clock is not listed in
the expected results and the test case fails.
This is caused by commit eb2eac0c7b618033 ("perf evsel: Fallback to
"task-clock" when not system wide") which introduced fall back from
event 'cycles' to event 'task-clock'.
To fix this on s390 allow event number 0 (cycles) and event number 1
(task-clock) as expected result.
Output before:
# ./perf test -Fv 17
17: Setup struct perf_event_attr :
--- start ---

FAILED './tests/attr/test-record-graph-default' - match failure
---- end ----

#
Output after:

The addr_location map and maps fields in the inner loop were missing
calls to map__get()/maps__get(). The subsequent addr_location__exit()
call in each loop puts the map/maps fields causing use-after-free
aborts.
This issue reproduces on at least arm64 and x86_64 with something
simple like `perf record -g ls` followed by `perf script -s script.py`
with the following script:
perf_db_export_mode = True
perf_db_export_calls = False
perf_db_export_callchains = True
def sample_table(*args):
print(f'sample_table({args})')
def call_path_table(*args):
print(f'call_path_table({args}')
Committer testing:
This test, just introduced by Ian Rogers, now passes, not segfaulting
anymore:
# perf test "perf script tests"
95: perf script tests : Ok
#

In its infinite wisdom, by default, SLang sets susp undef, and this can
only be un-done by calling SLtty_set_suspend_state(true). After every
SLang_init_tty().
Additionally, no provisions are made for maintaining the teletype
attributes across suspend/continue (outside of curses emulation
mode(?!), which provides full support, naturally), so we need to save
and restore the flags ourselves, as well as reset the text colours when
going under. We need to also re-draw the screen, and raising SIGWINCH,
shockingly, Just Works.
The correct solution would be to Not Use SLang, but as a stop-gap,
this makes TUI 'perf report' usable.

a PMU for the alderlake UNCORE_FREQ metric.
Conversion script updated in:
https://github.com/intel/perfmon/pull/126
Committer testing:
Before this patch the "perf all metricgroups test" was failing, now:
root@number:~# perf test metric
10: PMU events :
10.3: Parsing of PMU event table metrics : Ok
10.4: Parsing of PMU event table metrics with fake PMUs : Ok
10.5: Parsing of metric thresholds with fake PMUs : Ok

98: perf stat metrics (shadow stat) test : Skip
101: perf all metricgroups test : Ok
102: perf all metrics test : FAILED!
107: perf metrics value validation : Ok
root@number:~#
Test 102 is failing for another reason, not being able to get as many
counters as needed, Ian Rogers suggested disabling the NMI watchdog to
have more counters available:
root@number:/home/acme# cat /proc/sys/kernel/nmi_watchdog

root@number:/home/acme# echo 0 > /proc/sys/kernel/nmi_watchdog
root@number:/home/acme# perf test 102

The cpu-cycles event is both a legacy event and declared in
/sys/devices/cpu_core/events/cpu-cycles. The cycles event is a legacy
event but with no sysfs version.
Add a test that the sysfs version is preferred to the legacy for
cpu-cycles, while for cycles we use the legacy version.

The legacy events cpu-cycles and instructions have sysfs event
equivalents on x86 (see /sys/devices/cpu_core/events).
As sysfs/JSON events are now higher in priority than legacy events this
causes the hybrid test expectations not to be met.
To fix this switch to legacy events that don't have sysfs versions,
namely cpu-cycles becomes cycles and instructions becomes branches.
Fixes: a24d9d9dc096fc0d ("perf parse-events: Make legacy events lower priority than sysfs/JSON")

Make the jevents parser aware of the Unified Memory Controller (UMC) PMU
and add events taken from Section 8.2.1 "UMC Performance Monitor Events"
of the Processor Programming Reference (PPR) for AMD Family 19h Model 11h
processors. The events capture UMC command activity such as CAS, ACTIVATE,
PRECHARGE etc. while the metrics derive data bus utilization and memory
bandwidth out of these events.

Support data type annotation with new --data-type option. It internally
uses type sort key to collect sample histogram for the type and display
every members like below.
$ perf annotate --data-type
...
Annotate type: 'struct cfs_rq' in [kernel.kallsyms] (13 samples):
============================================================================
samples offset size field
13 0 640 struct cfs_rq {
2 0 16 struct load_weight load {
2 0 8 unsigned long weight;
0 8 4 u32 inv_weight;
};
0 16 8 unsigned long runnable_weight;
0 24 4 unsigned int nr_running;
1 28 4 unsigned int h_nr_running;
...
For simplicity it prints the number of samples per field for now.
But it should be easy to show the overhead percentage instead.
The number at the outer struct is a sum of the numbers of the inner
members. For example, struct cfs_rq got total 13 samples, and 2 came
from the load (struct load_weight) and 1 from h_nr_running. Similarly,
the struct load_weight got total 2 samples and they all came from the
weight field.
I've added two new flags in the symbol_conf for this. The
annotate_data_member is to get the members of the type. This is also
needed for perf report with typeoff sort key. The annotate_data_sample
is to update sample stats for each offset and used only in annotate.
Currently it only support stdio output mode, TUI support can be added
later.
Committer testing:
With the perf.data from the previous csets, a very simple, short
duration one:
# perf annotate --data-type
Annotate type: 'struct list_head' in [kernel.kallsyms] (1 samples):
============================================================================
samples offset size field
1 0 16 struct list_head {
0 0 8 struct list_head* next;
1 8 8 struct list_head* prev;
};
Annotate type: 'char' in [kernel.kallsyms] (1 samples):
============================================================================
samples offset size field
1 0 1 char ;

Add child member field if the current type is a composite type like a
struct or union. The member fields are linked in the children list and
do the same recursively if the child itself is a composite type.
Add 'self' member to the annotated_data_type to handle the members in
the same way.

access. Add mem_type field to hist_entry struct to save the type. If
hist_entry__get_data_type() returns NULL, it'd use the 'unknown_type'

It's the function to find out the type info from the given sample data
and will be called from the hist_entry sort logic when 'type' sort key
is used.
It first calls objdump to disassemble the instructions and figure out
information about memory access at the location. Maybe we can do it
better by analyzing the instruction directly, but I'll leave it for
later work.
The memory access is determined by checking instruction operands to
have "(" and then extract register name and offset. It'll return NULL
if no data type is found.

The annotate_get_insn_location() is to get the detailed information of
instruction locations like registers and offset. It has source and
target operands locations in an array. Each operand can have a register
and an offset. The offset is meaningful when mem_ref flag is set.

The evsel__get_arch() is to get architecture info from the environment.
It'll be used by other places later so let's factor it out.
Also add arch__is() to check the arch info by name.
Committer notes:
"get" is usually associated with refcounting, so we better rename this
at some point to a better name.

To aggregate accesses to the same data type, add 'data_types' tree in
DSO to maintain data types and find it by name and size.
It might have different data types that happen to have the same name,
so it also compares the size of the type.
Even if it doesn't 100% guarantee, it reduces the possibility of
mis-handling of such conflicts.
And I don't think it's common to have different types with the same
name.
Committer notes:
Very few cases on the Linux kernel, but there are some different types
with the same name, unsure if there is a debug mode in libbpf dedup that
warns about such cases, but there are provisions in pahole for that,
see:
"emit: Notice type shadowing, i.e. multiple types with the same name (enum, struct, union, etc)"

The find_data_type() is to get a data type from the memory access at the
given address (IP) using a register and an offset.
It requires DWARF debug info in the DSO and searches the list of
variables and function parameters in the scope.
In a pseudo code, it does basically the following:
find_data_type(dso, ip, reg, offset)
{
pc = map__rip_2objdump(ip);
CU = dwarf_addrdie(dso->dwarf, pc);
scopes = die_get_scopes(CU, pc);
for_each_scope(S, scopes) {
V = die_find_variable_by_reg(S, pc, reg);
if (V && V.type == pointer_type) {
T = die_get_real_type(V);
if (offset < T.size)
return T;
}
}
return NULL;
}
Committer notes:
The 'size' variable in check_variable() is 64-bit, so use PRIu64 and
inttypes.h to debug it.
Ditto at find_data_type_die().

The get_dwarf_regnum() returns a DWARF register number from a register
name string according to the psABI. Also add two pseudo encodings of
DWARF_REG_PC which is a register that are used by PC-relative addressing
and DWARF_REG_FB which is a frame base register. They need to be
handled in a special way.

The die_get_typename_from_type() is to get the name of the given DIE in
C-style type name.
The difference from die_get_typename() is that it does not retrieve the
DW_AT_type and use the given DIE directly. This will be used when users
know the type DIE already.

cmn.json contains UTF-8 characters in brief description which
could break the perf build on some distros.
Fix this issue by removing the UTF-8 characters from cmn.json.
without this fix:
$find tools/perf/pmu-events/ -name "*.json" | xargs file -i | grep -v us-ascii
tools/perf/pmu-events/arch/arm64/arm/cmn/sys/cmn.json: application/json; charset=utf-8
with it:
$ file -i tools/perf/pmu-events/arch/arm64/arm/cmn/sys/cmn.json

Maps are sometimes made overlapping, in particular kernel maps. If the
end of a map overlaps the start of the next, shorten the overlapping
map. This should remove potential non-determinism in maps__find, ie
finding maps by address.

Rename to maps__fixup_overlap_and_insert() as the given mapping is
always inserted. Factor out first_ending_after() as a utility
function. Minor variable name changes. Switch to using debug_file()
rather than passing a debug FILE*.

Some dumping call backs need to be passed a FILE*. Expose debug file
via an accessor API for a consistent way to do this. Catch the
unlikely failure of it not being set. Switch two cases where stderr
was being used instead of debug_file.

Removing maps wasn't being done under the write lock. Similar to
maps__for_each_map(), iterate the entries but in this case remove the
entry based on the result of the callback. If an entry was removed
then maps_by_name() also needs updating, so add missed flush.
In dso__load_kcore(), the test of map to save would always be false with
REFCNT_CHECKING because of a missing RC_CHK_ACCESS/RC_CHK_EQUAL.

file to 0
For exectable ELF file, which e_type is ET_EXEC, dso start address is a
absolute address other than offset. Just set vm_start to zero when dso
start is 0x400000, which means it is a exectable file.

Archives generated by the command 'perf archive' have to be unpacked
manually.
Following the addition of option '--all' now there also exist a nested
structure of tars, and after further discussion with Red Hat Global
Support Services, they found a feature correctly unpacking archives of
'perf archive' convenient.
Option '--unpack' of 'perf archive' unpacks archives generated by the
command 'perf archive' as well as archives generated when used with
option '--all'.
The 'perf.data' file is placed in the current directory, while debug
symbols are unpacked in '~/.debug' directory. A tar filename can be
passed as an argument, and if not provided the command tries to find a
viable perf.tar file for unpacking.

'perf archive' has limited functionality and people from Red Hat Global
Support Services sent a request for a new feature that would pack
perf.data file together with an archive with debug symbols created by
the command 'perf archive' as customers were being confused and often
would forget to send perf.data file with the debug symbols.
With this patch 'perf archive' now accepts an option '--all' that
generates archive 'perf.all-hostname-date-time.tar.bz2' that holds file
'perf.data' and a sub-tar 'perf.symbols.tar.bz2' with debug symbols. The
functionality of the command 'perf archive' was not changed.
Committer testing:
Run 'perf record' on a Intel 14900K machine, hybrid:
root@number:~# perf record -a sleep 5s
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 4.006 MB perf.data (15427 samples) ]
root@number:~# perf archive --all
Now please run:
$ tar xvf perf.all-number-20231219-104854.tar.bz2 && tar xvf perf.symbols.tar.bz2 -C ~/.debug
wherever you need to run 'perf report' on.
