Merge tag 'perf-tools-for-v6.17-2025-08-01' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools

Pull perf tools updates from Namhyung Kim:
"Build-ID processing goodies:

Build-IDs are content based hashes to link regions of memory to ELF
files in post processing. They have been available in distros for
quite a while:

$ file /bin/bash
/bin/bash: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV),
dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2,
BuildID[sha1]=707a1c670cd72f8e55ffedfbe94ea98901b7ce3a,
for GNU/Linux 3.2.0, stripped

It is possible to ask the kernel to get it from mmap executable
backing storage at time they are being put in place and send it as
metadata at that moment to have in perf.data.

Prefer that across the board to speed up 'record' time - it post
processes the samples to find binaries touched by any samples and
to save them with build-ID. It can skip reading build-ID in
userspace if it comes from the kernel.

perf record:

* Make --buildid-mmap default. The kernel can generate MMAP2 events
with a build-ID from ELF header. Use that by default instead of using
inode and device ID to identify binaries. It also can be disabled
with --no-buildid-mmap.

* Use BPF for -u/--uid option to sample processes belong to a user.
BPF can track user processes more accurately and the existing logic
often fails to get the list of processes due to race with reading the
/proc filesystem.

* Generate PERF_RECORD_BPF_METADATA when it profiles BPF programs and
they have variables starting with "bpf_metadata_". This will help to
identify BPF objects used in the profile. This has been supported in
bpftool for some time and allows the recording of metadata such as
commit hashes, versions, etc, that now gets recorded in perf.data as
well.

* Collect list of DSOs touched in the sample callchains as well as in
the sample itself. This would increase the processing time at the end
of record, but can improve the data quality.

perf stat:

* Add a new 'drm' pseudo-PMU support like in 'hwmon'. It can collect
DRM usage stats using fdinfo in /proc.

On my Intel laptop, it shows like below:

$ perf list drm
...

drm:
drm-active-stolen-system0
[Total memory active in one or more engines. Unit: drm_i915]
drm-active-system0

perf list

* Add description for software events. The description is in JSON format
and the event parser now can handle the software events like others
(for example, it's case-insensitive and subject to wildcard matching).

$ perf list software

List of pre-defined events (to be used in -e or -M):

software:
alignment-faults
[Number of kernel handled memory alignment faults. Unit: software]
bpf-output
[An event used by BPF programs to write to the perf ring buffer. Unit: software]
cgroup-switches
[Number of context switches to a task in a different cgroup. Unit: software]
context-switches
[Number of context switches [This event is an alias of cs]. Unit: software]
cpu-clock
[Per-CPU high-resolution timer based event. Unit: software]
cpu-migrations
[Number of times a process has migrated to a new CPU [This event is an alias of migrations]. Unit: software]
cs
[Number of context switches [This event is an alias of context-switches]. Unit: software]
dummy
[A placeholder event that doesn't count anything. Unit: software]
emulation-faults
[Number of kernel handled unimplemented instruction faults handled through emulation. Unit: software]
faults
[Number of page faults [This event is an alias of page-faults]. Unit: software]
major-faults
[Number of major page faults. Major faults require I/O to handle. Unit: software]
migrations
[Number of times a process has migrated to a new CPU [This event is an alias of cpu-migrations]. Unit: software]
minor-faults
[Number of minor page faults. Minor faults don't require I/O to handle. Unit: software]
page-faults
[Number of page faults [This event is an alias of faults]. Unit: software]
task-clock
[Per-task high-resolution timer based event. Unit: software]

perf ftrace:

* Add -e/--events option to perf ftrace latency to measure latency
between the two events instead of a function.

$ sudo perf ftrace latency -ab -e i915_request_wait_begin,i915_request_wait_end --hide-empty -- sleep 1
# DURATION | COUNT | GRAPH |

# statistics (in usec)
total time: 194915
avg time: 6961
max time: 12855
min time: 373
count: 28

* Add new function graph tracer options (--graph-opts) to display more
info like arguments and return value. They will be passed to the
kernel ftrace directly.

$ sudo perf ftrace -G vfs_write --graph-opts retval,retaddr
# tracer: function_graph

5) 0.845 us | } /* _raw_spin_lock_irqsave ret=0x292 */
...

Misc:

* Add perf archive --exclude-buildids <FILE> option to skip some binaries.
The format of the FILE should be same as an output of perf buildid-list.

* Get rid of dependency of libcrypto. It was just to get SHA-1 hash so
implement it directly like in the kernel. A side effect is that it
needs -fno-strict-aliasing compiler option (again, like in the kernel).

* Convert all shell script tests to use bash"

"perf report/top/annotate TUI:

- Accept the left arrow key as a Zoom out if done on the first column

- Show if source code toggle status in title, to help spotting bugs
with the various disassemblers (capstone, llvm, objdump)

- Provide feedback on unhandled hotkeys

Build:

- Better inform when certain features are not available with warnings
in the build process and in 'perf version --build-options' or 'perf -vv'

switch-in intervals using a BPF program. This can be fine tuned
using a --off-cpu-thresh knob

- Add 'tgid' sort key

perf mem/c2c:

- Add 'op', 'cache', 'snoop', 'dtlb' output fields

- Add support for 'ldlat' on AMD IBS (Instruction Based Sampling)

perf ftrace:

- Use process/session specific trace settings instead of messing with
the global ftrace knobs

perf trace:

- Implement syscall summary in BPF

- Support --summary-mode=cgroup

- Always print return value for syscalls returning a pid

- The rseq and set_robust_list don't return a pid, just -errno

perf lock contention:

- Symbolize zone->lock using BTF

- Add -J/--inject-delay option to estimate impact on application
performance by optimization of kernel locking behavior

perf stat:

- Improve hybrid support for the NMI watchdog warning

Symbol resolution:

- Handle 'u' and 'l' symbols in /proc/kallsyms, resolving some Rust
symbols

- Improve Rust demangler

- Do not default to recording all switch events

- Fix pattern matching with python3 on the SQL viewer script

arm64:

- Fixups for the hip08 hha PMU

Vendor events:

- Update Intel events/metrics files for alderlake, alderlaken,

skylake, skylakex, snowridgex, tigerlake, westmereep-dp,
westmereep-sp, westmereep-sx

python support:

- Add support for event counts in the python binding, add a
counting.py example

perf list:

- Display the PMU name associated with a perf metric in JSON

perf test:

- Hybrid improvements for metric value validation test

- Fix LBR test by ignoring idle task

- Add AMD IBS sw filter ana d'ldlat' tests

- Add 'perf trace --summary-mode=cgroup' test

- Add tests for the various language symbol demanglers

Miscellaneous:

- Allow specifying the cpu an event will be tied using '-e
event/cpu=N/'

- Sync various headers with the kernel sources

- Add annotations to use clang's -Wthread-safety and fix some
problems it detected

- Make dump_stack() use perf's symbol resolution to provide better
backtraces

- Intel TPEBS support cleanups and fixes. TPEBS stands for Timed PEBS
(Precision Event-Based Sampling), that adds timing info, the
retirement latency of instructions

- Various memory allocation (some detected by ASAN) and reference
counting fixes

- Add a 8-byte aligned PERF_RECORD_COMPRESSED2 to replace
PERF_RECORD_COMPRESSED

- Skip unsupported event types in perf.data files, don't stop when
finding one

- Improve lookups using hashmaps and binary searches"

Since there is no way to align compressed data in zstd compression, this
patch add a new event type `PERF_RECORD_COMPRESSED2`, which adds a field
`data_size` to specify the actual compressed data size.

The `header.size` contains the total record size, including the padding
at the end to make it 8-byte aligned.

Tested with `Zstd perf.data compression/decompression`

perf session: Skip unsupported new event types

`perf report` currently halts with an error when encountering
unsupported new event types (`event.type >= PERF_RECORD_HEADER_MAX`).

This patch modifies the behavior to skip these samples and continue
processing the remaining events.

Additionally, stops reporting if the new event size is not 8-byte
aligned.
