Merge tag 'perf-tools-for-v6.14-2025-01-21' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools

Pull perf-tools updates from Namhyung Kim:
"There are a lot of changes in the perf tools in this cycle.

build:

- Use generic syscall table to generate syscall numbers on supported
archs

- This also enables to get rid of libaudit which was used for syscall
numbers

- Remove python2 support as it's deprecated for years

- Fix issues on static build with libzstd

perf record:

- Intel-PT supports "aux-action" config term to pause or resume
tracing in the aux-buffer. Users can start the intel_pt event as
"started-paused" and configure other events to control the Intel-PT
tracing:

# perf record --kcore -e intel_pt/aux-action=start-paused/ \
-e syscalls:sys_enter_newuname/aux-action=resume/ \
-e syscalls:sys_exit_newuname/aux-action=pause/ -- uname

This requires kernel support (which was added in v6.13)

perf lock:

- 'perf lock contention' command has an ability to symbolize locks in
dynamically allocated objects using slab cache name when it runs
with BPF. Those dynamic locks would have "&" prefix in the name to
distinguish them from ordinary (static) locks

# perf lock con -abl -E 5 sleep 1
contended total wait max wait avg wait address symbol

2 1.95 us 1.77 us 975 ns ffff9d5e852d3498 &task_struct (mutex)
1 1.18 us 1.18 us 1.18 us ffff9d5e852d3538 &task_struct (mutex)
4 1.12 us 354 ns 279 ns ffff9d5e841ca800 &kmalloc-cg-512 (mutex)
2 859 ns 617 ns 429 ns ffffffffa41c3620 delayed_uprobe_lock (mutex)
3 691 ns 388 ns 230 ns ffffffffa41c0940 pack_mutex (mutex)

This also requires kernel/BPF support (which was added in v6.13)

perf ftrace:

- 'perf ftrace latency' command gets a couple of options to support
linear buckets instead of exponential. Also it's possible to
specify max and min latency for the linear buckets:

# perf ftrace latency -abn -T switch_mm_irqs_off --bucket-range=100 \
--min-latency=200 --max-latency=800 -- sleep 1
# DURATION | COUNT | GRAPH |
0 - 200 ns | 186 | ### |
200 - 300 ns | 256 | ##### |
300 - 400 ns | 364 | ####### |
400 - 500 ns | 223 | #### |
500 - 600 ns | 111 | ## |
600 - 700 ns | 41 | |
700 - 800 ns | 141 | ## |
800 - ... ns | 169 | ### |

# statistics (in nsec)
total time: 2162212
avg time: 967
max time: 16817
min time: 132
count: 2236

- As you can see in the above example, it nows shows the statistics
at the end so that users can see the avg/max/min latencies easily

- 'perf ftrace profile' command has --graph-opts option like 'perf
ftrace trace' so that it can control the tracing behaviors in the
same way. For example, it can limit the function call depth or
threshold

perf script:

- Improve physical memory resolution in 'mem-phys-addr' script by
parsing /proc/iomem file

# perf script mem-phys-addr -- find /
...
Event: mem_inst_retired.all_loads:P
Memory type count percentage
---------------------------------------- ---------- ----------
100000000-85f7fffff : System RAM 8929 69.7

100000-89c01fff : System RAM 18 0.1
8a22c000-8df6efff : System RAM 5 0.0

Others:

- 'perf test' gets --runs-per-test option to run the test cases
repeatedly. This would be helpful to see if it's flaky

- Add 'parse_events' method to Python perf extension module, so that
users can use the same event parsing logic in the python code. One
more step towards implementing perf tools in Python. :)

- Support opening tracepoint events without libtraceevent. This will
be helpful if it won't use the tracing data like in 'perf stat'

- Update ARM Neoverse N2/V2 JSON events and metrics"

perf tools: Remove dependency on libaudit

All architectures now support HAVE_SYSCALL_TABLE_SUPPORT, so the flag is
no longer needed. With the removal of the flag, the related
GENERIC_SYSCALL_TABLE can also be removed.

libaudit was only used as a fallback for when HAVE_SYSCALL_TABLE_SUPPORT
was not defined, so libaudit is also no longer needed for any
architecture.

tools build: Add feature test for libelf with ZSTD

The macro ELFCOMPRESS_ZSTD defines the compress algorithm, which was
introduced in the commit ("libelf: Document and make ELFCOMPRESS_ZSTD
usable with old system elf.h") of the repository elfutils-0.188-67.
Therefore, libelf 0.189 and later versions require to link the libzstd
library.

Add a test for checking if libelf supports ZSTD algorithm. Pass the
macro ELFCOMPRESS_ZSTD as an argument to the elf_compress() function.
If the build succeeds, it means the feature is supported.

qspinlocks: note that this implementation of qspinlocks satisfies the

It also uses Ziccrse to provide the qspinlock implementation.

"perf record:

- Enable leader sampling for inherited task events. It was supported
only for system-wide events but the kernel started to support such
a setup since v6.12.

This is to reduce the number of PMU interrupts. The samples of the
leader event will contain counts of other events and no samples
will be generated for the other member events.

information like prediction, abort and cycles which is available
on Intel machines.

The HWMON provides various system information like CPU/GPU
temperature, fan speed and so on. Expose them as PMU events so that
users can see the values using perf stat commands.

Some metrics define thresholds to classify value ranges. It used to
be in a different color but it won't work for JSON.

Build:

- Make libunwind opt-in (LIBUNWIND=1) rather than opt-out.

The perf tools are generally built with libelf and libdw which has
unwinder functionality. The libunwind support predates it and no
need to have duplicate unwinders by default.

- Rename NO_DWARF=1 build option to NO_LIBDW=1 in order to clarify
it's using libdw for handling DWARF information.

Internals:

- Do not set exclude_guest bit in the perf_event_attr by default.

This was causing a trouble in AMD IBS PMU as it doesn't support the
bit. The bit will be set when it's needed later by the fallback
logic. Also update the missing feature detection logic to make sure
not clear supported bits unnecessarily.

- Run perf test in parallel by default and mark flaky tests
"exclusive" to run them serially at the end. Some test numbers are
changed but the test can complete in less than half the time.

JSON vendor events:

- Add AMD Zen 5 events and metrics.

- Add i.MX91 and i.MX95 DDR metrics

- Fix HiSilicon HIP08 Topdown metric name.

- Support compat events on PowerPC"
