[PATCH v2 00/58] perf: Reorganize scripting support

Ian Rogers
2026-04-23T03:55:39Z

The `perf script` command has long supported running Python and Perl
scripts by embedding `libpython` and `libperl`. This approach has
several drawbacks:
- overhead by creating Python dictionaries for every event (whether used or not),
- complex build dependencies on specific Python/Perl versions,
- complications with threading due to perf being the interpreter,
- no clear way to run standalone scripts like `ilist.py`.

This series takes a different approach with some initial
implementation posted as an RFC last October:
https://lore.kernel.org/linux-perf-users/20251029053413.355154-1-irogers@google.com/
with the motivation coming up on the mailing list earlier:
https://lore.kernel.org/lkml/CAP-5=fWDqE8SYfOLZkg_0=4Ayx6E7O+h7uUp4NDeCFkiN4b7-w@mail.gmail.com/

The changes remove the embedded `libpython` and `libperl` support from
`perf` entirely. Instead, they expand the existing `perf` Python
module to provide full access to perf data files and events, allowing
scripts to be run as standalone Python applications.

To demonstrate the benefits, we ported all existing Python and Perl
scripts to use the new Python session API. The performance improvement
is dramatic. For example, porting `mem-phys-addr.py`:

Before (using embedded libpython in `perf script`):
```
$ perf mem record -a sleep 1
$ time perf script tools/perf/scripts/python/mem-phys-addr.py
Event: cpu_core/mem-loads-aux/
Memory type count percentage
--------------------------------------- ---------- ----------
0-fff : Reserved 3217 100.0

real 0m3.754s
user 0m0.023s
sys 0m0.018s
```

After (using standalone Python script with `perf` module):
```
$ PYTHONPATH=/tmp/perf/python time python3 tools/perf/python/mem-phys-addr.py
Event: evsel(cpu_core/mem-loads-aux/)
Memory type count percentage
--------------------------------------- ---------- ----------
0-fff : Reserved 3217 100.0

real 0m0.106s
user 0m0.021s
sys 0m0.020s
```

This is a roughly 35x speedup!

The change is large (11285 insertions, 15963 deletions - net 4678
deletions) due to porting all existing perl and python code to the new
API. Gemini was used to achieve this and to improve the code
quality. Removing support may be controversial, however, the first 52
patches are additive and merging those would allow us to focus on the
remaining 6 patches that finalize the new `perf script` behavior.

** v2 Changes

Focus on addressing Sashiko, leak sanitizer and runtime issues.

*** 1. String Match and Event Name Accuracy

* Replaced loose substring event matching across the script suite with
exact matches or specific prefix constraints (`syscalls:sys_exit_`,
`evsel(skb:kfree_skb)`, etc.).

* Added `getattr()` safety checks to prevent script failures caused by
unresolved attributes from older kernel traces.

*** 2. OOM and Memory Protections

* Refactored `netdev-times.py` to compute and process network
statistics chronologically on-the-fly, eliminating an unbounded
in-memory list that caused Out-Of-Memory crashes on large files.

* Implemented threshold limits on `intel-pt-events.py` to cap memory
allocation during event interleaving.

* Optimized `export-to-sqlite.py` to periodically commit database
transactions (every 10,000 samples) to reduce temporary SQLite
journal sizes.

*** 3. Portability & Environment Independence

* Re-keyed internal tracking dictionaries in scripts like
`powerpc-hcalls.py` to use thread `PIDs` instead of `CPUs`, ensuring
correctness when threads migrate.

* Switched `net_dropmonitor.py` from host-specific `/proc/kallsyms`
parsing to `perf`'s built-in symbol resolution API.

* Added the `--iomem` parameter to `mem-phys-addr.py` to support
offline analysis of data collected on different architectures.

*** 4. Standalone Scripting Improvements

* Patched `builtin-script.c` to ensure `--input` parameters are
successfully passed down to standalone execution pipelines via
`execvp()`.

* Guarded against string buffer overflows during `.py` extension path
resolving.

*** 5. Code Cleanups

* Removed stale `perl` subdirectories from being detected by the TUI
script browser.

* Ran the entire script suite through `mypy` and `pylint` to achieve
strict static type checking and resolve unreferenced variables.
