[PATCH v1 00/49] perf: Complete transition to standalone Python scripts

[Ian Rogers <irogers@google.com>]

The perf script command has historically supported running Python and Perl
scripts by embedding libpython and libperl. That approach has several
drawbacks:
 - high overhead from constructing Python dictionaries for every event
   (whether used by the script or not),
 - complex build dependencies on specific Python/Perl libraries,
 - threading and interpreter lifecycle complications from embedding the
   interpreter inside perf,
 - no unified model for standalone scripts such as ilist.py, treport.py,
   tracepoint.py, and twatch.py.

Parts of this series were previously posted as part of the larger
"perf: Reorganize scripting support" series:
https://lore.kernel.org/linux-perf-users/20260428071903.1886173-1-irogers@google.com/
with earlier RFC and mailing list discussion at:
https://lore.kernel.org/linux-perf-users/20251029053413.355154-1-irogers@google.com/
https://lore.kernel.org/lkml/CAP-5=fWDqE8SYfOLZkg_0=4Ayx6E7O+h7uUp4NDeCFkiN4b7-w@mail.gmail.com/

From that earlier series, the prerequisite patches (header dependency cleanups,
evlist/evsel reference counting, initial perf.data and perf.session C extension
wrappers, callchain/brstack/stat/syscall/config accessors, perf.pyi type stubs,
LiveSession, and removal of embedded libperl support) have now been merged. We
are restarting the version number at v1 for the remaining patches, along with
additional C extension capabilities, build-time static analysis (mypy and
pylint), and review fixes.

Running scripts as standalone Python applications using the perf Python C
extension module provides a dramatic speedup. For example, with
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
```

The 49 patches in this series are organized into four groups:

1. Perf Python C Extension & Existing Script Updates (Patches 01-10):
   - Refine syscall_name()/syscall_id() argument parsing, callchain stubs, and
     session.find_thread() lookup in tools/perf/util/python.c and
     tools/perf/python/perf.pyi.
   - Clean up pylint warnings and improve `perf script -l` descriptions in
     existing standalone scripts (ilist.py, treport.py, tracepoint.py,
     twatch.py).
   - Expose destination address location attributes (addr_dso, addr_symbol,
     addr_sym_offset), branch/transaction fields, sym_offset, context_switch
     callbacks, and Intel PT call_return / itrace synthesis directly in the
     perf Python extension (many parts previously posted in
     https://lore.kernel.org/linux-perf-users/20260428071903.1886173-1-irogers@google.com/).
   - Allow KeyboardInterrupt to propagate cleanly in LiveSession.

2. Build-Time Python Static Analysis (Patches 11-14):
   - Clean up mypy and pylint warnings in tools/perf/pmu-events/ and
     tools/perf/tests/shell/lib/.
   - Make MYPY and PYLINT build checks enabled by default when mypy and
     pylint (>= 2.16.0) are installed, with NO_MYPY=1 and NO_PYLINT=1 opt-out
     controls (matching NO_SHELLCHECK=1), so all Python scripts in tools/perf
     are continuously type-checked and linted at build time.

3. Porting Legacy Python & Perl Scripts to tools/perf/python/ (Patches 15-45):
   - Previously sent as part of
     https://lore.kernel.org/linux-perf-users/20260428071903.1886173-1-irogers@google.com/
     and updated with static type annotations, mypy/pylint cleanups, and
     accompanying shell tests under tools/perf/tests/shell/. Sashiko-driven
     review and improvement was undertaken while porting so that the ported
     scripts are in the best shape possible:
     * Temporarily install tools/perf/python/ scripts during the transition
       (Patch 15).
     * General & profiling scripts: stat-cpi.py, mem-phys-addr.py,
       stackcollapse.py, flamegraph.py, gecko.py, event_analyzing_sample.py
       (Patches 16-21).
     * Syscall & I/O scripts (ported from legacy Python and Perl):
       syscall-counts.py, syscall-counts-by-pid.py,
       failed-syscalls-by-pid.py, failed-syscalls.py, sctop.py, rw-by-file.py,
       rw-by-pid.py, rwtop.py (Patches 22-29).
     * Scheduling, locking, MM & networking scripts: futex-contention.py,
       task-analyzer.py, sched-migration.py (with SchedGui.py),
       wakeup-latency.py, compaction-times.py, net_dropmonitor.py,
       netdev-times.py, check-perf-trace.py (Patches 30-37).
     * Hardware trace & architecture-specific scripts: arm-cs-trace-disasm.py,
       powerpc-hcalls.py, intel-pt-events.py (with libxed.py), and migrating
       the Intel PT virtual LBR test to the Python API (Patches 38-41).
     * Database export & viewer utilities: export-to-sqlite.py,
       export-to-postgresql.py, exported-sql-viewer.py, and parallel-perf.py
       (Patches 42-45).

4. Removing Embedded libpython & Updating Build, CLI, and Docs (Patches 46-49):
   - Previously sent as part of
     https://lore.kernel.org/linux-perf-users/20260428071903.1886173-1-irogers@google.com/ :
     * Remove embedded libpython support (scripting-engines/trace-event-python.c)
       and delete the legacy tools/perf/scripts/python/ directory (Patch 46).
     * Replace the libpython feature check with test-python-module.c and
       update Python script installation paths (Patch 47).
     * Update `perf script` (builtin-script.c) to execute standalone scripts
       directly and remove embedded scripting engine support (Patch 48).
     * Update perf man pages (perf-script.txt, perf-script-python.txt,
       perf-check.txt) for standalone Python scripts (Patch 49).
