perf: Remove libpython support and legacy Python scripts

2026-09-26T18:54:54+00:00

Remove embedded Python interpreter support (libpython) from perf, as all Python scripts have been migrated to standalone scripts using the perf Python extension module. Changes include: - Remove libpython detection and build flags from Makefile.config. - Remove legacy Python script installation rules from Makefile.perf. - Delete tools/perf/util/scripting-engines/trace-event-python.c and tools/perf/scripts/python/Perf-Trace-Util/Context.c. - Remove Python scripting engine registration from trace-event-scripting.c. - Remove libpython from the supported features list in builtin-check.c and Documentation/perf-check.txt. - Delete the legacy Python scripts and bin wrappers in tools/perf/scripts/python/ and update shell tests.

The '--' prevented arguments from being passed to the script, such as: $ perf script report stackcollapse -i my_perf.data Signed-off-by: Michael Petlan Cc: Jiri Olsa Cc: Paolo Bonzini LPU-Reference: 20200427142327.21172-1-mpetlan@redhat.com Signed-off-by: Arnaldo Carvalho de Melo

perf script: Add stackcollapse.py script

2016-06-21T16:18:35+00:00

Add stackcollapse.py script as an example of parsing call chains, and also of using optparse to access command line options. The flame graph tools include a set of scripts that parse output from various tools (including "perf script"), remove the offsets in the function and collapse each stack to a single line. The website also says "perf report could have a report style [...] that output folded stacks directly, obviating the need for stackcollapse-perf.pl", so here it is. This script is a Python rewrite of stackcollapse-perf.pl, using the perf scripting interface to access the perf data directly from Python.
