From 0d0f9e540d940a48b91cbea1657794d44b25aedf Mon Sep 17 00:00:00 2001 From: Ian Rogers Date: Fri, 25 Sep 2026 23:20:13 -0700 Subject: perf: Remove libpython support and legacy Python scripts 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.
