Add a test case for the python interpreter like below so that we can make sure it won't break again. To validate the effect of build-ID generation, it adds and removes the JIT'ed DSOs to/from the build-ID cache for the test. $ perf test -vv jitdump 84: python profiling with jitdump: --- start --- test child forked, pid 214316 Run python with -Xperf_jit [ perf record: Woken up 5 times to write data ] [ perf record: Captured and wrote 1.180 MB /tmp/__perf_test.perf.data.XbqZNm (140 samples) ] Generate JIT-ed DSOs using perf inject Add JIT-ed DSOs to the build-ID cache Check the symbol containing the script name Found 108 matching lines Remove JIT-ed DSOs from the build-ID cache ---- end(0) ---- 84: python profiling with jitdump : Ok Cc: Pablo Galindo <pablogsal@gmail.com> Link: https://docs.python.org/3/howto/perf_profiling.html#how-to-work-without-frame-pointers Signed-off-by: Namhyung Kim <namhyung@kernel.org> |
