No, current perl code will pass 4 rather raw data structures to the script's "process_event": pevent->header, evel->attr, sample, sample->raw_data XPUSHs(sv_2mortal(newSVpvn((const char *)pevent, pevent->header.size))); XPUSHs(sv_2mortal(newSVpvn((const char *)&evsel->attr, sizeof(evsel->attr)))); XPUSHs(sv_2mortal(newSVpvn((const char *)sample, sizeof(*sample)))); XPUSHs(sv_2mortal(newSVpvn((const char *)sample->raw_data, sample->raw_size))); my patch only have the last 3 ones plus extra event_name/dso_name/symobl, while missing the "pevent->header", do you want me to add it? > > > > The first two patches in this series don't apply anymore, please find > > > them attached fixed, please check if they work as expected. > > > Thanks a lot for fixing them, I'll generate perf tool patch against the > > "perf/core" branch of your git tree on kernel.org from now on. > > > > Btw, I have 2 more python scripts based on these patches, will add them > > to this serie for your review. > > Ok, will take a look at them.
