hi,
after discussion with David, sending his change
updated into the new data file object.

David's original post:

Here's the change:
git://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git
perf/mmap1


Not having any luck with these patches. Basic use case:

perf trace record -a -- sleep 5
perf trace --summary

With your patches I get a parse error. With my latest versions
everything works clean.

hum,
perf trace --summary seems stuck in a loop, but that's no
different from current acme's perf/core.

D'oh. When writing the email I was trying to keep the command line small and in the process removed the -i /tmp/perf.data from the second command. Without it perf-trace runs in live mode; with it events are read from a file.
