hi, David reported issues with perf top loosing side band events so we moved mmap reading and hists processing into separated threads.
This patchset also adds dropping sample logic when the processing falls behind the reader thread. This way we get incomplete but current data in perf top.
Also available in: git://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git perf/fixes
thanks, jirka
