[PATCH 0/4] perf tools: Support reading PERF_FORMAT_LOST (v2)

[Namhyung Kim]

Hello,

The kernel v6.0 added PERF_FORMAT_LOST which can read a number of lost
samples for the given event.  As it can change the output format of
read(2) and perf sample data, it needs to access them carefully.

Changes in v2)
 * add a comment in perf_evsel__read_group()  (Jiri)
 * simplify perf_evsel__adjust_values()  (Jiri)


You can get the code from 'perf/read-lost-v2' brach on

  git://git.kernel.org/pub/scm/linux/kernel/git/namhyung/linux-perf.git

Thanks,
Namhyung
