From b1fcd190bb3fc1234dca60390d171a4cc75b21b2 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Sun, 25 Aug 2019 20:17:52 +0200 Subject: [PATCH] libperf: Add PERF_RECORD_SAMPLE 'struct sample_event' to perf/event.h Move the PERF_RECORD_SAMPLE event definition to libperf's event.h header include. In order to keep libperf simple, we switch 'u64/u32/u16/u8' types used events to their generic '__u*' versions.
