perf record: Add clockid parameter
Teach perf-record about the new perf_event_attr::{use_clockid, clockid} fields. Add a simple parameter to set the clock (if any) to be used for the events to be recorded into the data file. Since we store the entire perf_event_attr in the EVENT_DESC section we also already store the used clockid in the data file. Signed-off-by: Peter Zijlstra (Intel) <> Acked-by: David Ahern <> Cc: "H.
