/linux/Documentation/powerpc/
A Dpmu-ebb.rst53 existing "pinned" and "exclusive" attributes of perf_events. This means EBB
54 events will be given priority over other events, unless they are also pinned.
55 If an EBB event and a regular event are both pinned, then whichever is enabled
70 An EBB event must be created with the "pinned" and "exclusive" attributes set.
100 This behaviour occurs because the EBB event is pinned and exclusive. When the
101 EBB event is enabled it will force all other non-pinned events off the PMU. In
103 pinned on the PMU then the enable will not be successful.
