Initialize the number of accessible event counters Set the number of event counters accessible from all exception levels (MDCR_EL2.HPMN) to be the number of implemented event counters (PMCR_EL0.N). This might have other security implications later. Later work to investigate how Hafnium should handle access to event counters. Bug: 132394973 Change-Id: I7e63949dde2dcec58d929da4bb3e3efab5d3adee
