44 * @file xl2cc_counter.h
46 * This header file contains APIs for configuring and controlling the event
47 * counters in PL310 L2 cache controller.
48 * PL310 has 2 event counters which can be used to count a variety of events
49 * like DRHIT, DRREQ, DWHIT, DWREQ, etc. This file defines configurations,
50 * where value configures the event counters to count a set of events.
52 * XL2cc_EventCtrInit API can be used to select a set of events and
53 * XL2cc_EventCtrStart configures the event counters and starts the counters.
54 * XL2cc_EventCtrStop diables the event counters and returns the counter values.
57 * MODIFICATION HISTORY:
