A Dthunderx2-pmu.rst13 The DMC and L3C support up to 4 counters, while the CCPI2 supports up to 8
14 counters. Counters are independently programmable to different events and
15 can be started and stopped individually. None of the counters support an
16 overflow interrupt. DMC and L3C counters are 32-bit and read every 2 seconds.
17 The CCPI2 counters are 64-bit and assumed not to overflow in normal operation.
