ARM virtual counter supports event stream. It can only trigger an event
when the trigger bit of CNTVCT_EL0 changes from 0 to 1 (or from 1 to 0),
so the actual period of event stream is 2 ^ (cntkctl_evnti + 1). For
example, when the trigger bit is 0, then it triggers an event for every
two cycles.
Friendly ping.
Is this an effective bugfix?
