* Event type definitions
*
* The virtual events are not really defined in the specs but are an artifact used
* to quickly and easily setup EAR and/or BTB. The event type encodes the exact feature
* which must be configured in combination with a counting monitor.
* For instance, DATA_EAR_CACHE_LAT4 is a virtual D-EAR cache event. If the user
* requests this event, this will configure a counting monitor to count DATA_EAR_EVENTS
* and PMC11 will be configured for cache mode. The latency is encoded in the umask, here
* it would correspond to 4 cycles.
