31  * The event mechanism is based on a pair of event buffers (buffers A and
32  * B) at fixed locations in the target's memory. The host processes one
33  * buffer while the other buffer continues to collect events. If the host
34  * is not processing events, an interrupt is issued to signal that a buffer
35  * is ready. Once the host is done with processing events from one buffer,
36  * it signals the target (with an ACK interrupt) that the event buffer is
37  * free.
