| 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. |
