| * @RP_MBOX_READY: informs the M3's that we're up and running. this is |
| * part of the init sequence sent that the M3 expects to see immediately |
| * after it is booted. |
| * |
| * @RP_MBOX_PENDING_MSG: informs the receiver that there is an inbound |
| * message waiting in its own receive-side vring. please note that currently |
| * this message is optional: alternatively, one can explicitly send the index |
| * of the triggered virtqueue itself. the preferred approach will be decided |
| * as we progress and experiment with those two different approaches. |
| * |
| * @RP_MBOX_CRASH: this message is sent if BIOS crashes |
| * |
| * @RP_MBOX_ECHO_REQUEST: a mailbox-level "ping" message. |
| * |
| * @RP_MBOX_ECHO_REPLY: a mailbox-level reply to a "ping" |
| * |
| * @RP_MBOX_ABORT_REQUEST: a "please crash" request, used for testing the |
| * recovery mechanism (to some extent). |
