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