|
*
|
|
* @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.
