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. | ||

57 | * @RP_MBOX_ABORT_REQUEST: a "please crash" request, used for testing the | ||
58 | * recovery mechanism (to some extent). | ||
