rproc_vq_interrupt

)

int rproc_add_virtio_dev	(	struct rproc_vdev *	rvdev,
		int	id
	)

rproc_add_virtio_dev() - register an rproc-induced virtio device : the remote vdev

This function registers a virtio device. This vdev's partent is the rproc device.

Returns 0 on success or an appropriate error value otherwise.

void rproc_remove_virtio_dev

(

struct rproc_vdev *

rvdev

)

rproc_remove_virtio_dev() - remove an rproc-induced virtio device : the remote vdev

This function unregisters an existing virtio device.

irqreturn_t rproc_vq_interrupt	(	struct rproc *	rproc,
		int	notifyid
	)

rproc_vq_interrupt() - tell remoteproc that a virtqueue is interrupted : handle to the remote processor : index of the signalled virtqueue (unique per this )

This function should be called by the platform-specific rproc driver, when the remote processor signals that a specific virtqueue has pending messages available.

Returns IRQ_NONE if no message was found in the virtqueue, and otherwise returns IRQ_HANDLED.
