Function Documentation

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.

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

This function unregisters an existing virtio device.

int rproc_trigger_recovery

(

struct rproc *

rproc

)

rproc_trigger_recovery() - recover a remoteproc : the remote processor

The recovery is done by reseting all the virtio devices, that way all the rpmsg drivers will be reseted along with the remote processor making the remoteproc functional again.

This function can sleep, so it cannot be called from atomic context.

Definition at line 940 of file remoteproc_core.c.

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.
