Detailed Description

struct virtproc_info - virtual remote processor state : the virtio device : rx virtqueue : tx virtqueue : kernel address of rx buffers : kernel address of tx buffers : index of last tx buffer used : dma base addr of the buffers : protects svq, sbufs and sleepers, to allow concurrent senders. sending a message might require waking up a dozing remote processor, which involves sleeping, hence the mutex. : idr of local endpoints, allows fast retrieval : lock of the endpoints set : wait queue of sending contexts waiting for a tx buffers : number of senders that are waiting for a tx buffer : the bus's name service endpoint

This structure stores the rpmsg state of a given virtio remote processor device (there might be several virtio proc devices for each physical remote processor).
