Transactions are sent via the master port passed rapirio port.

This function is used to initialize the fields of a resource for use as a mailbox resource. If device has a destination ID register, a destination ID is either assigned in enumeration mode or read from configuration space in discovery mode.


RapidIO turns out to be a sort of backplane interconnect intended mainly for embedded systems. Returns 0 on success. If a RIO device is found with a matching vid and didthe reference count to the device is incrememted and a pointer to its device structure is returned.

In this case, the necessary code looks like: As these devices become available, Linux will have the low-level infrastructure needed to support them. Returns 0 if successful. Tell if a device linu a given RapidIO capability. The RapidIO subsystem is integrated with the device model, so it provides the expected structures: Some entries under ‘rapidio: Requests ownership of an inbound mailbox resource and binds a callback function to the resource.
