CNXK product families can have a use case to allow PF and VF applications to communicate using mailboxes and also get notified of any interrupt that may occur on the device. Hence, a new raw device driver is added for such RVU LF devices. These devices can map to a PF or a VF which can send mailboxes to each other. The RVU LF device implements following features in the rawdev API:
- Register mailbox callbacks for the other side to process mailboxes. - Register interrupt handler callbacks. - Process mailbox. - Set range of message IDs allowed for communication.
