All the fusion driver does is pass message frames with SCSI_IO/cdbs. We have access to config pages that provide info on the topology, and lets use configure somethings. We have sas_iounit control, that allows use to reset phys and links. We have sata and smp passthrus, other than that, everything is down in firmware. If you want to know more about the affiliations, we will need to start an internal discussion with firmware folks. Let me know.
