Is there a test driver for the > 88se63xx/64xx drivers available in 10.1 or -stable? I'm afraid there is no such one. That family of controllers is neither mvs(4) nor ahci(4). It is completely separate design, providing quite low-level interface to SAS ports (that means that support for wide ports, expanders, target mapping, etc. should be done manually inside the driver). I had a wish to implement it at some point, but had no documentation. Now I have some documentation and even some (old now) hardware, but not sure how much widespread/applicable are those chips now. Complains like that happen not so often and I am not sure I want to spend few months of work on discontinued hardware. Has Marvell released anything new from that line, like 12Gbps SAS, that could be interesting? -- Alexander Motin
