This is supported, support for it is explicitly enabled by the sunxi_ahci driver (which is just some glue otherwise). > PMP (Port Multiplier Protocol) This may be supported, someone needs to test, AFAIK the hardware advertises it, but it is explicitly disabled by the sunxi_ahci glue. > CBS (Command Based Switching method for PMP) > FBS (FIS Based Switching method for PMP) See above.
