You mean this faking of the SATA Control Registers? If so, this is a bit problematic ... SAS HBAs don't seem to come with SATA Control Registers (and certainly not when the device is remote over SAT). We do, however, have reasonable control of the phys via the transport class. Probably the best solution is to expand the ata transport class to abstract this phy control out into knobs users can twiddle and then put this back down to libata/libsas via callbacks they can each interpret.
