Hi,
I am trying to make vdisk ( file disk ) to emulate as a SATA
drive. To do so, i thought of making a SATA port to target mode and
cross wire it with another SATA port ( initiator) and by mapping the
SATA target mode port with vdisk, the SATA initiator must detect the
vdisk as some SATA device to perform further. Is such scenario doable?
Is the place where i can find more details on how much scenario is
achievable and the details Marvell SATA support as target mode in
kernel-tree and its info supported chipsets?.
Regards,
Jayaraman.T

Unfortunately, nobody's really worked on it, as far as I know.
It would be great to see SATA target support, though.

Jayaraman,
I've implemented the target mode for the marvell sata controllers
(supported by sata_mv.c), but that wasn't based on the libata driver,
it was done on marvell's in house driver (GPL), please let me know if
you need reference code and information about the HW.

I would like try on the Marvell sata controller chip-set (HW).
Please let me know more details on hardware and its reference code.
Thanks in advance.

Here is the functional spec of the kw soc, this soc includes the sata
controller, this device supported by the sata_mv.c libata driver.
