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?.

Unfortunately, nobody's really worked on it, as far as I know. It would be great to see SATA target support, though. Jeff ^ permalink raw reply [flat|nested] 6+ messages in thread

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. http://www.marvell.com/products/processors/embedded/kirkwood/FS_88F6180_9x_6281_OpenSource.pdf saeed ^ permalink raw reply [flat|nested] 6+ messages in thread
