I sit in the cube right next to John Lohmeyer, who heads the T10 committee. The firmware folks have not implemented 0xA1 or 0x85, and its not clear if and when they will. Today, the key people are at offsite meetings so I don't have an answer. I believe they are leaning more towards not, as we have the MPI_FUNCTION_SATA_PASSTHROUGH, which is exported thru ioctl path. Probably if its important on the Linux front, I could look into hooking the 0xA1, 0x85 opcodes in the driver, and porting them over to MPI_FUNCTION_SATA_PASSTHROUGH. How important is this? I can propose those alternatives inside LSI.
