USB: mass storage: emulation of sat scsi_pass_thru with ATACB
I have got a cypress usb-ide bridge and I would like to tune or monitor my disk with tools like hdparm, hddtemp or smartctl. My controller support a way to send raw ATA command to the disk with something call atacb (see http://download.cypress.com.edgesuite.net/design_resources/datasheets/contents/cy7c68300c_8.pdf). Atacb support can be added for each application, but there is some disadvantages : - all application need to be patched - A race is possible if there other accesses, because the emulation can be split in 2 atacb scsi transactions. One for sending the command, one for reading the register (if ck_cond is set). I have implemented the emulation in usb-storage with a special proto_handler, and an unsual entry.
