The * sc->sc_transform method is used to convert the commands into the appropriate * format (if at all necessary). For example, UFI requires all commands to be * 12 bytes in length amongst other things. * * The source code below is marked and can be split into a number of pieces * (in this order): * * - probe/attach/detach * - generic transfer routines * - BBB * - CBI * - CBI_I (in addition to functions from CBI) * - CAM (Common Access Method) * - SCSI * - UFI * - 8070i (ATAPI) * * The protocols are implemented using a state machine, for the transfers as * well as for the resets. The state machine is contained in umass_t_*_callback. * The state machine is started through either umass_command_start() or * umass_reset(). * * The reason for doing this is a) CAM performs a lot better this way and b) it * avoids using tsleep from interrupt context (for example after a failed * transfer). */ /* * The SCSI related part of this driver has been derived from the * dev/ppbus/vpo.c driver, by Nicolas Souchu (nsouch@FreeBSD.org). * * The CAM layer uses so called actions which are messages sent to the host * adapter for completion. The actions come in through umass_cam_action. The * appropriate block of routines is called depending on the transport protocol * in use. When the transfer has finished, these routines call * umass_cam_cb again to complete the CAM command. */ #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include "usbdevs.h" #include #include #include #include #include #include #include #define UMASS_EXT_BUFFER #ifdef UMASS_EXT_BUFFER /* this enables loading of virtual buffers into DMA */ #define UMASS_USB_FLAGS .ext_buffer=1, #else #define UMASS_USB_FLAGS #endif #if USB_DEBUG #define DIF(m, x) \ do { \ if (umass_debug & (m)) { x ; } \ } while (0) #define DPRINTF(sc, m, fmt, ...) \ do { \ if (umass_debug & (m)) { \ printf("%s:%s: " fmt, \ (sc) ?
