The 67 * sc->sc_transform method is used to convert the commands into the appropriate 68 * format (if at all necessary). For example, UFI requires all commands to be 69 * 12 bytes in length amongst other things. 70 * 71 * The source code below is marked and can be split into a number of pieces 72 * (in this order): 73 * 74 * - probe/attach/detach 75 * - generic transfer routines 76 * - BBB 77 * - CBI 78 * - CBI_I (in addition to functions from CBI) 79 * - CAM (Common Access Method) 80 * - SCSI 81 * - UFI 82 * - 8070i (ATAPI) 83 * 84 * The protocols are implemented using a state machine, for the transfers as 85 * well as for the resets. The state machine is contained in umass_t_*_callback. 86 * The state machine is started through either umass_command_start() or 87 * umass_reset(). 88 * 89 * The reason for doing this is a) CAM performs a lot better this way and b) it 90 * avoids using tsleep from interrupt context (for example after a failed 91 * transfer). 92 */ 93 94/* 95 * The SCSI related part of this driver has been derived from the 96 * dev/ppbus/vpo.c driver, by Nicolas Souchu (nsouch@FreeBSD.org). 97 * 98 * The CAM layer uses so called actions which are messages sent to the host 99 * adapter for completion. The actions come in through umass_cam_action. The 100 * appropriate block of routines is called depending on the transport protocol 101 * in use. When the transfer has finished, these routines call 102 * umass_cam_cb again to complete the CAM command. 103 */ 104 105#include "usbdevs.h" 106#include <dev/usb/usb.h> 107#include <dev/usb/usb_mfunc.h> 108#include <dev/usb/usb_error.h> 109 110#include <dev/usb/usb_core.h> 111#include <dev/usb/usb_util.h> 112#include <dev/usb/usb_busdma.h> 113#include <dev/usb/usb_request.h> 114#include <dev/usb/usb_debug.h> 115#include <dev/usb/usb_process.h> 116#include <dev/usb/usb_transfer.h> 117 118#include <cam/cam.h> 119#include <cam/cam_ccb.h> 120#include <cam/cam_sim.h> 121#include <cam/cam_xpt_sim.h> 122#include <cam/scsi/scsi_all.h> 123#include <cam/scsi/scsi_da.h> 124 125#include <cam/cam_periph.h> 126 127#if 1 128/* this enables loading of virtual buffers into DMA */ 129#define UMASS_USB_FLAGS .ext_buffer=1, 130#else 131#define UMASS_USB_FLAGS 132#endif 133 134#if USB_DEBUG 135#define DIF(m, x) \ 136 do { \ 137 if (umass_debug & (m)) { x ; } \ 138 } while (0) 139 140#define DPRINTF(sc, m, fmt, ...) \ 141 do { \ 142 if (umass_debug & (m)) { \ 143 printf("%s:%s: " fmt, \ 144 (sc) ?
