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 <sys/stdint.h> 106#include <sys/stddef.h> 107#include <sys/param.h> 108#include <sys/queue.h> 109#include <sys/types.h> 110#include <sys/systm.h> 111#include <sys/kernel.h> 112#include <sys/bus.h> 113#include <sys/module.h> 114#include <sys/lock.h> 115#include <sys/mutex.h> 116#include <sys/condvar.h> 117#include <sys/sysctl.h> 118#include <sys/sx.h> 119#include <sys/unistd.h> 120#include <sys/callout.h> 121#include <sys/malloc.h> 122#include <sys/priv.h> 123 124#include <dev/usb/usb.h> 125#include <dev/usb/usbdi.h> 126#include <dev/usb/usbdi_util.h> 127#include "usbdevs.h" 128 129#include <dev/usb/quirk/usb_quirk.h> 130 131#include <cam/cam.h> 132#include <cam/cam_ccb.h> 133#include <cam/cam_sim.h> 134#include <cam/cam_xpt_sim.h> 135#include <cam/scsi/scsi_all.h> 136#include <cam/scsi/scsi_da.h> 137 138#include <cam/cam_periph.h> 139 140#ifdef USB_DEBUG 141#define DIF(m, x) \ 142 do { \ 143 if (umass_debug & (m)) { x ; } \ 144 } while (0) 145 146#define DPRINTF(sc, m, fmt, ...) \ 147 do { \ 148 if (umass_debug & (m)) { \ 149 printf("%s:%s: " fmt, \ 150 (sc) ?
