- * IRQ penalties are used to promote PCI IRQ balancing.  We set each ISA-
- * possible IRQ (0-15) with a default penalty relative to its feasibility
- * for PCI's use:
+ * "acpi_irq_balance" (default in APIC mode) enables ACPI to use PIC Interrupt
+ * Link Devices to move the PIRQs around to minimize sharing.
+ * 
+ * "acpi_irq_nobalance" (default in PIC mode) tells ACPI not to move any PIC IRQs
+ * that the BIOS has already set to active.  This is necessary because
+ * ACPI has no automatic means of knowing what ISA IRQs are used.  Note that
+ * if the BIOS doesn't set a Link Device active, ACPI needs to program it
+ * even if acpi_irq_nobalance is set.
+ *
+ * A tables of penalties avoids directing PCI interrupts to well known
+ * ISA IRQs. Boot params are available to over-ride the default table:
  *
- *   Never use:		0, 1, 2 (timer, keyboard, and cascade)
- *   Avoid using:	13, 14, and 15 (FP error and IDE)
- *   Penalize:		3, 4, 6, 7, 12 (known ISA uses)
+ * List interrupts that are free for PCI use.
+ * acpi_irq_pci=n[,m]
  *
- * Thus we're left with IRQs 5, 9, 10, 11, and everything above 15 (IO[S]APIC)
- * as 'best bets' for PCI use.
+ * List interrupts that should not be used for PCI:
+ * acpi_irq_isa=n[,m]
+ *
+ * Note that PCI IRQ routers have a list of possible IRQs,
+ * which may not include the IRQs this table says are available.
+ * 
+ * Since this heuristic can't tell the difference between a link
+ * that no device will attach to, vs. a link which may be shared
+ * by multiple active devices -- it is not optimal.
+ *
+ * If interrupt performance is that important, get an IO-APIC system
+ * with a pin dedicated to each device.  Or for that matter, an MSI
+ * enabled system.

+ * The File-backed Storage Gadget acts as a USB Mass Storage device,
+ * appearing to the host as a disk drive.  In addition to providing an
+ * example of a genuinely useful gadget driver for a USB device, it also
+ * illustrates a technique of double-buffering for increased throughput.
+ * Last but not least, it gives an easy way to probe the behavior of the
+ * Mass Storage drivers in a USB host.
+ *
+ * Backing storage is provided by a regular file or a block device, specified
+ * by the "file" module parameter.  Access can be limited to read-only by
+ * setting the optional "ro" module parameter.
+ *
+ * The gadget supports the Control-Bulk (CB), Control-Bulk-Interrupt (CBI),
+ * and Bulk-Only (also known as Bulk-Bulk-Bulk or BBB) transports, selected
+ * by the optional "transport" module parameter.  It also supports the
+ * following protocols: RBC (0x01), ATAPI or SFF-8020i (0x02), QIC-157 (0c03),
+ * UFI (0x04), SFF-8070i (0x05), and transparent SCSI (0x06), selected by
+ * the optional "protocol" module parameter.  For testing purposes the
+ * gadget will indicate that it has removable media if the optional
+ * "removable" module parameter is set.  In addition, the default Vendor ID,
+ * Product ID, and release number can be overridden.
+ *
+ * There is support for multiple logical units (LUNs), each of which has
+ * its own backing file.  The number of LUNs can be set using the optional
+ * "luns" module parameter (anywhere from 1 to 8), and the corresponding
+ * files are specified using comma-separated lists for "file" and "ro".
+ * The default number of LUNs is taken from the number of "file" elements;
+ * it is 1 if "file" is not given.  If "removable" is not set then a backing
+ * file must be specified for each LUN.  If it is set, then an unspecified
+ * or empty backing filename means the LUN's medium is not loaded.
+ *
+ * Requirements are modest; only a bulk-in and a bulk-out endpoint are
+ * needed (an interrupt-out endpoint is also needed for CBI).  The memory
+ * requirement amounts to two 16K buffers, size configurable by a parameter.
+ * Support is included for both full-speed and high-speed operation.
+ *
+ * Module options:
+ *
+ *	file=filename[,filename...]
+ *				Required if "removable" is not set, names of
+ *					the files or block devices used for
+ *					backing storage
+ *	ro=b[,b...]		Default false, booleans for read-only access
+ *	luns=N			Default N = number of filenames, number of
+ *					LUNs to support
+ *	transport=XXX		Default BBB, transport name (CB, CBI, or BBB)
+ *	protocol=YYY		Default SCSI, protocol name (RBC, 8020 or
+ *					ATAPI, QIC, UFI, 8070, or SCSI;
+ *					also 1 - 6)
+ *	removable		Default false, boolean for removable media
+ *	vendor=0xVVVV		Default 0x0525 (NetChip), USB Vendor ID
+ *	product=0xPPPP		Default 0xa4a5 (FSG), USB Product ID
+ *	release=0xRRRR		Override the USB release number (bcdDevice)
+ *	buflen=N		Default N=16384, buffer size used (will be
+ *					rounded down to a multiple of
+ *					PAGE_CACHE_SIZE)
+ *	stall			Default determined according to the type of
+ *					USB device controller (usually true),
+ *					boolean to permit the driver to halt
+ *					bulk endpoints
+ *
+ * If CONFIG_USB_FILE_STORAGE_TEST is not set, only the "file" and "ro"
+ * options are available; default values are used for everything else.
+ *
+ * The pathnames of the backing files and the ro settings are available in
+ * the attribute files "file" and "ro" in the lun<n> subdirectory of the
+ * gadget's sysfs directory.  If CONFIG_USB_FILE_STORAGE_TEST and the
+ * "removable" option are both set, writing to these files will simulate
+ * ejecting/loading the medium (writing an empty line means eject) and
+ * adjusting a write-enable tab.  Changes to the ro setting are not allowed
+ * when the medium is loaded.
+ *
+ * This gadget driver is heavily based on "Gadget Zero" by David Brownell.

+ *				Driver Design
+ *
+ * The FSG driver is fairly straightforward.  There is a main kernel
+ * thread that handles most of the work.  Interrupt routines field
+ * callbacks from the controller driver: bulk- and interrupt-request
+ * completion notifications, endpoint-0 events, and disconnect events.
+ * Completion events are passed to the main thread by wakeup calls.  Many
+ * ep0 requests are handled at interrupt time, but SetInterface,
+ * SetConfiguration, and device reset requests are forwarded to the
+ * thread in the form of "exceptions" using SIGUSR1 signals (since they
+ * should interrupt any ongoing file I/O operations).
+ *
+ * The thread's main routine implements the standard command/data/status
+ * parts of a SCSI interaction.  It and its subroutines are full of tests
+ * for pending signals/exceptions -- all this polling is necessary since
+ * the kernel has no setjmp/longjmp equivalents.  (Maybe this is an
+ * indication that the driver really wants to be running in userspace.)
+ * An important point is that so long as the thread is alive it keeps an
+ * open reference to the backing file.  This will prevent unmounting
+ * the backing file's underlying filesystem and could cause problems
+ * during system shutdown, for example.  To prevent such problems, the
+ * thread catches INT, TERM, and KILL signals and converts them into
+ * an EXIT exception.
+ *
+ * In normal operation the main thread is started during the gadget's
+ * fsg_bind() callback and stopped during fsg_unbind().  But it can also
+ * exit when it receives a signal, and there's no point leaving the
+ * gadget running when the thread is dead.  So just before the thread
+ * exits, it deregisters the gadget driver.  This makes things a little
+ * tricky: The driver is deregistered at two places, and the exiting
+ * thread can indirectly call fsg_unbind() which in turn can tell the
+ * thread to exit.  The first problem is resolved through the use of the
+ * REGISTERED atomic bitflag; the driver will only be deregistered once.
+ * The second problem is resolved by having fsg_unbind() check
+ * fsg->state; it won't try to stop the thread if the state is already
+ * FSG_STATE_TERMINATED.
+ *
+ * To provide maximum throughput, the driver uses a circular pipeline of
+ * buffer heads (struct fsg_buffhd).  In principle the pipeline can be
+ * arbitrarily long; in practice the benefits don't justify having more
+ * than 2 stages (i.e., double buffering).  But it helps to think of the
+ * pipeline as being a long one.  Each buffer head contains a bulk-in and
+ * a bulk-out request pointer (since the buffer can be used for both
+ * output and input -- directions always are given from the host's
+ * point of view) as well as a pointer to the buffer and various state
+ * variables.
+ *
+ * Use of the pipeline follows a simple protocol.  There is a variable
+ * (fsg->next_buffhd_to_fill) that points to the next buffer head to use.
+ * At any time that buffer head may still be in use from an earlier
+ * request, so each buffer head has a state variable indicating whether
+ * it is EMPTY, FULL, or BUSY.  Typical use involves waiting for the
+ * buffer head to be EMPTY, filling the buffer either by file I/O or by
+ * USB I/O (during which the buffer head is BUSY), and marking the buffer
+ * head FULL when the I/O is complete.  Then the buffer will be emptied
+ * (again possibly by USB I/O, during which it is marked BUSY) and
+ * finally marked EMPTY again (possibly by a completion routine).
+ *
+ * A module parameter tells the driver to avoid stalling the bulk
+ * endpoints wherever the transport specification allows.  This is
+ * necessary for some UDCs like the SuperH, which cannot reliably clear a
+ * halt on a bulk endpoint.  However, under certain circumstances the
+ * Bulk-only specification requires a stall.  In such cases the driver
+ * will halt the endpoint and set a flag indicating that it should clear
+ * the halt in software during the next device reset.  Hopefully this
+ * will permit everything to work correctly.
+ *
+ * One subtle point concerns sending status-stage responses for ep0
+ * requests.  Some of these requests, such as device reset, can involve
+ * interrupting an ongoing file I/O operation, which might take an
+ * arbitrarily long time.  During that delay the host might give up on
+ * the original ep0 request and issue a new one.  When that happens the
+ * driver should not notify the host about completion of the original
+ * request, as the host will no longer be waiting for it.  So the driver
+ * assigns to each ep0 request a unique tag, and it keeps track of the
+ * tag value of the request associated with a long-running exception
+ * (device-reset, interface-change, or configuration-change).  When the
+ * exception handler is finished, the status-stage response is submitted
+ * only if the current ep0 request tag is equal to the exception request
+ * tag.  Thus only the most recently received ep0 request will get a
+ * status-stage response.
+ *
+ * Warning: This driver source file is too long.  It ought to be split up
+ * into a header file plus about 3 separate .c files, to handle the details
+ * of the Gadget, USB Mass Storage, and SCSI protocols.

-/*
- * Header file used to associate behaviors with virtualized objects.
- *
- * A virtualized object is an internal, virtualized representation of
- * OS entities such as persistent files, processes, or sockets.  Examples
- * of virtualized objects include vnodes, vprocs, and vsockets.  Often
- * a virtualized object is referred to simply as an "object."
- *
- * A behavior is essentially an implementation layer associated with
- * an object.  Multiple behaviors for an object are chained together,
- * the order of chaining determining the order of invocation.  Each
- * behavior of a given object implements the same set of interfaces
- * (e.g., the VOP interfaces).
- *
- * Behaviors may be dynamically inserted into an object's behavior chain,
- * such that the addition is transparent to consumers that already have
- * references to the object.  Typically, a given behavior will be inserted
- * at a particular location in the behavior chain.  Insertion of new
- * behaviors is synchronized with operations-in-progress (oip's) so that
- * the oip's always see a consistent view of the chain.
- *
- * The term "interpostion" is used to refer to the act of inserting
- * a behavior such that it interposes on (i.e., is inserted in front
- * of) a particular other behavior.  A key example of this is when a
- * system implementing distributed single system image wishes to
- * interpose a distribution layer (providing distributed coherency)
- * in front of an object that is otherwise only accessed locally.
- *
- * Note that the traditional vnode/inode combination is simply a virtualized
- * object that has exactly one associated behavior.
- *
- * Behavior synchronization is logic which is necessary under certain
- * circumstances that there is no conflict between ongoing operations
- * traversing the behavior chain and those dunamically modifying the
- * behavior chain.  Because behavior synchronization adds extra overhead
- * to virtual operation invocation, we want to restrict, as much as
- * we can, the requirement for this extra code, to those situations
- * in which it is truly necessary.
- *
- * Behavior synchronization is needed whenever there's at least one class
- * of object in the system for which:
- * 1) multiple behaviors for a given object are supported,
- * -- AND --
- * 2a) insertion of a new behavior can happen dynamically at any time during
- *     the life of an active object,
- *	-- AND --
- *	3a) insertion of a new behavior needs to synchronize with existing
- *	    ops-in-progress.
- *	-- OR --
- *	3b) multiple different behaviors can be dynamically inserted at
- *	    any time during the life of an active object
- *	-- OR --
- *	3c) removal of a behavior can occur at any time during the life of
- *	    an active object.
- * -- OR --
- * 2b) removal of a behavior can occur at any time during the life of an
- *     active object

+/*
+ * Header file used to associate behaviors with virtualized objects.
+ *
+ * A virtualized object is an internal, virtualized representation of
+ * OS entities such as persistent files, processes, or sockets.  Examples
+ * of virtualized objects include vnodes, vprocs, and vsockets.  Often
+ * a virtualized object is referred to simply as an "object."
+ *
+ * A behavior is essentially an implementation layer associated with
+ * an object.  Multiple behaviors for an object are chained together,
+ * the order of chaining determining the order of invocation.  Each
+ * behavior of a given object implements the same set of interfaces
+ * (e.g., the VOP interfaces).
+ *
+ * Behaviors may be dynamically inserted into an object's behavior chain,
+ * such that the addition is transparent to consumers that already have
+ * references to the object.  Typically, a given behavior will be inserted
+ * at a particular location in the behavior chain.  Insertion of new
+ * behaviors is synchronized with operations-in-progress (oip's) so that
+ * the oip's always see a consistent view of the chain.
+ *
+ * The term "interpostion" is used to refer to the act of inserting
+ * a behavior such that it interposes on (i.e., is inserted in front
+ * of) a particular other behavior.  A key example of this is when a
+ * system implementing distributed single system image wishes to
+ * interpose a distribution layer (providing distributed coherency)
+ * in front of an object that is otherwise only accessed locally.
+ *
+ * Note that the traditional vnode/inode combination is simply a virtualized
+ * object that has exactly one associated behavior.
+ *
+ * Behavior synchronization is logic which is necessary under certain
+ * circumstances that there is no conflict between ongoing operations
+ * traversing the behavior chain and those dunamically modifying the
+ * behavior chain.  Because behavior synchronization adds extra overhead
+ * to virtual operation invocation, we want to restrict, as much as
+ * we can, the requirement for this extra code, to those situations
+ * in which it is truly necessary.
+ *
+ * Behavior synchronization is needed whenever there's at least one class
+ * of object in the system for which:
+ * 1) multiple behaviors for a given object are supported,
+ * -- AND --
+ * 2a) insertion of a new behavior can happen dynamically at any time during
+ *     the life of an active object,
+ *	-- AND --
+ *	3a) insertion of a new behavior needs to synchronize with existing
+ *	    ops-in-progress.
+ *	-- OR --
+ *	3b) multiple different behaviors can be dynamically inserted at
+ *	    any time during the life of an active object
+ *	-- OR --
+ *	3c) removal of a behavior can occur at any time during the life of
+ *	    an active object.
+ * -- OR --
+ * 2b) removal of a behavior can occur at any time during the life of an
+ *     active object
