+Description:	Maximum time allowed for periodic transfers per microframe (μs)
+
+		[ USB 2.0 sets maximum allowed time for periodic transfers per
+		  microframe to be 80%, that is 100 microseconds out of 125
+		  microseconds (full microframe).
+
+		  However there are cases, when 80% max isochronous bandwidth is
+		  too limiting. For example two video streams could require 110
+		  microseconds of isochronous bandwidth per microframe to work
+		  together. ]
+
+		Through this setting it is possible to raise the limit so that
+		the host controller would allow allocating more than 100
+		microseconds of periodic bandwidth per microframe.
+
+		Beware, non-standard modes are usually not thoroughly tested by
+		hardware designers, and the hardware can malfunction when this
+		setting differ from default 100.

+Supported chips:

+
+Author: Hans de Goede <hdegoede@redhat.com>
+
+
+Description
+-----------
+
+SMSC SCH5636 Super I/O chips include an embedded microcontroller for
+hardware monitoring solutions, allowing motherboard manufacturers to create
+their own custom hwmon solution based upon the SCH5636.
+
+Currently the sch5636 driver only supports the Fujitsu Theseus SCH5636 based
+hwmon solution. The sch5636 driver runs a sanity check on loading to ensure
+it is dealing with a Fujitsu Theseus and not with another custom SCH5636 based
+hwmon solution.
+
+The Fujitsu Theseus can monitor up to 5 voltages, 8 fans and 16
+temperatures. Note that the driver detects how many fan headers /
+temperature sensors are actually implemented on the motherboard, so you will
+likely see fewer temperature and fan inputs.
+
+An application note describing the Theseus' registers, as well as an
+application note describing the protocol for communicating with the
+microcontroller is available upon request. Please mail me if you want a copy.

+shm_rmid_forced:
+
+Linux lets you set resource limits, including how much memory one
+process can consume, via setrlimit(2).  Unfortunately, shared memory
+segments are allowed to exist without association with any process, and
+thus might not be counted against any resource limits.  If enabled,
+shared memory segments are automatically destroyed when their attach
+count becomes zero after a detach or a process termination.  It will
+also destroy segments that were created, but never attached to, on exit
+from the process.  The only use left for IPC_RMID is to immediately
+destroy an unattached segment.  Of course, this breaks the way things are
+defined, so some applications might stop working.  Note that this
+feature will do you no good unless you also configure your resource
+limits (in particular, RLIMIT_AS and RLIMIT_NPROC).  Most systems don't

+ * These macros are used to define the list of clobbered registers during a
+ * hypercall.  Technically, registers r0 and r3-r12 are always clobbered,
+ * but the gcc inline assembly syntax does not allow us to specify registers
+ * on the clobber list that are also on the input/output list.  Therefore,
+ * the lists of clobbered registers depends on the number of register
+ * parmeters ("+r" and "=r") passed to the hypercall.
+ *
+ * Each assembly block should use one of the HCALL_CLOBBERSx macros.  As a
+ * general rule, 'x' is the number of parameters passed to the assembly
+ * block *except* for r11.
+ *
+ * If you're not sure, just use the smallest value of 'x' that does not
+ * generate a compilation error.  Because these are static inline functions,
+ * the compiler will only check the clobber list for a function if you
+ * compile code that calls that function.
+ *
+ * r3 and r11 are not included in any clobbers list because they are always
+ * listed as output registers.
+ *
+ * XER, CTR, and LR are currently listed as clobbers because it's uncertain
+ * whether they will be clobbered.
+ *
+ * Note that r11 can be used as an output parameter.

+ *    HDMI supports only 8bpc or 12bpc, so clamp to 8bpc with dither for 10bpc

- * Rx theory of operation
- *
- * Driver allocates a circular buffer of Receive Buffer Descriptors (RBDs),
- * each of which point to Receive Buffers to be filled by the NIC.  These get
- * used not only for Rx frames, but for any command response or notification
- * from the NIC.  The driver and NIC manage the Rx buffers by means
- * of indexes into the circular buffer.
- *
- * Rx Queue Indexes
- * The host/firmware share two index registers for managing the Rx buffers.
- *
- * The READ index maps to the first position that the firmware may be writing
- * to -- the driver can read up to (but not including) this position and get
- * good data.
- * The READ index is managed by the firmware once the card is enabled.
- *
- * The WRITE index maps to the last position the driver has read from -- the
- * position preceding WRITE is the last slot the firmware can place a packet.
- *
- * The queue is empty (no good data) if WRITE = READ - 1, and is full if
- * WRITE = READ.
- *
- * During initialization, the host sets up the READ queue position to the first
- * INDEX position, and WRITE to the last (READ - 1 wrapped)
- *
- * When the firmware places a packet in a buffer, it will advance the READ index
- * and fire the RX interrupt.  The driver can then query the READ index and
- * process as many packets as possible, moving the WRITE index forward as it
- * resets the Rx queue buffers with new memory.
- *
- * The management in the driver is as follows:
- * + A list of pre-allocated SKBs is stored in iwl->rxq->rx_free.  When
- *   iwl->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
- *   to replenish the iwl->rxq->rx_free.
- * + In iwl_rx_replenish (scheduled) if 'processed' != 'read' then the

+/*
+ * Rx theory of operation
+ *
+ * Driver allocates a circular buffer of Receive Buffer Descriptors (RBDs),
+ * each of which point to Receive Buffers to be filled by the NIC.  These get
+ * used not only for Rx frames, but for any command response or notification
+ * from the NIC.  The driver and NIC manage the Rx buffers by means
+ * of indexes into the circular buffer.
+ *
+ * Rx Queue Indexes
+ * The host/firmware share two index registers for managing the Rx buffers.
+ *
+ * The READ index maps to the first position that the firmware may be writing
+ * to -- the driver can read up to (but not including) this position and get
+ * good data.
+ * The READ index is managed by the firmware once the card is enabled.
+ *
+ * The WRITE index maps to the last position the driver has read from -- the
+ * position preceding WRITE is the last slot the firmware can place a packet.
+ *
+ * The queue is empty (no good data) if WRITE = READ - 1, and is full if
+ * WRITE = READ.
+ *
+ * During initialization, the host sets up the READ queue position to the first
+ * INDEX position, and WRITE to the last (READ - 1 wrapped)
+ *
+ * When the firmware places a packet in a buffer, it will advance the READ index
+ * and fire the RX interrupt.  The driver can then query the READ index and
+ * process as many packets as possible, moving the WRITE index forward as it
+ * resets the Rx queue buffers with new memory.
+ *
+ * The management in the driver is as follows:
+ * + A list of pre-allocated SKBs is stored in iwl->rxq->rx_free.  When
+ *   iwl->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
+ *   to replenish the iwl->rxq->rx_free.
+ * + In iwl_rx_replenish (scheduled) if 'processed' != 'read' then the
+ *   iwl->rxq is replenished and the READ INDEX is updated (updating the
+ *   'processed' and 'read' driver indexes as well)
+ * + A received packet is processed and handed to the kernel network stack,

 Unless EASYCAP_DEBUG is defined during compilation it will not be possible
 to select a debug level at the time of module installation.
 
-If the parameter EASYCAP_IS_VIDEODEV_CLIENT is undefined during compilation
-the built module is entirely independent of the videodev module, and when
-the EasyCAP is physically plugged into a USB port the special files
-/dev/easycap0 and /dev/easysnd1 are created as video and sound sources
-respectively.
-
-If the parameter EASYCAP_IS_VIDEODEV_CLIENT is defined during compilation
-the built easycap module is configured to register with the videodev module,
-in which case the special files created when the EasyCAP is plugged in are
-/dev/video0 and /dev/easysnd0.
-
-During in-tree builds the following should should be defined whenever the
-parameter EASYCAP_IS_VIDEODEV_CLIENT is defined:
-
-EASYCAP_NEEDS_V4L2_DEVICE_H
-EASYCAP_NEEDS_V4L2_FOPS
-EASYCAP_NEEDS_UNLOCKED_IOCTL
-
-If the build is performed out-of-tree against older kernels the parameters
-to be defined depend on the kernel version in a way which will not be
-discussed here.

-config A2232
-	tristate "Commodore A2232 serial support (EXPERIMENTAL)"
-	depends on EXPERIMENTAL && ZORRO && BROKEN
-	---help---
-	  This option supports the 2232 7-port serial card shipped with the
-	  Amiga 2000 and other Zorro-bus machines, dating from 1989.  At
-	  a max of 19,200 bps, the ports are served by a 6551 ACIA UART chip
-	  each, plus a 8520 CIA, and a master 6502 CPU and buffer as well. The
-	  ports were connected with 8 pin DIN connectors on the card bracket,
-	  for which 8 pin to DB25 adapters were supplied. The card also had
-	  jumpers internally to toggle various pinning configurations.
-
-	  This driver can be built as a module; but then "generic_serial"
-	  will also be built as a module. This has to be loaded before
-	  "ser_a2232". If you want to do this, answer M here.
-
-config SX
-	tristate "Specialix SX (and SI) card support"
-	depends on SERIAL_NONSTANDARD && (PCI || EISA || ISA) && BROKEN
-	help
-	  This is a driver for the SX and SI multiport serial cards.
-	  Please read the file <file:Documentation/serial/sx.txt> for details.
-
-	  This driver can only be built as a module ( = code which can be
-	  inserted in and removed from the running kernel whenever you want).
-	  The module will be called sx. If you want to do that, say M here.
-
-config RIO
-	tristate "Specialix RIO system support"
-	depends on SERIAL_NONSTANDARD && BROKEN
-	help
-	  This is a driver for the Specialix RIO, a smart serial card which
-	  drives an outboard box that can support up to 128 ports.  Product
-	  information is at <http://www.perle.com/support/documentation.html#multiport>.
-	  There are both ISA and PCI versions.
-
-config RIO_OLDPCI
-	bool "Support really old RIO/PCI cards"
-	depends on RIO
-	help
-	  Older RIO PCI cards need some initialization-time configuration to
-	  determine the IRQ and some control addresses.  If you have a RIO and
-	  this doesn't seem to work, try setting this to Y.

-** HostUniqueNum is the unique number from the host card that this RTA

-** RtaUniqueNum is the unique number of the RTA concerned. It will be ZERO
-** if the slot in the table is unused. If it is the same as the HostUniqueNum
-** then this slot represents a host card.
-** Flags contains current boot/route state info
-** SysPort is a value in the range 0-504, being the number of the first tty
-** on this RTA. Each RTA supports 8 ports. The SysPort value must be modulo 8.
-** SysPort 0-127 correspond to /dev/ttyr001 to /dev/ttyr128, with minor
-** numbers 0-127. SysPort 128-255 correspond to /dev/ttyr129 to /dev/ttyr256,
-** again with minor numbers 0-127, and so on for SysPorts 256-383 and 384-511
-** ID will be in the range 0-16 for a `known' RTA. ID will be 0xFFFF for an
-** unused slot/unknown ID etc.
-** The Topology array contains the ID of the unit connected to each of the
-** four links on this unit. The entry will be 0xFFFF if NOTHING is connected
-** to the link, or will be 0xFF00 if an UNKNOWN unit is connected to the link.
-** The Name field is a null-terminated string, up to 31 characters, containing
-** the 'cute' name that the sysadmin/users know the RTA by. It is permissible
-** for this string to contain any character in the range \040 to \176 inclusive.
-** In particular, ctrl sequences and DEL (0x7F, \177) are not allowed. The
-** special character '%' IS allowable, and needs no special action.

-		 ** download has been assembled/compiled to expect to be
-		 ** loaded from 0x7FFF downwards. We have loaded it
-		 ** at some other address. The startup code goes into the small
-		 ** ram window at Sram2, in the last 8 bytes, which are really
-		 ** at addresses 0x7FF8-0x7FFF.
-		 **
-		 ** If the loadbase is, say, 0x7C00, then we need to branch to
-		 ** address 0x7BFE to run the host.bin startup code. We assemble
-		 ** this jump manually.
-		 **
-		 ** The two byte sequence 60 08 is loaded into memory at address
-		 ** 0x7FFE,F. This is a local branch to location 0x7FF8 (60 is nfix 0,
-		 ** which adds '0' to the .O register, complements .O, and then shifts
-		 ** it left by 4 bit positions, 08 is a jump .O+8 instruction. This will
-		 ** add 8 to .O (which was 0xFFF0), and will branch RELATIVE to the new
-		 ** location. Now, the branch starts from the value of .PC (or .IP or
-		 ** whatever the bloody register is called on this chip), and the .PC
-		 ** will be pointing to the location AFTER the branch, in this case
-		 ** .PC == 0x8000, so the branch will be to 0x8000+0xFFF8 = 0x7FF8.
-		 **
-		 ** A long branch is coded at 0x7FF8. This consists of loading a four
-		 ** byte offset into .O using nfix (as above) and pfix operators. The
-		 ** pfix operates in exactly the same way as the nfix operator, but
-		 ** without the complement operation. The offset, of course, must be
-		 ** relative to the address of the byte AFTER the branch instruction,
-		 ** which will be (urm) 0x7FFC, so, our final destination of the branch
-		 ** (loadbase-2), has to be reached from here. Imagine that the loadbase
-		 ** is 0x7C00 (which it is), then we will need to branch to 0x7BFE (which
-		 ** is the first byte of the initial two byte short local branch of the
-		 ** download code).
-		 **
-		 ** To code a jump from 0x7FFC (which is where the branch will start
-		 ** from) to 0x7BFE, we will need to branch 0xFC02 bytes (0x7FFC+0xFC02)=
-		 ** 0x7BFE.
-		 ** This will be coded as four bytes:
-		 ** 60 2C 20 02
-		 ** being nfix .O+0
-		 **        pfix .O+C
-		 **        pfix .O+0
-		 **        jump .O+2
-		 **
-		 ** The nfix operator is used, so that the startup code will be
-		 ** compatible with the whole Tp family. (lies, damn lies, it'll never
-		 ** work in a month of Sundays).
-		 **
-		 ** The nfix nyble is the 1s complement of the nyble value you

-** 
-** How to use this file:
-** 
-** To send a command down a rup, you need to allocate a command block, fill
-** in the packet information, fill in the command number, fill in the pre-
-** and post- functions and arguments, and then add the command block to the
-** queue of command blocks for the port in question. When the port is idle,
-** then the pre-function will be called. If this returns RIO_FAIL then the
-** command will be re-queued and tried again at a later date (probably in one
-** clock tick). If the pre-function returns NOT RIO_FAIL, then the command
-** packet will be queued on the RUP, and the txcontrol field set to the
-** command number. When the txcontrol field has changed from being the
-** command number, then the post-function will be called, with the argument
-** specified earlier, a pointer to the command block, and the value of
-** txcontrol.
-** 
-** To allocate a command block, call RIOGetCmdBlk(). This returns a pointer
-** to the command block structure allocated, or NULL if there aren't any.
-** The block will have been zeroed for you.
-** 
-** The structure has the following fields:
-** 
-** struct CmdBlk
-** {
-**	 struct CmdBlk *NextP;		  ** Pointer to next command block   **
-**	 struct PKT	 Packet;		** A packet, to copy to the rup	**
-**			int	 (*PreFuncP)();  ** The func to call to check if OK **
-**			int	 PreArg;		** The arg for the func			**
-**			int	 (*PostFuncP)(); ** The func to call when completed **
-**			int	 PostArg;	   ** The arg for the func			**
-** };
-** 
-** You need to fill in ALL fields EXCEPT NextP, which is used to link the
-** blocks together either on the free list or on the Rup list.
-** 
-** Packet is an actual packet structure to be filled in with the packet
-** information associated with the command. You need to fill in everything,
-** as the command processor doesn't process the command packet in any way.
-** 
-** The PreFuncP is called before the packet is enqueued on the host rup.
-** PreFuncP is called as (*PreFuncP)(PreArg, CmdBlkP);. PreFuncP must
-** return !RIO_FAIL to have the packet queued on the rup, and RIO_FAIL
-** if the packet is NOT to be queued.
-** 
-** The PostFuncP is called when the command has completed. It is called
-** as (*PostFuncP)(PostArg, CmdBlkP, txcontrol);. PostFuncP is not expected
-** to return a value. PostFuncP does NOT need to free the command block,
-** as this happens automatically after PostFuncP returns.
-** 
-** Once the command block has been filled in, it is attached to the correct
-** queue by calling RIOQueueCmdBlk( HostP, Rup, CmdBlkP ) where HostP is
-** a pointer to the struct Host, Rup is the NUMBER of the rup (NOT a pointer
-** to it!), and CmdBlkP is the pointer to the command block allocated using
-** RIOGetCmdBlk().

-** The Scam, based on email from jeremyr@bugs.specialix.co.uk....
-**
-** To send a command on a particular port, you put a packet with the
-** command bit set onto the port. The command bit is in the len field,
-** and gets ORed in with the actual byte count.
-**
-** When you send a packet with the command bit set the first
-** data byte (data[0]) is interpreted as the command to execute.
-** It also governs what data structure overlay should accompany the packet.
-** Commands are defined in cirrus/cirrus.h
-**
-** If you want the command to pre-emt data already on the queue for the
-** port, set the pre-emptive bit in conjunction with the command bit.
-** It is not defined what will happen if you set the preemptive bit
-** on a packet that is NOT a command.
-**
-** Pre-emptive commands should be queued at the head of the queue using
-** add_start(), whereas normal commands and data are enqueued using
-** add_end().
-**
-** Most commands do not use the remaining bytes in the data array. The
-** exceptions are OPEN MOPEN and CONFIG. (NB. As with the SI CONFIG and
-** OPEN are currently analogous). With these three commands the following
-** 11 data bytes are all used to pass config information such as baud rate etc.
-** The fields are also defined in cirrus.h. Some contain straightforward
-** information such as the transmit XON character. Two contain the transmit and
-** receive baud rates respectively. For most baud rates there is a direct
-** mapping between the rates defined in <sys/termio.h> and the byte in the
-** packet. There are additional (non UNIX-standard) rates defined in
-** /u/dos/rio/cirrus/h/brates.h.
-**
-** The rest of the data fields contain approximations to the Cirrus registers
-** that are used to program number of bits etc. Each registers bit fields is
-** defined in cirrus.h.
-** 
-** NB. Only use those bits that are defined as being driver specific
-** or common to the RTA and the driver.
-** 
-** All commands going from RTA->Host will be dealt with by the Host code - you
-** will never see them. As with the SI there will be three fields to look out
-** for in each phb (not yet defined - needs defining a.s.a.p).
-** 
-** modem_status	- current state of handshake pins.
-**
-** port_status	 - current port status - equivalent to hi_stat for SI, indicates
-** if port is IDLE_OPEN, IDLE_CLOSED etc.
-**
-** break_status	- bit X set if break has been received.
-** 
-** Happy hacking.

- * This driver is in EXPERIMENTAL state. That means I could not find
- * someone with five A2232 boards with 35 ports running at 19200 bps
- * at the same time and test the machine's behaviour.
- * However, I know that you can performance-tweak this driver (see
- * the source code).
- * One thing to consider is the time this driver consumes during the
- * Amiga's vertical blank interrupt. Everything that is to be done
- * _IS DONE_ when entering the vertical blank interrupt handler of
- * this driver.
- * However, it would be more sane to only do the job for only ONE card
- * instead of ALL cards at a time; or, more generally, to handle only
- * SOME ports instead of ALL ports at a time.
- * However, as long as no-one runs into problems I guess I shouldn't
- * change the driver as it runs fine for me :) .
- *
- * Version history of this file:
- * 0.4	Resolved licensing issues.
- * 0.3	Inclusion in the Linux/m68k tree, small fixes.
- * 0.2	Added documentation, minor typo fixes.
- * 0.1	Initial release.
- *
- * TO DO:
- * -	Handle incoming BREAK events. I guess "Stevens: Advanced
- *	Programming in the UNIX(R) Environment" is a good reference
- *	on what is to be done.
- * -	When installing as a module, don't simply 'printk' text, but
- *	send it to the TTY used by the user.
- *
- * THANKS TO:
- * -	Jukka Marin (65EC02 code).
- * -	The other NetBSD developers on whose A2232 driver I had a
- *	pretty close look. However, I didn't copy any code so it
- *	is okay to put my code under the GPL and include it into
- *	Linux.

- * Revision history:
- * Revision 1.33  2000/03/09 10:00:00  pvdl,wolff
- * - Fixed module and port counting
- * - Fixed signal handling
- * - Fixed an Ooops
- * 
- * Revision 1.32  2000/03/07 09:00:00  wolff,pvdl
- * - Fixed some sx_dprintk typos
- * - added detection for an invalid board/module configuration
- *
- * Revision 1.31  2000/03/06 12:00:00  wolff,pvdl
- * - Added support for EISA
- *
- * Revision 1.30  2000/01/21 17:43:06  wolff
- * - Added support for SX+
- *
- * Revision 1.26  1999/08/05 15:22:14  wolff
- * - Port to 2.3.x
- * - Reformatted to Linus' liking.
- *
- * Revision 1.25  1999/07/30 14:24:08  wolff
- * Had accidentally left "gs_debug" set to "-1" instead of "off" (=0).
- *
- * Revision 1.24  1999/07/28 09:41:52  wolff
- * - I noticed the remark about use-count straying in sx.txt. I checked
- *   sx_open, and found a few places where that could happen. I hope it's
- *   fixed now.
- *
- * Revision 1.23  1999/07/28 08:56:06  wolff
- * - Fixed crash when sx_firmware run twice.
- * - Added sx_slowpoll as a module parameter (I guess nobody really wanted
- *   to change it from the default... )
- * - Fixed a stupid editing problem I introduced in 1.22.
- * - Fixed dropping characters on a termios change.
- *
- * Revision 1.22  1999/07/26 21:01:43  wolff
- * Russell Brown noticed that I had overlooked 4 out of six modem control
- * signals in sx_getsignals. Ooops.
- *
- * Revision 1.21  1999/07/23 09:11:33  wolff
- * I forgot to free dynamically allocated memory when the driver is unloaded.
- *
- * Revision 1.20  1999/07/20 06:25:26  wolff
- * The "closing wait" wasn't honoured. Thanks to James Griffiths for
- * reporting this.
- *
- * Revision 1.19  1999/07/11 08:59:59  wolff
- * Fixed an oops in close, when an open was pending. Changed the memtest
- * a bit. Should also test the board in word-mode, however my card fails the
- * memtest then. I still have to figure out what is wrong...
- *
- * Revision 1.18  1999/06/10 09:38:42  wolff
- * Changed the format of the firmware revision from %04x to %x.%02x .
- *
- * Revision 1.17  1999/06/04 09:44:35  wolff
- * fixed problem: reference to pci stuff when config_pci was off...
- * Thanks to Jorge Novo for noticing this.
- *
- * Revision 1.16  1999/06/02 08:30:15  wolff
- * added/removed the workaround for the DCD bug in the Firmware.
- * A bit more debugging code to locate that...
- *
- * Revision 1.15  1999/06/01 11:35:30  wolff
- * when DCD is left low (floating?), on TA's the firmware first tells us
- * that DCD is high, but after a short while suddenly comes to the
- * conclusion that it is low. All this would be fine, if it weren't that
- * Unix requires us to send a "hangup" signal in that case. This usually
- * all happens BEFORE the program has had a chance to ioctl the device
- * into clocal mode..
- *
- * Revision 1.14  1999/05/25 11:18:59  wolff
- * Added PCI-fix.
- * Added checks for return code of sx_sendcommand.
- * Don't issue "reconfig" if port isn't open yet. (bit us on TA modules...)
- *
- * Revision 1.13  1999/04/29 15:18:01  wolff
- * Fixed an "oops" that showed on SuSE 6.0 systems.
- * Activate DTR again after stty 0.
- *
- * Revision 1.12  1999/04/29 07:49:52  wolff
- * Improved "stty 0" handling a bit. (used to change baud to 9600 assuming
- *     the connection would be dropped anyway. That is not always the case,
- *     and confuses people).
- * Told the card to always monitor the modem signals.
- * Added support for dynamic  gs_debug adjustments.
- * Now tells the rest of the system the number of ports.
- *
- * Revision 1.11  1999/04/24 11:11:30  wolff
- * Fixed two stupid typos in the memory test.
- *
- * Revision 1.10  1999/04/24 10:53:39  wolff
- * Added some of Christian's suggestions.
- * Fixed an HW_COOK_IN bug (ISIG was not in I_OTHER. We used to trust the
- * card to send the signal to the process.....)
- *
- * Revision 1.9  1999/04/23 07:26:38  wolff
- * Included Christian Lademann's 2.0 compile-warning fixes and interrupt
- *    assignment redesign.
- * Cleanup of some other stuff.
- *
- * Revision 1.8  1999/04/16 13:05:30  wolff
- * fixed a DCD change unnoticed bug.
- *
- * Revision 1.7  1999/04/14 22:19:51  wolff
- * Fixed typo that showed up in 2.0.x builds (get_user instead of Get_user!)
- *
- * Revision 1.6  1999/04/13 18:40:20  wolff
- * changed misc-minor to 161, as assigned by HPA.
- *
- * Revision 1.5  1999/04/13 15:12:25  wolff
- * Fixed use-count leak when "hangup" occurred.
- * Added workaround for a stupid-PCIBIOS bug.
- *
- *
- * Revision 1.4  1999/04/01 22:47:40  wolff
- * Fixed < 1M linux-2.0 problem.
- * (vremap isn't compatible with ioremap in that case)
- *
- * Revision 1.3  1999/03/31 13:45:45  wolff
- * Firmware loading is now done through a separate IOCTL.
- *
- * Revision 1.2  1999/03/28 12:22:29  wolff
- * rcs cleanup
- *
- * Revision 1.1  1999/03/28 12:10:34  wolff
- * Readying for release on 2.0.x (sorry David, 1.01 becomes 1.1 for RCS). 
- *
- * Revision 0.12  1999/03/28 09:20:10  wolff
- * Fixed problem in 0.11, continuing cleanup.
- *
- * Revision 0.11  1999/03/28 08:46:44  wolff
- * cleanup. Not good.
- *
- * Revision 0.10  1999/03/28 08:09:43  wolff
- * Fixed losing characters on close.
- *
- * Revision 0.9  1999/03/21 22:52:01  wolff
- * Ported back to 2.2.... (minor things)
- *
- * Revision 0.8  1999/03/21 22:40:33  wolff
- * Port to 2.0
- *
- * Revision 0.7  1999/03/21 19:06:34  wolff
- * Fixed hangup processing.
- *
- * Revision 0.6  1999/02/05 08:45:14  wolff
- * fixed real_raw problems. Inclusion into kernel imminent.
- *
- * Revision 0.5  1998/12/21 23:51:06  wolff
- * Snatched a nasty bug: sx_transmit_chars was getting re-entered, and it
- * shouldn't have. THATs why I want to have transmit interrupts even when
- * the buffer is empty.
- *
- * Revision 0.4  1998/12/17 09:34:46  wolff
- * PPP works. ioctl works. Basically works!
- *
- * Revision 0.3  1998/12/15 13:05:18  wolff
- * It works! Wow! Gotta start implementing IOCTL and stuff....
- *
- * Revision 0.2  1998/12/01 08:33:53  wolff
- * moved over to 2.1.130
- *
- * Revision 0.1  1998/11/03 21:23:51  wolff
- * Initial revision. Detects SX card.

-// This module is designed to provide a uniform method of sending commands to
-// the board through command packets. The difficulty is, some commands take
-// parameters, others do not. Furthermore, it is often useful to send several
-// commands to the same channel as part of the same packet. (See also i2pack.h.)
-//
-// This module is designed so that the caller should not be responsible for
-// remembering the exact syntax of each command, or at least so that the
-// compiler could check things somewhat. I'll explain as we go...
-//
-// First, a structure which can embody the syntax of each type of command.

-	UCHAR flags;    // Information about the command (see below)
-
-	// The command and its parameters, which may be of arbitrary length. Don't
-	// worry yet how the parameters will be initialized; macros later take care
-	// of it. Also, don't worry about the arbitrary length issue; this structure
-	// is never used to allocate space (see i2cmd.c).
-	UCHAR cmd[2];
-} cmdSyntax, *cmdSyntaxPtr;

-// Bit assignments for flags
-
-#define INL 1           // Set if suitable for inline commands
-#define BYP 2           // Set if suitable for bypass commands
-#define BTH (INL|BYP)   // suitable for either!
-#define END 4           // Set if this must be the last command in a block
-#define VIP 8           // Set if this command is special in some way and really
-						// should only be sent from the library-level and not
-						// directly from user-level
-#define VAR 0x10        // This command is of variable length!
-
-// Declarations for the global arrays used to bear the commands and their
-// arguments.
-//
-// Note: Since these are globals and the arguments might change, it is important
-// that the library routine COPY these into buffers from whence they would be
-// sent, rather than merely storing the pointers. In multi-threaded
-// environments, important that the copy should obtain before any context switch
-// is allowed. Also, for parameterized commands, DO NOT ISSUE THE SAME COMMAND
-// MORE THAN ONCE WITH THE SAME PARAMETERS in the same call.

-// Function:   ii2DelayIO(mseconds)
-// Parameters: mseconds - number of milliseconds to delay
-//
-// Returns:    Nothing
-//
-// Description:
-//
-// This routine delays for approximately mseconds milliseconds and is intended
-// to be called indirectly through i2Delay field in i2eBordStr. It is intended
-// for use where a clock-based function is impossible: for example, DOS drivers.
-//
-// This function uses the IN instruction to place bounds on the timing and
-// assumes that ii2Safe has been set. This is because I/O instructions are not
-// subject to caching and will therefore take a certain minimum time. To ensure
-// the delay is at least long enough on fast machines, it is based on some
-// fastest-case calculations.  On slower machines this may cause VERY long
-// delays. (3 x fastest case). In the fastest case, everything is cached except
-// the I/O instruction itself.
-//
-// Timing calculations:
-// The fastest bus speed for I/O operations is likely to be 10 MHz. The I/O
-// operation in question is a byte operation to an odd address. For 8-bit
-// operations, the architecture generally enforces two wait states. At 10 MHz, a
-// single cycle time is 100nS. A read operation at two wait states takes 6
-// cycles for a total time of 600nS. Therefore approximately 1666 iterations
-// would be required to generate a single millisecond delay. The worst
-// (reasonable) case would be an 8MHz system with no cacheing. In this case, the
-// I/O instruction would take 125nS x 6 cyles = 750 nS. More importantly, code
-// fetch of other instructions in the loop would take time (zero wait states,
-// however) and would be hard to estimate. This is minimized by using in-line
-// assembler for the in inner loop of IN instructions. This consists of just a
-// few bytes. So we'll guess about four code fetches per loop. Each code fetch
-// should take four cycles, so we have 125nS * 8 = 1000nS. Worst case then is
-// that what should have taken 1 mS takes instead 1666 * (1750) = 2.9 mS.
-//
-// So much for theoretical timings: results using 1666 value on some actual
-// machines:
-// IBM      286      6MHz     3.15 mS
-// Zenith   386      33MHz    2.45 mS
-// (brandX) 386      33MHz    1.90 mS  (has cache)
-// (brandY) 486      33MHz    2.35 mS
-// NCR      486      ??       1.65 mS (microchannel)
-//
-// For most machines, it is probably safe to scale this number back (remember,
-// for robust operation use an actual timed delay if possible), so we are using
-// a value of 1190. This yields 1.17 mS for the fastest machine in our sample,
-// 1.75 mS for typical 386 machines, and 2.25 mS the absolute slowest machine.
-//
-// 1/29/93:
-// The above timings are too slow. Actual cycle times might be faster. ISA cycle
-// times could approach 500 nS, and ...
-// The IBM model 77 being microchannel has no wait states for 8-bit reads and
-// seems to be accessing the I/O at 440 nS per access (from start of one to
-// start of next). This would imply we need 1000/.440 = 2272 iterations to
-// guarantee we are fast enough. In actual testing, we see that 2 * 1190 are in
-// fact enough. For diagnostics, we keep the level at 1190, but developers note
-// this needs tuning.

-HARDWARE DESCRIPTION:
-
-Introduction:
-
-The IntelliPort-II and IntelliPort-IIEX products occupy a block of eight (8)
-addresses in the host's I/O space.
-
-Some addresses are used to transfer data to/from the board, some to transfer
-so-called "mailbox" messages, and some to read bit-mapped status information.
-While all the products in the line are functionally similar, some use a 16-bit
-data path to transfer data while others use an 8-bit path. Also, the use of
-command /status/mailbox registers differs slightly between the II and IIEX
-branches of the family.
-
-The host determines what type of board it is dealing with by reading a string of
-sixteen characters from the board. These characters are always placed in the
-fifo by the board's local processor whenever the board is reset (either from
-power-on or under software control) and are known as the "Power-on Reset
-Message." In order that this message can be read from either type of board, the
-hardware registers used in reading this message are the same. Once this message
-has been read by the host, then it has the information required to operate.
-
-General Differences between boards:
-
-The greatest structural difference is between the -II and -IIEX families of
-product. The -II boards use the Am4701 dual 512x8 bidirectional fifo to support
-the data path, mailbox registers, and status registers. This chip contains some
-features which are not used in the IntelliPort-II products; a description of
-these is omitted here. Because of these many features, it contains many
-registers, too many to access directly within a small address space. They are
-accessed by first writing a value to a "pointer" register. This value selects
-the register to be accessed.  The next read or write to that address accesses
-the selected register rather than the pointer register.
-
-The -IIEX boards use a proprietary design similar to the Am4701 in function. But
-because of a simpler, more streamlined design it doesn't require so many
-registers. This means they can be accessed directly in single operations rather
-than through a pointer register.
-
-Besides these differences, there are differences in whether 8-bit or 16-bit
-transfers are used to move data to the board.
-
-The -II boards are capable only of 8-bit data transfers, while the -IIEX boards
-may be configured for either 8-bit or 16-bit data transfers. If the on-board DIP
-switch #8 is ON, and the card has been installed in a 16-bit slot, 16-bit
-transfers are supported (and will be expected by the standard loadware). The
-on-board firmware can determine the position of the switch, and whether the
-board is installed in a 16-bit slot; it supplies this information to the host as
-part of the power-up reset message.
-
-The configuration switch (#8) and slot selection do not directly configure the
-hardware. It is up to the on-board loadware and host-based drivers to act
-according to the selected options. That is, loadware and drivers could be
-written to perform 8-bit transfers regardless of the state of the DIP switch or
-slot (and in a diagnostic environment might well do so). Likewise, 16-bit
-transfers could be performed as long as the card is in a 16-bit slot.
-
-Note the slot selection and DIP switch selection are provided separately: a
-board running in 8-bit mode in a 16-bit slot has a greater range of possible
-interrupts to choose from; information of potential use to the host.
-
-All 8-bit data transfers are done in the same way, regardless of whether on a
--II board or a -IIEX board.
-
-The host must consider two things then: 1) whether a -II or -IIEX product is

-
-A further difference is that -II boards always have a 512-byte fifo operating in

-Rules:
-All data transfers are performed using the even i/o address. If byte-wide data
-transfers are being used, do INB/OUTB operations on the data port. If word-wide
-transfers are used, do INW/OUTW operations. In some circumstances (such as
-reading the power-up message) you will do INB from the data port, but in this
-case the MSB of each word read is lost. When accessing all other unreserved
-registers, use byte operations only.

-// Read: Status Register for IntelliPort-II or -IIEX
-// The presence of any bit set here will cause an interrupt to the host,

-// RESET & POWER-ON RESET MESSAGE
-/*------------------------------------------------------------------------------
-RESET:
-
-The IntelliPort-II and -IIEX boards are reset in three ways: Power-up, channel
-reset, and via a write to the reset register described above. For products using
-the ISA bus, these three sources of reset are equvalent. For MCA and EISA buses,
-the Power-up and channel reset sources cause additional hardware initialization
-which should only occur at system startup time.
-
-The third type of reset, called a "command reset", is done by writing any data
-to the FIFO_RESET address described above. This resets the on-board processor,
-FIFO, UARTS, and associated hardware.
-
-This passes control of the board to the bootstrap firmware, which performs a
-Power-On Self Test and which detects its current configuration. For example,
--IIEX products determine the size of FIFO which has been installed, and the
-number and type of expansion boxes attached.
-
-This and other information is then written to the FIFO in a 16-byte data block
-to be read by the host. This block is guaranteed to be present within two (2)
-seconds of having received the command reset. The firmware is now ready to
-receive loadware from the host.
-
-It is good practice to perform a command reset to the board explicitly as part
-of your software initialization.  This allows your code to properly restart from
-a soft boot. (Many systems do not issue channel reset on soft boot).
-
-Because of a hardware reset problem on some of the Cirrus Logic 1400's which are
-used on the product, it is recommended that you reset the board twice, separated
-by an approximately 50 milliseconds delay. (VERY approximately: probably ok to
-be off by a factor of five. The important point is that the first command reset
-in fact generates a reset pulse on the board. This pulse is guaranteed to last
-less than 10 milliseconds. The additional delay ensures the 1400 has had the
-chance to respond sufficiently to the first reset. Why not a longer delay? Much
-more than 50 milliseconds gets to be noticeable, but the board would still work.
-
-Once all 16 bytes of the Power-on Reset Message have been read, the bootstrap
-firmware is ready to receive loadware.
-
-Note on Power-on Reset Message format:
-The various fields have been designed with future expansion in view.
-Combinations of bitfields and values have been defined which define products
-which may not currently exist. This has been done to allow drivers to anticipate
-the possible introduction of products in a systematic fashion. This is not
-intended to suggest that each potential product is actually under consideration.

-/*
-Loadware may be sent to the board in two ways:
-1) It may be read from a (binary image) data file block by block as each block
-	is sent to the board. This is only possible when the initialization is
-	performed by code which can access your file system. This is most suitable
-	for diagnostics and appications which use the interface library directly.
-
-2) It may be hard-coded into your source by including a .h file (typically
-	supplied by Computone), which declares a data array and initializes every
-	element. This achieves the same result as if an entire loadware file had 
-	been read into the array.
-
-	This requires more data space in your program, but access to the file system
-	is not required. This method is more suited to driver code, which typically
-	is running at a level too low to access the file system directly.
-
-At present, loadware can only be generated at Computone.

-*
-*   PACKAGE:     Linux tty Device Driver for IntelliPort family of multiport
-*                serial I/O controllers.
-*
-*   DESCRIPTION: High-level interface code for the device driver. Uses the
-*                Extremely Low Level Interface Support (i2ellis.c). Provides an
-*                interface to the standard loadware, to support drivers or
-*                application code. (This is included source code, not a separate
-*                compilation module.)
-*
-*******************************************************************************/
-//------------------------------------------------------------------------------
-// Note on Strategy:
-// Once the board has been initialized, it will interrupt us when:
-// 1) It has something in the fifo for us to read (incoming data, flow control
-// packets, or whatever).
-// 2) It has stripped whatever we have sent last time in the FIFO (and
-// consequently is ready for more).
-//
-// Note also that the buffer sizes declared in i2lib.h are VERY SMALL. This
-// worsens performance considerably, but is done so that a great many channels
-// might use only a little memory.
-//------------------------------------------------------------------------------
-
-//------------------------------------------------------------------------------
-// Revision History:
-//
-// 0.00 -  4/16/91 --- First Draft
-// 0.01 -  4/29/91 --- 1st beta release
-// 0.02 -  6/14/91 --- Changes to allow small model compilation
-// 0.03 -  6/17/91 MAG Break reporting protected from interrupts routines with
-//                     in-line asm added for moving data to/from ring buffers,
-//                     replacing a variety of methods used previously.
-// 0.04 -  6/21/91 MAG Initial flow-control packets not queued until
-//                     i2_enable_interrupts time. Former versions would enqueue
-//                     them at i2_init_channel time, before we knew how many
-//                     channels were supposed to exist!
-// 0.05 - 10/12/91 MAG Major changes: works through the ellis.c routines now;
-//                     supports new 16-bit protocol and expandable boards.
-//      - 10/24/91 MAG Most changes in place and stable.
-// 0.06 -  2/20/92 MAG Format of CMD_HOTACK corrected: the command takes no
-//                     argument.
-// 0.07 -- 3/11/92 MAG Support added to store special packet types at interrupt
-//                     level (mostly responses to specific commands.)
-// 0.08 -- 3/30/92 MAG Support added for STAT_MODEM packet
-// 0.09 -- 6/24/93 MAG i2Link... needed to update number of boards BEFORE
-//                     turning on the interrupt.
-// 0.10 -- 6/25/93 MAG To avoid gruesome death from a bad board, we sanity check
-//                     some incoming.
-//
-// 1.1  - 12/25/96 AKM Linux version.
-//      - 10/09/98 DMC Revised Linux version.

-#include "i2pack.h"
-#include "i2cmd.h"

-// i2ChanStr -- Channel Structure:
-// Used to track per-channel information for the library routines using standard
-// loadware. Note also, a pointer to an array of these structures is patched
-// into the i2eBordStr (see i2ellis.h)
-//------------------------------------------------------------------------------
-//
-// If we make some limits on the maximum block sizes, we can avoid dealing with
-// buffer wrap. The wrapping of the buffer is based on where the start of the
-// packet is. Then there is always room for the packet contiguously.
-//
-// Maximum total length of an outgoing data or in-line command block. The limit
-// of 36 on data is quite arbitrary and based more on DOS memory limitations
-// than the board interface. However, for commands, the maximum packet length is
-// MAX_CMD_PACK_SIZE, because the field size for the count is only a few bits
-// (see I2PACK.H) in such packets. For data packets, the count field size is not
-// the limiting factor. As of this writing, MAX_OBUF_BLOCK < MAX_CMD_PACK_SIZE,
-// but be careful if wanting to modify either.
-//
-#define MAX_OBUF_BLOCK  36
-
-// Another note on maximum block sizes: we are buffering packets here. Data is
-// put into the buffer (if there is room) regardless of the credits from the
-// board. The board sends new credits whenever it has removed from his buffers a
-// number of characters equal to 80% of total buffer size. (Of course, the total
-// buffer size is what is reported when the very first set of flow control
-// status packets are received from the board. Therefore, to be robust, you must
-// always fill the board to at least 80% of the current credit limit, else you
-// might not give it enough to trigger a new report. These conditions are
-// obtained here so long as the maximum output block size is less than 20% the
-// size of the board's output buffers. This is true at present by "coincidence"
-// or "infernal knowledge": the board's output buffers are at least 700 bytes
-// long (20% = 140 bytes, at least). The 80% figure is "official", so the safest
-// strategy might be to trap the first flow control report and guarantee that
-// the effective maxObufBlock is the minimum of MAX_OBUF_BLOCK and 20% of first
-// reported buffer credit.

-// Information passes between the host and board through the FIFO in packets.
-// These have headers which indicate the type of packet. Because the fifo data
-// path may be 16-bits wide, the protocol is constrained such that each packet
-// is always padded to an even byte count. (The lower-level interface routines
-// -- i2ellis.c -- are designed to do this).
-//
-// The sender (be it host or board) must place some number of complete packets
-// in the fifo, then place a message in the mailbox that packets are available.
-// Placing such a message interrupts the "receiver" (be it board or host), who
-// reads the mailbox message and determines that there are incoming packets
-// ready. Since there are no partial packets, and the length of a packet is
-// given in the header, the remainder of the packet can be read without checking
-// for FIFO empty condition. The process is repeated, packet by packet, until
-// the incoming FIFO is empty. Then the receiver uses the outbound mailbox to
-// signal the board that it has read the data. Only then can the sender place
-// additional data in the fifo.
-//------------------------------------------------------------------------------
-//
-//------------------------------------------------
-// Definition of Packet Header Area
-//------------------------------------------------
-//
-// Caution: these only define header areas. In actual use the data runs off
-// beyond the end of these structures.
-//
-// Since these structures are based on sequences of bytes which go to the board,
-// there cannot be ANY padding between the elements.

- *		board 1 is assigned ttyF64  to ttyF127,

- * In PCI and EISA bus systems each range is mapped to card in

-
- * If the irqs are ALL set to 0,0,0,0 all boards operate in 
- * polled mode. For interrupt operation ISA boards require that the IRQ be

- * will enable interrupts using the BIOS configured irq for the board.

-// ToDo:
-//
-// Fix the immediate DSS_NOW problem.
-// Work over the channel stats return logic in ip2_ipl_ioctl so they
-//	make sense for all 256 possible channels and so the user space
-//	utilities will compile and work properly.
-//
-// Done:
-//
-// 1.2.14	/\/\|=mhw=|\/\/
-// Added bounds checking to ip2_ipl_ioctl to avoid potential terroristic acts.
-// Changed the definition of ip2trace to be more consistent with kernel style
-//	Thanks to Andreas Dilger <adilger@turbolabs.com> for these updates
-//
-// 1.2.13	/\/\|=mhw=|\/\/
-// DEVFS: Renamed ttf/{n} to tts/F{n} and cuf/{n} to cua/F{n} to conform
-//	to agreed devfs serial device naming convention.
-//
-// 1.2.12	/\/\|=mhw=|\/\/
-// Cleaned up some remove queue cut and paste errors
-//
-// 1.2.11	/\/\|=mhw=|\/\/
-// Clean up potential NULL pointer dereferences
-// Clean up devfs registration
-// Add kernel command line parsing for io and irq
-//	Compile defaults for io and irq are now set in ip2.c not ip2.h!
-// Reworked poll_only hack for explicit parameter setting
-//	You must now EXPLICITLY set poll_only = 1 or set all irqs to 0
-// Merged ip2_loadmain and old_ip2_init
-// Converted all instances of interruptible_sleep_on into queue calls
-//	Most of these had no race conditions but better to clean up now
-//
-// 1.2.10	/\/\|=mhw=|\/\/
-// Fixed the bottom half interrupt handler and enabled USE_IQI
-//	to split the interrupt handler into a formal top-half / bottom-half
-// Fixed timing window on high speed processors that queued messages to
-// 	the outbound mail fifo faster than the board could handle.
-//
-// 1.2.9
-// Four box EX was barfing on >128k kmalloc, made structure smaller by
-// reducing output buffer size
-//
-// 1.2.8
-// Device file system support (MHW)
-//
-// 1.2.7 
-// Fixed
-// Reload of ip2 without unloading ip2main hangs system on cat of /proc/modules
-//
-// 1.2.6
-//Fixes DCD problems
-//	DCD was not reported when CLOCAL was set on call to TIOCMGET
-//
-//Enhancements:
-//	TIOCMGET requests and waits for status return
-//	No DSS interrupts enabled except for DCD when needed
-//

- *	configured into a system must have their own separate io and memory
- *	addresses. No interrupt is required.

- * linux/drivers/char/serial167.c
- *
- * Driver for MVME166/7 board serial ports, which are via a CD2401.
- * Based very much on cyclades.c.
- *
- * MVME166/7 work by Richard Hirst [richard@sleepie.demon.co.uk]
- *
- * ==============================================================
- *
- * static char rcsid[] =
- * "$Revision: 1.36.1.4 $$Date: 1995/03/29 06:14:14 $";
- *
- *  linux/kernel/cyclades.c
- *
- * Maintained by Marcio Saito (cyclades@netcom.com) and
- * Randolph Bentson (bentson@grieg.seaslug.org)
- *
- * Much of the design and some of the code came from serial.c
- * which was copyright (C) 1991, 1992  Linus Torvalds.  It was
- * extensively rewritten by Theodore Ts'o, 8/16/92 -- 9/14/92,
- * and then fixed as suggested by Michael K. Johnson 12/12/92.
- *
- * This version does not support shared irq's.
- *
- * $Log: cyclades.c,v $
- * Revision 1.36.1.4  1995/03/29  06:14:14  bentson
- * disambiguate between Cyclom-16Y and Cyclom-32Ye;
- *
- * Changes:
- *
- * 200 lines of changes record removed - RGH 11-10-95, starting work on
- * converting this to drive serial ports on mvme166 (cd2401).
- *
- * Arnaldo Carvalho de Melo <acme@conectiva.com.br> - 2000/08/25
- * - get rid of verify_area
- * - use get_user to access memory from userspace in set_threshold,
- *   set_default_threshold and set_timeout
- * - don't use the panic function in serial167_init
- * - do resource release on failure on serial167_init
- * - include missing restore_flags in mvme167_serial_console_setup
- *
- * Kars de Jong <jongk@linux-m68k.org> - 2004/09/06
- * - replace bottom half handler with task queue handler

-/* The serial driver boot-time initialization code!
-    Hardware I/O ports are mapped to character special devices on a
-    first found, first allocated manner.  That is, this code searches
-    for Cyclom cards in the system.  As each is found, it is probed
-    to discover how many chips (and thus how many ports) are present.
-    These ports are mapped to the tty ports 64 and upward in monotonic
-    fashion.  If an 8-port card is replaced with a 16-port card, the
-    port mapping on a following card will shift.
-
-    This approach is different from what is used in the other serial
-    device driver because the Cyclom is more properly a multiplexer,
-    not just an aggregation of serial ports on one card.
-
-    If there are more cards with more ports than have been statically
-    allocated above, a warning is printed and the extra ports are ignored.

+    - See 'Debug Tips' on the project wiki.
+	- http://usbip.wiki.sourceforge.net/how-to-debug-usbip
     - usbip-host.ko must be bound to the target device.
-        - See /proc/bus/usb/devices and find "Driver=..." lines of the device.
+	- See /proc/bus/usb/devices and find "Driver=..." lines of the device.
     - Shutdown firewall.
-        - usbip now uses TCP port 3240.
+	- usbip now uses TCP port 3240.
     - Disable SELinux.
-    - If possible, compile your kernel with CONFIG_USB_DEBUG flag and try
-      again.
-    - Check your kernel and daemon messages.
-        ex. /var/log/{messages, kern.log, daemon.log, syslog}
+    - If possible, compile your kernel with CONFIG_USB_DEBUG flag and try again.
+    - Check the kernel and daemon messages.

-* Storage Design

-* DMA and LOWLEVEL modules have been designed.  The
-* storage module simple takes requests from the user, queues
-* the associated DMA requests for action, and then sends
-* the low level requests to the West Bridge firmware.

- * If set to TRUE, the basic numeric types are defined by the

- *
- * Description
- * The West Bridge API relies on some basic integral types to be
- * defined.  These types include uint8_t, int8_t, uint16_t,
- * int16_t, uint32_t, and int32_t.  If this macro is defined the
- * West Bridge API will define these types based on some basic
- * assumptions.  If this value is set and the West Bridge API is
- * used to set these types, the definition of these types must be
- * examined to insure that they are appropriate for the given
- * target architecture and compiler.
- *
- * Notes
- * It is preferred that if the basic platform development
- * environment defines these types that the CY_DEFINE_BASIC_TYPES
- * macro be undefined and the appropriate target system header file
- * be added to the file cyashaldef.h.

-/* Summary
-   This function finds the device object given the HAL tag
-
-   Description
-   The user associats a device TAG with each West Bridge device
-   created.  This tag is passed from the  API functions to and HAL
-   functions that need to ID a specific West Bridge device.  This
-   tag is also passed in from the user back into the API via
-   interrupt functions.  This function allows the API to find the
-   device structure associated with a given tag.
-
-   Notes
-   This function does a simple linear search for the device based
-   on the TAG.  This function is called each time an West Bridge
-   interrupt handler is called.  Therefore this works fine for a
-   small number of West Bridge devices (e.g. less than five).

-/*@@DMA Overview
-	This module manages the DMA operations to/from the West Bridge
-	device.  The DMA module maintains a DMA queue for each endpoint
-	so multiple DMA requests may be queued and they will complete
-	at some future time.
-
-	The DMA module must be started before it can be used.  It is
-	started by calling CyAsDmaStart().  This function initializes
-	all of the endpoint data structures.
-
-	In order to perform DMA on a particular endpoint, the endpoint
-	must be enabled by calling CyAsDmaEnableEndPoint(). In addition
-	to enabling or disabling the endpoint, this function also sets
-	the direction for a given endpoint.  Direction is given in USB
-	terms.  For P port to West Bridge traffic, the endpoint is a
-	CyAsDirectionIn endpoint.  For West Bridge to P port traffic,
-	the endpoint is a CyAsDirectionOut endpoint.
-
-	Once DMA is started and an endpoint is enabled, DMA requests
-	are issued by calling CyAsDmaQueueRequest().  This function
-	queue either a DMA read or DMA write request.  The callback
-	associated with the request is called once the request has been
-	fulfilled.

-/*@@Hardware Abstraction Layer (HAL)
-	Summary
-	This software module is supplied by the user of the West Bridge
-	API.  This module contains the software that is specific to the
-	hardware implementation or operating system of the client
-	system.
-
-	* Sleep Channels *
-	A sleep channel is a operating system object that provides that
-	capability for one thread or process to sleep while waiting on
-	the completion of some hardware event. The hardware event is
-	usually processed by a hardware interrupt and the interrupt
-	handler then wakes the thread or process that is sleeping.
-
-	A sleep channel provides the mechanism for this operation.  A
-	sleep channel is created and initialized during the API
-	initialization. When the API needs to wait for the hardware,
-	the API performs a SleepOn() operation on the sleep channel.
-	When hardware event occurs, an interrupt handler processes the
-	event and then performs a Wake() operation on the sleep channel
-	to wake the sleeping process or thread.
-
-	* DMA Model *
-	When the West Bridge API needs to transfer USB or storage data
-	to/from the West Bridge device, this is done using a "DMA"
-	operation.  In this context the term DMA is used loosely as the
-	West Bridge API does not really care if the data is transferred
-	using a burst read or write operation, or if the data is
-	transferred using programmed I/O operations.  When a "DMA"
-	operation is needed, the West Bridge API calls either
-	CyAsHalDmaSetupRead() or CyAsHalDmaSetupWrite() depending on the
-	direction of the data flow.  The West Bridge API expects the
-	"DMA" operation requested in the call to be completed and the
-	registered "DMA complete" callback to be called.
-
-	The West Bridge API looks at several factors to determine the
-	size of the "DMA" request to pass to the HAL layer.  First the
-	West Bridge API calls CyAsHalDmaMaxRequestSize() to determine
-	the maximum amount of data the HAL layer can accept for a "DMA"
-	operation on the requested endpoint.  The West Bridge API will
-	never exceed this value in a "DMA" request to the HAL layer.
-	The West Bridge API also sends the maximum amount of data the
-	West Bridge device can accept as part of the "DMA" request. If
-	the amount of data in the "DMA" request to the HAL layer
-	exceeds the amount of data the West Bridge device can accept,
-	it is expected that the HAL layer has the ability to break the
-	request into multiple operations.
-
-	If the HAL implementation requires the API to handle the size
-	of the "DMA" requests for one or more endpoints, the value
-	CY_AS_DMA_MAX_SIZE_HW_SIZE can be returned from the
-	CyAsHalDmaMaxRequestSize() call.  In this case, the API assumes
-	that the maximum size of each "DMA" request should be limited
-	to the maximum that can be accepted by the endpoint in question.
-
-	Notes
-	See the <install>/api/hal/scm_kernel/cyashalscm_kernel.c file
-	for an example of how the DMA request size can be managed by
-	the HAL implementation.
-
-	* Interrupt Handling *
-	The HAL implementation is required to handle interrupts arriving
-	from the West Bridge device, and call the appropriate handlers.
-	If the interrupt arriving is one of PLLLOCKINT, PMINT, MBINT or
-	MCUINT, the CyAsIntrServiceInterrupt API should be called to
-	service the interrupt.  If the interrupt arriving is DRQINT, the
-	HAL should identify the endpoint corresponding to which the DRQ
-	is being generated and perform the read/write transfer from the
-	West Bridge. See the <install>/api/hal/scm_kernel/
-	cyashalscm_kernel.c or <install>/api/hal/fpga/cyashalfpga.c
-	reference HAL implementations for examples.
-
-	The HAL implementation can choose to poll the West Bridge
-	interrupt status register instead of using interrupts.  In this
-	case, the polling has to be performed from a different thread/
-	task than the one running the APIs.  This is required because
-	there are API calls that block on the reception of data from the
-	West Bridge, which is delivered only through the interrupt
-	handlers.
-
-	* Required Functions *
-	This section defines the types and functions that must be
-	supplied in order to provide a complete HAL layer for the
-	West Bridge API.
-
-	Types that must be supplied:
-	* CyAsHalSleepChannel

-/* Summary
-   This is the type that represents a sleep channel
-
-   Description
-   A sleep channel is an operating system object that, when a
-   thread of control waits on the sleep channel, the thread
-   sleeps until another thread signals the sleep object. This
-   object is generally used when a high level API is called
-   and must wait for a response that is supplied in an interrupt
-   handler.  The thread calling the API is put into a sleep
-   state and when the reply arrives via the interrupt handler,
-   the interrupt handler wakes the sleeping thread to indicate
-   that the expect reply is available.

-/*@@Low Level Communications
-
-	Summary
-	The low level communications module is responsible for
-	communications between the West Bridge device and the P
-	port processor.  Communications is organized as a series
-	of requests and subsequent responses. For each request
-	there is a one and only one response. Requests may go
-	from the West Bridge device to the P port processor, or
-	from the P Port processor to the West Bridge device.
-
-	Description
-	Requests are issued across what is called a context. A
-	context is a single channel of communications from one
-	processor to another processor. There can be only a single
-	request outstanding on a context at a given time. Contexts
-	are used to identify subsystems that can only process a
-	single request at a time, but are independent of other
-	contexts in the system. For instance, there is a context
-	for communicating storage commands from the P port processor
-	to the West Bridge device.  There is also a context for
-	communicating USB commands from the P port processor to the
-	West Bridge device.
-
-	Requests and responses are identical with the exception of
-	the type bit in the request/response header.  If the type
-	bit is one, the packet is a request. If this bit is zero,
-	the packet is a response. Also encoded within the header of
-	the request/response is the code. The code is a command
-	code for a request, or a response code for a response.  For
-	a request, the code is a function of the context.  The code
-	0 has one meaning for the storage context and a different
-	meaning for the USB context.  The code is treated differently
-	in the response. If the code in the response is less than 16,
-	then the meaning of the response is global across all
-	contexts. If the response is greater than or equal to 16,
-	then the response is specific to the associated context.
-
-	Requests and responses are transferred between processors
-	through the mailbox registers.  It may take one or more cycles
-	to transmit a complete request or response.  The context is
-	encoded into each cycle of the transfer to insure the
-	receiving processor can route the data to the appropriate
-	context for processing. In this way, the traffic from multiple
-	contexts can be multiplexed into a single data stream through
-	the mailbox registers by the sending processor, and
-	demultiplexed from the mailbox registers by the receiving
-	processor.
-
-	* Firmware Assumptions *
-	The firmware assumes that mailbox contents will be consumed
-	immediately. Therefore for multi-cycle packets, the data is
-	sent in a tight polling loop from the firmware. This implies
-	that the data must be read from the mailbox register on the P
-	port side and processed immediately or performance of the
-	firmware will suffer. In order to insure this is the case,
-	the data from the mailboxes is read and stored immediately
-	in a per context buffer. This occurs until the entire packet
-	is received at which time the request packet is processed.
-	Since the protocol is designed to allow for only one
-	outstanding packet at a time, the firmware can never be in a
-	position of waiting on the mailbox registers while the P port
-	is processing a request.  Only after the response to the
-	previous request is sent will another request be sent.

-   sending periodic heartbeat messages to the processor.
-
-   Description
-   The West Bridge firmware can send heartbeat messages through the
-   mailbox register once every 500 ms. This message can be an overhead
-   as it causes regular Mailbox interrupts to happen, and is turned
-   off by default. The message can be used to test and verify that the
-   West Bridge firmware is alive. This API can be used to enable or
-   disable the heartbeat message.

-/*@@Media Transfer Protocol (MTP) Overview
-  Summary
-  The MTP API has been designed to allow MTP enabled West Bridge
-  devices to implement the MTP protocol while maintaining high
-  performance. West Bridge has the capability to enter into a
-  Turbo mode during a MTP SendObject or GetObject operation
-  enabling it to directly stream the data into or out of the
-  attached SD card with minimal involvement from the Processor.
-
-  Description
-  The MTP API is designed to act as a pass through implementation
-  of the MTP protocol for all operations. Each MTP transaction
-  received from the Host is passed through West Bridge and along
-  to the Processor. The Processor can then respond to the
-  transaction and pass data and/or responses back to the Host
-  through West Bridge.
-
-  The MTP API also allows for a high speed handling of MTP
-  SendObject and GetObject operations, referred to as Turbo MTP.
-  During a Turbo MTP operation West Bridge is responsible for
-  reading or writing the data for the MTP operation directly from
-  or to the SD card with minimal interaction from the Processor.
-  The is done by having the Processor transfer a Block Table
-  to West Bridge which contains the locations on the SD card that
-  need to be read or written. During the handling of a Turbo
-  Operation the Processor will then only periodically need to
-  send a new Block Table to West Bridge when the first is used up.
-  See the CyAsMTPInitSendObject and CyAsMTPInitGetObject functions
-  for more details.
-
-  In order to enable the MTP API you must first have a MTP enabled
-  West Bridge loaded with MTP firmware. You then must start the USB
-  and Storage APIs before starting the MTP API. See CyAsMTPStart
-  for more details.

-/*@@Endpoints
-  Summary
-  When using MTP firmware endpoints 2 and 6 are dedicated
-  to bulk MTP traffic and endpoint 1 is available for MTP
-  events.
-
-  Description
-  When using a MTP enabled West Brdige device endpoints 2 and
-  6 are made available for use to implement the MTP protocol.
-  These endpoints have a few special restrictions noted below
-  but otherwise the existing USB APIs can be used normally with
-  these endpoints.

-/*@@Storage APIs
-  Summary
-  This section documents the storage APIs supported by the
-  West Bridge API.
-
-  Description
-  The storage API is based on some specific concepts which
-  are referenced here.
-  * <LINK Storage API Overview>
-  * Addressing
-  * Ownership
-  * <LINK Asynchronous Versus Synchronous Operation>
-*/
-
-/*@@Storage API Overview
-  Summary
-  Storage devices are identified by media type. Each media
-  type is considered a  single logical device.
-
-  Description
-  Each media type has a consistent block size and consists
-  of a set of logical blocks numbered from 0 to N - 1 where
-  N is the size of the
-  media type in blocks. The mass storage APIs defined below
-  provide the
-  capability to query for devices that are present, and
-  read/write data to/from
-  these devices.
-*/
-
-/*@@Addressing
-  Summary
-  Blocks within a storage device are address by a hierarchal
-  block address.  This
-  address consists of the bus number, physical device,
-   logical unit, and finally
-  block address.
-
-  Description
-  While currently only a single device of each media type
-  is supported, the address
-  space reserves space in the future for multiple devices
-  of each type.  Therefore
-  the second element of the address is the specific device
-  being addressed within
-  a given device type.  For this release of the software,
-  this value will always be
-  zero to address the first device.
-
-  The third element of the address is the logical unit.
-  A device being managed
-  by West Bridge can be partitioned into multiple logical
-  units.  This partition
-  information is stored on each device itself.  Currently,
-  one of the storage devices
-  managed by West Bridge can be partitioned into two
-  logical units.
-
-  Finally a logical block address is given within the
-  logical unit to address an
-  individual block.
-*/
-
-/*@@Ownership
-  Summary
-  While West Bridge supports concurrent block level
-  operations from both the USB port and
-  the processor port, this is not desirable in most
-  situations as the file system
-  contained on the storage media cannot be accessed
-  concurrently.  To insure access
-  by only one of USB and the processor, the West Bridge
-  API provides for ownership of storage
-  devices based on media type.
-
-  Description
-  The processor requests ownership of a given media type
-  by calling CyAsStorageClaim().
-  The firmware in West Bridge releases control of the
-  media and signals the processor through
-  the event callback registered with
-  CyAsStorageRegisterCallback().  The specific event is
-  the CyAsStorageProcessor. The processor can later
-  release the media via a call to
-  CyAsStorageRelease().  This call is immediate and
-  no callback is required.
-
-  If the processor has claimed storage and the USB port
-  is connected, West Bridge will need to
-  claim the storage to manage the mass storage device.
-  West Bridge requests the storage through
-  the event callback registered with
-  CyAsStorageRegisterCallback().  The specific event is
-  CyAsStorageAntioch and is named as such to reflect
-  the USB view of storage.  This callback
-  is a request for the processor to release storage.
-  The storage is not actually released
-  until the processor calls CyAsStorageRelease().
-
-  Note that the CyAsStorageAntioch is only sent when the
-  USB storage device is enumerated and
-  NOT at every USB operation.  The ownership of a given
-  storage media type is assumed to belong
-  to the processor until the USB connection is established.
-  At that point, the storage ownership
-  is transferred to West Bridge.  After the USB connection
-  is broken, ownership can be transferred
-  back to the processor.
-*/
-
-/*@@Asynchronous Versus Synchronous Operation
-  Summary
-  When read or write operations are performed to the
-  storage devices, these operations may be
-  synchronous or asynchronous.  A synchronous operation
-  is an operation where the read or write
-  operation is requested and the function does not return
-  until the operation is complete.  This
-  type of function is the easiest to use but does not
-  provide for optimal usage of the P port processor time.
-
-  Description
-  An asynchronous operation is one where the function returns
-  as soon as the request is started.
-  The specific read and write request will complete at some
-  time in the future and the P port
-  processor will be notified via a callback function.  While
-  asynchronous functions provide for
-  much better usage of the CPU, these function have more
-  stringent requirements for use.  First,
-  any buffer use for data transfer must be valid from the
-  function call to request the operation
-  through when the callback function is called.  This basically
-  implies that stack based buffers
-  are not acceptable for asynchronous calls.  Second, error
-  handling must be deferred until the
-  callback function is called indicating any kind of error
-  that may have occurred.
-*/
-
-/*@@Partitioning
-  Summary
-  West Bridge API and firmware support the creation of up to
-  two logical partitions on one
-  of the storage devices that are managed by West Bridge.  The
-  partitions are managed through
-  the CyAsStorageCreatePPartition and CyAsStorageRemovePPartition
-  APIs.
-
-  Description
-  The CyAsStorageCreatePPartition API is used to divide the total
-  storage on a storage
-  device into two logical units or partitions.  Since the partition
-  information is stored
-  on the storage device in a custom format, partitions should
-  only be created on fixed
-  storage devices (i.e., no removable SD/MMC cards).  Any data
-  stored on the device
-  before the creation of the partition, is liable to be lost when
-  a partition is created.
-
-  The CyAsStorageRemovePPartition API is used to remove the
-  stored partition information,
-  so that all of the device's capacity is treated as a single
-  partition again.
-
-  When a storage device with two partitions (units) is being
-  enumerated as a mass storage
-  device through the West Bridge, it is possible to select the
-  partitions to be made
-  visible to the USB host.  This is done through the
-  CyAsUsbSelectMSPartitions API.

-   This constants indicates a raw device access to the read/write
-   functions
-
-   Description
-   When performing reading and writing operations on the

-   to West Bridge, there are cases where writes need to
-   happen to raw devices, versus
-   the units contained within a device.  This is
-   specifically required to manage
-   the partitions within physical devices.  This constant
-   is used in calls to
-   CyAsStorageRead(), CyAsStorageReadAsync(),

-   CyAsStorageWriteAsync(), to indicate that the raw

-   accessed and not any specific unit on the device.

-/*@@Enumeration Model
-  Summary
-  The USB enumeration process is the process of communicating
-  to the USB host information
-  about the capabilities of the connected device.  This
-  process is completed by servicing
-  requests for various types of descriptors.  In the software
-  APIs described below, this
-  process is controlled in one of two ways.
-
-  Description
-  There are advantages to either type of enumeration
-  and this is why both models are supported.
-  P Port processor based enumeraton gives the P port
-  processor maximum control and flexibility
-  for providing USB configuration information.  However,
-  this does require (near) real time data
-  responses from the P port processor during the enumeration
-  process.  West Bridge based enumeration
-  requires no real time information from the P port processor,
-  ensuring the fastest possible
-  enumeration times.
-
-  * P Port Based Enumeration *
-  The first method for handling USB enumeration is for the
-  processor client to handle all
-  endpoint zero requests for descriptors.  This mode is
-  configured by indicating to the API
-  that the processor wants to handle all endpoint zero
-  requests. This is done by setting
-  bit 0 in the end_point_mask to a 1.  The processor uses
-  CyAsUsbReadDataAsync() to read the request and
-  CyAsUsbWriteDataAsync() to write the response.
-
-  * West Bridge Based Enumeration *
-  The second method for handling USB enumeration is the
-  configuration information method.
-  Before enabling a connection from the West Bridge device
-  to the USB connector, the P Port
-  processor sends information about the USB configuration to
-  West Bridge through the configuration
-  APIs.  This information is stored within the West Bridge
-  device.  When a USB cable is attached,
-  the West Bridge device then handles all descriptor requests
-  based on the stored information.
-  Note that this method of enumeration only supports a single
-  USB configuration.
-
-  In either model of enumeration, the processor client is
-  responsible for ensuring that
-  the system meets USB Chapter 9 compliance requirements. This
-  can be done by providing spec
-  compliant descriptors, and handling any setup packets that
-  are sent to the client
-  appropriately.
-
-  Mass storage class compliance will be ensured by the West
-  Bridge firmware when the mass
-  storage functionality is enabled.
-*/
-
-/*@@Endpoint Configuration
-  Summary
-  The West Bridge device has one 64-byte control endpoint, one
-  64-byte low bandwidth endpoint, four bulk
-  endpoints dedicated for mass storage usage, and up to ten
-  bulk/interrupt/isochronous
-  endpoints that can be used for USB-to-Processor communication.
-
-  Description
-  The four storage endpoints (Endpoints 2, 4, 6 and 8) are
-  reserved for accessing storage
-  devices attached to West Bridge and are not available for use
-  by the processor.  These are
-  used implicitly when using the storage API to read/write to
-  the storage media.
-
-  Endpoint 0 is the standard USB control pipe used for all
-  enumeration activity.  Though
-  the endpoint buffer is not directly accessible from the
-  processor, read/write activity
-  can be performed on this endpoint through the API layers.
-  This endpoint is always
-  configured as a bi-directional control endpoint.
-
-  Endpoint 1 is a 64-byte endpoint that can be used for low
-  bandwidth bulk/interrupt
-  activity.  The physical buffer is not accessible from the
-  processor, but can be read/written
-  through the API.  As the data coming to this endpoint is
-  being handled through the
-  software layers, there can be loss of data if a read call
-  is not waiting when an OUT
-  packet arrives.
-
-  Endpoints 3, 5, 7, 9, 10, 11, 12, 13, 14 and 15 are ten
-  configurable endpoints
-  mapped to parts of a total 4 KB FIFO buffer space on the
-  West Bridge device.  This 4 KB
-  physical buffer space is divided into up to four endpoints
-  called PEP1, PEP2, PEP3 and PEP4
-  in this software document.  There are multiple configurations
-  in which this buffer space
-  can be used, and the size and number of buffers available to
-  each physical endpoint
-  vary between these configurations.  See the West Bridge PDD
-  for details on the buffer
-  orientation corresponding to each configuration.
-
-  * Note *
-  PEPs 1, 2, 3 and 4 are called Physical EP 3, 5, 7 and 9 in the
-  West Bridge PDD.  The
-  sequential number scheme is used in the software to disambiguate
-  these from the logical
-  endpoint numbers, and also for convenience of array indexing.

-   This data structure is the data passed via the evdata paramater
-   on a usb event callback for the inquiry request.
-
-   Description
-   When a SCSI inquiry request arrives via the USB connection and
-   the P Port has asked
-   to receive inquiry requests, this request is forwarded to the
-   client via the USB
-   callback.  This callback is called twice, once before the
-   inquiry data is forwarded
-   to the host (CyAsEventUsbInquiryBefore) and once after the
-   inquiry has been sent to the
-   USB host (CyAsEventUsbInquiryAfter).  The evdata parameter
-   is a pointer to this data
-   structure.
-
-   *CyAsEventUsbInquiryBefore*
-   If the client just wishes to see the inquiry request and
-   associated data, then a simple
-   return from the callback will forward the inquiry response
-   to the USB host.  If the
-   client wishes to change the data returned to the USB host,
-   the updated parameter must
-   be set to CyTrue and the memory area address by the data
-   parameter should be updated.
-   The data pointer can be changed to point to a new memory
-   area and the length field
-   changed to change the amount of data returned from the
-   inquiry request.  Note that the
-   data area pointed to by the data parameter must remain
-   valid and the contents must
-   remain consistent until after the CyAsEventUsbInquiryAfter
-   event has occurred.  THE LENGTH
-   MUST BE LESS THAN 192 BYTES OR THE CUSTOM INQUIRY RESPONSE
-   WILL NOT BE RETURNED.  If the
-   length is too long, the default inquiry response will be
-   returned.
-
-   *CyAsEventUsbInquiryAfter*
-   If the client needs to free any data, this event signals that
-   the data associated with the inquiry is no longer needed.

-   The initialization process involves calling CyAsUsbSetEnumConfig()
-   and CyAsUsbSetEndPointConfig(). These
-   functions do not actually send the configuration information to
-   the West Bridge device.  Instead, these
-   functions store away the configuration information and this
-   CyAsUsbCommitConfig() actually finds the
-   best hardware configuration based on the requested endpoint
-   configuration and sends this optimal
-   confiuration down to the West Bridge device.
-
-   * Valid In Asynchronous Callback: YES (if cb supplied)
-   * Nestable: YES
-
-   Returns
-   * CY_AS_ERROR_SUCCESS - a configuration was found and sent
-   *	to West Bridge

+ *	size must also be initialized.  This is modified on success.
+ *
+ * By choosing an endpoint to use with the specified descriptor, this
+ * routine simplifies writing gadget drivers that work with multiple
+ * USB device controllers.  The endpoint would be passed later to
+ * usb_ep_enable(), along with some descriptor.
+ *
+ * That second descriptor won't always be the same as the first one.
+ * For example, isochronous endpoints can be autoconfigured for high
+ * bandwidth, and then used in several lower bandwidth altsettings.
+ * Also, high and full speed descriptors will be different.
+ *
+ * Be sure to examine and test the results of autoconfiguration on your
+ * hardware.  This code may not make the best choices about how to use the
+ * USB controller, and it can't know all the restrictions that may apply.
+ * Some combinations of driver and hardware won't be able to autoconfigure.
+ *
+ * On success, this returns an un-claimed usb_ep, and modifies the endpoint
+ * descriptor bEndpointAddress.  For bulk endpoints, the wMaxPacket value
+ * is initialized as if the endpoint were used at full speed.  To prevent
+ * the endpoint from being returned by a later autoconfig call, claim it

+	  Memory hotplug support for Xen balloon driver allows expanding memory
+	  available for the system above limit declared at system startup.
+	  It is very useful on critical systems which require long
+	  run without rebooting.
+
+	  Memory could be hotplugged in following steps:
+
+	    1) dom0: xl mem-max <domU> <maxmem>
+	       where <maxmem> is >= requested memory size,
+
+	    2) dom0: xl mem-set <domU> <memory>
+	       where <memory> is requested memory size; alternatively memory
+	       could be added by writing proper value to
+	       /sys/devices/system/xen_memory/xen_memory0/target or
+	       /sys/devices/system/xen_memory/xen_memory0/target_kb on dumU,
+
+	    3) domU: for i in /sys/devices/system/memory/memory*/state; do \
+	               [ "`cat "$i"`" = offline ] && echo online > "$i"; done
+
+	  Memory could be onlined automatically on domU by adding following line to udev rules:
+
+	  SUBSYSTEM=="memory", ACTION=="add", RUN+="/bin/sh -c '[ -f /sys$devpath/state ] && echo online > /sys$devpath/state'"
+
+	  In that case step 3 should be omitted.

+#  After doing a make localyesconfig, your kernel configuration may
+#  not be the most useful minimum configuration. Having a true minimum
+#  config that you can use against other configs is very useful if
+#  someone else has a config that breaks on your code. By only forcing
+#  those configurations that are truly required to boot your machine
+#  will give you less of a chance that one of your set configurations
+#  will make the bug go away. This will give you a better chance to
+#  be able to reproduce the reported bug matching the broken config.
+#
+#  Note, this does take some time, and may require you to run the
+#  test over night, or perhaps over the weekend. But it also allows
+#  you to interrupt it, and gives you the current minimum config
+#  that was found till that time.
+#
+#  Note, this test automatically assumes a BUILD_TYPE of oldconfig
+#  and its test type acts like boot.
+#  TODO: add a test version that makes the config do more than just
+#   boot, like having network access.
+#
+#  To save time, the test does not just grab any option and test
+#  it. The Kconfig files are examined to determine the dependencies
+#  of the configs. If a config is chosen that depends on another
+#  config, that config will be checked first. By checking the
+#  parents first, we can eliminate whole groups of configs that
+#  may have been enabled.
+#
+#  For example, if a USB device config is chosen and depends on CONFIG_USB,
+#  the CONFIG_USB will be tested before the device. If CONFIG_USB is
+#  found not to be needed, it, as well as all configs that depend on
+#  it, will be disabled and removed from the current min_config.
+#
+#  OUTPUT_MIN_CONFIG is the path and filename of the file that will
+#   be created from the MIN_CONFIG. If you interrupt the test, set
+#   this file as your new min config, and use it to continue the test.
+#   This file does not need to exist on start of test.
+#   This file is not created until a config is found that can be removed.
+#   If this file exists, you will be prompted if you want to use it
+#   as the min_config (overriding MIN_CONFIG) if START_MIN_CONFIG
+#   is not defined.
+#   (required field)
+#
+#  START_MIN_CONFIG is the config to use to start the test with.
+#   you can set this as the same OUTPUT_MIN_CONFIG, but if you do
+#   the OUTPUT_MIN_CONFIG file must exist.
+#   (default MIN_CONFIG)
+#
+#  IGNORE_CONFIG is used to specify a config file that has configs that
+#   you already know must be set. Configs are written here that have
+#   been tested and proved to be required. It is best to define this
+#   file if you intend on interrupting the test and running it where
+#   it left off. New configs that it finds will be written to this file
+#   and will not be tested again in later runs.
