-config VT
-	bool "Virtual terminal" if EMBEDDED
-	depends on !S390
-	select INPUT
-	default y
-	---help---
-	  If you say Y here, you will get support for terminal devices with
-	  display and keyboard devices. These are called "virtual" because you
-	  can run several virtual terminals (also called virtual consoles) on
-	  one physical terminal. This is rather useful, for example one
-	  virtual terminal can collect system messages and warnings, another
-	  one can be used for a text-mode user session, and a third could run
-	  an X session, all in parallel. Switching between virtual terminals
-	  is done with certain key combinations, usually Alt-<function key>.
-
-	  The setterm command ("man setterm") can be used to change the
-	  properties (such as colors or beeping) of a virtual terminal. The
-	  man page console_codes(4) ("man console_codes") contains the special
-	  character sequences that can be used to change those properties
-	  directly. The fonts used on virtual terminals can be changed with
-	  the setfont ("man setfont") command and the key bindings are defined
-	  with the loadkeys ("man loadkeys") command.
-
-	  You need at least one virtual terminal device in order to make use
-	  of your keyboard and monitor. Therefore, only people configuring an
-	  embedded system would want to say N here in order to save some
-	  memory; the only way to log into such a system is then via a serial
-	  or network connection.

-config VT_CONSOLE
-	bool "Support for console on virtual terminal" if EMBEDDED
-	depends on VT
-	default y
-	---help---
-	  The system console is the device which receives all kernel messages
-	  and warnings and which allows logins in single user mode. If you
-	  answer Y here, a virtual terminal (the device used to interact with
-	  a physical terminal) can be used as system console. This is the most
-	  common mode of operations, so you should say Y here unless you want
-	  the kernel messages be output only to a serial port (in which case
-	  you should say Y to "Console on serial port", below).
-
-	  If you do say Y here, by default the currently visible virtual
-	  terminal (/dev/tty0) will be used as system console. You can change
-	  that with a kernel command line option such as "console=tty3" which
-	  would use the third virtual terminal as system console. (Try "man
-	  bootparam" or see the documentation of your boot loader (lilo or
-	  loadlin) about how to pass options to the kernel at boot time.)

-       ---help---
-         The virtual terminal is the device that interacts with the physical
-         terminal through console drivers. On these systems, at least one
-         console driver is loaded. In other configurations, additional console
-         drivers may be enabled, such as the framebuffer console. If more than
-         1 console driver is enabled, setting this to 'y' will allow you to
-         select the console driver that will serve as the backend for the
-         virtual terminals.

-    Hardware I/O ports are mapped to character special devices on a

-    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 32 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.

- *
- * Author(s) :  Ryan S. Arnold <rsa@us.ibm.com>
- *
- * This is the device driver for the IBM Hypervisor Virtual Console Server,
- * "hvcs".  The IBM hvcs provides a tty driver interface to allow Linux
- * user space applications access to the system consoles of logically
- * partitioned operating systems, e.g. Linux, running on the same partitioned
- * Power5 ppc64 system.  Physical hardware consoles per partition are not
- * practical on this hardware so system consoles are accessed by this driver
- * using inter-partition firmware interfaces to virtual terminal devices.
- *
- * A vty is known to the HMC as a "virtual serial server adapter".  It is a
- * virtual terminal device that is created by firmware upon partition creation
- * to act as a partitioned OS's console device.
- *
- * Firmware dynamically (via hotplug) exposes vty-servers to a running ppc64
- * Linux system upon their creation by the HMC or their exposure during boot.
- * The non-user interactive backend of this driver is implemented as a vio
- * device driver so that it can receive notification of vty-server lifetimes
- * after it registers with the vio bus to handle vty-server probe and remove
- * callbacks.
- *
- * Many vty-servers can be configured to connect to one vty, but a vty can
- * only be actively connected to by a single vty-server, in any manner, at one
- * time.  If the HMC is currently hosting the console for a target Linux
- * partition; attempts to open the tty device to the partition's console using
- * the hvcs on any partition will return -EBUSY with every open attempt until
- * the HMC frees the connection between its vty-server and the desired
- * partition's vty device.  Conversely, a vty-server may only be connected to
- * a single vty at one time even though it may have several configured vty
- * partner possibilities.
- *
- * Firmware does not provide notification of vty partner changes to this
- * driver.  This means that an HMC Super Admin may add or remove partner vtys
- * from a vty-server's partner list but the changes will not be signaled to
- * the vty-server.  Firmware only notifies the driver when a vty-server is
- * added or removed from the system.  To compensate for this deficiency, this
- * driver implements a sysfs update attribute which provides a method for
- * rescanning partner information upon a user's request.
- *
- * Each vty-server, prior to being exposed to this driver is reference counted
- * using the 2.6 Linux kernel kref construct.
- *
- * For direction on installation and usage of this driver please reference
- * Documentation/powerpc/hvcs.txt.

- * 1.3.0 -> 1.3.1 In hvcs_open memset(..,0x00,..) instead of memset(..,0x3F,00).
- * Removed braces around single statements following conditionals.  Removed '=
- * 0' after static int declarations since these default to zero.  Removed
- * list_for_each_safe() and replaced with list_for_each_entry() in
- * hvcs_get_by_index().  The 'safe' version is un-needed now that the driver is
- * using spinlocks.  Changed spin_lock_irqsave() to spin_lock() when locking
- * hvcs_structs_lock and hvcs_pi_lock since these are not touched in an int
- * handler.  Initialized hvcs_structs_lock and hvcs_pi_lock to
- * SPIN_LOCK_UNLOCKED at declaration time rather than in hvcs_module_init().
- * Added spin_lock around list_del() in destroy_hvcs_struct() to protect the
- * list traversals from a deletion.  Removed '= NULL' from pointer declaration
- * statements since they are initialized NULL by default.  Removed wmb()
- * instances from hvcs_try_write().  They probably aren't needed with locking in
- * place.  Added check and cleanup for hvcs_pi_buff = kmalloc() in
- * hvcs_module_init().  Exposed hvcs_struct.index via a sysfs attribute so that
- * the coupling between /dev/hvcs* and a vty-server can be automatically
- * determined.  Moved kobject_put() in hvcs_open outside of the
- * spin_unlock_irqrestore().
- *
- * 1.3.1 -> 1.3.2 Changed method for determining hvcs_struct->index and had it
- * align with how the tty layer always assigns the lowest index available.  This
- * change resulted in a list of ints that denotes which indexes are available.
- * Device additions and removals use the new hvcs_get_index() and
- * hvcs_return_index() helper functions.  The list is created with
- * hvsc_alloc_index_list() and it is destroyed with hvcs_free_index_list().
- * Without these fixes hotplug vty-server adapter support goes crazy with this
- * driver if the user removes a vty-server adapter.  Moved free_irq() outside of
- * the hvcs_final_close() function in order to get it out of the spinlock.
- * Rearranged hvcs_close().  Cleaned up some printks and did some housekeeping
- * on the changelog.  Removed local CLC_LENGTH and used HVCS_CLC_LENGTH from
- * arch/powerepc/include/asm/hvcserver.h
- *
- * 1.3.2 -> 1.3.3 Replaced yield() in hvcs_close() with tty_wait_until_sent() to
- * prevent possible lockup with realtime scheduling as similarily pointed out by
- * akpm in hvc_console.  Changed resulted in the removal of hvcs_final_close()
- * to reorder cleanup operations and prevent discarding of pending data during
- * an hvcs_close().  Removed spinlock protection of hvcs_struct data members in
- * hvcs_write_room() and hvcs_chars_in_buffer() because they aren't needed.

+	  as the host has, rather than the small amount the UML gets from its
+	  own drivers.  It registers itself as a standard hardware random number
+	  generator, major 10, minor 183, and the canonical device name is
+	  /dev/hwrng.
+	  The way to make use of this is to install the rng-tools package
+	  (check your distro, or download from
+	  http://sourceforge.net/projects/gkernel/).  rngd periodically reads
+	  /dev/hwrng and injects the entropy into /dev/random.

-// 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];

-#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
-being used, and 2) whether an 8-bit or 16-bit data path is used.
-
-A further difference is that -II boards always have a 512-byte fifo operating in
-each direction. -IIEX boards may use fifos of varying size; this size is
-reported as part of the power-up message.
-
-I/O Map Of IntelliPort-II and IntelliPort-IIEX boards:
-(Relative to the chosen base address)
-
-Addr  R/W      IntelliPort-II    IntelliPort-IIEX
-----  ---      --------------    ----------------
-0     R/W      Data Port (byte)  Data Port (byte or word)
-1     R/W      (Not used)        (MSB of word-wide data written to Data Port)
-2     R        Status Register   Status Register
-2     W        Pointer Register  Interrupt Mask Register
-3     R/W      (Not used)        Mailbox Registers (6 bits: 11111100)
-4,5   --       Reserved for future products
-6     --       Reserved for future products
-7     R        Guaranteed to have no effect
-7     W        Hardware reset of board.
-
-
-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.

-// Incoming or outgoing data passes through a FIFO, the status of which is
-// available in some of the bits in FIFO_STATUS. This (bidirectional) FIFO is
-// the primary means of transferring data, commands, flow-control, and status
-// information between the host and board.
-//
-#define FIFO_DATA 0
-
-// Another way of passing information between the board and the host is
-// through "mailboxes". Unlike a FIFO, a mailbox holds only a single byte of
-// data.  Writing data to the mailbox causes a status bit to be set, and
-// potentially interrupting the intended receiver. The sender has some way to
-// determine whether the data has been read yet; as soon as it has, it may send
-// more. The mailboxes are handled differently on -II and -IIEX products, as
-// suggested below.
-//------------------------------------------------------------------------------
-// Read: Status Register for IntelliPort-II or -IIEX
-// The presence of any bit set here will cause an interrupt to the host,
-// provided the corresponding bit has been unmasked in the interrupt mask
-// register. Furthermore, interrupts to the host are disabled globally until the
-// loadware selects the irq line to use. With the exception of STN_MR, the bits

-
-// The following exists only on the Intelliport-IIEX, and indicates that the

-//
-#define STE_OUT_MAIL 0x80  // Outbound mailbox full (!)
-
-// The following bits are defined differently for -II and -IIEX boards. Code

-
-// Bit map of status bits only on -II

-// Fifo has been RESET (cleared when the status register is read). Note that
-// this condition cannot be masked and would always interrupt the host, except
-// that the hardware reset also disables interrupts globally from the board
-// until re-enabled by loadware. This could also arise from the

-// used here.

-// 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 noticable, 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.
-
-All Loadware begins with a header area which has a particular format. This
-includes a magic number which identifies the file as being (purportedly)
-loadware, CRC (for the loader), and version information.

-//------------------------------------------------------------------------------
-// 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.

-// 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

-//-----------------------------------------------
-// Revision History:
-//
-// 10 October 1991   MAG First draft
-// 24 February 1992  MAG Additions for 1.4.x loadware
-// 11 March 1992     MAG New status packets
-//
-//-----------------------------------------------
-
-//------------------------------------------------------------------------------
-// Packet Formats:
-//
-// 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.

-// is explicitly defined here. That is the flow-control packet. This is never

- * This array defines the hardware irq and address for up to IP2_MAX_BOARDS
- * (4 supported per ip2_types.h) ISA board addresses and irqs MUST be specified,
- * PCI and EISA boards are probed for and automagicly configed
- * iff the addresses are set to 1 and 2 respectivily.
- *    0x0100 - 0x03f0 == ISA

- *	         2        == EISA
- *	         0        == (skip this board)
- * This array defines the hardware addresses for them. Special 
- * addresses are EISA and PCI which go sniffing for boards. 
-
- * In a multiboard system the position in the array determines which port
- * devices are assigned to each board: 
- *		board 0 is assigned ttyF0.. to ttyF63, 
- *		board 1 is assigned ttyF64  to ttyF127,
- *		board 2 is assigned ttyF128 to ttyF191,
- *		board 3 is assigned ttyF192 to ttyF255. 
- *
- * In PCI and EISA bus systems each range is mapped to card in 
- * monotonically increasing slot number order, ISA position is as specified
- * here.
-
- * 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 
- * specified, while PCI and EISA boards any nonzero entry 
- * will enable interrupts using the BIOS configured irq for the board. 
- * An invalid irq entry will default to polled mode for that card and print
- * console warning.
- 
- * When the driver is loaded as a module these setting can be overridden on the 
- * modprobe command line or on an option line in /etc/modprobe.conf.
- * If the driver is built-in the configuration must be 
- * set here for ISA cards and address set to 1 and 2 for PCI and EISA.
- *
- * Here is an example that shows most if not all possibe combinations:
-
- *static ip2config_t ip2config =
- *{
- *	{11,1,0,0},		// irqs
- *	{				// Addresses
- *		0x0308,		// Board 0, ttyF0   - ttyF63// ISA card at io=0x308, irq=11
- *		0x0001,		// Board 1, ttyF64  - ttyF127//PCI card configured by BIOS
- *		0x0000,		// Board 2, ttyF128 - ttyF191// Slot skipped
- *		0x0002		// Board 3, ttyF192 - ttyF255//EISA card configured by BIOS
- *												 // but polled not irq driven
- *	}
- *};

- /* This structure is NOW always initialized when the driver is initialized.

-// 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
-//
-// For internal use only

- *	Original driver code supplied by Multi-Tech
- *
- *	Changes
- *	1/9/98	alan@lxorguk.ukuu.org.uk
- *					Merge to 2.0.x kernel tree
- *					Obtain and use official major/minors
- *					Loader switched to a misc device
- *					(fixed range check bug as a side effect)
- *					Printk clean up
- *	9/12/98	alan@lxorguk.ukuu.org.uk
- *					Rough port to 2.1.x
- *
- *	10/6/99 sameer			Merged the ISA and PCI drivers to
- *					a new unified driver.
- *
- *	3/9/99	sameer			Added support for ISI4616 cards.
- *
- *	16/9/99	sameer			We do not force RTS low anymore.
- *					This is to prevent the firmware
- *					from getting confused.
- *
- *	26/10/99 sameer			Cosmetic changes:The driver now
- *					dumps the Port Count information
- *					along with I/O address and IRQ.
- *
- *	13/12/99 sameer			Fixed the problem with IRQ sharing.
- *
- *	10/5/00  sameer			Fixed isicom_shutdown_board()
- *					to not lower DTR on all the ports
- *					when the last port on the card is
- *					closed.
- *
- *	10/5/00  sameer			Signal mask setup command added
- *					to  isicom_setup_port and
- *					isicom_shutdown_port.
- *
- *	24/5/00  sameer			The driver is now SMP aware.
- *
- *
- *	27/11/00 Vinayak P Risbud	Fixed the Driver Crash Problem
- *
- *
- *	03/01/01  anil .s		Added support for resetting the
- *					internal modems on ISI cards.
- *
- *	08/02/01  anil .s		Upgraded the driver for kernel
- *					2.4.x
- *
- *	11/04/01  Kevin			Fixed firmware load problem with
- *					ISIHP-4X card
- *
- *	30/04/01  anil .s		Fixed the remote login through
- *					ISI port problem. Now the link
- *					does not go down before password
- *					prompt.
- *
- *	03/05/01  anil .s		Fixed the problem with IRQ sharing
- *					among ISI-PCI cards.
- *
- *	03/05/01  anil .s		Added support to display the version
- *					info during insmod as well as module
- *					listing by lsmod.
- *
- *	10/05/01  anil .s		Done the modifications to the source
- *					file and Install script so that the
- *					same installation can be used for
- *					2.2.x and 2.4.x kernel.
- *
- *	06/06/01  anil .s		Now we drop both dtr and rts during
- *					shutdown_port as well as raise them
- *					during isicom_config_port.
- *
- *	09/06/01 acme@conectiva.com.br	use capable, not suser, do
- *					restore_flags on failure in
- *					isicom_send_break, verify put_user
- *					result
- *
- *	11/02/03  ranjeeth		Added support for 230 Kbps and 460 Kbps
- *					Baud index extended to 21
- *
- *	20/03/03  ranjeeth		Made to work for Linux Advanced server.
- *					Taken care of license warning.
- *
- *	10/12/03  Ravindra		Made to work for Fedora Core 1 of
- *					Red Hat Distribution
- *
- *	06/01/05  Alan Cox 		Merged the ISI and base kernel strands
- *					into a single 2.6 driver
- *
- *	***********************************************************
- *
- *	To use this driver you also need the support package. You
- *	can find this in RPM format on
- *		ftp://ftp.linux.org.uk/pub/linux/alan
- *
- *	You can find the original tools for this direct from Multitech
- *		ftp://ftp.multitech.com/ISI-Cards/
- *
- *	Having installed the cards the module options (/etc/modprobe.conf)
- *
- *	options isicom   io=card1,card2,card3,card4 irq=card1,card2,card3,card4
- *
- *	Omit those entries for boards you don't have installed.
- *
- *	TODO

- *	stli_brdconf[] array is a board. Each line contains io/irq/memory
- *	ranges for that board (as well as what type of board it is).
- *	Some examples:
- *		{ BRD_ECP, 0x2a0, 0, 0xcc000, 0, 0 },
- *	This line will configure an EasyConnection 8/64 at io address 2a0,
- *	and shared memory address of cc000. Multiple EasyConnection 8/64
- *	boards can share the same shared memory address space. No interrupt
- *	is required for this board type.
- *	Another example:
- *		{ BRD_ECPE, 0x5000, 0, 0x80000000, 0, 0 },
- *	This line will configure an EasyConnection 8/64 EISA in slot 5 and
- *	shared memory address of 0x80000000 (2 GByte). Multiple
- *	EasyConnection 8/64 EISA boards can share the same shared memory
- *	address space. No interrupt is required for this board type.
- *	Another example:
- *		{ BRD_ONBOARD, 0x240, 0, 0xd0000, 0, 0 },
- *	This line will configure an ONboard (ISA type) at io address 240,
- *	and shared memory address of d0000. Multiple ONboards can share
- *	the same shared memory address space. No interrupt required.
- *	Another example:
- *		{ BRD_BRUMBY4, 0x360, 0, 0xc8000, 0, 0 },
- *	This line will configure a Brumby board (any number of ports!) at
- *	io address 360 and shared memory address of c8000. All Brumby boards
- *	configured into a system must have their own separate io and memory
- *	addresses. No interrupt is required.
- *	Another example:
- *		{ BRD_STALLION, 0x330, 0, 0xd0000, 0, 0 },
- *	This line will configure an original Stallion board at io address 330
- *	and shared memory address d0000 (this would only be valid for a "V4.0"
- *	or Rev.O Stallion board). All Stallion boards configured into the
- *	system must have their own separate io and memory addresses. No

- *
- * TO DO:

- *	Partly done: 	hooks so you can pull off frames to non tty devs
- *	Restart DLCI 0 when it closes ?
- *	Test basic encoding
- *	Improve the tx engine
- *	Resolve tx side locking by adding a queue_head and routing
- *		all control traffic via it
- *	General tidy/document
- *	Review the locking/move to refcounts more (mux now moved to an
- *		alloc/free model ready)
- *	Use newest tty open/close port helpers and install hooks
- *	What to do about power functions ?
- *	Termios setting and negotiation
- *	Do we need a 'which mux are you' ioctl to correlate mux and tty sets

-/* generic HDLC line discipline for Linux
- *
- * Written by Paul Fulghum paulkf@microgate.com
- * for Microgate Corporation
- *
- * Microgate and SyncLink are registered trademarks of Microgate Corporation
- *
- * Adapted from ppp.c, written by Michael Callahan <callahan@maths.ox.ac.uk>,
- *	Al Longyear <longyear@netcom.com>,
- *	Paul Mackerras <Paul.Mackerras@cs.anu.edu.au>
- *
- * Original release 01/11/99
- *
- * This code is released under the GNU General Public License (GPL)
- *
- * This module implements the tty line discipline N_HDLC for use with
- * tty device drivers that support bit-synchronous HDLC communications.
- *
- * All HDLC data is frame oriented which means:
- *
- * 1. tty write calls represent one complete transmit frame of data
- *    The device driver should accept the complete frame or none of 
- *    the frame (busy) in the write method. Each write call should have
- *    a byte count in the range of 2-65535 bytes (2 is min HDLC frame
- *    with 1 addr byte and 1 ctrl byte). The max byte count of 65535
- *    should include any crc bytes required. For example, when using
- *    CCITT CRC32, 4 crc bytes are required, so the maximum size frame
- *    the application may transmit is limited to 65531 bytes. For CCITT
- *    CRC16, the maximum application frame size would be 65533.
- *
- *
- * 2. receive callbacks from the device driver represents
- *    one received frame. The device driver should bypass
- *    the tty flip buffer and call the line discipline receive
- *    callback directly to avoid fragmenting or concatenating
- *    multiple frames into a single receive callback.
- *
- *    The HDLC line discipline queues the receive frames in separate
- *    buffers so complete receive frames can be returned by the
- *    tty read calls.
- *
- * 3. tty read calls returns an entire frame of data or nothing.
- *    
- * 4. all send and receive data is considered raw. No processing
- *    or translation is performed by the line discipline, regardless
- *    of the tty flags
- *
- * 5. When line discipline is queried for the amount of receive
- *    data available (FIOC), 0 is returned if no data available,
- *    otherwise the count of the next available frame is returned.
- *    (instead of the sum of all received frame counts).
- *
- * These conventions allow the standard tty programming interface
- * to be used for synchronous HDLC applications when used with
- * this line discipline (or another line discipline that is frame
- * oriented such as N_PPP).
- *
- * The SyncLink driver (synclink.c) implements both asynchronous
- * (using standard line discipline N_TTY) and synchronous HDLC
- * (using N_HDLC) communications, with the latter using the above
- * conventions.
- *
- * This implementation is very basic and does not maintain
- * any statistics. The main point is to enforce the raw data
- * and frame orientation of HDLC communications.

- * n_tty.c --- implements the N_TTY line discipline.
- *
- * This code used to be in tty_io.c, but things are getting hairy
- * enough that it made sense to split things off.  (The N_TTY
- * processing has changed so much that it's hardly recognizable,
- * anyway...)
- *
- * Note that the open routine for N_TTY is guaranteed never to return
- * an error.  This is because Linux will fall back to setting a line
- * to N_TTY if it can not switch to any other line discipline.

+ * uncertainty about the initial state, he/she can only shuffle that
+ * uncertainty about, but never cause any collisions (which would
+ * decrease the uncertainty).
+ *
+ * Our mixing functions were analyzed by Lacharme, Roeck, Strubel, and
+ * Videau in their paper, "The Linux Pseudorandom Number Generator
+ * Revisited" (see: http://eprint.iacr.org/2012/251.pdf).  In their
+ * paper, they point out that we are not using a true Twisted GFSR,
+ * since Matsumoto & Kurita used a trinomial feedback polynomial (that
+ * is, with only three taps, instead of the six that we are using).
+ * As a result, the resulting polynomial is neither primitive nor
+ * irreducible, and hence does not have a maximal period over
+ * GF(2**32).  They suggest a slight change to the generator
+ * polynomial which improves the resulting TGFSR polynomial to be
+ * irreducible, which we have made here.

-		 ** 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.

- * Kernel Synchronization:

- * This driver has 2 kernel control paths - exception handlers (calls into the driver
- * from user mode) and the timer bottom half (tasklet).  This is a polled driver, interrupts
- * are not used.
- *
- * Critical data: 
- * -  rp_table[], accessed through passed "info" pointers, is a global (static) array of 
- *    serial port state information and the xmit_buf circular buffer.  Protected by 
- *    a per port spinlock.
- * -  xmit_flags[], an array of ints indexed by line (port) number, indicating that there
- *    is data to be transmitted.  Protected by atomic bit operations.
- * -  rp_num_ports, int indicating number of open ports, protected by atomic operations.
- * 
- * rp_write() and rp_write_char() functions use a per port semaphore to protect against
- * simultaneous access to the same port by more than one process.

- * extra work of storing the value doesn't count, since a delay is
- * needed after a SCC access anyway. Additionally, _SCCwrite() manages
- * writes to WR0 and WR8 differently, because these can be accessed
- * directly with less overhead. Another special case are WR7 and WR7'.
- * _SCCwrite automatically checks what of this registers is selected
- * and changes b0 of WR15 if needed.
- * 
- * _SCCread() for standard read registers is straightforward, except
- * for RR2 (split into two "virtual" registers: one for the value
- * written to WR2 (from the shadow) and one for the vector including
- * status from RR2, Ch. B) and RR3. The latter must be read from
- * Channel A, because it reads as all zeros on Ch. B. RR0 and RR8 can
- * be accessed directly as before.
- * 
- * The two inline function contain complicated switch statements. But
- * I rely on regno and final_delay being constants, so gcc can reduce
- * the whole stuff to just some assembler statements.
- * 
- * _SCCwrite and _SCCread aren't intended to be used directly under
- * normal circumstances. The macros SCCread[_ND] and SCCwrite[_ND] are
- * for that purpose. They assume that a local variable 'port' is
- * declared and pointing to the port's scc_struct entry. The
- * variants with "_NB" appended should be used if no other SCC
- * accesses follow immediately (within 0.5 usecs). They just skip the
- * final delay nops.
- * 
- * Please note that accesses to SCC registers should only take place
- * when interrupts are turned off (at least if SCC interrupts are
- * enabled). Otherwise, an interrupt could interfere with the
- * two-stage accessing process.

-/***************************** Documentation ************************/
-/*
- * 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.

- * 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

- * Revision 1.1:  April 14th 1997.
- *                Incorporated Richard Hudsons suggestions,
- *                removed some debugging printk's.
- * Revision 1.2:  April 15th 1997.
- *                Ported to 2.1.x kernels.
- * Revision 1.3:  April 17th 1997
- *                Backported to 2.0. (Compatibility macros).
- * Revision 1.4:  April 18th 1997
- *                Fixed DTR/RTS bug that caused the card to indicate
- *                "don't send data" to a modem after the password prompt.
- *                Fixed bug for premature (fake) interrupts.
- * Revision 1.5:  April 19th 1997
- *                fixed a minor typo in the header file, cleanup a little.
- *                performance warnings are now MAXed at once per minute.
- * Revision 1.6:  May 23 1997
- *                Changed the specialix=... format to include interrupt.
- * Revision 1.7:  May 27 1997
- *                Made many more debug printk's a compile time option.
- * Revision 1.8:  Jul 1  1997
- *                port to linux-2.1.43 kernel.
- * Revision 1.9:  Oct 9  1998
- *                Added stuff for the IO8+/PCI version.
- * Revision 1.10: Oct 22  1999 / Jan 21 2000.
- *                Added stuff for setserial.

- * 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, continueing 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 loosing 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.

- * linux/drivers/char/synclink.c
- *
- * $Id: synclink.c,v 4.38 2005/11/07 16:30:34 paulkf Exp $
- *
- * Device driver for Microgate SyncLink ISA and PCI
- * high speed multiprotocol serial adapters.
- *
- * written by Paul Fulghum for Microgate Corporation
- * paulkf@microgate.com
- *
- * Microgate and SyncLink are trademarks of Microgate Corporation
- *
- * Derived from serial.c written by Theodore Ts'o and Linus Torvalds
- *
- * Original release 01/11/99
- *
- * This code is released under the GNU General Public License (GPL)
- *
- * This driver is primarily intended for use in synchronous
- * HDLC mode. Asynchronous mode is also provided.
- *
- * When operating in synchronous mode, each call to mgsl_write()
- * contains exactly one complete HDLC frame. Calling mgsl_put_char
- * will start assembling an HDLC frame that will not be sent until
- * mgsl_flush_chars or mgsl_write is called.
- * 
- * Synchronous receive data is reported as complete frames. To accomplish
- * this, the TTY flip buffer is bypassed (too small to hold largest
- * frame and may fragment frames) and the line discipline
- * receive entry point is called directly.
- *
- * This driver has been tested with a slightly modified ppp.c driver
- * for synchronous PPP.
- *
- * 2000/02/16
- * Added interface for syncppp.c driver (an alternate synchronous PPP
- * implementation that also supports Cisco HDLC). Each device instance
- * registers as a tty device AND a network device (if dosyncppp option
- * is set for the device). The functionality is determined by which
- * device interface is opened.
- *

- * Buffer Structures:
- *
- * Normal memory access uses virtual addresses that can make discontiguous
- * physical memory pages appear to be contiguous in the virtual address
- * space (the processors memory mapping handles the conversions).
- *
- * DMA transfers require physically contiguous memory. This is because
- * the DMA system controller and DMA bus masters deal with memory using
- * only physical addresses.
- *
- * This causes a problem under Windows NT when large DMA buffers are
- * needed. Fragmentation of the nonpaged pool prevents allocations of
- * physically contiguous buffers larger than the PAGE_SIZE.
- *
- * However the 16C32 supports Bus Master Scatter/Gather DMA which
- * allows DMA transfers to physically discontiguous buffers. Information
- * about each data transfer buffer is contained in a memory structure
- * called a 'buffer entry'. A list of buffer entries is maintained
- * to track and control the use of the data transfer buffers.
- *
- * To support this strategy we will allocate sufficient PAGE_SIZE
- * contiguous memory buffers to allow for the total required buffer
- * space.
- *
- * The 16C32 accesses the list of buffer entries using Bus Master
- * DMA. Control information is read from the buffer entries by the
- * 16C32 to control data transfers. status information is written to
- * the buffer entries by the 16C32 to indicate the status of completed
- * transfers.
- *
- * The CPU writes control information to the buffer entries to control
- * the 16C32 and reads status information from the buffer entries to
- * determine information about received and transmitted frames.
- *
- * Because the CPU and 16C32 (adapter) both need simultaneous access
- * to the buffer entries, the buffer entry memory is allocated with
- * HalAllocateCommonBuffer(). This restricts the size of the buffer
- * entry list to PAGE_SIZE.
- *
- * The actual data buffers on the other hand will only be accessed
- * by the CPU or the adapter but not by both simultaneously. This allows
- * Scatter/Gather packet based DMA procedures for using physically
- * discontiguous pages.

- * 'tty_io.c' gives an orthogonal feeling to tty's, be they consoles
- * or rs-channels. It also implements echoing, cooked mode etc.
- *
- * Kill-line thanks to John T Kohl, who also corrected VMIN = VTIME = 0.
- *
- * Modified by Theodore Ts'o, 9/14/92, to dynamically allocate the
- * tty_struct and tty_queue structures.  Previously there was an array
- * of 256 tty_struct's which was statically allocated, and the
- * tty_queue structures were allocated at boot time.  Both are now
- * dynamically allocated only when the tty is open.
- *
- * Also restructured routines so that there is more of a separation
- * between the high-level tty routines (tty_io.c and tty_ioctl.c) and
- * the low-level tty routines (serial.c, pty.c, console.c).  This
- * makes for cleaner and more compact code.  -TYT, 9/17/92
- *
- * Modified by Fred N. van Kempen, 01/29/93, to add line disciplines
- * which can be dynamically activated and de-activated by the line
- * discipline handling modules (like SLIP).
- *
- * NOTE: pay no attention to the line discipline code (yet); its
- * interface is still subject to change in this version...
- * -- TYT, 1/31/92
- *
- * Added functionality to the OPOST tty handling.  No delays, but all
- * other bits should be there.
- *	-- Nick Holloway <alfie@dcs.warwick.ac.uk>, 27th May 1993.
- *
- * Rewrote canonical mode and added more termios flags.
- * 	-- julian@uhunix.uhcc.hawaii.edu (J. Cowley), 13Jan94
- *
- * Reorganized FASYNC support so mouse code can share it.
- *	-- ctm@ardi.com, 9Sep95
- *
- * New TIOCLINUX variants added.
- *	-- mj@k332.feld.cvut.cz, 19-Nov-95
- *
- * Restrict vt switching via ioctl()
- *      -- grif@cs.ucr.edu, 5-Dec-95
- *
- * Move console and virtual terminal code to more appropriate files,
- * implement CONFIG_VT and generalize console device interface.
- *	-- Marko Kohtala <Marko.Kohtala@hut.fi>, March 97
- *
- * Rewrote tty_init_dev and tty_release_dev to eliminate races.
- *	-- Bill Hawes <whawes@star.net>, June 97
- *
- * Added devfs support.
- *      -- C. Scott Ananian <cananian@alumni.princeton.edu>, 13-Jan-1998
- *
- * Added support for a Unix98-style ptmx device.
- *      -- C. Scott Ananian <cananian@alumni.princeton.edu>, 14-Jan-1998
- *
- * Reduced memory usage for older ARM systems
- *      -- Russell King <rmk@arm.linux.org.uk>
- *
- * Move do_SAK() into process context.  Less stack use in devfs functions.
- * alloc_tty_struct() always uses kmalloc()

- *   The abstract console driver provides a generic interface for a text
- *   console. It supports VGA text mode, frame buffer based graphical consoles
- *   and special graphics processors that are only accessible through some
- *   registers (e.g. a TMS340x0 GSP).
- *
- *   The interface to the hardware is specified using a special structure
- *   (struct consw) which contains function pointers to console operations
- *   (see <linux/console.h> for more information).
