-================================================
-Comtrol(tm) RocketPort(R)/RocketModem(TM) Series
-================================================
-
-Device Driver for the Linux Operating System
-============================================
-
-Product overview
-----------------
-
-This driver provides a loadable kernel driver for the Comtrol RocketPort
-and RocketModem PCI boards. These boards provide, 2, 4, 8, 16, or 32
-high-speed serial ports or modems. This driver supports up to a combination
-of four RocketPort or RocketModems boards in one machine simultaneously.
-This file assumes that you are using the RocketPort driver which is
-integrated into the kernel sources.
-
-The driver can also be installed as an external module using the usual
-"make;make install" routine. This external module driver, obtainable
-from the Comtrol website listed below, is useful for updating the driver
-or installing it into kernels which do not have the driver configured
-into them. Installations instructions for the external module
-are in the included README and HW_INSTALL files.
-
-RocketPort ISA and RocketModem II PCI boards currently are only supported by
-this driver in module form.
-
-The RocketPort ISA board requires I/O ports to be configured by the DIP
-switches on the board. See the section "ISA Rocketport Boards" below for
-information on how to set the DIP switches.
-
-You pass the I/O port to the driver using the following module parameters:
-
-board1:
- I/O port for the first ISA board
-board2:
- I/O port for the second ISA board
-board3:
- I/O port for the third ISA board
-board4:
- I/O port for the fourth ISA board
-
-There is a set of utilities and scripts provided with the external driver
-(downloadable from http://www.comtrol.com) that ease the configuration and
-setup of the ISA cards.
-
-The RocketModem II PCI boards require firmware to be loaded into the card
-before it will function. The driver has only been tested as a module for this
-board.
-
-Installation Procedures
------------------------
-
-RocketPort/RocketModem PCI cards require no driver configuration, they are
-automatically detected and configured.
-
-The RocketPort driver can be installed as a module (recommended) or built
-into the kernel. This is selected, as for other drivers, through the `make config`
-command from the root of the Linux source tree during the kernel build process.
-
-The RocketPort/RocketModem serial ports installed by this driver are assigned
-device major number 46, and will be named /dev/ttyRx, where x is the port number
-starting at zero (ex. /dev/ttyR0, /devttyR1, ...). If you have multiple cards
-installed in the system, the mapping of port names to serial ports is displayed
-in the system log at /var/log/messages.
-
-If installed as a module, the module must be loaded. This can be done
-manually by entering "modprobe rocket". To have the module loaded automatically
-upon system boot, edit a `/etc/modprobe.d/*.conf` file and add the line
-"alias char-major-46 rocket".
-
-In order to use the ports, their device names (nodes) must be created with mknod.
-This is only required once, the system will retain the names once created. To
-create the RocketPort/RocketModem device names, use the command
-"mknod /dev/ttyRx c 46 x" where x is the port number starting at zero.
-
-For example::
-
- > mknod /dev/ttyR0 c 46 0
- > mknod /dev/ttyR1 c 46 1
- > mknod /dev/ttyR2 c 46 2
-
-The Linux script MAKEDEV will create the first 16 ttyRx device names (nodes)
-for you::
-
- >/dev/MAKEDEV ttyR
-
-ISA Rocketport Boards
----------------------
-
-You must assign and configure the I/O addresses used by the ISA Rocketport
-card before installing and using it. This is done by setting a set of DIP
-switches on the Rocketport board.
-
-
-Setting the I/O address
------------------------
-
-Before installing RocketPort(R) or RocketPort RA boards, you must find
-a range of I/O addresses for it to use. The first RocketPort card
-requires a 68-byte contiguous block of I/O addresses, starting at one
-of the following: 0x100h, 0x140h, 0x180h, 0x200h, 0x240h, 0x280h,
-0x300h, 0x340h, 0x380h. This I/O address must be reflected in the DIP
-switches of *all* of the Rocketport cards.
-
-The second, third, and fourth RocketPort cards require a 64-byte
-contiguous block of I/O addresses, starting at one of the following
-I/O addresses: 0x100h, 0x140h, 0x180h, 0x1C0h, 0x200h, 0x240h, 0x280h,
-0x2C0h, 0x300h, 0x340h, 0x380h, 0x3C0h. The I/O address used by the
-second, third, and fourth Rocketport cards (if present) are set via
-software control. The DIP switch settings for the I/O address must be
-set to the value of the first Rocketport cards.
-
-In order to distinguish each of the card from the others, each card
-must have a unique board ID set on the dip switches. The first
-Rocketport board must be set with the DIP switches corresponding to
-the first board, the second board must be set with the DIP switches
-corresponding to the second board, etc. IMPORTANT: The board ID is
-the only place where the DIP switch settings should differ between the
-various Rocketport boards in a system.
-
-The I/O address range used by any of the RocketPort cards must not
-conflict with any other cards in the system, including other
-RocketPort cards. Below, you will find a list of commonly used I/O
-address ranges which may be in use by other devices in your system.
-On a Linux system, "cat /proc/ioports" will also be helpful in
-identifying what I/O addresses are being used by devices on your
-system.
-
-Remember, the FIRST RocketPort uses 68 I/O addresses. So, if you set it
-for 0x100, it will occupy 0x100 to 0x143. This would mean that you
-CAN NOT set the second, third or fourth board for address 0x140 since
-the first 4 bytes of that range are used by the first board. You would
-need to set the second, third, or fourth board to one of the next available
-blocks such as 0x180.

-/* 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 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.

- * 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.

-Function: sPCIInitController
-Purpose: Initialization of controller global registers and controller
- structure.
-Call: sPCIInitController(CtlP,CtlNum,AiopIOList,AiopIOListSize,
- IRQNum,Frequency,PeriodicOnly)
- CONTROLLER_T *CtlP; Ptr to controller structure
- int CtlNum; Controller number
- ByteIO_t *AiopIOList; List of I/O addresses for each AIOP.
- This list must be in the order the AIOPs will be found on the
- controller. Once an AIOP in the list is not found, it is
- assumed that there are no more AIOPs on the controller.
- int AiopIOListSize; Number of addresses in AiopIOList
- int IRQNum; Interrupt Request number. Can be any of the following:
- 0: Disable global interrupts
- 3: IRQ 3
- 4: IRQ 4
- 5: IRQ 5
- 9: IRQ 9
- 10: IRQ 10
- 11: IRQ 11
- 12: IRQ 12
- 15: IRQ 15
- Byte_t Frequency: A flag identifying the frequency
- of the periodic interrupt, can be any one of the following:
- FREQ_DIS - periodic interrupt disabled
- FREQ_137HZ - 137 Hertz
- FREQ_69HZ - 69 Hertz
- FREQ_34HZ - 34 Hertz
- FREQ_17HZ - 17 Hertz
- FREQ_9HZ - 9 Hertz
- FREQ_4HZ - 4 Hertz
- If IRQNum is set to 0 the Frequency parameter is
- overidden, it is forced to a value of FREQ_DIS.
- int PeriodicOnly: 1 if all interrupts except the periodic
- interrupt are to be blocked.
- 0 is both the periodic interrupt and
- other channel interrupts are allowed.
- If IRQNum is set to 0 the PeriodicOnly parameter is
- overidden, it is forced to a value of 0.
-Return: int: Number of AIOPs on the controller, or CTLID_NULL if controller
- initialization failed.
-
-Comments:
- If periodic interrupts are to be disabled but AIOP interrupts
- are allowed, set Frequency to FREQ_DIS and PeriodicOnly to 0.
-
- If interrupts are to be completely disabled set IRQNum to 0.
-
- Setting Frequency to FREQ_DIS and PeriodicOnly to 1 is an
- invalid combination.
-
- This function performs initialization of global interrupt modes,
- but it does not actually enable global interrupts. To enable
- and disable global interrupts use functions sEnGlobalInt() and
- sDisGlobalInt(). Enabling of global interrupts is normally not
- done until all other initializations are complete.
-
- Even if interrupts are globally enabled, they must also be
- individually enabled for each channel that is to generate
- interrupts.
-
-Warnings: No range checking on any of the parameters is done.
-
- No context switches are allowed while executing this function.
-
- After this function all AIOPs on the controller are disabled,
- they can be enabled with sEnAiop().

-Function: sInitController
-Purpose: Initialization of controller global registers and controller
- structure.
-Call: sInitController(CtlP,CtlNum,MudbacIO,AiopIOList,AiopIOListSize,
- IRQNum,Frequency,PeriodicOnly)
- CONTROLLER_T *CtlP; Ptr to controller structure
- int CtlNum; Controller number
- ByteIO_t MudbacIO; Mudbac base I/O address.
- ByteIO_t *AiopIOList; List of I/O addresses for each AIOP.
- This list must be in the order the AIOPs will be found on the
- controller. Once an AIOP in the list is not found, it is
- assumed that there are no more AIOPs on the controller.
- int AiopIOListSize; Number of addresses in AiopIOList
- int IRQNum; Interrupt Request number. Can be any of the following:
- 0: Disable global interrupts
- 3: IRQ 3
- 4: IRQ 4
- 5: IRQ 5
- 9: IRQ 9
- 10: IRQ 10
- 11: IRQ 11
- 12: IRQ 12
- 15: IRQ 15
- Byte_t Frequency: A flag identifying the frequency
- of the periodic interrupt, can be any one of the following:
- FREQ_DIS - periodic interrupt disabled
- FREQ_137HZ - 137 Hertz
- FREQ_69HZ - 69 Hertz
- FREQ_34HZ - 34 Hertz
- FREQ_17HZ - 17 Hertz
- FREQ_9HZ - 9 Hertz
- FREQ_4HZ - 4 Hertz
- If IRQNum is set to 0 the Frequency parameter is
- overidden, it is forced to a value of FREQ_DIS.
- int PeriodicOnly: 1 if all interrupts except the periodic
- interrupt are to be blocked.

-Warnings: No range checking on any of the parameters is done.
