1. Introduction

The Interface Consultants Model VIS1018 Ikon SGI device driver is a program that accesses the PCI bus to configure an Ikon board to drive Versatec and compatible plotters, hence the name VIP (Versatec Ikon PCI).

The device driver supports the Ikon 10117 Hardcopy PCI bus interface board under SGI IRIX 6.4 operating system environment.

A test program ‘viptest’ is provided (with C source code) that produces both print and plot mode data.

A file output program ‘vipdma’ is also provided that allows files to be output to a plotter in print or plot mode, or a printer using high speed DMA.

The device driver supports the operation of multiple Ikon boards on a single machine. The driver will identify the boards as devices /hw/vip0, /hw/vip1, ...

Note that the device special files are under the '/hw' tree in IRIX 6.4, not the Unix standard '/dev' tree. If your software requires other names, create a symbolic link to the real device special files.

The installation script handles all boards under IRIX 6.4, and more boards can added later without any additional software installation.

NOTE: This device driver software requires a special Ikon 10117 board labeled 'VIS1018 Interface Consultants'. This device driver will not operate properly with any other board.

Disclaimer: Marks copyright Interface Consultants, Ikon, or Xerox.

2. Installation of the software

The installation of the VIP1018 can be accomplished easily and quickly with the included CD.

(Note: you must be logged in as super user 'root' in order to perform the file copies required for installation.)

First, insert the CD into the CD-ROM drive. Access the CD drive by typing:

cd /CDROM

Next, run the vinstall script on the CD by typing:

csh ./vinstall

The device driver is self-configuring. At this point, the device driver should be functional. A test utility (such as the viptest utility included) can be run at this time to test the driver. The machine should be rebooted to make sure the device driver is properly loaded and configured.

To install from the tar floppy disk, insert the floppy into the disk drive, and extract the files into a temporary working directory:

tar -xvf /dev/fd0

Next, run the vinstall script in the working directory by typing:

csh ./vinstall

3. Deinstallation of the software

The deinstallation of the VIS1018 is similar in nature to the installation process by virtue of its ease and speed.

First, insert the CD into the CD-ROM drive. Access the CD drive by typing:

cd /CDROM

First, insert the CD into the CD-ROM drive. Next, run the vremove script on the CD by typing:

csh ./vremove

The device driver should be removed at this point. The machine should be rebooted to make sure the device driver is properly removed and to ensure nothing else was affected by the deinstall.

4. Configuring the Ikon board and device driver

The Ikon 10117 board has no external dip-switches to set, as certain other Ikon boards did. Thus there are no physical configurations with the board the user must adjust. There still is a ribbon cable on the board that you may need to adjust to set the board for either Versatec Differential (long lines), or Centronics interface. When installing the board, make sure the board is properly seated in its 32 bit PCI slot. Refer to the Ikon 10117 user’s manual for additional information.

The device driver uses DMA and interrupts to achieve high performance. The Ikon 10117 board possesses a set of PCI configuration registers that configure all of the bus interface information such as the register base address of the "working" registers in the PCI I/O and memory space, and interrupt level. All of the above information is configured at power-on by the IRIX operating system.

Unlike previous AIX incarnations of this line of device drivers that used SMIT to configure the Ikon board, the VIP1018 does not have a direct OS setup interface to change the settings of the Ikon board. The user will need to send IOCTL commands to the board itself to change the configurations (see vpioctl.h). Any settings (handshake speed, timeout value) are retained by the device driver from plot to plot (i.e. between a ‘close()’ and an ‘open()’ call), but need to be re-set after a machine boot or device driver load/unload.

cdR vip_ - -

$$$

Purpose:

This the the ‘master’ file for the vipdd device driver.

Description:

This file describes the driver to the IRIX operating system. It details the following information:

c - this is a character device driver

d - this is a dynamically loadable kernel module

R - this is a auto-registrable dynamically loadable kernel module

vip_ - driver prefix is vip_. This is used by the loader to link to the devswitch functions.

vipdd.o device driver object file

Purpose:

This is the object file image of the device driver that is loaded into the kernel by the ‘ml’ command.

Description:

Device driver object file.

vipdd.sm device driver system file

Contents:

VECTOR: bustype=PCI module=vipdd

Purpose:

This file tells the IRIX operating system that the the device driver object module vipdd.o supports a PCI device.

Description:

When IRIX boots, it loads the device driver module, and calls the ‘prefix_init’ function for all ‘.sm’ files. In this case, it calls the vip_init function. This allows the driver to register the vendor id and device id of the PCI card it supports. When the IRIX probe finds a PCI card, it calls the ‘prefix_attach’ function for the registered vendor id and device id of the PCI card. The vip_attach function initializes the device and driver.

Purpose:

Assigns register values to constants used to interface to the device driver.

Description:

This header file contains all the #defined constants which were used in the device driver routine to substitute for register values. This file is #included in any program that needs to access the device. It defines the IOCTL interface to the driver and the meaning of the return status. This can be incorporated into a program that sends out IOCTL commands to the Ikon board.

Note: since the IRIX operating system has no ‘smit’ setable parameters like the AIX operating system, the handshake speed, device timeout value, and driver debug level are set thru ioctl’s. See vipdma.c for examples of how to issue the ioctl commands.

6. Viptest - test plot and programming example

The viptest program is provided with C source code as an example of how to write a user program that interfaces to the vip device driver.

Typing 'viptest' with no parameters prints the following synopsis:

# viptest

VIP driver test program - Version 3.7 July 24, 1997

Usage: viptest -f<device name>

-f<device name> (e.g. /dev/vip0)

output test print and plot to device

The following is the screen output from a call to the viptest program:

# viptest -f/hw/vip0

VIP driver test program - Version 3.7 July 24, 1997

device name = /hw/vip0

block = 0 cnt=1000

block = 1 cnt=2000

...

block = 58 cnt=59000

block = 59 cnt=60000

The plotter output for viptest is 'hello' in print mode, and then it does dma plot mode of blocks filled with 0xf0. There are 100 blocks sent. The first block is 1000 bytes, and each block is increased in size by 1000 bytes until it rolls over the 16 bit max. Thermal plotters will plot in yellow and white.

To advance the plot out of the plotter, do a manual form feed, or output a form feed command using vipdma as follows:

# vipdma -cVTFF

7. Vipdma - file dma output program

The 'vipdma' program allows files to be output to a plotter or printer in print or plot mode using high speed DMA. Vipdma is double buffered, and executes command line functions in a left to right order as entered. Vipdma is full featured, in that it can perform any plotter function that a user program can issue.

Typing 'vipdma' with no parameters prints the following synopsis:

VIP driver DMA output program - Version 3.7 July 24, 1997

Usage: vipdma -w<> [-d<>] [-m<>] [-f<>] [-c<>] [-v] [-t<>]

-w<output device> (required- e.g. /hw/vip0)

-d<dma_sizein Kb> (optional - default=16 max=128)

-m<mode> mode for transfer, PRINT(default) or PLOT

-f<filename> data file to dma to port

-c<command> Remote command to plotter, can be:

VRST - Versatec Remote Reset

VCLR - Versatec Remote Clear

VTFF - Versatec Remote Form Feed

VEOT - Versatec End or Terminate

VRLT - Versatec Remote Line Terminate

CSTAT - Get current status

LSTAT - Get latched status

VPRINT - Versatec Print Mode

VPLOT - Versatec Plot Mode

VPRINTPLOT - Versatec SPP Mode

VPC_TERMCOM - Versatec Remote Line Terminate

VPC_FFCOM - Versatec Remote Form Feed

VPC_EOTCOM - Versatec End or Terminate

VPC_CLRCOM - Versatec Remote Clear

VPC_RESET - Versatec Remote Reset

VPLT_HS_SPEED_0 - Set Handshake speed 0 fast

VPLT_HS_SPEED_1 - Set Handshake speed 1

VPLT_HS_SPEED_2 - Set Handshake speed 2

VPLT_HS_SPEED_3 - Set Handshake speed 3 slow

VGETSTATE - Get Versatec VPSC Status

LPGETREGS - Get Versatec registers

LPGETTIMVAL - Get Versatec timeout value

LPGETDEBUGLVL - Get driver debug level

-t<timeout> LPSETTIMVAL - Set Versatec timeout

-b<debug lvl> LPSETDEBUGLVL - Set driver debug level

-v verbose mode

Note: args are executed left to right as found, multiple files in

different modes can be sent in a single command.

e.g. vipdma -w/dev/vip0 -d32 -mPRINT -ffile1.prn -mPLOT -ffile2.plt

sends file1.prn in print mode, and then file2.plt in plot mode

Full Versatec 'greensheet' output can be implemented with vipdma if preamble and rewind commands are put into files that are output in print mode, and plot data padded to the correct bytes per scan in color separate files is output in plot mode.

8. Miscellaneous Notes

The device ‘open‘ will succeed even if the plotter is ‘offline.’ This way, an ioctl can be used to determine detailed status (ref. VPLT.CSTAT).

The Ikon board FIFO buffer is cleared on a device timeout and when the device is configured.

The handshake speed, timeout value, and debug level are not system defined attributes, and must be set in the driver via ioctl() function calls. IRIX has no facility equivalent to the AIX ODM to define system attributes. Once set, theses values remain until the device driver is reloaded by the operating system.

There is no ‘programmed I/O’ mode for this driver. It uses PCI bus master DMA at all times for data transfer. The AIX driver had a ‘programmed I/O’ mode selection because it used bus slave DMA, a system resource which might not be available in particular configurations.
