linux下vme总线驱动代码

This set of programs is designed to allow access to the VMEbus
through the Tundra Semiconductor Universe and Universe II CA91C042
PCI-VME bridge chips.  This popular chip is found on many Intel
VMEbus Processors including those from:

Dynatem, Concurrent Technologies, Xycom, SBS/Or Computer

This driver will only work with the 2.2.x and 2.4.x Linux kernels and was
last tested with 2.4.7.  Also, you must have the GCC compiler 
version 2.95.x.  This program has been made to work with the EGCS
compiler with modifications from some of our users, but the
VMELinux Project has only enough time for one compiler.  Anyway,
the two compiler projects are merging back together soon so this
will all be a moot point.  GCC 3.0 seems to work but has not been tested
fully.

To install the VMELinux driver and access programs do the following:

Change into the ca91c042 directory and follow the instructions in the
INSTALL file.

Change into the vmeutils directory and follow the instructions in the
INSTALL file.

Change into the vmeshell directory and follow the instructions in the
INSTALL file.

The ca91c042 directory contains a C program which is a Linux Kernel
Module.  It can be added and removed from an operating Linux system.

The vmeutils directory contains a C++ source which creates a program
that can access the ca91c042 driver through some file in the /dev
directory.  It also serves as an example of how to access the driver
for other programs.

The vmeshell directory contains shell scripts that access the vmeutils
program from the command prompt.  These scripts are very useful for
casual access to the VMEbus.

What is missing from the file collection is an example of how to use
the ca91c042 driver for interrupts and other real-time access.  The
proper method for this is to write another kernel module program in C
that accesses the routines loaded by the ca91c042 module.  An example
of this will be coming soon to www.vmelinux.org.

The VMELinux Project started out only as a method of getting access to
the VMEbus using Linux and Intel based processor boards.  It serves
this purpose well, but has grown into a decent VMEbus solution for
more severe tasks.  One company is relying on VMELinux and Linux to
provide Real-Time access to custom VMEbus boards with Interrupt rates
in excess of 2000 Hz.

We hope you enjoy the use of Linux in your VMEbus solution.  This file
