I think many people in the epics community may be interested to know
that there exists a version of Linux for many of the Motorola MVME cards
that we use for IOCs.

Information and downloads are available from:

 http://www.sleepie.demon.co.uk/linuxvme/index.html

I have installed the port successfully on an MVME167 and an MVE162 card
and have been using it for about a month with no problems.  Hardware
requirements are detailed on the site above.

I have successfully compiled and tested the epics client libraries from
R3.13.0beta11 and will shortly move up to R3.13.0beta12.

It is based on the Debian 2.0 Linux distribution so there are a huge
number of packages available for it - all those that I have tried so far
have worked - including such unlikely items as apache and the gimp!!!

Kernel versions available are 2.0.33, 2.1.90 and 2.1.106. Kernel modules
are supported.

There is a /dev/mennc device which can be 'mmap'ed to provide access to
the physical memory of the MVME card.  So far, I have been able to
control Joerger VSC8 & VSC16 scaler cards and am starting work on an OMS
VME8 motor driver.

I believe that this system could be an excellent alternative to
vxWorks/Hideos etc.
