Hello All , In my google searching for examples of (Hopefully correct)
configurations of the qvss in the VAX portion of simh . I have come across
exactly 0 (zero) configuration examples that are not associated with a trouble
ticket or failure in some other part or device in the VAX implementation .

Does such an example exist ?

I too have been looking for proper use of qvss. For that matter I wonder if
there is a tutorial on how to getting DECWindows to work at all. I have
found documentation links on the HPE website but they are all broken.

Thanks

Ray

Hi JimL,

I have a fully working emulation of a MicroVAX II running Ultrix 2.3 and
X11R1 on Linux locally, with the most recent SIMH from git. Is there a
specific configuration you are looking to replicate, or have I
misunderstood your question?

The configuration for at the simh level for one . I've tried putting in
the 'SET CPU MODEL=VAXStation' and 'SET QVSS ENABLE" got me a segmentation fault
.
With just the 'SET CPU MODEL=VAXStation' the config runs without any
difficulties . I am uninformed enough that I am worried that this command needs
other or more configuration in order to bring up *windows* at OS runtime .

If I can get the 'Necessary' and hopefully correct 'SET' commands that
will not cause other or more difficulties .

And BTW I am being very dumbed'down in my requests above as SIMH is of
new use to me . I have a qbus varient of the 3900 (or there abouts) which I
have much time spent on .

A Ray Jewhurst , Is also looking for such info at both the SIMH level &
then in the appropriate configuration at the DecWindows level .

Here are the contents of my SIMH ini file, which may be of use as a
starting point. I am using the microvax2 simulator, compiled locally, and
I wonder if your difficulties stem from using a different or older
executable. What operating system and SIMH version are you using?

Hello Henry , My more recent post begs to wait till we can figure out
how to get my SIMH to 'boot cpu' , then I can try diagnosing qvss further .

Thank you for your config below . I did find out that with only either
of 'set qvss enable' or 'set cpu model=vaxstation' no more segmentation faults .

I will dig into it some more after the work on the 'file open error' .

Twyl , JimL

Hi James,

What Linux distribution are you working on? If you've got specific input
that causes segfaults, then that will be fixed as soon as a reproducible
case is available.

Slackware 14.2 64bit . In my case just using both of

SET CPU MODEL=VAXStation
SET GVSS ENABLE

Which causes the Segfault . Either one seperately there is no SegFault
and most every but 'boot cpu' works . But that is another story . Which I have
not had time to diagnose as of now . Will try strace of running process and see
what happens .
