Great news, OSX is now idling at 15-20%.. It's certainly an improvement.
 I'll up a patch that combines the regression (OLDVMS) and includes the
vaxidle patch.

Was this with or without the other vax idle patch (correcting interaction

Well getting back to the start of the thread, what I've done here is
regressed the idle code to include an "OLDVMS" option which set the idle
timings and hook to the old pre 3.8-1 levels, allowing things like 4.2 BSD,
and other BSD's to idle correctly.

Note that this is *FAR* from tested, as I just built it under MinGW and
booted up the NetBSD 5.0.2 miniroot, and as soon as it's done it's thing
it'll idle on my laptop (windows 7 , x64) at 0%

The patch is here:

https://sourceforge.net/projects/simh/files/Unofficial%20Patches/3.8.1/regressed-vax-idle.zip/download

Although I can verify that it seems to 'work' right on windows, when I
compile the same patch on OSX I get 50% cpu utilization

Oh well I guess it's worth something.

Re: [Simh] NetBSD5.0.2

[Nigel Horne]

Got it!  I didn't realise that the NETBSD in the set cpu idle command 
had to be in upper-case.  I "set cpu idle=NetBSD" and of course that 
failed.  When I changed to "set cpu idle=NETBSD" is started to work.


Thanks for you patience and help (incidentally I worked it out by 
looking at the source code and spotted it does a strcmp not strcasecmp).


For what it's worth, I now have both NetBSD3.1/vax and NetBSD5.0.2/vax 
working under Simh.

I've been maintaining the sourceforge stuff... And I've been collecting
patches from people or posts, and putting them on the site, as before that
I've been providing builds for anyone outside of the linux/win32
environments.. (speaking of which work FINALLY got me some OSX access so
I'll be updating with some 10.6.3 binaries...!).

Send me what you have, and I'll add it to the sourceforge page.

Peter,

I can't get the idle detection to work - Simh hogs the CPU.  I am using "set
cpu idle=netbsd".

 

Try the simh_vax_cpu_idle patch I wrote. It is on sourceforge under the
"unofficial patches" folder.
   
Thanks for the idea.  I looked and couldn't find it.  Please could you 
supply the information I need to find the patch?  I looked at 
https://sourceforge.net/projects/simh/ and then did a "Code->Browse 
CVS". There are a lot of directories there - which one contains your 
"unofficial patches"?

Are you using the networked version?

Networked version of what: Simh or NetBSD?  What do you mean by 
"networked version"?


I did and had no problems whatsoever until I had to choose the 
installation drive, but I figured that out fairly easily with a bit of 
trial and error.  If you finally get to that point and need help let 
me know.




As mentioned yesterday, doing an upgrade, rather than a re-installation, 
fixed it.

Re: [Simh] NetBSD5.0.2

[Nigel Horne]

 Deborah,

Thank you for your message.

Are you giving the emulator enough memory? NetBSD is growing. "set cpu 512m"
I tried a different approach - I copied the hard disc image and tried an 
upgrade.  I had a few errors to do with groups, but basically it worked 
and I now have NetBSD/Vax 5.0.2 working.  I am hoping that Perl works 
better than it did running 3.1 - it kept core dumping on that (I have no 
idea if the problem was with Perl, the compiler that built Perl, with 
NetBSD, with Simh or any combination of the above).


I am running with 64MB of RAM to the guest VAX, perhaps I should up that.

Having said that, thanks so much for the boot script, I will give that a 
go and keep you informed
