You paged??? I've been flat out lately. Sorry.
What's up? I will be around all day today.
I needed to bother you about a couple of things:
My Multinet tunnel to your network has died unrecoverable (or so I can see).
I am gearing up to start work on a VMS cluster and need some tips and tuition.
I'll be around for a while tonight.

Silly question, but is "set cpu idle" actually the first thing in your ini
file? Can you post the whole ini file?
I'd have to check, but if I just run it with no ini file I still get that issue (and this is on latest and greatest Sol 11)

That's odd. I just downloaded and built simh 3.9.0, and it accepts the command without any complaints, both in "vax" and "vax780":

Yeah, works fine on linux, but Solaris not so much. :(
And now libpcap doesn't want to easily build on newest Solaris 11. Joy.

You mean it doesn't? I wonder why that would be.

It detects the idle loop patterns in some OSs and throttles back the
simulator, so the host system isn't sitting there burning CPU to execute
the guest OS's idle loop.
Right, but I'm curious what it needs to know about the host OS to accomplish that.
I should look at the source but I'm not sure I'll know what I'm looking at. :)
See vax_cpu.c.
My copy (SIMH 3.8.1) rejects that command with a different message: "Invalid argument". But to make things even stranger, it DOES accept the command -- "show cpu idle" shows that it paid attention.
Possibly the issue is that the VAX-specific command next passes control to the general command (in sim_timer.c) and that routine accepts an argument but requires it to be an integer!
You might try simply "set cpu idle" (without argument). The default seems to be VMS, with NETBSD, OPENBSD, ULTRIX, and 32V accepted as alternate values. The difference is in what the particular OS does when it is idle. That tends to change from one OS to another (even when the hardware seems to suggest a standard way to do it, as in the PDP11 with its WAIT instruction).

Same thing:

Looks like you'll have to read the Fine Code to see what changed.

Looks like there were some changes to IDLE for the VAX in 3.9
building that now.

Oh my. I assume that's done by a #define somewhere. Have you looked?
Yes. The code is a little.............. tricky to follow.
I don't think I'm going to be able to sort this out. I just don't have the time it'll take to go through all his code. :(
