From mboxrd@z Thu Jan 1 00:00:00 1970 From: bill@cs.scranton.edu (Bill Gunshannon) Date: Thu, 22 Feb 2001 15:02:36 -0500 (EST) Subject: [pups] Stray Interupts Message-ID: The Ultrix-11 saga continues but some progress is being made. Has anyone run into a problem with stray interupts when using RP type disks with the Supnik emulator?? While I am not sure they cause any real problem, they are an annoyance and do clutter up the console terminal. May need to figure out how to come up with a remote TTY and start doing my work (especially kermiting) from there. In the meantime, I hope to have a full Ultrix-11 development system running in the next day or so. That means building all the pieces needed for a split I&D system. And now for the obligatory question: When I tried run Ultrix-11 on my 11/93 I got a message that said: "Unknown processor. enter CPU type in R0 and continue at your own risk." Anyone know where I might find these magical numbers?? I figure if I lie and tell him it's a 73 it should at least run. Yes?? No?? bill -- Bill Gunshannon | de-moc-ra-cy (di mok' ra see) n.

Are the stray interrupts being reported by the Ultrix kernel or the simulator itself. If the latter, you can always edit out the offending printfs.

The big question is, is this a problem with Ultrix or is this a problem with emulator that just gets ignored by the other OSes. I would be curious to know if there is a similar function in 2.11?? If so, it would be interesting to compare them and see why Ultrix sees all these stray interupts that no one else sees. All the best. bill -- Bill Gunshannon | de-moc-ra-cy (di mok' ra see) n.

The big question is, is this That the messages are coming from Ultrix and not the simulator is also is easily determined by grep'ing the simulator sources - no such message string that I can see. > a problem with Ultrix or is this a problem with emulator that just > gets ignored by the other OSes. I would be curious to know if there > is a similar function in 2.11?? If so, it would be interesting to There's no direct counterpart to 'logsi' in 2.11BSD. The only 'stray interrupt' messages 2.11 can produce all come out of networking drivers (the LH/DH "IMP" driver if_acc for example). The "big disk" support ('rp') was done though by Bob without access to a real honest to DEC RP11 controller. I think he looked at various driver sources and perhaps at 2.11's "xp" driver (I vaguely recall sending him the xp.c and necessary include files). > compare them and see why Ultrix sees all these stray interupts that > no one else sees. Various things suggest themself to me: It might just be that Ultrix is overly picky, there's something not 100% accurate in the simulator's delivering interrupts or Ultrix-11 has a bug. I haven't heard of RT-11 having a problem - perhaps someone could try that and see what happens. The other thing you might try is the Begemot emulator "p11". It keeps _vastly_ better time than 'sim_2.3d' and has an emulated DEQNA so the machine can be placed on a network. P11's also quite a bit more efficient/fast. Configuration can be puzzling but sample config files are available (from various PUPS folks who run P11).

Does Bob (or anybody for that matter) still maintain the emulator?? Maybe the Ultrix source would be a help in better understanding some of the internals of the hardware. > > > compare them and see why Ultrix sees all these stray interupts that > > no one else sees. > > Various things suggest themself to me: It might just be that Ultrix is > overly picky, there's something not 100% accurate in the simulator's > delivering interrupts or Ultrix-11 has a bug. My experience with Ultrix-11 up to this point would lead me to believe that it isn't bugs, but I can easily accept that it is overly picky. That's why I thought the sources might be a big help in tuning the emulator. > > I haven't heard of RT-11 having a problem - perhaps someone could > try that and see what happens. I tried RSTS. As a matter of fact, I used DSKINT to create my empty RP06 images. No sogn of a problem there. > > The other thing you might try is the Begemot emulator "p11".

I have the latest version but I have been unable to get any of my disk images to work. Can anyone tell me if you can use the disk images from the other emulators and if so, how?? Do they have to be converted somehow like tapes?? bill -- Bill Gunshannon | de-moc-ra-cy (di mok' ra see) n. Three wolves bill at cs.scranton.edu | and a sheep voting on what's for dinner.

Version 2.5a was released on January 1, and Bob recently asked me to update a pointer to his simulator web page, so I'd say he does. -- http://lars.nocrew.org/ Received: (from major at localhost) by minnie.cs.adfa.edu.au (8.9.3/8.9.3) id DAA17804 for pups-liszt; Sat, 24 Feb 2001 03:51:03 +1100 (EST) (envelope-from owner-pups at minnie.cs.adfa.edu.au) Received: from moe.2bsd.com (MOE.2BSD.COM [206.139.202.200]) by minnie.cs.adfa.edu.au (8.9.3/8.9.3) with ESMTP id DAA17791 for ; Sat, 24 Feb 2001 03:50:59 +1100 (EST) (envelope-from sms at moe.2bsd.com) Received: (from sms at localhost) by moe.2bsd.com (8.10.1/8.10.1) id f1NGgqP08664 for pups at minnie.cs.adfa.edu.au; Fri, 23 Feb 2001 08:42:52 -0800 (PST) Date: Fri, 23 Feb 2001 08:42:52 -0800 (PST) From: "Steven M.

That shows how long it has been since I ran that simulator ;-) I'll pull it in just to have the latest version around to test with. Steven Schultz sms at moe.2bsd.com
