PDP10, PDP11, Unibus VAXen: Add auto configure support for CH11 #2

Closed markpizz closed 6 years ago

This will set address and vector for the CH11.

Great, thanks! Good timing, I was just wondering how this should be done.

Still wondering how it should be done...

With your patch applied, I see this:

VAX 11/780 simulator V4.0-0 Current        git commit id: 30aecb29
sim> set ch enabled
sim> show ch
CH      address=2013E860-2013E867, vector=B8, BR5
        not attached
sim> set ch address=2013E860
Non-existent parameter

And when I boot 4.1BSD with Chaosnet patches applied, I get this:

chch0 at uba0 csr 164140 didn't interrupt

Never mind! I see now hardware register accesses are coming through.
