VAX tests?

[Teal deer: I'm looking for generic any-VAX MMU-hardware test code.] Some of you may recall that I've mentioned, a few times, that I've got a MicroVAX-II emulator I've been working on. I think it's most of the way there - seems to me I'm into the last 10% of the work which takes the second 90% of the time. :-) But when I netboot NetBSD and start to run it diskless, I get peculiar crashes which make me think I'm mis-emulating the MMU somehow. Basic operation seems to work fine - cd, ls, and the like - but under conditions the details of which I haven't pinned down yet, I get crashes like pid 65 (install), uid 0: exited on signal 11 (core not dumped, err = 14) panic: pmap_protect: outside P0LR Stopped in install at _pmap_protect+0xdf: movl $15, r8 db> I can reproduce it relatively reliably, but it takes about five minutes to do so. I'm trying to reduce the test case to something a bit more manageable, but, in the meantime, I also thought it might be worth asking after possible thorough test code. I have some test code, but it seems to be for bigger machines - 780, 8600, and the like. I searched for KA630 and I searched for MicroVAX (case-insensitive); the former gave no hits and the latter only two. One MicroVAX hit was a message in one test saying H-Floating instructions are not part of the MicroVAX instruction set, therefore tests 71 - 98 are not executed. The other was in a .hlp file, describing the use of the ATTACH command: 2 MicroVax DS> ATTACH Device type? LESI Device link? HUB Device name? DAA UDAIP? 772150 [...] Collectively, these make me think the tests I have probably predate the MicroVAX-II. I'll be trying to get the diagnostic supservisor netbooted, but it doesn't look designed for netbooting, and it's not clear to me that any of the tests are sufficiently generic to be of any use here. So, while I will be pursuing this on my own, I'd be interested to hear if anyone has any test code I might be able to get my hands on that's generic (or uV2-specific) and might indicate what's wrong in a useful way. (Useful to a simulator author, that is; "PCRB L from U248 not getting to U144, or U248/U144 bad" is not useful, whereas "translation not valid fault is pushing a partially incremented PC" is useful. :-) /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mouse at rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
