General cleanup: Refactored ONLINE / SET UNIT CHARACTERISTICS code, added comment headers to most functions.
...
Fixed RK05 to properly use on_param_changed instead of ugly hacks for the image path.

Fixed Unit and Controller ID fields (word order was scrambled) and removed hacked-in constant values for same.
...
Made RCT table size dynamic based on the drive type.
The above allow RSTS/E to boot! Huzzah!

Cleaned up a few things:
...
- Removed delay in mscp server polling loop, which as I suspected was papering over an issue.
We now pull all messages from the command ring at once and save them locally. When processing
completes, the polling loop goes back to sleep. This jibes with host code expectations of the
port. No more delay necessary to avoid race conditions.
- Cleaned up RCT/RBN information so that this can be dynamically configured in the future, should
the need arise

Changed reset behavior; now done asynchronously. (Was taking too long, especially during resets due to IP regsister read).
...
RSX-11M now boots and runs.

Workaround for low-level DMA issue; give up waiting for DMA transfers if enough time passes.
...
This works around an as-yet-unexplained PRU bug.

Implemented the last few unimplemented MSCP commands; as yet untested with real PDP-11/VAX code (have yet to find a case that uses them.)
...
General code cleanup/refactoring. Added header comments.
Added "use image size" parameter for MSCP disks -- block count derived from image file size rather than DEC drive geometry; allows for arbitrarily large disks (up to 2TB, theoretically.)

Fixed UDA reset behavior, a few things were not getting re-initialized. Adjusted timings. 2.11bsd boots/runs without
...
apparent issues on 11/84. Tested RT-11 on 11/84 and 11/05, mini-unix on 11/05.

Implemented AVAILABLE, ERASE, DETERMINE ACCESS PATHS commands. Tweaks to interrupt queueing (request_INTR now blocks until
...
the interrupt actually gets signaled on the unibus). OpenVMS 7.3 now boots on the VAX.

Rewrote lower-level DMA and IRQ handling: DMA and IRQ requests are now queued and will run to completion on their own
...
without help from the device code (just call request_DMA and when it returns the DMA transfer is complete.) Fixed
request_DMA to chunk DMA transfers larger than 1024 bytes to avoid overrunning the mailbox's shared memory. Fixed
concurrency issues with DMA requests -- a race condition could cause DMA request data to get clobbered.
RT-11 now boots, MSCP behavior is now very reliable.

Changes to MSCP implementation with tweaks to PRU1 code to allow operation on 11/84 under 2.11BSD.
...
2.11BSD boots and works well enough to recompile itself.

Initial stab at MSCP implementation. Strives to be MSCP compliant but is not an emulation
...
of the UDA50 controller.
Currently works acceptably with RT-11, does not currently boot. Many holes in implementation.
