155b02a089 Merge pull request #3 from livingcomputermuseum/master 
Fixes for MSCP with new DMA/IRQ infrastructure
 2019-08-16 14:25:44 +02:00
Josh Dersch
6f1b476716 Cleaned up signaling of DMA/INTR completion (using pthread_cond_wait). 
Tweaked MSYN timeout value from 350ns to 400ns to compensate for timing changes
with latest PRU code -- MSCP works reliably on PDP-11/84 again.

073a2334b6 Fixes for MSCP after Joerg's INTR/DMA rewrites: 
- Fixed programmable interrupt vector (was broken after changes)
- Fixed interrupts during MSCP 4-stage init to atomically update SA register; 4.3bsd now boots.

10cf1598f1 Big summer rework: 
Interrupt and DMA system now handles multiple levels and multiple devices in parallel
Interrupt Register changes synced with INTR transaction
DL11 and KW11 clock pass the ZDLDI0 diagnostic.
Devices can now be enabled and disabled individually.
