- dmcmon has now the sta,sto,sus,res logic as rbmon and ibmon
- dmcmon does not depend on full state number generation anymore
- dmcmon missed WAIT instructions so far, has been fixed
- related changes:
- pdp11_sequencer can now return a simple instruction type based snum
- sys_w11a_n4 includes dmcmon again (now independent of dmscnt!)
rbus->ibus window. Replaces with a 4k word window for whole IO page.
- utilize rlink protocol version 4 features in w11a backend
- use attn notifies to dispatch attn handlers
- use larger blocks (7*512 rather 1*512 bytes) for rdma transfers
- use labo and merge csr updates with last block transfer
- this combined reduces the number of round trips by a factor 2 to 3,
and in some cases the throughput accordingly.
- Goals for rlink v4
- 16 bit addresses (instead of 8 bit)
- more robust encoding, support for error recovery at transport level
- add features to reduce round trips
- improved attention handling
- new 'list abort' command
- For further details see README_Rlink_V4.txt
- use own C++ based tcl shell tclshcpp instead of tclsh
- C++ and Tcl based backend server now fully functional, supports with
DL11, RK11, LP11 and PC11 all devices available in w11a designs
- the old perl based backend server (pi_rri) is obsolete and removed
- operating system kits reorganized
