- the w11a rbus interface used so far a narrow dynamically adjusted
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. |

- migrate to rlink protocol version 4
- 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

- interim release w11a_V0.581 (untagged)
- new reference system
- switched from ISE 13.3 to 14.7.
- map/par behaviour changed, unfortunately unfavorably for w11a.
On Nexys3 no timing closure anymore for 80 MHz, only 72 MHz can
be achieved now.
- new man pages (in doc/man/man1/)
- support for Spartan-6 CMTs in PLL and DCM mode |
