2. Change Log ----------------------------------------------------------------

|
|
- trunk (2015-01-04: svn rev 28(oc) 629(wfjm); untagged w11a_V0.63) +++++++++
|
|
|
|
- Summary
|
|
- 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.
|
|
|
|
- Remarks on reference system
|
|
- still using tcl 8.5 (even though 8.6 is now default in Ub 14.04)
|
|
- don't use doxygen 1.8.8 and 1.8.9, it fails to generate vhdl docs
|
|
|
|
- New features
|
|
- new modules
|
|

|
|
- ghdl_assert_filter - filter to suppress startup warnings

|
- tbrun_tbw - wrapper for tbw based test benches
|
|
- tbrun_tbwrri - wrapper for ti_rri + tbw based test benches
|
|
- tools/src/librw11

- Rw11Cpu - add ibus address map
|
|
- tools/src/librwxxtpp
|
|
- RtclRw11CntlRK11 - add get/set for ChunkSize
|
|
- RtclRw11Cpu - add amap sub-command for ibus map access
|
|
|
|
- Resolved known issues from V0.62
|
|
- the rbus monitor (rbd_rbmon) has been updated to handle 16 bit addresses
|
|
|
|
- Known issues
|
|
- (V0.62): rlink v4 error recovery not yet implemented, will crash on error
|
|
- (V0.62): command lists aren't split to fit in retransmit buffer size
|
|
{both issues not relevant for w11 backend over USB usage because the
|
|
backend produces proper command lists and the USB channel is error free}
|
|
