- using in tcl 8.6 a timed `after` together with `tclreadline` injects
spurious text of the form `after#nnn` into the readline input buffer.
- the `rw11/shell` overloads `unknown`, inviting for a bloody HACK which
simply checks for such prefixes, scrubs them, and retries the command.
- 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!)
- tools/tcl/rw11/shell.tcl
- rename all command, add leading '.' to guarantee uniqueness
- add .csus,.csto,.cres,.csta: suspend, stop, reset and start CPU
- add .cme,.cmd,.cml: enable, disable and list cpu monitor (dmcmon)
- add .ime,.imd,.imf,iml: enable, diable, setup filter and list ibus monitor
- add ?m,?u: show mmu and ubmap status
- add .hr: help on registers
- improve buildin help, better .h and additional .ha (for aspec's)
- redo ^D,.q..qq logic (assuming that it's default shell in ti_w11)
- tools/tcl
- ibd_ibmon/util.tcl: add proc filter
- rw11/dmcmon.tcl: cm_print: protect against empty lists
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
divisor or quotient were the largest negative integer (100000 or -32768).
This is corrected now, for details see ECO-026-div.txt
- some minor updates and fixes to support scripts
- xtwi usage and XTWI_PATH setup explained in INSTALL.txt
- 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
- 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
- new C++ and Tcl based backend server supports now RK11 handling
- w11a systems operate with rlink over USB on nexsy2 and nexsy3 boards.
See w11a_os_guide.txt for details
