35 |
|
|
- Preface
|
36 |
|
|
- resolved known issue V0.66-2: operation with multiple RP or RM disks
|
37 |
|
|
under 211bsd works now. Issue was caused by a faulty error check.
|
38 |
|
|
- resolved bug tracker issue 2015-06-06: the tm11 offline function works
|
39 |
|
|
now as expected. Issue was caused by de-referencing a null pointer.
|
40 |
|
|
- resolved bug tracker request 2015-06-05: the values returned as drive
|
41 |
|
|
serial number were interpreted by 211bsd standalone code as a signature
|
42 |
|
|
of SI drives, which made disk partitioning a bit cumbersome. Changed the
|
43 |
|
|
scheme used to generate drive serial numbers such that they never match
|
44 |
|
|
these 3rd party drive characteristics. The 211bsd installation on a
|
45 |
|
|
RM05 is documented with the 211bsd_tm oskit.
|
46 |
|
|
- the w11a designs grow larger, filling the FPGA's on Nexys2 and Nexys3
|
47 |
|
|
to ~50% (n2) or 67% (n3). To reach timing closure without fine tuning
|
48 |
|
|
constraints the cpu clock had to be reduced to
|
49 |
|
|
sys_w11a_n2 now 52 MHz (was 54 MHz)
|
50 |
|
|
sys_w11a_n3 now 64 MHz (was 68 MHz)
|
51 |
|
|
|
52 |
|
|
- w11a has now a complete set of mass storage peripherals. This is a good
|
53 |
|
|
reason of a major release, thus go for version V0.70.
|
54 |
|
|
|
55 |
|
|
- there are many known issues, and in many cases only core functionality
|
56 |
|
|
used by operating systems has been implemented. The missing parts will
|
57 |
|
|
be implemented in the upcoming releases towards V0.80, also much more
|
58 |
|
|
intensive testing, especially with maindecs (aka xxdp) will be done.

- Preface
|
88 |
|
|
|
89 |
|
|
- Since the previous release a full set of small, medium and large sized
|
90 |
|
|
disks (RK,RL,RP/RM) is available, covering all use cases. Still missing
|
91 |
|
|
was a tape system, which allows to install systems from distribution tapes
|
92 |
|
|
but is also very handy for data exchange. This release adds a TM11/TU10
|
93 |
|
|
tape controller emulation. This is much simpler to implement than a
|
94 |
|
|
massbus based TU16 or TU78 controller. Because storage is emulated there
|
95 |
|
|
is neither a speed nor a capacity advantage of 1600 or 6250 bpi drives,
|
96 |
|
|
so for all practical purposes the simple 800 bpi TU10 drive emulation is
|
97 |
|
|
fully adequate.
|
98 |
|
|
The TM11/TU10 was tested under 211bsd with creating a tape distribution
|
99 |
|
|
kit and building a RP06 based system from such a tape. A 211bsd_tm
|
100 |
|
|
oskit is provided with a recipe to restore a RP06 from tape.
|
101 |
|
|
|
102 |
|
|
- bug fixes
|
103 |
|
|
- the ti_rri event loop aborted under heavy load with three devices, seen
|
104 |
|
|
when RP disk, TM tape and DL11 run simultaneously. Was caused by a race
|
105 |
|
|
condition in attention handling and dispatching.
|
106 |
|
|
- the boot command failed when cpu was running and the unit not decoded
|
107 |
|
|
properly, so boots from units other then 0 failed.
|
108 |
|

- resolved issues: -- none --
|
147 |
|
|
- new issues:
|
148 |
|
|
- V0.66-1: the TM11 controller transfers data byte wise (all disk do it
|
149 |
|
|
16bit word wise) and allows for odd byte length transfers. Odd length
|
150 |
|
|
transfers are currently not supported and rejected as invalid command.
|
151 |
|
|
Odd byte length records aren't used by OS, if at all, so in practice
|
152 |
|
|
this limitation isn't relevant.
|
153 |
|
|
- V0.66-2: using two RP06 drives in parallel under 211bsd leads to a
|
154 |
|
|
hangup of the system after a short time. Currently only operation
|
155 |
|
|
of a single drive works reliably.

|
158 |
|
|
- Preface
|
159 |
|
|
|
160 |
|
|
- With small RK05 or RL02 sized disks only quite reduced OS setups could
|
161 |
|
|
be booted, full featured systems were beyond reach. Now finally large
|
162 |
|
|
disks are available, with a RH70 + RP/RM disk controller emulation. It
|
163 |
|
|
supports up to four disks and allows now to run full featured 211bsd
|
164 |
|
|
or rsx-11mplus systems.
|
165 |
|
|
|
166 |
|
|
- to track down issues with ibus devices a 'ibus monitor' was added, it can
|
167 |
|
|
record in the default setup up to 511 ibus transactions. An address filter
|
168 |
|
|
allows to select accesses of one device. The ibd_ibmon tcl package
|
169 |
|
|
contains the appropriate support scripts.
|
170 |
|
|
|
171 |
|
|
- several cleanups
|
172 |
|
|
- factor out common blocks on sys_w11a_* systems: the core+rbus+cache
|
173 |
|
|
logic of single cpu systems now contained in pdp11_sys70, and the
|
174 |
|
|
human I/O for digilent boards now in pdp11_hio70.
|
175 |
|
|
- cpu start/stop logic cleanup: new command set with simple commands.
|
176 |
|
|
Add also a new suspend/resume mechanism, which allows to hold the cpu
|
177 |
|
|
without leaving the 'run state'. While suspended all timers are frozen.
|
178 |
|
|
Very helpful when debugging, will be the basis for a hardware break
|
179 |
|
|
point logic in a later release.
|
180 |
|
|
- xon/xoff consolidation: escaping now done in cdata2byte/byte2cdata in
|
181 |
|
|
FPGA and in RlinkPacketBufSnd/RlinkPacketBufRcv in backend. The extra
|
182 |
|
|
escaping level in serport_xonrx/serport_xontx isn't used anymore, the
|
183 |
|
|
special code in RlinkPortTerm has been removed. This allows to use
|
184 |
|
|
xon/xoff flow control also in simulation links via RlinkPortFifo.
|
185 |
|
|
- status check cleanup: it is very helpful to have a default status check
|
186 |
|
|
and an easy way to modify it cases where some error flags are expected
|
187 |
|
|
(e.g. on device polls). In the old logic status and data checks were
|
188 |
|
|
done via RlinkCommandExpect. The new logic reflects that status checks
|
189 |
|
|
are the normal case, and store the status check pattern in RlinkCommand.
|
190 |
|
|
The meaning of expect masks for status and data is inverted, now a '1'
|
191 |
|
|
means that the bit is checked (before it meant the bit is ignored).
|
192 |
|
|
The default status check pattern is still in RlinkContext, but will be
|
193 |
|
|
copied to RlinkCommand when the list is processed. RlinkCommandExpect
|
194 |
|
|
handles now only data checks.
|
195 |
|
|
|
196 |
|
|
- and bug fixes
|
197 |
|
|
- rk11 cleanup: since the first days 211bsd autoconfig printed
|
198 |
|
|
rk ? csr 177400 vector 220 didn't interrupt
|
199 |
|
|
for boots from a RK11 it didn't have consequences, but when booted from
|
200 |
|
|
a RL,RP, or RM disk this prevents that the RK11 disks are configured.
|
201 |
|
|
Was caused by a missing interrupt after device reset. Now fixed.
|
202 |

- Preface
|
282 |
|
|
- The w11 project started on a Spartan-3 based Digilent S3board, and soon
|
283 |
|
|
moved on to a Nexys2 with much better connectivity. Next step was the
|
284 |
|
|
Spartan-6 based Nexys3. Now is time to continue with 7-Series FPGAs.
|
285 |
|
|
- When Vivado started in 2013 it was immediately clear that the architecture
|
286 |
|
|
is far superior to ISE. But tests with the first versions were sobering,
|
287 |
|
|
the w11a design either didn't compile at all, or produced faulty synthesis
|
288 |
|
|
results. In 2014 Vivado matured, and the current version 2014.4 works
|
289 |
|
|
fine with the w11a code base.
|
290 |
|
|
- The original Nexys4 board allowed to quickly port Nexys3 version because
|
291 |
|
|
both have the same memory chip. The newer Nexys4 DDR will be addressed
|
292 |
|
|
later.
|
293 |
|
|
- The BRAM capacity of FPGAs increased significantly over time. The low
|
294 |
|
|
cost Basys3 board with the second smallest Artix-7 (XC7A35T) has 200 KB
|
295 |
|
|
BRAM. That allows to implement a purely BRAM based w11a system with
|
296 |
|
|
176 kB memory. Not enough for 2.11BSD, but for many other less demanding
|
297 |
|
|
OS available for a PDP11.
|
298 |
|
|
- The Nexyx4 and Basys3 have 16 LEDs. Not quite the 'blinking lights'
|
299 |
|
|
console of the classic 11/45 and 11/70, but enough to display the
|
300 |
|
|
well known OS typical light patterns the veterans remember so well.
|
301 |
|
|
- With a new design tool, a new FPGA generation, two new boards, and a
|
302 |
|
|
new interface for the rlink connection that some of the code and tools
|
303 |
|
|
base had to be re-organized.
|
304 |
|
|
- Last but not least: finally access to a bit bigger disks: RL11 support
|
305 |
|
|
- Many changes, some known issues, some rough edges may still lurke around
|
306 |

|
401 |
|
|
- Rw11CntlRK11 - revise RdmaPostExecCB() logic
|
402 |
|
|
|
403 |
|
|
- Known issues
|
404 |
|
|
- V0.64-7: ghdl simulated OS boots via ti_w11 (-n4 ect options) fail due to
|
405 |
|
|
a flow control issue (likely since V0.63).
|
406 |
|
|
- V0.64-6: IO delays still unconstraint in vivado. All critical IOs use
|
407 |
|
|
explicitly IOB flops, thus timing well defined.
|
408 |
|
|
- V0.64-5: w11a_tb_guide.txt covers only ISE based tests (see also V0.64-4).
|
409 |
|
|
- V0.64-4: No support for the Vivado simulator (xsim) yet. With ghdl only
|
410 |
|
|
functional simulations, post synthesis (_ssim) fails to compile.
|
411 |
|
|
- V0.64-3: Highest baud rate with basys3 and nexys4 is 10 MBaud. 10 MBaud
|
412 |
|
|
is not supported according to FTDI, but works. 12 MBaud in next release.
|
413 |
|
|
- V0.64-2: rlink throughput on basys3/nexys4 limited by serial port stack
|
414 |
|
|
round trip times. Will be overcome by libusb based custom driver.
|
415 |
|
|
- V0.64-1: The large default transfer size for disk accesses leads to bad
|
416 |
|
|
throughput in the DL11 emulation for low speed links, like the
|
417 |
|
|
460kBaud the S3board is limited too. Will be overcome by a DL11
|
418 |
|
|
controller with more buffering.
|
419 |
|
|
- V0.62-2: rlink v4 error recovery not yet implemented, will crash on error
|
420 |
|
|
- V0.62-1: Command lists aren't split to fit in retransmit buffer size
|
421 |
|
|
{last two issues not relevant for w11 backend over USB usage because
|
422 |
|
|
the backend produces proper command lists and the USB channel is
|
423 |
|
|
usually error free}

426 |
|

|
427 |
|
|
- Summary
|
428 |
|
|
- the w11a rbus interface used so far a narrow dynamically adjusted
|
429 |
|
|
rbus->ibus window. Replaces with a 4k word window for whole IO page.
|
430 |
|
|
- utilize rlink protocol version 4 features in w11a backend
|
431 |
|
|
- use attn notifies to dispatch attn handlers
|
432 |
|
|
- use larger blocks (7*512 rather 1*512 bytes) for rdma transfers
|
433 |
|
|
- use labo and merge csr updates with last block transfer
|
434 |
|
|
- this combined reduces the number of round trips by a factor 2 to 3,
|
435 |
|
|
and in some cases the throughput accordingly.

The development and test system was upgraded from Kubuntu 12.04 to 14.04.
|
502 |
|
|
The version of several key tools and libraries changed:
|
503 |
|
|

libusb 1.0.17 (was 1.0.9)
|
507 |
|
|
perl 5.18.2 (was 5.14.2)
|
508 |
|
|
tcl 8.5.15 (was 8.5.11)
|
509 |
|
|
sdcc 3.3.0 (was 2.9.0)
|
510 |

|
555 |
|
|
- command lists aren't split to fit in retransmit buffer size

557 |
|
|
backend produces proper command lists and the USB channel is error free}
|
558 |
|
|
- the rbus monitor (rbd_rbmon) not yet handling 16 bit addresses and
|
559 |
|
|
therefore of limited use
