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

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

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

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

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

|
|
|
|
- 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.

|
- New reference system
|
|
The development and test system was upgraded from Kubuntu 12.04 to 14.04.
|
|
The version of several key tools and libraries changed:
|
|
linux kernel 3.13.0 (was 3.2.0)
|
|
gcc/g++ 4.8.2 (was 4.6.3)
|
|
boost 1.54 (was 1.46.1)
|
|
libusb 1.0.17 (was 1.0.9)
|
|
perl 5.18.2 (was 5.14.2)
|
|
tcl 8.5.15 (was 8.5.11)
|
|
sdcc 3.3.0 (was 2.9.0)
|
|
doxygen 1.8.7 {installed from sources; Ub 14.04 has 1.8.6}
|
|
|
|
Notes:
|
|
1. still using tcl 8.5 (even though 8.6 is now default in Ub 14.04)
|
|
2. sdcc 3.x is not source compatible with sdcc 2.9. The Makefile
|
|
allows to use both, see tools/fx2/src/README.txt .
|
|
3. don't use doxygen 1.8.8, it fails to generate vhdl docs
|
|
|

|
- Summary
|
|
- The div instruction gave wrong results in some corner cases when either
|
|
divisor or quotient were the largest negative integer (100000 or -32768).
|
|
This is corrected now, for details see ECO-026-div.txt

|
