1) a RELEASE is documented (in our limited case) to be equivalent to a CLEAR not a NOP.
2) avoid setting Attention as a consequence of processing an UNLOAD command.
3) extended debugging information needed while looking for an issue which turned out to be a bug in the vax 780 Massbus interrupt triggering logic.
- Cross platform VHD differencing disk fixes (dealing with file names).
- Optimization of VHD differencing disk meta data alignment
- General cleanup and casting of pointer function arguments and assignments
scp.c, scp.h
- added sim_uname (Unit Name) API to simplify places which might want to display it (mostly debug messages).
- added support for clock co-scheduling
- added debugging to trace event queue activities
sim_defs.h
- added support for clock co-scheduling
- added support for sim_uname (Thread local storage macro)
- added support for debugging to trace event queue activities
- simplified debug code by using sim_uname
- fixed support macro for sim_is_active when asynch timers are in use
sim_rev.h
- fixed nested comments
sim_tmxr.c, sim_tmxr.h
- added support for clock co-scheduling
- simplified debug code by using sim_uname
- added support for devices which poll for output on different units
sim_timer.c, sim_timer.h
- added support for clock co-scheduling
- fixed asynchronous clock calibration to smooth out calibration adjustments
- simplified debug code by using sim_uname
- added ability (when running with asynchronous support) to explicitly disable or enable asynchronous timer support.
- changed sim_timer_inst_per_sec to return a double value since the result is always used in a double expression and integer overflow could occur under strange timing conditions
vax/vax_stddev.c
- converted from simulator specific clock co-scheduling to generic clock co-scheduling.
vax/vax_cpu.c
- added EVENT and ACTIVATE debug flag (SET CPU DEBUG=EVENT;ACTIVATE) support
pdp11/pdp11_dz.c
- converted from simulator specific clock co-scheduling to generic clock co-scheduling.
pdp11/pdp11_vh.c
- converted from simulator specific clock co-scheduling to generic clock co-scheduling.
pdp11/pdp11_xq.c
- converted from simulator specific clock co-scheduling to generic clock co-scheduling.
sim_tmxr.c
sim_defs.h
- Fixed parsing issues with NOTELNET option.
- Fixed line closing logic to drop buffered contents when line errors occur before closing link.
- Fixed logic to allow bidirectional line connections (i.e. listen=1234;connect=ip:2345 on both sides of a a virtual null modem).
pdp11_dmc.c
- Fixed DMA bug which wrote data into the wrong simulated memory address.
- Fixed incoming IP address checking.
pdp11_io_lib.c
- Added the DMC device to the autoconfigure device table
vax780_defs.h
- Added comment for DMC11
The supported boot options now are:
B XQ ; Network boot
B XQA ; equivalent
B XQA0 ; equivalent
B RQ ; Boot RQ0
B RQ0 ; equivalent
B DUA ; equivalent
B DUA0 ; equivalent
B RQn ; Boot RQn
B DUAn ; equivalent
B DUn ; equivalent
B ; Boot using boot ROM device search
Also the R5 boot options can be specified either before or after the device name and with or without the R5:
For example:
B /R5:1 XQ
B /1 XQ
B XQ /R5:1
B XQ/1
are all equivalent
pdp11_xq.c, pdp11_xq.h
- Added emulation and visibility to the LEDs which were on the physical DEQNA/DELQA network boards. "show xq: will now display the LED state in addition to the other useful things.
- Added debugging of loopback packet data
- Avoided padding on short loopback packets
- Added support for extended length loopback packets (up to 1600 bytes) which is described in the DEQNA manual and used by the MicroVAX I boot ROM. Recieve such packets with the LONG error indicator.
- Returned 'reserved' status bits as 1's in received packet status word 1.
- Added debug display of transmit and receive Buffer Descriptor List contents.
sim_ether.c, sim_ether.h
- Added support for extended/oversized packets.
