The CFGTST register MTYPE subfield should describe the additional memory
beyond 2MB on the processor board. Previous logic attempted to describe
the total system memory and the net result didn't fit into the 3 bit field and
thus said no additional memory is present.
The consequence of this new amount of memory is that ALL of it is tested
during the power on self test and thus it takes significantly longer to get to
the >>> prompt.
As reported in #944
- Only if backing store is used (i.e. OS Agnostic mode)
- Previously this was only done on a clean simulator exit. That could
result in inconsistent timing information in operating system images vs
the saved TODR baseline data
- Always return TODR values rounded to the TODR granularity (10ms).
This avoids a potential invalid pointer dereference when formatting
the return value from sim_instr() if it is < SCPE_BASE but greater
than the previously defined static array size.sizeof
Update simh.doc to reflect this generic change.
Array REGister definitions have been made consistent by passing the
name of the array object. This allows proper sizing assessment
to occur in the register validation logic.
Some previously described array REGister initializers were not really
arrays. Some were structures and others were merely pointers to
someplace in memory that it was desirable to view as a scalar array.
Structures or other blob data should now use SAVEDATA. Virtual
arrays intended to be interpret some part of memory as scalar data
now use VBRDATA initializers.
Programmatic interval timers are not proper candidates for calibrated
clocks since the interval values can change arbitrarily under program
control and then interfer with attempts at proper calibration.
This procedure establishes a telnet listen port solely so that the console
output traffic can be buffered (and not emitted). Since nothing will ever
connect to this port we bound it to the localhost address so that firewall
prompts aren't generated when building in a new directory.
Initialize Coverity flagged uninitialized variable references. Most/all
of these might never have actually occurred with reasonable
packet buffer descripter lists, but zero initialized values will never
hurt.
- MicroVAX I, II and 3900 don't have a DONE bit in the clock status
register, so sim_rtcn_tick_ack() wasn't being called to acknowledge
clock ticks.
- Timer catchup tick criteria didn't work unless the host had a slow
clock tick.
As discussed in #705
- Limit choices to explicitly either G-FLOAT or D-FLOAT for SET CPU INST=
- Compile in all instruction implementations and dynamically use the
enabled ones.
