- uncalibrated clock mode executes at a precisely specified instruction
rate relative to pseudo wall clock time independent of the host
computer's speed or other loads on the host system.
- Provide additional failure state if/when diagnostics fail.
- Run Floating Instruction diagnostics for 2 passes - these have
been observed to fail on the VAX730
- Increase allowed run limit
- When diagnostics fail, emit the diagnostic session output if
diagnostics were not being run in verbose mode.
Simulators built with DONT_USE_INTERNAL_ROM defined will not have hte
binary of the needed ROM or boot components build into the simulator
binaries. However, they will automatically and transparently fetch the
neeeded ROM or boot code from the web when these binary files aren't
available locally.
- Plan is to avoid "#ifdef DONT_USE_INTERNAL_ROM" in simulator code
and handle builtin or external files in SCP facilities
- Export ROM checksum value and source file path to allow for transparent
dynamic ROM location at run time.
If autoconfigure is disabled, either explicitly or implicitly by manual
setting of an ADDRESS or VECTOR, detect devices which don't have
addresses before boot.
Historically, if a configuration file explicitly set either a DEVICE's
ADDRESS or VECTOR, autoconfiguration was immediately disabled.
This change defers disabling autoconfigure until an explicitly setting
of a DEVICE address or VECTOR actually changes what had been previously
configured by autoconfigure.
These devices start disabled and will be that way in essentially all
working systems, but there apparently was a DECnet Phase V
support for this device, so it is added to all systems. The DPV
should now be readily testable.
As mentioned in #1152. That PR will fix the DUP device.
The actual contents of the input ROM binary files and the contents of the
created arrays are unchanged.
Multiple ROM image include files can be included in the same source module
without the need for any #undef BOOT_CODE_SIZE, etc.
Historically this functionality was reimplemented within each
DEVICE simulator often with slightly different implementations
and inconsistencies. Solving this globally within SCP required
changes in many places, but should henceforth be reasonably
managed.
As discussed in #1034
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.
