BAD144 info was written correctly if the user answered Y when the disk
image was created, but would not work if SET RPn BADBLOCK was
entered later.
Auto sizing would be potentially wrong if a disk had been created
without writing the BAD144 data. Now, if the disk contains a file system
that information along with the physical container's size is used to
properly auto size the disk.
This allows a device simulator to specifically name the units that it uses
for different purposes. This info is visible in the output of SHOW QUEUE
and debug output.
Once specified or dynamically determined (as previously occurred with
each call to sim_uname()), that name is saved for fast delivery on subsequent
calls. This will remove some overhead when running with debugging on.
Make REM-CON units dynamically allocated and use symbolic names for the
respective different roles they play. This will make interpreting the existing
code easier and ease future extensions.
The original model started with two array variables each with one element
for each potential concurrent remote console. As functionality was added
the number of arrays grew to an unreasonable number. This change
merely gets rid of the separate arrays of per connection info and uses a
single array of REMOTE struct which contains all the per connection info.
This will make future functional extensions much cleaner.
Adds:
1) Simulator side execution of register update activities at an interval
specified in usecs. Rates in excess of 1000Hz should be achievable
for locally connected frontpanel applications.
2) New API for simulators to describe the register state available in
the simulator. If all of a the state which is potentially interesting
to front panel applications is always present in the variables
described by simh REG structures, then frontpanel API access to
that data can be more efficiently provided.
As discussed in #378
The fixes include:
1. Tightening up the "magic" code so that it can now tell EXE, SAV, and RIM
formats apart.
2. Skipping the loader itself for both RIM10B and ITS RIM. (PDP10 Macro manual
says that RIM10B always includes the loader.) 3. Distinguishing ITS RIM from
RIM10B by the length of the loader block.
4. Adding the slight differences in processing between ITS RIM and RIM10B.
There is no documentation change. -R or the extension .RIM still invoke the
RIM loader, and the code tells ITS and RIM10B apart.
The fprintf substitute function Fprintf can call tmxr_linemsgvf which may
internally produce debug output thus producing an infinite recursion.
All writes to the debug file are now done by explicit calls to fwrite() OR the
Fprintf socket destination is saved and cleared during all calls to fprintf.
Add consistent debug options to track TODR activities and the values which
are set. Debug data will display the VMS time related to the values set and
read.
Added debug CHECK option to the sim_timer_activate_after() to verify
that coscheduled events actually have sim_activate_time_usecs() results
which are consistent with each other.
Additionally, coschedule tick processing now properly counts down
pending coschedule queued activities.
Previously sim_interval was adjusted by 1 plus the total number of bytes
referenced in string instructions (SCANC, SPANC, LOCC, SKPC, CMPC3,
CMPC5, MOVC3, MOVC5). Since the amount of data that a string
instruction can reference is arbitrarily large (32bit size), the adjustment
to sim_interval could be ridiculously excessive. This can result in wild
variances in clock calibration when large string data are referenced.
- Upgrade BESM6 from experimental to be included in the 'make all'
- Add imds-225 to make all
- The cdc1700 simulator is currently the only experimental simulator
This will support arbitrary location and naming of the simh submodule in the
parent repo's working directory.
It probably won't work for sub sub modules. Suggestions welcome.
a) Added sim_debug statements, formatted console messages.
b) Removed old debugging statements and redundant byte/word mask operations.
c) Added more device commands.
d) Added zx-200a and changed nulldev to return 0 vice 0xff.
e) Added commands and corrected RTYPE and RBYTE behavior so ISIS-II would boot.
f) Corrected device calls in SBC_reset, corrected get_mbyte and put_mbyte to
match control bits from ipc_cont.c.
