/* System power state.
The HP 3000 power supply uses two signals to indicate its state: PON (power
on) and PFW (power-fail warning). PON is asserted when the DC power levels
are within their operating ranges. PFW is asserted when AC power is lost.
When a power failure occurs, PFW will be asserted at least three milliseconds
before PON is denied. When power is restored, PFW denies immediately, but
PON does not assert until the DC output voltages have stabilized, and the
machine is ready to resume execution.
In simulation, the four states of these two signals are modeled with
enumeration constants, as follows:
PON PFW State Simulator Action

3. The CMD instruction is simulated by assuming that the addressed module
will send a return message to the CPU, causing a module interrupt. If
the module is the CPU, then the "return message" is the originating
message, including whatever MOP was specified. Memory modules return a
no-operation MOP in response to a read or read/write ones MOP. Sending a
read/write ones MOP to a Series II memory module sets the addressed
location to 177777 before the read value is returned.
4. The module interrupt signal is qualified by the I-bit of the status
register. This is simulated by setting the cpx1_MODINTR bit in the CMD
executor if the I-bit is set, by clearing the cpx1_MODINTR bit in the SED
0 executor, and by setting the bit in the SED 1 executor if the MOD
register is non-zero (indicating a pending module interrupt that has not
been serviced).

/* Device reset routine.
This routine is called for a RESET or RESET IOP command. It is the
simulation equivalent of the IORESET signal, which is asserted by the front
panel LOAD and DUMP switches.
Implementation notes:
1. In hardware, IORESET clears flip-flops associated with the state machines
that implement the interrupt poll, SO/SI handshake, and multiplexer
channel access. In simulation, these are all represented by function
calls and, as such, are atomic. Therefore, the only state variable that
IORESET clears is the external interrupt flip-flop, which is implemented
as its respective bit in the CPX1 register rather than as a separate
variable. Setting IOA to 0 and calling iop_initialize clears this bit;
it also sets up the devs array, which is used by the POWER FAIL command.
2. In hardware, IORESET also clears the IOP address parity error, system
parity error, and illegal address flip-flops. However, these exist only
to assert XFERERROR to devices. In simulation, XFERERROR is sent to a
device interface when the initiating condition is detected by the
multiplexer channel, so these are not represented by state variables.

width and offset fields are changed with the printer model to reflect the
number of VFU channels available, and the depth field is changed by the
VFU load routine to reflect the number of lines defined for the current
form. This allows an "EXAMINE LP VFU[ALL]" command to display the
current number of channels and lines.
2. The VFUREG register must immediately precede the VFU register. The
location field is changed at power-on reset to point at the VFU register
entry. This ensures that the full REG structure for the VFU register is
SAVEd and RESTOREd properly, which is necessary for the dynamic VFU

=====================
Release 3, 2016-09-20
=====================
This release of the HP 3000 simulator adds the following features:
- Cold dump is now available. Entering the DUMP command simulates pressing
the ENABLE and DUMP front panel buttons. The contents of main memory are
written to an attached magnetic tape in a format suitable for analyzing with
the DPAN4 program. The new SET CPU DUMPDEV and SET CPU DUMPCTL options
specify the default device number and control byte for the dump.
- The SHOW LP VFU command now displays the VFU channel definitions in
addition to the VFU tape title.
- The POWER FAIL and POWER RESTORE commands have been added to simulate losing
and regaining system power.
- The SET CPU ARS and SET CPU NOARS options have been added to simulate the
power-fail/auto-restart switch on the back of the system front panel.
- The CMD instruction has been implemented and passes section 4 of the CPU
diagnostic.
--------------------
Implementation Notes
--------------------
- In hardware, MPE execution cannot continue after a DUMP is performed. This
is because a cold dump performs an I/O reset before writing the contents of
memory to the tape, and this clears the I/O device controllers to their
initial power-on states. However, execution can be continued if a SAVE is
done to record the simulator state before the dump and a RESTORE is done
after the dump completes. This permits taking a "snapshot" of MPE operation
without disturbing MPE.
----------
Bugs Fixed
----------
1. PROBLEM: An SIO READ or WRITE order with a 4K count displays as zero.
VERSION: Release 2
OBSERVATION: SIO READ and WRITE orders define bits 4-15 as the negative
word count of the transfer. If bits 4-15 are zero, the transfer is 4096
words long. However, an EXAMINE -I command displays the word count as
zero.
CAUSE: The display value is being calculated incorrectly.
RESOLUTION: Modify "IOCW_COUNT" (hp3000_cpu_ims.h) to sign-extend the
12-bit count correctly to 16 bits, and modify "fprint_order" (hp3000_sys.c)
to negate the values to display the counts as positive. Also modify
"mpx_interface" (hp3000_mpx.c) to display the correct count in the debug
trace for the DREADSTB operation.
STATUS: Fixed in Release 3.
2. PROBLEM: An I/O reset does not clear a pending external interrupt.
VERSION: Release 2
OBSERVATION: A cold load begins with a CPU reset and an I/O reset. A cold
dump begins with an I/O reset only to preserve the CPU state for the dump
operation. The external interrupt flip-flop on the IOP is cleared by an
I/O reset, which should clear the external interrupt bit in the CPX1
register. However, this does not occur, causing the interrupt generated by
placing the tape drive online to be misinterpreted as the SIO program
completion interrupt. Because the SIO pointer is not set as expected, the
cold dump microcode assumes that a tape error occurred and performs a
retry. This writes an erase gap at the beginning of the tape but otherwise
produces a valid tape.
CAUSE: Oversight.
RESOLUTION: Add a new "iop_reset" routine (hp3000_iop.c) that is called
during an I/O reset and that clears the external interrupt bit of the CPX1
register.
STATUS: Fixed in Release 3.
3. PROBLEM: RESTORE of a file SAVEd with a different executable may abort the
simulator.
VERSION: Release 2
OBSERVATION: Entering SAVE to save the simulator state on an executable
compiled with one set of compiler options or compiler version and then
entering RESTORE to restore the state on an executable compiled with a
different set of compiler options or compiler version succeeds. However,
attempting to resume execution results in an access exception.
CAUSE: The simulator's internal Device Information Blocks contain pointers
to the devices' I/O interface handlers, which are saved as part of the DIB
structure in the simulator state file. When restoring the state, the
interface handler pointers are restored. However, the addresses of one or
more routines may have changed, due to differing memory layouts, so the
restored values are no longer correct. If they are not, and I/O is
performed to the affected device(s), control transfers to an invalid code
location.
RESOLUTION: Modify hp3000_io.h to add a new REG_DIB macro that defines the
register entries needed to save the DIB state, and modify hp3000_atc.c,
hp3000_clk.c, hp3000_ds.c, hp3000_lp.c, hp3000_mpx.c, hp3000_ms.c, and
hp3000_scmb.c to change the REG entries referencing the DIB structures to
use the REG_DIB macro.
STATUS: Fixed in Release 3.
4. PROBLEM: The LOAD command does not report "Cold load complete".
VERSION: Release 2
OBSERVATION: The LOAD command should report success after completion of a
cold load operation, but it doesn't. Instead, the SCP prompt returns with
no indication of whether the command succeeded or failed. Using the
equivalent BOOT CPU command does print the expected "Cold load complete"
message.
CAUSE: The "Cold load complete" message is printed by the simulator's
"fprint_stopped" routine that is called via the "sim_vm_fprint_stopped"
pointer from the "run_cmd_message" routine in SCP. The latter is invoked
via the "message" field of the command table. The LOAD, DUMP, and POWER
commands all invoke "sim_instr" via "run_cmd" but do not specify routine
pointers for their message fields, so no completion messages are reported.
RESOLUTION: Modify "one_time_init" (hp3000_sys.c) to set the "message"
fields of the LOAD, DUMP, and POWER commands to point at the same routine
as is used by the system "CONTINUE" command.
STATUS: Fixed in Release 3.
5. PROBLEM: RESTOREing with the ATCD attached cancels active line services.
VERSION: Release 2
OBSERVATION: Doing a SAVE while the ATCD has line services scheduled,
e.g., while outputting characters, and then following immediately with a
RESTORE cancels the line services. For example, after a SAVE, a SHOW QUEUE
command prints:
HP 3000 event queue status, time = 907247803
CLK at 0
ATCD unit 0 at 241
CPU at 27917
ATCD unit 16 at 27918
DS unit 8 at 612615
Entering RESTORE and then SHOW QUEUE prints:
HP 3000 event queue status, time = 907247803
CLK at 0
CPU at 27917
ATCD unit 16 at 27918
DS unit 8 at 612615
Note that ATCD unit 0 is no longer scheduled.
CAUSE: The "atcd_detach" routine is called during RESTORE if the listening
port is currently attached in preparation for reattaching to the port
specified in the SAVE file. The routine detaches the listening port and
then cancels each line to terminate any transfers in progress. This is
appropriate for DETACH ATCD and DETACH ALL, but not for RESTORE, as the
terminal channels have already been rescheduled as indicated in the SAVE
file, and canceling them hangs the channels.
RESOLUTION: Modify "atcd_detach" (hp3000_atc.c) to skip the channel
termination loop if the SIM_SW_REST flag is set to indicate a RESTORE in
progress.
STATUS: Fixed in Release 3.

2. The routine returns a pointer to a static buffer containing the printable

the null-terminated format strings are concatenated in the buffer, and
each call returns a pointer that is offset into the buffer to point at
the latest formatted string.
3. There is no explicit buffer-free action. Instead, newly formatted
strings are appended to the buffer until there is no more space
available. At that point, the pointers are reset to the start of the
buffer. In effect, this provides a circular buffer, as previously
formatted strings are overwritten by subsequent calls.

Implementation notes: Implementation notes:
1. The routine returns a pointer to a static buffer containing the printable 1. The routine returns a pointer to a static buffer containing the printable
string, so it cannot be called more than once per trace line, unless the string. To allow the routine to be called more than once per trace line,
buffer contents are copied upon return. In particular, this type of the null-terminated format strings are concatenated in the buffer, and
calling sequence: each call returns a pointer that is offset into the buffer to point at
the latest formatted string.
dprintf (..., fmt_bitset (...), ..., fmt_bitset (...), ...); 2. There is no explicit buffer-free action. Instead, newly formatted
strings are appended to the buffer until there is no more space
available. At that point, the string currently being assembled is moved
to the start of the buffer, and the pointers are reset. In effect, this
provides a circular buffer, as previously formatted strings are
overwritten by subsequent calls.
...will fail, as the buffer will be overwritten by the second call before 3. The buffer is sized to hold the maximum number of concurrent strings
the result of the first call is printed. needed for a single trace line. If more concurrent strings are used, one
or more strings from the earliest calls will be overwritten. If an
attempt is made to format a string larger than the buffer, an error
indication string is returned.
4. The location of the end of the buffer used to determine if the next name
will fit includes an allowance for two separators that might be placed on
either side of the name and a terminating NUL character.

/* Execute the LOAD and DUMP commands.
This routine implements the cold load and cold dump commands. The syntax is:
LOAD { <control/devno> }
DUMP { <control/devno> }
The <control/devno> is a number that is deposited into the SWCH register
before invoking the CPU cold load or cold dump facility. The CPU radix is
used to interpret the number; it defaults to octal. If the number is
omitted, the SWCH register value is not altered before loading or dumping.
On entry, the "arg" parameter is "Cold_Load" for a LOAD command and
"Cold_Dump" for a DUMP command, and "buf" points at the remainder of the
command line. If characters exist on the command line, they are parsed,
converted to a numeric value, and stored in the SWCH register. Then the
CPU's cold load/dump routine is called to set up the CPU state. Finally, the
CPU is started to begin the requested action.
Implementation notes:
1. The run command invocation prepares the simulator for execution, which
includes a CPU and I/O reset. However, the cpu_reset routine does not
reset the CPU state if the cold dump switch is set. This allows the
value of the CPX2 register to be saved as part of the dump.
