Hercules Version 3: System Messages: CP - CPU Emulation

This page describes the CPU emulation messages for the Hercules S/370, ESA/390, and z/Architecture emulator.

Messages

HHCCP001W CPU thread set priority priority failed: error
Meaning
An attempt to change the priority of the CPU thread to priority failed. The error is described by error. The thread priority has not been changed. Hercules overall performance may be impaired as a result.
Action
If performance problems are noted, correct the error and restart Hercules.
Issued by
cpu.c, function cpu_thread
HHCCP002I CPUnumber thread started: tid=threadid, pid=processid, priority=priority
Meaning
The execution thread for CPU number number has been started. Its thread id is threadid, its process id is processid, and its execution priority is priority.
Issued by
cpu.c, function cpu_thread
HHCCP003I CPUnumber architecture mode mode
Meaning
CPU number has been set to the mode architecture mode.
Action
If a different architecture mode is desired, it may be changed with the ARCHMODE configuration statement or the archmode control panel command.
Issued by
cpu.c, function cpu_thread
HHCCP004I CPUnumber Vector Facility online
Meaning
The Vector Facility for CPU number is online and available for use.
Issued by
cpu.c, function cpu_thread
HHCCP005E CPUnumber thread already started
Meaning
An attempt was made to add CPU number number to the configuration. This CPU already exists.
Action
If another CPU is desired in the configuration, select a different number.
Issued by
cpu.c, function cpu_thread
HHCCP006S Cannot create timer thread: error
Meaning
An attempt to create the thread used for timing functions has failed. The error is described by error. The CPU thread terminates and successful continuation of Hercules is not possible.
Action
Correct the error and restart Hercules.
Issued by
cpu.c, function cpu_thread
HHCCP007I CPUnumber architecture mode set to mode
Meaning
CPU number number has been changed to the architecture mode mode.
Issued by
cpu.c, function cpu_thread
HHCCP008I CPUnumber thread ended: tid=threadid, pid=processid
Meaning
The execution thread for CPU number number has ended. Its thread id was threadid, and its process id was processid.
Issued by
cpu.c, function cpu_thread
HHCCP009E CPU MASK MISMATCH: prevmask - currmask. Last instruction: instruction.
Meaning
The CPU interrupt mask has changed unexpectedly. The previous mask was prevmask, and the current mask is currmask. The last instruction executed was instruction. This is an internal error.
Action
Report this message and the circumstances to the Hercules developers.
Issued by
cpu.c, function process_interrupt
HHCCP010I CPUnumber store status completed.
Meaning
CPU number number has completed a store status operation.
Issued by
cpu.c, function process_interrupt
HHCCP011I CPUnumber: Disabled wait state
Meaning
CPU number number has entered a disabled wait state. It will not execute any further instructions unless it is reset or restarted. This is usually done to report a severe error in execution of an operating system.
Action
Correct the error denoted by the wait state code, if applicable.
Issued by
cpu.c, function process_interrupt
HHCCP023I External interrupt: Interrupt key
Meaning
The CPU has taken an external interrupt because the operator pressed the interrupt key or issued the panel command ext.
Action
None.
Issued by
external.c, function perform_external_interrupt
HHCCP024I External interrupt: Clock comparator
Meaning
The CPU has taken a clock comparator interrupt. This message is issued only when the CPU is in single-stepping or instruction-tracing mode.
Action
None. External interrupts are part of normal system operation.
Issued by
external.c, function perform_external_interrupt
HHCCP025I External interrupt: CPU timer=xx...xx
Meaning
The CPU has taken a CPU timer interrupt. xx...xx is the hexadecimal value of the CPU timer. This message is issued only when the CPU is in single-stepping or instruction-tracing mode.
Action
None. External interrupts are part of normal system operation.
Issued by
external.c, function perform_external_interrupt
HHCCP026I External interrupt: Interval timer
Meaning
The CPU has taken an external interrupt caused by the interval timer. This message is issued only when the CPU is in single-stepping or instruction-tracing mode.
Action
None. External interrupts are part of normal system operation.
Issued by
external.c, function perform_external_interrupt
HHCCP027I External interrupt: Service signal intparm
Meaning
The CPU has taken a service signal external interrupt. intparm is the interrupt parameter. This message is issued only when the CPU is in single-stepping or instruction-tracing mode.
Action
None. External interrupts are part of normal system operation.
Issued by
external.c, function perform_external_interrupt
HHCCP090W The configuration has been placed into a system check-stop state because of an incompatible service call
Meaning
A READ SCP INFO (code X'00020001') Service call has been issued from a CPU which is not a CP engine. All the CPUs in the configuration are put into a Check-Stop state.
Action
Ensure the CPU that issues the service call is a CP engine and restart the program.
Issued by
service.c, function service_call
