System Debug Command Specifications Fx-LOG
INITxx
DAT when a dump is corrupted. The command is also provided for the experienced Debug
user.
For the INITNM command, the NM register set is loaded from the specified location. It is
assumed that the location contains data in the form of an interrupt stack marker (ISM)
which is the default, or in the form of processor internal memory (PIM). Not all of the
machine's registers are found in an ISM. If this is the structure being used, those registers
not stored in the ISM are retrieved from the save state area in the dump (or from the
running machine in Debug).
For the INITCM command, the CM register set is loaded from one of several locations
depending upon the option specified. Four possibilities exist:
• The emulator/translator is not running, and the CM state for the process is stored in
the CMGLOBALS area of the PIB. The CMG option is used in this case.
• The emulator/translator is running, in which case the CM state is maintained in the
native mode registers. In this case the virtual address of an interrupt stack marker
(ISM) or processor internal memory record (PIM) containing the emulator/translator's
native mode register set should be given so that the CM state may be extracted from the
registers.
• The state of the emulator/translator is stored in the task control block (TCB). As in the
PIM and ISM case above, the register data found is used to set up the CM state.
• The user desires to construct the CM state from scratch. To do this, the user must place
into the current NM register set (using the MR command) values that correspond to the
state of an active emulator/translator. The appropriate values are then extracted from
the register set to build the CM state. The REGS options allows this to be done.
Parameters
virtaddr Any valid expression specifying the virtual address of an interrupt stack
marker (ISM) or a processor internal memory (PIM) record. The type of
structure is indicated by one of the following optional parameters:
ISM The data is an interrupt stack marker (default).
PIMVIRTUAL The data is processor internal memory format.
PIMREAL The data is processor internal memory format, but the
address is a real memory address. If a full virtual address
is given, the offset part is used as the real memory
address.
TCB This parameter indicates that the register save state in the task control
block (TCB) for the current PIN should be used for initialization. The
register save state in the TCB is in the form of an
interrupt_marker_type .
CMG This parameter indicates that the CM registers should be initialized based
on CMGLOBALS area in the process information block (PIB) of the
current process.
REGS This parameter indicates that the CM registers should be initialized based
