Module
DMKEXT
Function
DMKEXT PROVIDES A CENTRAL LOCATION FOR THE PROCESSING OF
SIGNALLING REQUESTS AND MULTI-PROCESSING TYPE INTERRUPTS.
ALL SIGNALLING (EXCEPT IN DMKCPI AND DMKAPI, INITIALIZATION
ROUTINES) IS DONE THROUGH THE SIGNAL MACRO, WHICH SENDS THE
REQUEST TO DMKEXTSP SO THAT ERROR ANALYSIS AND RECOVERY
ATTEMPTS CAN BE CENTRALIZED. SO THAT THE HANDLING OF MULTI-
PROCESSING TYPE INTERRUPTS CAN ALSO BE CENTRALIZED, THE
EXTERNAL INTERRUPT SLIH (DMKPSAEX) WILL GOTO DMKEXTSL FOR ANY
TOD SYNC CHECK, EMERGENCY SIGNAL, EXTERNAL CALL, OR
MALFUNCTION ALERT.
