IUCV Interrupt Buffer

As an IUCV-type external interrupt occurs, CP places data in the IUCV external interrupt buffer. The data describes the type of IUCV event, and data specific to each event subtype.

For a full description, see the appropriate VM documentation.

The external interrupt is traced in the internal trace table, and the first 8 bytes of the IPARML are saved in the TTE.

The following is a list of possible IUCV interrupt codes.

IPTYPE	Interrupt Type
X’01’	-- Pending Connection
X’02’	-- Connection Complete
X’03’	-- Path has been Severed
X’04’	-- Path has been Quiesced
X’05’	-- Path has been Resumed
X’06’	-- Pending Priority Message Completion
X’07’	-- Pending Non-priority Message Completion
X’08’	-- Pending Priority Message
X’09’	-- Pending Non-priority Message
