Abstract
A method and circuit for a data processing system provide a partitioned interrupt controller with an efficient deferral mechanism for processing partitioned interrupt requests by executing a control instruction to encode and store a delay command (e.g., DEFER or SUSPEND) in a data payload with a hardware-inserted partition attribute (LPID) for storage to a command register () at a physical address (PA) retrieved from a special purpose register () so that the partitioned interrupt controller () can determine if the delay command can be performed based on local access control information.
