Abstract
A method and circuit for a data processing system provide virtualized instructions for accessing a partitioned device (e.g.,) by executing a control instruction () to encode and store an access command (CMD) 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 device () can determine if the access command can be performed based on local access control information.
