Method and system for the efficient response to multiple different types of interrupts

DETAILED DESCRIPTION It is therefore one object of the present invention to provide an improved method and system for the efficient response to multiple different types of interrupts in a data processing system.
It is another object of the present invention to provide an improved method and system for the initiation of reversible processing associated with a particular state of a storage subsystem controller prior to receipt of a next interrupt within a data processing system.
It is yet another object of the present invention to provide an improved method and system for the determination of a particular state of a storage subsystem controller associated with an occurrence of a selected type of interrupt in a data processing system.
The foregoing objects are achieved as is now described.
A method and system in a data processing system are disclosed for the efficient response to multiple different types of interrupts.
The data processing system includes at least one host and a storage subsystem having storage subsystem devices and at least one storage subsystem controller.
The storage subsystem controller operates in multiple different states.
Interrupts of multiple different types are generated by sources of real time events and are received by the storage subsystem controller.
A selected type of interrupt for a next interrupt to be received by the storage subsystem controller is determined in response to the determination of the current state of the storage subsystem controller.
A particular state associated with the occurrence of the selected type of interrupt is then determined.
Reversible processing associated with the particular state is initiated prior to receipt of a next interrupt.
The above as well as additional objects, features, and advantages of the present invention will become apparent in the following detailed written description.
