Apparatus for dynamic resource mapping for isolating interrupt sources and method therefor

A data processing system comprising:

• a central processing unit (CPU);
• and
• a plurality of peripheral devices coupled to said CPU, wherein said CPU includes circuitry operable for dynamic resource mapping for isolating interrupts from said plurality of peripheral devices, said circuitry comprising:
• circuitry operable for providing a plurality of interrupt source device identifiers, wherein each identifier corresponds to one of said plurality of peripheral devices;
• circuitry operable for generating a first table mapping said interrupt source identifiers to corresponding interrupt numbers;
• and
• circuitry operable for associating an interrupt, represented by one of said interrupt numbers, with a corresponding device generating said interrupt using said first table.

A program product in a computer readable medium for dynamic resource mapping for isolating interrupt sources, said program product comprising:

• programming for providing a plurality of interrupt source device identifiers, wherein each identifier corresponds to one of a plurality of interrupt sources;
• programming for generating a first table mapping said interrupt source identifiers to corresponding interrupt numbers;
• and
• programming for associating an interrupt, represented by one of said interrupt numbers, with a corresponding device generating said interrupt using said first table.
