<p>A method for providing access to hardware devices by a processor without causing conflicts with other processors included in a computer system. The method includes receiving a first address map from a first processor and a second address map from a second processor, where each address map includes memory-mapped input/output (I/O) apertures for a set of hardware devices that the processor is configured to access. The method further includes generating a global address map by combining the first address map and the second address map, receiving a first access request from the first processor and routing the first access request to a hardware device based on an address mapping included in the global address map. Advantageously, heterogeneous processors included in multi-processor system can access any hardware device included in the computer system, without modifying the processors, one or more operating systems executed by each processor, or the hardware devices.</p> |
