Apparatus and method for sharing devices between multiple execution domains of a hardware platform

A system, comprising:

• a multi-core processor;
• a memory;
• a chipset coupled between the processor and the memory, the chipset comprising:
• an input/output (I/O) hub (IOH), including a controller having a domain manager logic to intercept at least one configuration request from an execution domain of at least two execution domains partitioned within the multi-core processor, the configuration request including configuration information assigned by the execution domain to enable access to one of an end-point device, an interconnect, and a bridge that is a target of the configuration request, the logic domain manager including:
• translation logic to store the configuration information decoded from the intercepted configuration request as virtual configuration information in conjunction with corresponding actual configuration information assigned to the target to enable translation of access requests issued by the at least two execution domains;
• and
• a wireless transmitter and receiver circuitry coupled to the chipset.

An article of manufacture having a machine accessible medium including associated data, wherein the data, when accessed by a machine, results in the machine performing operations comprising:

• detecting a configuration write request from a source domain of at least two execution domains of a partitioned hardware platform, the configuration write request having a target address within a virtual configuration address range;
• identifying a target of the configuration write request as one of a bridge and a non-bridge device;
• updating an address translation table if an interconnect device function number of the configuration write request indicates a non-bridge device and a target of the configuration write request is a configuration register of the non-bridge device;
• and
• updating a bus number translation table if the interconnect device function number of the configuration write request indicates a bridge and an interconnect number register of the bridge is the target of the configuration write request.
