Sharing virtual functions in a shared virtual memory between heterogeneous processors of a computing platform

A method to be performed in a computing platform having a plurality of heterogeneous processors including at least a first processor and a second processor, the method comprising:

• creating a shared object including a plurality of virtual functions that can be utilized by the first processor and the second processor,
• storing the shared object in a shared virtual memory accessible by the first processor and the second processor,
• identifying a first processor side virtual table for the virtual functions of the shared object to be called by the first processor,
• identifying a second processor side virtual table for the virtual functions of the shared object to be called by the second processor,
• creating a shared non-coherent region within the shared virtual memory to store the first processor side virtual table and the second processor side virtual table,
• modifying a virtual pointer pointing to the first processor side virtual table and the second processor side virtual table to point to the shared non-coherent region,
• copying virtual tables of the shared object from private address spaces of the first processor and the second processor into the shared non-coherent re ion wherein the virtual tables of the shared object are located at a same address in the shared non-coherent region even if contents of the virtual tables are different, and
• selecting an appropriate virtual function from the shared non-coherent region, wherein use of the shared non-coherent region by the first processor and the second processor enables the first processor and the second processor to share at least one of the plurality of virtual functions.

A non-transitory machine-readable storage medium comprising a plurality of instructions that in response to being executed result in a computing platform:

• creating a shared object including a plurality of virtual functions that can be utilized by the first processor and the second processor and a function pointer to a registration function,
• identifying a first processor side virtual table pointer for the shared object,
• determining a second processor side virtual table using the first processor side virtual table pointer,
• registering a class name and a first processor side virtual table address in a first table while performing a registration function on the first processor,
• registering the class name and a second processor side virtual table address in a second table while performing the registration function on the second processor,
