Abstract:
A mechanism is provided for offloading an input/output (I/O) completion operation. Responsive to a second processor identifying that a flag has been set by a first processor requesting assistance in completing an I/O operation, the second processor copies an I/O response from a first I/O response data structure associated with the first processor to a second I/O response data structure associated with the second processor. The second processor deletes the I/O response from the first I/O response data structure, clears the flag, and processes the I/O operation by addressing the I/O response in the second I/O response data structure. Responsive to completing the I/O operation, the second processor deletes the I/O response from the second I/O response data structure.
