Abstract
A method implemented in a data processing system comprising receiving an input/output (IO) write request from a processing thread to transfer data from a memory of the data processing system to an IO device, setting the memory as read-only memory to protect the data from overwrite before the data is transferred to the IO device, and sending, in response to the IO write request, a speculative IO write completion response to the processing thread to enable the processing thread to continue execution without waiting for the data to be transferred to the IO device.
