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.

Abstract translation: 一种在数据处理系统中实现的方法，包括从处理线程接收输入/输出（IO）写入请求，以将数据从数据处理系统的存储器传送到IO设备，将存储器设置为只读存储器，以保护 在将数据传送到IO设备之前，覆盖的数据被重写，并且响应于IO写入请求，发送对处理线程的推测性IO写入完成响应，以使得处理线程能够继续执行而不等待数据被传送 到IO设备。
