Abstract:
Methods and apparatus for opportunistic improvement of Memory Mapped Input/Output (MMIO) request handling (e.g., based on target reporting of space requirements) are described. In one embodiment, logic in a processor may detect one or more bits in a message that is to be transmitted from an input/output (I/O) device. The one or more bits may indicate memory mapped I/O (MMIO) information corresponding to one or more attributes of the I/O device. Other embodiments are also disclosed.
