/** @file
This files describes the CPU I/O 2 Protocol.
This protocol provides an I/O abstraction for a system processor. This protocol
is used by a PCI root bridge I/O driver to perform memory-mapped I/O and I/O transactions.
The I/O or memory primitives can be used by the consumer of the protocol to materialize
bus-specific configuration cycles, such as the transitional configuration address and data
ports for PCI. Only drivers that require direct access to the entire system should use this
protocol.
ports for PCI. Only drivers that require direct access to the entire system should use this
protocol.
Note: This is a boot-services only protocol and it may not be used by runtime drivers after
ExitBootServices(). It is different from the Framework CPU I/O Protocol, which is a runtime
protocol and can be used by runtime drivers after ExitBootServices().
