-/** @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.
-
- 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().

- Enables a driver to access registers in the PI CPU I/O space.
-
- The Io.Read() and Io.Write() functions enable a driver to access PCI controller
- registers in the PI CPU I/O space.
-
- The I/O operations are carried out exactly as requested. The caller is responsible
- for satisfying any alignment and I/O width restrictions that a PI System on a
- platform might require. For example on some platforms, width requests of
- EfiCpuIoWidthUint64 do not work. Misaligned buffers, on the other hand, will
- be handled by the driver.
-
- If Width is EfiCpuIoWidthUint8, EfiCpuIoWidthUint16, EfiCpuIoWidthUint32,
- or EfiCpuIoWidthUint64, then both Address and Buffer are incremented for
- each of the Count operations that is performed.
-
- If Width is EfiCpuIoWidthFifoUint8, EfiCpuIoWidthFifoUint16,
- EfiCpuIoWidthFifoUint32, or EfiCpuIoWidthFifoUint64, then only Buffer is
- incremented for each of the Count operations that is performed. The read or
- write operation is performed Count times on the same Address.
-
- If Width is EfiCpuIoWidthFillUint8, EfiCpuIoWidthFillUint16,
- EfiCpuIoWidthFillUint32, or EfiCpuIoWidthFillUint64, then only Address is
- incremented for each of the Count operations that is performed. The read or
- write operation is performed Count times from the first element of Buffer.
-
- @param[in] This A pointer to the EFI_CPU_IO2_PROTOCOL instance.
- @param[in] Width Signifies the width of the I/O or Memory operation.
- @param[in] Address The base address of the I/O operation.
- @param[in] Count The number of I/O operations to perform. The number
- of bytes moved is Width size * Count, starting at Address.
- @param[in, out] Buffer For read operations, the destination buffer to store the results.
- For write operations, the source buffer from which to write data.
-
- @retval EFI_SUCCESS The data was read from or written to the PI system.
- @retval EFI_INVALID_PARAMETER Width is invalid for this PI system.
- @retval EFI_INVALID_PARAMETER Buffer is NULL.
- @retval EFI_UNSUPPORTED The Buffer is not aligned for the given Width.
- @retval EFI_UNSUPPORTED The address range specified by Address, Width,
- and Count is not valid for this PI system.
