This code abstracts the CPU IO Protocol which installed by some platform or chipset-specific
|
|
PEIM that abstracts the processor-visible I/O operations.
|
|
|
|
Note: This is a runtime protocol and can be used by runtime drivers after ExitBootServices().
|
|
It is different from the PI 1.2 CPU I/O 2 Protocol, which is a boot services only protocol
|
|
and may not be used by runtime drivers after ExitBootServices().
