EFI SMM Access2 Protocol as defined in the PI 1.2 specification.
|
|
|
|
This protocol is used to control the visibility of the SMRAM on the platform.
|
|
It abstracts the location and characteristics of SMRAM. The expectation is
|
|
that the north bridge or memory controller would publish this protocol.
|
|
|
|
The principal functionality found in the memory controller includes the following:
|
|
- Exposing the SMRAM to all non-SMM agents, or the "open" state
|
|
- Shrouding the SMRAM to all but the SMM agents, or the "closed" state
|
|
- Preserving the system integrity, or "locking" the SMRAM, such that the settings cannot be
|
|
perturbed by either boot service or runtime agents
