S3 SMM Save State Protocol as defined in PI1.2 Specification VOLUME 5 Standard.
|
|
|
|
The EFI_S3_SMM_SAVE_STATE_PROTOCOL publishes the PI SMMboot script abstractions
|
|
On an S3 resume boot path the data stored via this protocol is replayed in the order it was stored.
|
|
The order of replay is the order either of the S3 Save State Protocol or S3 SMM Save State Protocol
|
|
Write() functions were called during the boot process. Insert(), Label(), and
|
|
Compare() operations are ordered relative other S3 SMM Save State Protocol write() operations
|
|
and the order relative to S3 State Save Write() operations is not defined. Due to these ordering
|
|
restrictions it is recommended that the S3 State Save Protocol be used during the DXE phase when
|
|
every possible.
|
|
The EFI_S3_SMM_SAVE_STATE_PROTOCOL can be called at runtime and
|
|
EFI_OUT_OF_RESOURCES may be returned from a runtime call. It is the responsibility of the
|
|
platform to ensure enough memory resource exists to save the system state. It is recommended that
|
|
runtime calls be minimized by the caller.
