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