The EFI_SMM_SWAP_ADDRESS_RANGE_PROTOCOL is related to EDK II-specific implementation
|
|
and used to abstract the swap operation of boot block and backup block of FV in EFI
|
|
SMM environment. This swap is especially needed when updating the boot block of FV.
|
|
If a power failure happens during the boot block update, the swapped backup block
|
|
(now the boot block) can boot the machine with the old boot block backed up in it.
|
|
The swap operation is platform dependent, so other protocols such as SMM FTW (Fault
|
|
Tolerant Write) should use this protocol instead of handling hardware directly.
