"MdeModulePkg/Universal/Acpi/S3SaveStateDxe/S3SaveStateDxe.inf" produces
the EFI_S3_SAVE_STATE_PROTOCOL which allows creation and saving of an S3
Boot Script, to be replayed in PEI during S3 Resume. The script contains
opcodes and opcode arguments to configure CPU, PCI and IO resources.
S3SaveStateDxe relies on the S3BootScriptLib library. The Null
implementation is not useful for actually saving the boot script, we need
the PiDxeS3BootScriptLib instance.
The PiDxeS3BootScriptLib library instance depends on LockBoxLib,
implemented for OVMF in one of the previous patches.
PiDxeS3BootScriptLib also depends on SmbusLib. For now we opt for the Null
instance of the latter. It means that SMBus commands in the boot script
will have no effect when interpreted during S3 Resume. This should be fine
for OvmfPkg and QEMU.
EFI_S3_SAVE_STATE_PROTOCOL [S3SaveStateDxe]
S3BootScriptLib [PiDxeS3BootScriptLib]
SmbusLib [BaseSmbusLibNull]
LockBoxLib [OvmfPkg/Library/LockBoxLib]
When the EFI_DXE_SMM_READY_TO_LOCK_PROTOCOL is installed by any DXE driver
(purely as a form of notification), the S3SaveStateDxe driver saves the
boot script to EfiACPIMemoryNVS, and links it into the LockBox.
