From: Laszlo Ersek <[email protected]>
This driver (from
"MdeModulePkg/Universal/Acpi/BootScriptExecutorDxe/BootScriptExecutorDxe.inf")
is first loaded normally during DXE. When the
EFI_DXE_SMM_READY_TO_LOCK_PROTOCOL is installed by any DXE driver (purely
as a form of notification), the driver reloads itself to reserved memory.
During S3 Resume / PEI, the driver image is executed from there. In order
to access the boot script saved during S3 Suspend, LockBox access is
needed.
The boot script is transferred internal to PiDxeS3BootScriptLib:
Both S3SaveStateDxe and BootScriptExecutorDxe are statically linked
against PiDxeS3BootScriptLib. Whichever is loaded first (during normal
boot, in the DXE phase), allocates the root storage for the script. The
address is then passed between the PiDxeS3BootScriptLib instances living
in the two separate drivers thru the dynamic
PcdS3BootScriptTablePrivateDataPtr PCD.
Dependencies:
BootScriptExecutorDxe
gEfiLockBoxProtocolGuid [OvmfPkg/AcpiS3SaveDxe]
S3BootScriptLib [PiDxeS3BootScriptLib]
SmbusLib [BaseSmbusLibNull]
LockBoxLib [OvmfPkg/Library/LockBoxLib]
LockBoxLib [OvmfPkg/Library/LockBoxLib]
