LockBoxLib has two sets of implementations. The Null implementation (which
is the OVMF default) is not useful for us any longer; we need the library
instances that back the LockBox structure with SMRAM -- the SmmLockBoxLib
variants.
These variants (library instances) are for:
- DXE_DRIVER, DXE_RUNTIME_DRIVER, UEFI_DRIVER, UEFI_APPLICATION: usable
from "untrusted", 3rd party drivers; communicates with the SmmLockBox
driver (which is trusted and runs in SMM).
- PEIM: same purpose but for PEIMs.
- DXE_SMM_DRIVER: this is the low level driver that runs inside the
trusted SmmLockBox driver, and manipulates SMRAM.
LockBoxLib [SmmLockBoxDxeLib]
EFI_SMM_COMMUNICATION_PROTOCOL [PiSmmCore]
EFI_SMM_ACCESS2_PROTOCOL [EmuSmmDxe]
EFI_SMM_CONTROL2_PROTOCOL [EmuSmmDxe]
gEfiSmmLockBoxCommunicationGuid [SmmLockBox]
EFI_SMM_ACCESS2_PROTOCOL [EmuSmmDxe]
gEfiSmmSwDispatch2ProtocolGuid [unneeded / EmuSmmDxe]
LockBoxLib [SmmLockBoxSmmLib]
In this patch, we resolve the library class only for DXE_RUNTIME_DRIVER
and DXE_SMM_DRIVER (which is sufficient to build and run OvmfPkg). We'll
add the other resolutions when we need them.
