A hook-in library for:
|
|
- MdeModulePkg/Universal/Variable/Pei/VariablePei.inf
|
|
- MdeModulePkg/Universal/Variable/RuntimeDxe/VariableRuntimeDxe.inf
|
|
- MdeModulePkg/Universal/Variable/RuntimeDxe/VariableSmm.inf
|
|
|
|
Plugging this library instance into one of the above modules makes that
|
|
variable service backend wait for another platform module to dynamically
|
|
initialize or verify EFI_FIRMWARE_VOLUME_HEADER and VARIABLE_STORE_HEADER in
|
|
the non-volatile variable store FVB device. The initialization / verification
|
|
is signaled by installing gEdkiiNvVarStoreFormattedGuid into the
|
|
phase-matching PPI or protocol database, with a NULL interface. (Note that
|
|
installing gEdkiiNvVarStoreFormattedGuid into either the DXE or the MM
|
|
protocol database will unblock VariableSmm -- refer to EFI_SECTION_MM_DEPEX
|
|
in the PI spec.)
