RETURN_STATUS EFIAPI NvVarStoreFormattedInitialize (VOID)
 

Detailed Description

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.)
