EFI_DXE_IPL_ENTRY

typedef EFI_STATUS(EFIAPI * EFI_DXE_IPL_ENTRY) (IN CONST EFI_DXE_IPL_PPI *This, IN EFI_PEI_SERVICES **PeiServices, IN EFI_PEI_HOB_POINTERS HobList)

The architectural PPI that the PEI Foundation invokes when there are no additional PEIMs to invoke.

This function is invoked by the PEI Foundation. The PEI Foundation will invoke this service when there are no additional PEIMs to invoke in the system. If this PPI does not exist, it is an error condition and an ill-formed firmware set. The DXE IPL PPI should never return after having been invoked by the PEI Foundation. The DXE IPL PPI can do many things internally, including the following:

• Invoke the DXE entry point from a firmware volume
• Invoke the recovery processing modules
• Invoke the S3 resume modules

Parameters

This	Pointer to the DXE IPL PPI instance
PeiServices	Pointer to the PEI Services Table.
HobList	Pointer to the list of Hand-Off Block (HOB) entries.

Return values

EFI_SUCCESS

Upon this return code, the PEI Foundation should enter some exception handling.Under normal circumstances, the DXE IPL PPI should not return.
