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
|
|
|
|
@param This Pointer to the DXE IPL PPI instance
|
|
@param PeiServices Pointer to the PEI Services Table.
|
|
@param HobList Pointer to the list of Hand-Off Block (HOB) entries.
|
|
|
|
@retval EFI_SUCCESS Upon this return code, the PEI Foundation should enter
|
|
some exception handling.Under normal circumstances,
|
|
the DXE IPL PPI should not return.
