The entry point of PE/COFF Image for a Standalone MM Driver.
|
|
|
|
This function is the entry point for a Standalone MM Driver.
|
|
This function must call ProcessLibraryConstructorList() and
|
|
ProcessModuleEntryPointList().
|
|
If the return status from ProcessModuleEntryPointList()
|
|
is an error status, then ProcessLibraryDestructorList() must be called.
|
|
The return value from ProcessModuleEntryPointList() is returned.
|
|
If _gDriverUnloadImageCount is greater than zero, then an unload
|
|
handler must be registered for this image
|
|
and the unload handler must invoke ProcessModuleUnloadList().
|
|
If _gUefiDriverRevision is not zero and SystemTable->Hdr.Revision is less
|
|
than _gUefiDriverRevison, then return EFI_INCOMPATIBLE_VERSION.
|
|
|
|
|
|
@param ImageHandle The image handle of the Standalone MM Driver.
|
|
@param SystemTable A pointer to the EFI System Table.
|
|
|
|
@retval EFI_SUCCESS The Standalone MM Driver exited normally.
|
|
@retval EFI_INCOMPATIBLE_VERSION _gUefiDriverRevision is greater than
|
|
SystemTable->Hdr.Revision.
