EFI MM Base Protocol as defined in the PI 1.5 specification.
|
||
|
|
|
||
|
|
This protocol is utilized by all MM drivers to locate the MM infrastructure services and determine
|
||
|
|
whether the driver is being invoked inside MMRAM or outside of MMRAM.

This service is used to indicate whether the driver is currently executing in the MM Initialization
|

phase. For MM drivers, this will return TRUE in InMmram while inside the driver's entry point and
|

|

otherwise FALSE. For combination MM/DXE drivers, this will return FALSE in the DXE launch. For the

MM launch, it behaves as an MM driver.
