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.

Service to indicate whether the driver is currently executing in the MM Initialization phase.

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.

This function returns the location of the Management Mode Service Table (MMST). The use of the

some driver global variable so that the MMST can be invoked in subsequent handlers.
