/**

This function provides a platform-specific method to detect whether the platform
|
||
|
|
is operating by a physically present user.
|
||
|
|
|
||
|
|
Programmatic changing of platform security policy (such as disable Secure Boot,
|
||
|
|
or switch between Standard/Custom Secure Boot mode) MUST NOT be possible during
|
||
|
|
Boot Services or after exiting EFI Boot Services. Only a physically present user
|
||
|
|
is allowed to perform these operations.
|
||
|
|
|
||
|
|
NOTE THAT: This function cannot depend on any EFI Variable Service since they are
|
||
|
|
not available when this function is called in AuthenticateVariable driver.
|
||
|
|
|
||
|
|
@retval TRUE The platform is operated by a physically present user.
|
||
|
|
@retval FALSE The platform is NOT operated by a physically present user.
