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