BOOLEAN EFIAPI TrEEPhysicalPresenceLibNeedUserConfirm | ( | VOID | ) |
Check if the pending TPM request needs user input to confirm.
The TPM request may come from OS. This API will check if TPM request exists and need user input to confirmation.
TRUE | TPM needs input to confirm user physical presence. | |

VOID EFIAPI TrEEPhysicalPresenceLibProcessRequest | ( | IN TPM2B_AUTH * | PlatformAuth | ) |
Check and execute the pending TPM request.
The TPM request may come from OS or BIOS. This API will display request information and wait for user confirmation if TPM request exists. The TPM request will be sent to TPM device after the TPM request is confirmed, and one or more reset may be required to make TPM request to take effect.
This API should be invoked after console in and console out are all ready as they are required to display request information and get user input to confirm the request.
PlatformAuth | platform auth value. NULL means no platform auth change. |
