Check and execute the pending TPM request and Lock TPM. | |
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. At last, it will lock TPM to prevent TPM state change by malware. | |
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. This API should also | |
be invoked as early as possible as TPM is locked in this function. | |
