UINT32 EFIAPI TcgPpVendorLibExecutePendingRequest | ( | IN UINT32 | OperationRequest, | |
IN OUT UINT32 * | ManagementFlags, | |||
OUT BOOLEAN * | ResetRequired | |||
) |
Check and execute the requested physical presence command.
This API should be invoked in BIOS boot phase to process pending request.

If OperationRequest < 128, then ASSERT().
[in] | OperationRequest | TPM physical presence operation request. |
[in,out] | ManagementFlags | BIOS TPM Management Flags. |
[out] | ResetRequired | If reset is required to vendor settings in effect. True, it indicates the reset is required. False, it indicates the reset is not required. |
