tpm_setactive reports the status of the TPM's flags regarding the active state of the TPM. This is the default behavior and also accessible via the --status option. Requesting a report of this status prompts for the owner password. The --active option changes the TPM to the active state (via the TPM_PhysicalSetDeactivated API). This operation requires evidence of physical presence, is persistent and requires a reboot to take affect. The --inactive option (via the TPM_PhysicalSetDeactivated API) changes the TPM to the inactive state. This operation requires evidence of physical presence, is persistent and requires a reboot to take affect. An inactive TPM is essentially off but still allows for a tpm_takeownership to occur. The --temp option causes deactivation (via the TPM_SetTempDeactivated API) to happen immediately but only endure for the current boot cycle. The --status, --active, --inactive, and --temp options are mutually exclusive and the last one on the command line will be carried out.
