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