tpm_setactive - Man Page

tpm_setactive [OPTION]

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 effect. 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 effect.  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.
