tpm_setactive(8)
NAME
tpm_setactive - change TPM active states
SYNOPSIS
tpm_setactive [OPTION]
DESCRIPTION
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.
