TPM Management - tpm_setactive
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 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.
