TPM Management - tpm_setenable
NAME¶
tpm_setenable - change TPM enable states
SYNOPSIS¶
tpm_setenable [
OPTION]
DESCRIPTION¶
tpm_setenable reports the status of the TPM's flags regarding the enable
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
--enable option changes the system's TPM to the
enabled state (via the TPM_OwnerSetDisable API). This operation prompts for
the owner password and is persistent. The
--disable option (via the
TPM_OwnerSetDisable API) changes the system's TPM to the disabled state. This
operation prompts for the owner password and is persistent. A disabled TPM is
essentially off and does not allow a tpm_takeownership to occur. The
--force option overrides the owner password prompt and relies on
physical presence for the operation authorization (via the TPM_PhysicalEnable
and TPM_PhysicalDisable APIs). The
--enable,
--disable, and
--status options are mutually exclusive and the last one on the command
line will be carried out.
