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.
