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.
