TPM Management - tpm_setownable
NAME
tpm_setownable - change whether the TPM allows tpm_takeownership operations
SYNOPSIS
tpm_setownable [OPTION]
DESCRIPTION
tpm_setownable
reports the status of the TPM’s flags regarding if the
TPM can be owned. This is the default behavior and also
accessible via the --status option. Requesting a
report of this status prompts for the owner password. The
--allow option sets the system’s TPM to allow
tpm_takeownership operations (via the TPM_SetOwnerInstall
API). This operation requires physical presence. The
--prevent option (via the TPM_SetOwnerInstall API)
prevents the TPM from accepting tpm_takeownership
operations. This operation requires physical presence. These
operations are persistent. tpm_takeownership requires the
tpm be enabled.
