14
16 tpm_setownable reports the status of the TPM's flags regarding if the
17 TPM can be owned. This is the default behavior and also accessible via
18 the --status option. Requesting a report of this status prompts for the
19 owner password. The --allow option sets the system's TPM to allow
20 tpm_takeownership operations (via the TPM_SetOwnerInstall API). This
21 operation requires physical presence. The --prevent option (via the
22 TPM_SetOwnerInstall API) prevents the TPM from accepting
23 tpm_takeownership operations. This operation requires physical
24 presence. These operations are persistent. tpm_takeownership requires
25 the tpm be enabled.
