/usr/bin/swtpm_bios [options]

Runs TPM_Startup (unless -n), then (unless -o) sets PP, enable, activate
and finally (using -u) gives up physical presence (PP)

The following options are supported:
	--tpm-device <device>  use the given device; default is /dev/tpm0
	--tcp [<host>]:[<prt>] connect to TPM on given host and port;
	                       default host is 127.0.0.1, default port is 6545
	--unix <path>          connect to TPM using UnixIO socket
	--tpm2                 initialize a TPM2
	-c                     startup clear (default)
	-s                     startup state
	-d                     startup deactivate (no effect on TPM2)
	-n                     no startup
	-o                     startup only
	-cs                    run TPM_ContinueSelfTest on TPM1.2
	                       run TPM2_IncrementalSelfTest on TPM2
	-ea                    make sure that the TPM 1.2 is activated;
	                       terminate with exit code 129 if the TPM
	                       needs to be reset
	-u                     give up physical presence
	                       on TPM 2 set the platform hierarchy to a
	                       random password
	-v                     display version and exit
	-h                     display this help screen and exit
