How to Check Whether the TPM Device Is Recognized by the Operating System

Use this procedure to determine whether Oracle Solaris recognizes the installed TPM device. This procedure applies to both SPARC and x86 systems.

• On a terminal window, issue the following command:

  # prtconf -v |grep tpm

  If the TPM device is recognized, the command generates output similar to the following:

  # prtconf -v |grep tpm
  tpm, instance #0
  dev_path=/pci@0,0/isa@lf/tpm@0,fed40000:tpm
  dev_link=/dev/tpm

  If no output is generated, then the device might be disabled. For information about how to enable the device, see either How to Initialize TPM Using the Oracle ILOM Interface or How to Initialize TPM Using BIOS depending on your system's platform.

  Note -  As an alternative, you can also use the ls command to obtain the same information. However, the output would contain less information than what is provided by the prtconf syntax.

  # ls -l /dev/tpm
  lrwxrwxrwx  1 root root  44 May 22 2012 /dev/tpm ->
  ../devices/pci@0,0/isa@lf/tpm@0,fed40000:tpm
