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.

You must assume the root role. For more information, see Using Your Assigned Administrative Rights in Securing Users and Processes in Oracle Solaris 11.4.

1. In 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 TPM might be disabled. For information about how to enable the device, see either How to Initialize TPM Using the Oracle ILOM Interface (SPARC Only) or How to Initialize TPM Using BIOS (x86 Only) 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 the prtconf command provides.

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