How do I get some minimal information about the TPM chip in my Linux laptop?

Information such as the manufacturer, manufacturer id, manufacturer version.

So far I have tried the tpm2_getcap command to get some vendor information.

tpm2_getcap vendor and tpm2_getcap vendor:2. both times I get the following error,

WARNING:esys:src/tss2-esys/api/Esys_GetCapability.c:301:Esys_GetCapability_Finish() Received TPM Error 
ERROR:esys:src/tss2-esys/api/Esys_GetCapability.c:106:Esys_GetCapability() Esys Finish ErrorCode (0x000001c4) 
ERROR: Esys_GetCapability(0x1C4) - tpm:parameter(1):value is out of range or is not correct for the context
ERROR: Unable to run tpm2_getcap

Side Note: Commands such as tpm2_getcap algorithms and tpm2_getcap pcrs works fine.

Are you 100% you have a discrete TPM?

Yes.

  • Perhaps you have a tpm1 rather than a tpm2 chip. You need to hunt out the specs for the laptop. If you do have a tpm1 running chip,. then you /may/ be able to update its firmware for tpm2. That code can be found somewhere on the supermicro web site.
