I'm still unclear on what is missing/needs investigation for TPM support?

macpijan commented 2 years ago

@tlaurion We have just tried one TPM we had on hand (2.0 with LPC interface) and failed.

What needs investigation:

find out which TPMs are in use by the Talos II owners,
try out a different TPM model (preferably over SPI? I2C is almost impossible to get)
try it out on a full-blown OS (e.g. Ubuntu).

Maybe let's ask question at Raptor Forum? What are the chances to leverage lpnTPM?
