I'm having trouble finding TPM troubleshooting tips. Any pointers?

I've installed 4.x RC4 on a Lenovo thinkpad P51. The HCL (attached) shows

TPM: Device not found

In the bios, TPM 2.0 is enabled.

Thanks in advance. -Dave

Dave, did you ever get TPM working on your P51?

I have the same exact model of P51 (20HHCTO1WW) and I love it. It's loaded up with 32GB RAM and 1TB NVMe SSD.  But I was hoping to use it with Qubes and TPM.

Sounds like Qubes didn't (and still doesn't?) support TPM 2.0:

I'm a firmware developer myself, though so far not on PCs yet.  I'm wondering if integrating support for TPM 2.0 is beyond my ability or more a matter of the very capable core maintainers being occupied with higher-priority stuff.  If it's the latter, perhaps I could try it...

Actually, it looks like the excellent Trammell Hudson is on the case:
