Do we know if the AMD Framework uses a hardware dTPM or the fTPM from AMD to stop the intermittent stuttering?

Based on Linus’ rant about fTPM causing stuttering in Linux, I’m curious if we know which way the AMD boards are going?


Relevant AMD article:

Relevant passage:
" Workaround: As an immediate solution, affected customers dependent on fTPM functionality for Trusted Platform Module support may instead use a hardware TPM (“dTPM”) device for trusted computing. Platform dTPM modules utilize onboard non-volatile memory (NVRAM) that supersedes the TPM/SPIROM interaction described in this article."


TPM expansion card when?

(would that even work? typically there is a dedicated TPM header on server and desktop motherboards)

The current generation AMD mobile chips have Microsoft Pluton, which can function as a hardware TPM if I remember correctly.

I, for one, am looking forward to knowing whether there’ll be an UEFI option to disable the fTPM.

I don’t think it makes a lot of sense due to the big attack surface (man-in-the-middle attacks) [0.1].
In my opinion it makes the most sense to combine a TPM2 with hardware intrusion detection. Note that the frameworks intrusion detection is flawed, since you can reset it when removing the battery and the CMOS battery.
