The creator of the Linux OS, Linus Torvalds, vented his frustration with AMD's fTPM implementation (h/t Phoronix). Tersely characterizing the AMD fTPM as "crud," the outspoken Finnish developer appeared to suggest the best thing to do with this motherboard flash-based TPM solution would be to disable it, at least as far as using it for hardware random number generation is concerned. Torvalds noted that the CPU RDRAND instruction for the same task doesn't cause stuttering, so it could be used instead.
We have previously covered news of AMD's fTPM (firmware trusted platform module) implementation causing stuttering in Windows apps and games, and the official purported fix/workaround. Please carefully heed AMD's warning about the workaround of switching an active system from fTPM to dTPM. However, it seems like AMD's BIOS patches haven't managed to iron out all the fTPM stuttering behavior on Windows or Linux.
