the module can cause intermittent stuttering, depending on which Ryzen processor you’re using. It appeared when the fTPM was in use, it would access its flash storage via a serial interface, and when doing so, held up activity by the rest of the system.
Could this be why I get stuttering in games after enabling TPM installing windows 11?
I always just kill my TPM chip. It’s so obvious tpm will be used in the future for application offline DRM. They will executed encrypted operations under the TPM veil and decompilers will become unusable.
How do you kill your TPM chip?
Level 1, turn off in bios
Level 2, desolder from motherboard
Level 3, remove cpu pins related to tpm
Level 4, decap cpu, laser off tpm bus or blocks
Level 5, throw computer into a volcano and go live in the woods using no technology more complex than a flint and steel.
Thank you, the best I can do is level 2 (once I learn how to solder)
Would love this. I’m still getting the ftpm stutters and there’s no way to disable it in my motherboards bios.
Wow I’m surprised you can’t disable it. I can disable it on my desktop BIOS (Gigabyte X570S Pro AX) and my work laptop BIOS (Dell G15).
I love how Torvalds always calls it like he sees it.

Whoops. Thanks. I corrected the URL in the post.
Man, I’m glad Sync for Lemmy launched today, I really missed the automatic amp removal from links.
good thing my Ryzen 1000 series motherboard doesn’t even have TPM…I need to upgrade lool
Yup. I’ve been wondering if that was the thing that’s made the v6.4 kernels so unstable on Ryzen machines.

“Maybe use it for the boot-time ‘gather entropy from different sources,’ but clearly it should not be used at runtime.”
Good idea. Ask it during boot/
insmodfor some hardware-random bits to seed Linux’s usual software-only CSPRNG, then just use that.And even that might not be a great idea. I wouldn’t be surprised if the fTPM RNG is subtly not-entirely-random, at some alphabet agency’s behest. I remember there being a controversy over
rdrandfor this reason…The fix with any possible issues with rdrand is the same here. When entropy is gathered from many sources including hardware instructions, any nefarious plant in the chip is drowned out in a sea of noise.
I’m no cryptographer, but that seems like an awfully dangerous assumption.
Well, it’s an fTPM, aka software, and AFAIK, no software can truly have a random RNG.
So it might be very good pseudo random at best.
It could be only mostly firmware, with a hardware RNG.
If not, and it uses a CSPRNG, then I don’t see much point in using it at all. Linux already has its own CSPRNG.
Oh I disabled that a while ago because their hardware random number generator always returned 0xfffff…
Honesty, hardware random number generation seems sketchy. Something you’d expect government backdoors to be in.
I agree. If it doesn’t work, disable it until it’s fixed
