tpm2-tss VS swtpm

If everything fails again, you may just need to build from source. I think I found what you are looking for but don't take it as set in stone - https://github.com/tpm2-software/tpm2-tss.

I’m just throwing this out here for those more knowledgeable than me. I was thinking that running a software TPM could be a way in which to trick Windows in to believing you have chip and would be great for those people who otherwise might nit be able to run 11 as far as we know right now. However I don’t have any idea if this would actually work or if anybody has used it in the past. https://github.com/tpm2-software/tpm2-tss

Or you can just add a virtual tpm device in virt-manager while setting up the vm using swtpm. It seems to ha e packages on most major distro's.

If you want Windows 11 instead for whatever reason, swtpm can emulate a TPM chip for QEMU to use.

You can find the source of software TPM implementations which abide to the official spec such as: https://github.com/stefanberger/swtpm but that has no real bearings on the TPM used on real hardware

I install swtpm and in virt-manager add a TPM 2.0 emulated device and set the secure boot image before I install. This seems to work well enough.

I don't know either, but apparently Microsoft didn't guarantee that 'unsupported' systems would continue to receive system updates. I just use a QEMU VM and swtpm.

swtpm - a software Trusted Platform Module emulator and the ways of using it;

Seems there are two such projects for that:

Linux has several TPM emulators. This one is probably the most popular. But here's another for TPM 1.2 only. The main use-case is to emulate TPMs for use with Virtual Machine guests.

Other GitHub posts from previous versions seem to have the issue described here but maybe I missed something, https://github.com/stefanberger/swtpm/issues/572 I'm on an arch install and just installed it from pacman.
