Issue with TDX version when using QEMU

[ginsama01]

Describe the support request
Hello, I am following your instruction to run and experiment TDX using QEMU. I have an issue about the TDX version. When I check the kernel log from host OS side, I get TDX version 1.5:

But when I check the kernel log inside the TD, I get this kernel log, mention that BIOS 2024.02-3+tdx 1.0. I am not sure what it means, and what exactly TDX version I get.

I want to do some experiments on TDX 1.5, what should I do now?
Thank you!

As your host OS shows version 1.5 for the Intel TDX Module, this is the Intel TDX Module hat will be used to actually load the TD.

Could you elaborate on what exactly you want to test and what currently prevents you from testing it? This might help in providing additional insights.

Thanks for your answer. I want to test some vulnerabilities reported in TDX 1.0, see if they work in TDX 1.5. But I'm confused as to whether I'm testing with TDX 1.5 or 1.0 because when I check the kernel log inside the TD guest, it shows "tdx 1.0". I don't understand what this means.
