Lemme type the whole thing here again so that we have it all summed up in one place - I think we all agree by now: - confidential computing guest stuff: arch/x86/coco/{sev,tdx} - generic host virtualization stuff: arch/x86/virt/ - coco host stuff: arch/x86/virt/vmx/{tdx,vmx}.c and arch/x86/virt/svm/sev*.c New stuff goes to the new paths - i.e., TDX guest, host, etc - old stuff - AMD SEV/SNP will get moved gradually so that development doesn't get disrupted. Or we can do a flag day, right before -rc1 or so, and move it all so in one go. We'll see. Thx. -- Regards/Gruss, Boris. https://people.kernel.org/tglx/notes-about-netiquette
