Intel folks added the generic code to support a TDX guest in April, 2022. This patchset adds the Hyper-V specific code so that a TDX guest can run on Hyper-V. Please review. Thanks! Patch 1, 2 and 3 modify the generic TDX code in arch/x86/coco/tdx/. I think they should go through the x86 tip.git tree. Patch 4, 5, and 6 are for Hyper-V drivers and I think they should go through the hyperv tree. Once Michael Kelley's patchset is merged (see https://lwn.net/ml/linux-kernel/1668624097-14884-1-git-send-email-mikelley%40microsoft.com/) I'll need to rebase the 3 patches. Patch 5 depends on __tdx_ms_hv_hypercall(), which is added by patch 1.
