Subject: [PATCH 0/6] Support TDX guests on Hyper-V
Date: Mon, 21 Nov 2022 11:51:45 -0800	[thread overview]
Message-ID: <20221121195151.21812-1-decui@microsoft.com> (raw)

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.

Thanks,
Dexuan
