[PATCH v2 0/6] Support TDX guests on Hyper-V

Posted by Dexuan Cui 2 years, 9 months ago

This patchset adds the Hyper-V specific code so that a TDX guest can run
on Hyper-V. Please review. Thanks!

v1 is here:
https://lwn.net/ml/linux-kernel/20221121195151.21812-1-decui@microsoft.com/

I think I addressed all the comments received against v1. Please let me
know in case I missed anything.

I added a section "changes in v2" in each patch: in patch 0002, the
section contains a few questions. Please refer to the patch.

This v2 pathset is based on the hyperv-next branch:
https://git.kernel.org/pub/scm/linux/kernel/git/hyperv/linux.git/log/?h=hyperv-next

Thanks,
Dexuan

Hi Kiril, Sathyanarayanan, thanks for your comments. It'd be great if you
can comment on other patches.

Hi Dave, can you please also share your thoughts, especially for
patch 1, 2, 4 and 5?

Thanks,
