[PATCH v2 0/6] Support TDX guests on Hyper-V
From: Dexuan Cui
Date: Tue Dec 06 2022 - 19:34:51 EST
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@xxxxxxxxxxxxx/
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
