Subject: [PATCH v8 0/2] Support TDX guests on Hyper-V (the x86/tdx part)
Date: Tue, 20 Jun 2023 08:48:28 -0700 [thread overview]
Message-ID: <20230620154830.25442-1-decui@microsoft.com> (raw)
v8 is a rebased version of v7:
v8 is based on tip.git's master branch, which has commit
75d090fd167a ("x86/tdx: Add unaccepted memory support"), so I have
to rebase v7 to the commit and post v8.
v7 is based on tip.git's x86/tdx branch.
The two patches (which are based on the latest master branch of the tip
tree) are the x86/tdx part of the v6 patchset:
https://lwn.net/ml/linux-kernel/20230504225351.10765-1-decui@microsoft.com/
The other patches of the v6 patchset needs more changes in preparation for
the upcoming paravisor support, so let me post the x86/tdx part first.
This v8 patchset addressed Dave's comments on patch 1:
see https://lwn.net/ml/linux-kernel/SA1PR21MB1335736123C2BCBBFD7460C3BF46A@SA1PR21MB1335.namprd21.prod.outlook.com/
Patch 2 is just a repost. There was a race between set_memory_encrypted()
and load_unaligned_zeropad(), which has been fixed by the 3 patches of
Kirill in the tip tree:
3f6819dd192e ("x86/mm: Allow guest.enc_status_change_prepare() to fail")
195edce08b63 ("x86/tdx: Fix race between set_memory_encrypted() and load_unaligned_zeropad()")
94142c9d1bdf ("x86/mm: Fix enc_status_change_finish_noop()")
(see https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/log/?h=x86/tdx)
