The two patches (which are based on the latest x86/tdx branch in the tip tree) are the x86/tdx part of the v6 patchset: https://lwn.net/ml/linux-kernel/20230504225351.10765-1-decui@xxxxxxxxxxxxx/ 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 v7 patchset addressed Dave's comments on patch 1: see https://lwn.net/ml/linux-kernel/SA1PR21MB1335736123C2BCBBFD7460C3BF46A@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/ 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 x86/tdx branch of 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) If you want to view the patchset on github, it is here: https://github.com/dcui/tdx/commits/decui/upstream-tip/x86/tdx/v7 Thanks, Dexuan Dexuan Cui (2): x86/tdx: Retry TDVMCALL_MAP_GPA() when needed x86/tdx: Support vmalloc() for tdx_enc_status_changed() arch/x86/coco/tdx/tdx.c | 123 +++++++++++++++++++++++++++++++--------- 1 file changed, 96 insertions(+), 27 deletions(-) -- 2.25.1
