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 Dexuan Cui (5): x86/tdx: Retry TDVMCALL_MAP_GPA() when needed x86/tdx: Support vmalloc() for tdx_enc_status_changed() x86/hyperv: Add hv_isolation_type_tdx() to detect TDX guests x86/hyperv: Support hypercalls for TDX guests Drivers: hv: vmbus: Support TDX guests Kirill A.
