From: Isaku Yamahata <isaku.yamahata@xxxxxxxxx> Hello. I've updated the patch series based on the feedback. Here are the discussion points. - 06/11 KVM: x86: Introduce PFERR_GUEST_ENC_MASK to indicate fault is private Michael has his own opinion on how to indicate private fault. - 09/11 KVM: Add new members to struct kvm_gfn_range to operate on - 10/11 KVM: x86: Add gmem hook for initializing private memory SNP needs the callback. TDX won't use this one. - 11/11 KVM: x86: Add gmem hook for invalidating private memory SNP needs the callback. TDX doesn't use this one at the moment, but would use it. - VM type: I didn't rename KVM_X86_PROTECTED_VM to KVM_X86_SW_PROTECTED_VM in this patch series. It's easy to rename it if desired. Thanks, This is an RFC patch series based on KVM gmem [1] and [2] for the common use of TDX and SEV-SNP. [1] KVM gmem patches https://github.com/sean-jc/linux/tree/x86/kvm_gmem_solo [2] Add AMD Secure Nested Paging (SEV-SNP) Hypervisor Support https://lore.kernel.org/lkml/20230612042559.375660-1-michael.roth@xxxxxxx/ --- v3: - Imported common patches from Michael Roth which can be useful for both SNP and TDX. And reorder patches. - Update struct kvm_gfn_range to drop flag, and add add only_private, and only_shared - Update kvm_arch_set_memory_attributes() and added a x86 vendor callback for it. v2: https://lore.kernel.org/all/cover.1687474039.git.isaku.yamahata@xxxxxxxxx/ v1: https://lore.kernel.org/all/cover.1686858861.git.isaku.yamahata@xxxxxxxxx/ Brijesh Singh (1): KVM: x86: Export the kvm_zap_gfn_range() for the SNP use Isaku Yamahata (8): KVM: selftests: Fix test_add_overlapping_private_memory_regions() KVM: selftests: Fix guest_memfd() KVM: selftests: x86: typo in private_mem_conversions_test.c KVM: x86: Add is_vm_type_supported callback KVM: x86/mmu: Pass around full 64-bit error code for the KVM page fault KVM: x86: Introduce PFERR_GUEST_ENC_MASK to indicate fault is private KVM: Fix set_mem_attr ioctl when error case KVM: Add new members to struct kvm_gfn_range to operate on Michael Roth (2): KVM: x86: Add gmem hook for initializing private memory KVM: x86: Add gmem hook for invalidating private memory arch/x86/include/asm/kvm-x86-ops.h | 4 ++ arch/x86/include/asm/kvm_host.h | 12 +++++ arch/x86/include/uapi/asm/kvm.h | 1 + arch/x86/kvm/mmu.h | 2 - arch/x86/kvm/mmu/mmu.c | 51 ++++++++++++++----- arch/x86/kvm/mmu/mmu_internal.h | 20 ++++++-- arch/x86/kvm/mmu/mmutrace.h | 2 +- arch/x86/kvm/mmu/paging_tmpl.h | 2 +- arch/x86/kvm/svm/svm.c | 7 +++ arch/x86/kvm/vmx/vmx.c | 6 +++ arch/x86/kvm/x86.c | 16 +++++- arch/x86/kvm/x86.h | 2 + include/linux/kvm_host.h | 16 ++++-- .../testing/selftests/kvm/guest_memfd_test.c | 4 +- .../selftests/kvm/set_memory_region_test.c | 16 +++++- .../kvm/x86_64/private_mem_conversions_test.c | 2 +- virt/kvm/guest_mem.c | 50 +++++++++++++++++- virt/kvm/kvm_main.c | 24 +++++---- 18 files changed, 192 insertions(+), 45 deletions(-) base-commit: be8abcec83c87d4e15ae04816b685fe260c4bcfd -- 2.25.1
