Hi, this is the essentially final version of the TDX MMU prep series, focusing on supporting TDX's separation of EPT into a direct part (for shared pages) and a part that is managed by the TDX module and cached (into a "mirror" EPT) by KVM. The only difference from v5 is squashing in Yan's https://lore.kernel.org/kvm/20241104084229.29882-1-yan.y.zhao@xxxxxxxxx/, and a few comment and commit message updates. Paolo Isaku Yamahata (12): KVM: Add member to struct kvm_gfn_range to indicate private/shared KVM: x86/mmu: Add an external pointer to struct kvm_mmu_page KVM: x86/mmu: Add an is_mirror member for union kvm_mmu_page_role KVM: x86/tdp_mmu: Take struct kvm in iter loops KVM: x86/mmu: Support GFN direct bits KVM: x86/tdp_mmu: Extract root invalid check from tdx_mmu_next_root() KVM: x86/tdp_mmu: Introduce KVM MMU root types to specify page table type KVM: x86/tdp_mmu: Take root in tdp_mmu_for_each_pte() KVM: x86/tdp_mmu: Support mirror root for TDP MMU KVM: x86/tdp_mmu: Propagate building mirror page tables KVM: x86/tdp_mmu: Propagate tearing down mirror page tables KVM: x86/tdp_mmu: Take root types for kvm_tdp_mmu_invalidate_all_roots() Paolo Bonzini (1): KVM: x86/tdp_mmu: Propagate attr_filter to MMU notifier callbacks Rick Edgecombe (5): KVM: x86/mmu: Zap invalid roots with mmu_lock held for write at uninit KVM: x86: Add a VM type define for TDX KVM: x86/mmu: Make kvm_tdp_mmu_alloc_root() return void KVM: x86/tdp_mmu: Don't zap valid mirror roots in kvm_tdp_mmu_zap_all() KVM: x86/mmu: Prevent aliased memslot GFNs arch/x86/include/asm/kvm-x86-ops.h | 4 + arch/x86/include/asm/kvm_host.h | 26 ++- arch/x86/include/uapi/asm/kvm.h | 1 + arch/x86/kvm/mmu.h | 31 +++ arch/x86/kvm/mmu/mmu.c | 50 ++++- arch/x86/kvm/mmu/mmu_internal.h | 64 +++++- arch/x86/kvm/mmu/spte.h | 5 + arch/x86/kvm/mmu/tdp_iter.c | 10 +- arch/x86/kvm/mmu/tdp_iter.h | 21 +- arch/x86/kvm/mmu/tdp_mmu.c | 325 ++++++++++++++++++++++------- arch/x86/kvm/mmu/tdp_mmu.h | 51 ++++- arch/x86/kvm/x86.c | 3 + include/linux/kvm_host.h | 6 + virt/kvm/guest_memfd.c | 2 + virt/kvm/kvm_main.c | 14 ++ 15 files changed, 506 insertions(+), 107 deletions(-) -- 2.43.5
