Date: Mon, 2 Mar 2020 18:02:33 -0800 From: Sean Christopherson <sean.j.christopherson@...el.com> To: Paolo Bonzini <pbonzini@...hat.com> Cc: Sean Christopherson <sean.j.christopherson@...el.com>, Vitaly Kuznetsov <vkuznets@...hat.com>, Wanpeng Li <wanpengli@...cent.com>, Jim Mattson <jmattson@...gle.com>, Joerg Roedel <joro@...tes.org>, kvm@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH v3 0/7] KVM: x86/mmu: nVMX: 5-level paging cleanup and enabling Clean up MMU code related to 5 level paging, expose 5-level EPT to L1, and additional clean up on top (mostly renames of functions/variables that caused me no end of confusion when trying to figure out what was broken at various times). v3: - Dropped fixes for existing 5-level bugs (merged for 5.6). - Use get_guest_pgd() instead of get_guest_cr3_or_eptp(). [Paolo] - Add patches to fix MMU role calculation to play nice with 5-level paging without requiring additional CR4.LA_57 bit. v2: - Increase the nested EPT array sizes to accomodate 5-level paging in the patch that adds support for 5-level nested EPT, not in the bug fix for 5-level shadow paging. Sean Christopherson (7): KVM: x86/mmu: Don't drop level/direct from MMU role calculation KVM: x86/mmu: Drop kvm_mmu_extended_role.cr4_la57 hack KVM: nVMX: Allow L1 to use 5-level page walks for nested EPT KVM: nVMX: Rename nested_ept_get_cr3() to nested_ept_get_eptp() KVM: nVMX: Rename EPTP validity helper and associated variables KVM: x86/mmu: Rename kvm_mmu->get_cr3() to ->get_guest_pgd() KVM: nVMX: Drop unnecessary check on ept caps for execute-only arch/x86/include/asm/kvm_host.h | 3 +- arch/x86/include/asm/vmx.h | 12 +++++++ arch/x86/kvm/mmu/mmu.c | 59 +++++++++++++++++---------------- arch/x86/kvm/mmu/paging_tmpl.h | 4 +-- arch/x86/kvm/svm.c | 2 +- arch/x86/kvm/vmx/nested.c | 52 ++++++++++++++++++----------- arch/x86/kvm/vmx/nested.h | 4 +-- arch/x86/kvm/vmx/vmx.c | 3 +- arch/x86/kvm/x86.c | 2 +- 9 files changed, 82 insertions(+), 59 deletions(-) -- 2.24.1
