From: Lan Tianyu <Tianyu.Lan@xxxxxxxxxxxxx> This patchset is to introduce hv ept tlb range list flush function support in the KVM MMU component. Flushing ept tlbs of several address range can be done via single hypercall and new list flush function is used in the kvm_mmu_commit_zap_page() and FNAME(sync_page). This patchset also adds more hv ept tlb range flush support in more KVM MMU function. This patchset is based on the fix patch "x86/Hyper-V: Fix definition HV_MAX_FLUSH_REP_COUNT". (https://www.mail-archive.com/linux-kernel at vger.kernel.org/msg1939455.html) Change since v2: 1) Fix calculation of flush pages in the kvm_fill_hv_flush_list_func() 2) Change the logic of setting/clearing last_level flag Change since v1: 1) Make flush list as a hlist instead of list in order to keep struct kvm_mmu_page size. 2) Add last_level flag in the struct kvm_mmu_page instead of spte pointer 3) Move tlb flush from kvm_mmu_notifier_clear_flush_young() to kvm_age_hva() 4) Use range flush in the kvm_vm_ioctl_get/clear_dirty_log() Lan Tianyu (10): X86/Hyper-V: Add parameter offset for hyperv_fill_flush_guest_mapping_list() KVM/VMX: Fill range list in kvm_fill_hv_flush_list_func() KVM/MMU: Introduce tlb flush with range list KVM/MMU: Use range flush in sync_page() KVM/MMU: Flush tlb directly in the kvm_mmu_slot_gfn_write_protect() KVM: Add kvm_get_memslot() to get memslot via slot id KVM: Use tlb range flush in the kvm_vm_ioctl_get/clear_dirty_log() KVM: Add flush parameter for kvm_age_hva() KVM/MMU: Use tlb range flush in the kvm_age_hva() KVM/MMU: Add last_level flag in the struct mmu_spte_page arch/arm/include/asm/kvm_host.h | 3 +- arch/arm64/include/asm/kvm_host.h | 3 +- arch/mips/include/asm/kvm_host.h | 3 +- arch/mips/kvm/mmu.c | 11 ++++++-- arch/powerpc/include/asm/kvm_host.h | 3 +- arch/powerpc/kvm/book3s.c | 10 +++++-- arch/powerpc/kvm/e500_mmu_host.c | 3 +- arch/x86/hyperv/nested.c | 4 +-- arch/x86/include/asm/kvm_host.h | 11 +++++++- arch/x86/include/asm/mshyperv.h | 2 +- arch/x86/kvm/mmu.c | 55 ++++++++++++++++++++++++++++++------- arch/x86/kvm/mmu.h | 7 +++++ arch/x86/kvm/paging_tmpl.h | 5 ++-- arch/x86/kvm/vmx/vmx.c | 18 ++++++++++-- arch/x86/kvm/x86.c | 16 ++++++++--- include/linux/kvm_host.h | 1 + virt/kvm/arm/mmu.c | 13 +++++++-- virt/kvm/kvm_main.c | 51 ++++++++++++++-------------------- 18 files changed, 156 insertions(+), 63 deletions(-) -- 2.14.4
