svm->vmcb will now point to either a separate vmcb L1 ( not nested ) or L2 vmcb ( nested ).
Changes: v2 -> v3 - Added vmcb switching helper. - svm_set_nested_state always forces to L1 before determining state to set. This is more like vmx and covers any potential L2 to L2 nested state switch. - Moved svm->asid tracking to pre_svm_run and added ASID set dirty bit checking. v1 -> v2 - Removed unnecessary update check of L1 save.cr3 during nested_svm_vmexit. - Moved vmcb01_pa to svm. - Removed get_host_vmcb() function. - Updated vmsave/vmload corresponding vmcb state during L2 enter and exit which fixed the L2 load issue. - Moved asid workaround to a new patch which adds asid to svm. - Init previously uninitialized L2 vmcb save.gpat and save.cr4 Tested: kvm-unit-tests kvm self tests Loaded fedora nested guest on fedora Cathy Avery (2): KVM: SVM: Track asid from vcpu_svm KVM: SVM: Use a separate vmcb for the nested L2 guest arch/x86/kvm/svm/nested.c | 125 ++++++++++++++++++-------------------- arch/x86/kvm/svm/svm.c | 58 +++++++++++------- arch/x86/kvm/svm/svm.h | 51 +++++----------- 3 files changed, 110 insertions(+), 124 deletions(-) -- 2.20.1
