Changes since v1:
- Simplify PATCH4 by not using evmcs_get_supported_ctls() and doing more
macro magic to avoid having two evmcs_check_vmcs_conf{u32, u64} variants
[Sean]
This is a continuation of "KVM: VMX: Support updated eVMCSv1 revision + use
vmcs_config for L1 VMX MSRs" work:
https://lore.kernel.org/kvm/20220830133737.1539624-1-vkuznets@xxxxxxxxxx/
and a preparation to enabling new eVMCS features for Hyper-V on KVM, namely
nested TSC scaling.
Future proof KVM against two scenarios:
- nVMX: A new feature which doesn't have a corresponding eVMCSv1 field gets
implemented in KVM but EVMCS1_UNSUPPORTED_* defines are left unchanged.
- VMX: A new feature supported by KVM but currently missing in eVMCSv1 gets
implemented in a future Hyper-V version breaking KVM.
Note: 'vmx/evmcs.{c,h}' are renamed to 'vmx/hyperv.{c,h}' in
https://lore.kernel.org/kvm/20221004123956.188909-7-vkuznets@xxxxxxxxxx/
Vitaly Kuznetsov (4):
KVM: nVMX: Sanitize primary processor-based VM-execution controls with
eVMCS too
KVM: nVMX: Invert 'unsupported by eVMCSv1' check
KVM: nVMX: Prepare to sanitize tertiary execution controls with eVMCS
KVM: VMX: Resurrect vmcs_conf sanitization for KVM-on-Hyper-V
