[Qemu-devel] [PATCH RFC 0/8] i386/kvm/hyper-v: refactor and implement 'hv-stimer-direct' and 'hv-all' enlightenments |
Date: |

The recently introduced Direct Mode for Hyper-V synthetic timers
enlightenment is only exposed through KVM_GET_SUPPORTED_HV_CPUID ioctl.
Take the opportunity and re-implement the way we handle Hyper-V
enlightenments in QEMU, add support for hv-stimer-direct and 'hv-all'
pass-through mode, add missing dependencies between enlightenments.
RFC: we could've been more conservative and only use
KVM_GET_SUPPORTED_HV_CPUID for new enlightenments. I'd also like to know
what you think about the 'pass-through' approach taken to implement
'hv-all' mode: we could've kept QEMU filling in signature, vendor,...
but we take CPUIDs passed by KVM 'as-is'.
Vitaly Kuznetsov (8):
Update linux headers (5.0-rc2)
i386/kvm: add support for KVM_GET_SUPPORTED_HV_CPUID
i386/kvm: move Hyper-V CPUID filling to hyperv_handle_properties()
i386/kvm: Implement 'hv-all' pass-through mode
i386/kvm: hv-evmcs requires hv-vapic
i386/kvm: hv-stimer requires hv-time and hv-synic
i386/kvm: hv-tlbflush/ipi require hv-vpindex
i386/kvm: add support for Direct Mode for Hyper-V synthetic timers
