[Qemu-devel] [PATCH v2 0/9] i386/kvm/hyper-v: refactor and implement 'hv-stimer-direct' and 'hv-passthrough' enlightenments |

It has been a while since my 'v1' and I (again) apologize for that.
Changes since v1:
- Existing Hyper-V properties are converted from BOOL to BIT64, this allows
us to express dependencies between them in a more natural way as well as
simplifies search in kvm_hyperv_properties [Roman Kagan] (hope I got the
idea right, but in any case this should be an improvement). PATCH1 added
to the series.
- 'hv-all' renamed to 'hv-passthrough' [Roman Kagan]
- minor changes mostly related to support the addition of PATCH1.
Original description:
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.
Vitaly Kuznetsov (9):
i386/kvm: convert hyperv enlightenments properties from bools to bits
i386/kvm: add support for KVM_GET_SUPPORTED_HV_CPUID
i386/kvm: move Hyper-V CPUID filling to hyperv_handle_properties()
i386/kvm: document existing Hyper-V enlightenments
i386/kvm: implement 'hv-passthrough' mode
i386/kvm: hv-stimer requires hv-time and hv-synic
i386/kvm: hv-tlbflush/ipi require hv-vpindex
i386/kvm: hv-evmcs requires hv-vapic
i386/kvm: add support for Direct Mode for Hyper-V synthetic timers
