X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=11c4b1ca719eaaa5ca6fe0e80bb009f3f2012fd2;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git kvm/x86: Hyper-V HV_X64_MSR_VP_INDEX export for QEMU. Insert Hyper-V HV_X64_MSR_VP_INDEX into msr's emulated list, so QEMU can set Hyper-V features cpuid HV_X64_MSR_VP_INDEX_AVAILABLE bit correctly. KVM emulation part is in place already. Necessary to support loading of winhv.sys in guest, which in turn is required to support Windows VMBus. Signed-off-by: Andrey Smetanin Reviewed-by: Roman Kagan Signed-off-by: Denis V.
