[PATCH 2/2] hyperv: Support hv-xmm-input enlightenment
Posted by Tim Wiederhake 3 months, 1 week ago 
qemu supports this enlightenment since version 7.10.

From the qemu commit:
    Hyper-V specification allows to pass parameters for certain hypercalls
    using XMM registers ("XMM Fast Hypercall Input"). When the feature is
    in use, it allows for faster hypercalls processing as KVM can avoid
    reading guest's memory.
