/*
 * Hyper-V CPU SSDT to enable proper CPU detection under macOS.
 *
 * Windows 10 and newer use ACPI0007 Device objects for CPUs, which macOS cannot detect.
 * This SSDT redefines the first 64 as Processor objects.
 * This may cause issues with other operating systems.
 *
 * On Windows 8.1, the objects defined here will conflict with the existing
 * objects preventing two sets of Processor objects from being loaded.
