/*
* Hyper-V device SSDT to disable unsupported devices under macOS on Windows Server 2019 / Windows 10 and newer.
*
* Windows 10 and newer define various objects conditionally, which are
* unsupported in older versions of macOS. All objects are enabled regardless
* of state in older versions, causing slow boot behavior and crashes during boot caused by AppleACPIPlatform.
*
* Windows 10 and newer also 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.
*
* This SSDT defines _STA methods for all affected objects and disables them entirely, or enables only if
* the approprate register is set (enabled in Hyper-V).
*
* On Windows Server 2012 R2 / Windows 8.1 and older this SSDT is unnecessary and can be disabled along with associated patches.
*
* Requires the following ACPI patches:
* (1) Base: \_SB.VMOD.TPM2
* Comment: _STA to XSTA rename (Hyper-V TPM)
* Count: 1
* Find: 5F535441 (_STA)
* Replace: 58535441 (XSTA)
* TableSignature: 44534454 (DSDT)
* (2) Base: \_SB.NVDR
* Comment: _STA to XSTA rename (Hyper-V NVDIMM)
* Count: 1
* Find: 5F535441 (_STA)
* Replace: 58535441 (XSTA)
* TableSignature: 44534454 (DSDT)
* (3) Base: \_SB.EPC
* Comment: _STA to XSTA rename (Hyper-V EPC)
* Count: 1
* Find: 5F535441 (_STA)
* Replace: 58535441 (XSTA)
* TableSignature: 44534454 (DSDT)
* (4) Base: \_SB.VMOD.BAT1
* Comment: _STA to XSTA rename (Hyper-V battery)
* Count: 1
* Find: 5F535441 (_STA)
* Replace: 58535441 (XSTA)
* TableSignature: 44534454 (DSDT)
