[PATCH hyperv-next v8 02/11] arm64: hyperv: Use SMCCC to detect hypervisor presence

2025-04-14 Thread Roman Kisel
The arm64 Hyper-V startup path relies on ACPI to detect running under a Hyper-V compatible hypervisor. That doesn't work on non-ACPI systems. Hoist the ACPI detection logic into a separate function. Then use the vendor-specific hypervisor service call (implemented recently in Hyper-V) via SMCCC in
