Subject: [PATCH v3 2/7] Drivers: hv: Enable VTL mode for arm64
Date: Fri, 26 Jul 2024 15:59:05 -0700 [thread overview]
Message-ID: <20240726225910.1912537-3-romank@linux.microsoft.com> (raw)
In-Reply-To: <20240726225910.1912537-1-romank@linux.microsoft.com>
Kconfig dependencies for arm64 guests on Hyper-V require that be ACPI enabled,
and limit VTL mode to x86/x64. To enable VTL mode on arm64 as well, update the
dependencies. Since VTL mode requires DeviceTree instead of ACPI, don’t require
arm64 guests on Hyper-V to have ACPI.
