No. I was just trying to find out if Linux is supported on this target. The Linux implementation for ARM64 requires the SPCR table.[1][2] So it missing makes the platform kind of unsupported. A, okay, yeah I see. Thanks! (I was excited with it running and I didn't notice.) I'll follow up on this.

Bug#1007023: Please can you enable HyperV kconfig options for arm64 kernel?
Package: src:linux Version: 5.16.11-1 Hello, HyperV guest support has recently landed in the arm64 kernel. Could you please enable this in Debian Kernels (5.16+) via the following Kconfig options? CONFIG_FB_HYPERV=m CONFIG_HID_HYPERV_MOUSE=m CONFIG_HYPERV_BALLOON=m CONFIG_HYPERV_KEYBOARD=m CONFIG_HYPERV=m CONFIG_HYPERV_NET=m CONFIG_HYPERV_STORAGE=m CONFIG_HYPERV_UTILS=m CONFIG_HYPERV_VSOCKETS=m For testing purposes, one should run a recent "Windows Insider" build on their device for this functionality to work properly. I've created a Debian test kernel with the above options and was able to install/use Debian under HyperV. Cheers! -- Steve
