Now that Apple Silicon is widely available, people are obviously excited to try and run virtualized workloads on them, such as Linux and Windows.
This patch set implements a fully functional version to get the ball going on that. With this applied, I can successfully run both Linux and Windows as guests. I am not aware of any limitations specific to Hypervisor.framework apart from: - gdbstub debugging (breakpoints) - missing GICv3 support - Windows will not work due to UDEF SMC implementation To use hvf support, please make sure to run -M virt,highmem=off to fit in M1's physical address space limits and use -cpu host. Enjoy!
