This patch set implements a rudimentary, first version to get the ball going on that. With this applied, I can successfully run both Linux and Windows as guests, albeit with a few caveats: * no WFI emulation, a vCPU always uses 100% * vtimer handling is a bit hacky * we handle most sysregs flying blindly, just returning 0 * XHCI breaks in OVMF, works in Linux+Windows Despite those drawbacks, it's still an exciting place to start playing with the power of Apple Silicon. Enjoy!
