xnu's Issues

Platform missing

I'm not completely sure but I think we need some kexts.

After

Reading startup extensions.
Loading Kernel External Components.
Reading built-in kernel personalities for I/O Kit drivers.
Sending all eligible registered kexts' personalities to the IOCatalogue but not starting matching.
0 kext personality sent to the IOCatalogue; matching not started.

Kernel panics with

panic(cpu 0 caller 0xfffffff00785dd0c): "Unable to find driver for this platform: \"~~~~~~~~~~~~~~~~~~~~~~~~\".\n"

Do you guys think this is the kernel asking us for the basic kexts or is it something else?

RPI 4 compatibility

I'm very interested in this project and I was wondering if this could run on the BCM2711, Raspberry Pi 4

Pull requests/Todo list?

Great project :)
I really like the idea of it, and it honestly feels like darwin-on-arm is sorta coming back.
I was wondering if you had a todo list of things that should be implemented (such as filling in functions that were "stubbed" out) and perhaps building a toolchain to compile on *nix.

Also: you accepting pull reqs? :P

Help needed with Qemu

Currently we are able to build a mach0 binary, the boot process starts but panics everywhere... If you have experience with lldb please PM @abradleyuno on twitter.
