I don't really understand the kernel module process/policy - it was a lot of trying random things and seeing what worked. But I think you shouldn't need permission, as long as you're building it and running it on your own machine. But I do have an Apple developer account that costs money to let you develop on iOS, so that might have been a factor. You do need to disable some security features to run kernel modules. I'd rather be running this kind of instrumentation on Linux (or without a kernel, e.g. using m1n1), but I haven't set that up yet. (It'd be nice to lock the CPU to a frequency, and pin threads to cores, etc.)
