37 * Modern Darwin kernels require some amount of EFI because Apple machines all␊
38 * have EFI. Modifying the kernel source to not require EFI is of course␊
39 * possible but would have to be maintained as a separate patch because it is␊
40 * unlikely that Apple wishes to add legacy support to their kernel.␊
41 *␊
42 * As you can see from the Apple-supplied code in bootstruct.c, it seems that␊
43 * the intention was clearly to modify this booter to provide EFI-like structures␊
44 * to the kernel rather than modifying the kernel to handle non-EFI stuff.␉ This␊
45 * makes a lot of sense from an engineering point of view as it means the kernel␊
46 * for the as yet unreleased EFI-only Macs could still be booted by the non-EFI␊
47 * DTK systems so long as the kernel checked to ensure the boot tables were␊
48 * filled in appropriately.␉ Modern xnu requires a system table and a runtime␊
49 * services table and performs no checks whatsoever to ensure the pointers to␊
50 * these tables are non-NULL.␉Therefore, any modern xnu kernel will page fault␊
51 * early on in the boot process if the system table pointer is zero.␊
52 *␊
53 * Even before that happens, the tsc_init function in modern xnu requires the FSB␊
54 * Frequency to be a property in the /efi/platform node of the device tree or else␊
55 * it panics the bootstrap process very early on.␊
56 *␊
57 * As of this writing, the current implementation found here is good enough␊
58 * to make the currently available xnu kernel boot without modification on a␊
59 * system with an appropriate processor. With a minor source modification to␊
60 * the tsc_init function to remove the explicit check for Core or Core 2␊
61 * processors the kernel can be made to boot on other processors so long as␊
62 * the code can be executed by the processor and the machine contains the␊
63 * necessary hardware.␊
