24 | /*␊ |
25 | * Modern Darwin kernels require some amount of EFI because Apple machines all␊ |
26 | * have EFI. Modifying the kernel source to not require EFI is of course␊ |
27 | * possible but would have to be maintained as a separate patch because it is␊ |
28 | * unlikely that Apple wishes to add legacy support to their kernel.␊ |
29 | *␊ |
30 | * As you can see from the Apple-supplied code in bootstruct.c, it seems that␊ |
31 | * the intention was clearly to modify this booter to provide EFI-like structures␊ |
32 | * to the kernel rather than modifying the kernel to handle non-EFI stuff. This␊ |
33 | * makes a lot of sense from an engineering point of view as it means the kernel␊ |
34 | * for the as yet unreleased EFI-only Macs could still be booted by the non-EFI␊ |
35 | * DTK systems so long as the kernel checked to ensure the boot tables were␊ |
36 | * filled in appropriately.␉Modern xnu requires a system table and a runtime␊ |
37 | * services table and performs no checks whatsoever to ensure the pointers to␊ |
38 | * these tables are non-NULL. Therefore, any modern xnu kernel will page fault␊ |
39 | * early on in the boot process if the system table pointer is zero.␊ |
40 | *␊ |
41 | * Even before that happens, the tsc_init function in modern xnu requires the FSB␊ |
42 | * Frequency to be a property in the /efi/platform node of the device tree or else␊ |
43 | * it panics the bootstrap process very early on.␊ |
44 | *␊ |
45 | * As of this writing, the current implementation found here is good enough␊ |
46 | * to make the currently available xnu kernel boot without modification on a␊ |
47 | * system with an appropriate processor. With a minor source modification to␊ |
48 | * the tsc_init function to remove the explicit check for Core or Core 2␊ |
49 | * processors the kernel can be made to boot on other processors so long as␊ |
50 | * the code can be executed by the processor and the machine contains the␊ |
51 | * necessary hardware.␊ |
