| 36 | * Modern Darwin kernels require some amount of EFI because Apple machines all␊ |
| 37 | * have EFI. Modifying the kernel source to not require EFI is of course␊ |
| 38 | * possible but would have to be maintained as a separate patch because it is␊ |
| 39 | * unlikely that Apple wishes to add legacy support to their kernel.␊ |
| 40 | *␊ |
| 41 | * As you can see from the Apple-supplied code in bootstruct.c, it seems that␊ |
| 42 | * the intention was clearly to modify this booter to provide EFI-like structures␊ |
| 43 | * to the kernel rather than modifying the kernel to handle non-EFI stuff.␉ This␊ |
| 44 | * makes a lot of sense from an engineering point of view as it means the kernel␊ |
| 45 | * for the as yet unreleased EFI-only Macs could still be booted by the non-EFI␊ |
| 46 | * DTK systems so long as the kernel checked to ensure the boot tables were␊ |
| 47 | * filled in appropriately.␉ Modern xnu requires a system table and a runtime␊ |
| 48 | * services table and performs no checks whatsoever to ensure the pointers to␊ |
| 49 | * these tables are non-NULL.␉Therefore, any modern xnu kernel will page fault␊ |
| 50 | * early on in the boot process if the system table pointer is zero.␊ |
| 51 | *␊ |
| 52 | * Even before that happens, the tsc_init function in modern xnu requires the FSB␊ |
| 53 | * Frequency to be a property in the /efi/platform node of the device tree or else␊ |
| 54 | * it panics the bootstrap process very early on.␊ |
| 55 | *␊ |
| 56 | * As of this writing, the current implementation found here is good enough␊ |
| 57 | * to make the currently available xnu kernel boot without modification on a␊ |
| 58 | * system with an appropriate processor. With a minor source modification to␊ |
| 59 | * the tsc_init function to remove the explicit check for Core or Core 2␊ |
| 60 | * processors the kernel can be made to boot on other processors so long as␊ |
| 61 | * the code can be executed by the processor and the machine contains the␊ |
| 62 | * necessary hardware.␊ |
