I tried your 64bit grub.efi, same result - hangs at start (on current
imac8,1).
I wonder if you have tested on the current MacBook or MacBook Pro, perhaps
Apple have made another change. Also I dont have any info on previous Imac
models.
I was able to get a return via grub_main() only by excluding both of the
movq lines in the code before the call. Either one hangs it.
Looks to be a problem with grub_efi_image_handle and grub_efi_system_table?
-------------------
kern/x86_64/efi/startup.S
codestart:
call EXT_C(grub_main)
ret
- movq %rcx, EXT_C(grub_efi_image_handle)
- movq %rdx, EXT_C(grub_efi_system_table)
-----------------
kern/main.c
void
grub_main (void)
{
return;
}
---------------------
Is there anything else I can try?
