Booting

  • Implement versatile macros for debug output
  • Create helloworld kernel module, that would be able to load (NOTE: where? maybe 0x100000 (1mb) cause it always free(?)) either by bootx64.efi or by legacy bootloader (maybe requires some stub for setup before running kernel module). NOTE: define what kernel module expects (long mode? provided memory map? ) boot protocol
    ** Both legacy bootloader or efi boot stub will pass LFB to the kernel so it could set up writing text with custom font **

Kolibri64 kernel

  • Set up higher half. I.e map kernel to 0xFFFFFFFF80000000
  • Set up interrupts, cpu exceptions, ...
  • Set up SMP
  • ...

NOTE: firstly define what kernel module expects (long mode? provided memory map? ).

This is called a boot protocol. Here is the one from Linux as an example.
