Last change on this file since 35 was 35, checked in by max@…, 5 years ago

Update:

  • Introduce a basic VM manager in hal_gpt.c, to create the initial page tree for cluster0.
  • Locate the ACPI RSDP table, which involves entering the PA into cluster0's VA space.

The definitions are still a bit messy, but they will be reorganized later.
