ExectOS Ideas

This is a list of ideas that migh but not must be realized.

XTLDR

  • Rewrite memory mapping and paging support in bootloader to make it more flexible and architecture independent. This should support paging levels, thus allowing to make a use of PML5 on modern AMD64 processors and increasing the addressable virtual memory from 256TB to 128PB.
  • Find graphics card from all PCI devices and identify its framebuffer address when GOP is not supported by UEFI firmware and UGA has to be used instead.

XTOSKRNL

  • Implement mechanism for detecting CPU features and checking hardware requirements. If CPU does not meet requirements, it should cause a kernel panic before any non-supported instruction is being used.
