ExectOS Ideas
This is a list of ideas that migh but not must be realized.
SDK
- Currently XT Development Kit (XTDK) is a garbage. It should be cleaned up the way, it contains all structures and definitions, as well as all routines that are exported and can be used by other components or software dynamically linked. All other routines should be available as well in some form, as some libraries can share code with others (eg. XTLDR calls routines exported by XTOSKRNL). This is partially done, as XTDK has been cleaned up, but still there are routines used by XTLDR.
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.
- Design a mechanism of sharing common code between some architectures (i.e. both i686 and amd64 supports APIC, while it is not available on ARM).
- Finish framebuffer and terminal implementation. Initialization code is already prepared as well as routines for clearing the screen and drawing single points. Terminal should be instantiable (should be able to create many terminals and switch between them) and work on top of FB. It should define ANSI colors and scrollback buffer.
