## 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.
