A very basic microkernel. This isn't meant to be a full-featured kernel+OS, but as a test bed for understanding and implementing task scheduling (with daemon processes) and using ramdisks.

• Written in C++ and a small amount of ASM
  • C++14
  • NetWide ASM (NASM)
  • A very fragile, tiny version of libstd++ is included
    • std::vector
    • std::string
    • std::bitset
    • std::find / find_if / move / copy
    • [WIP] std::array
• GRUB2 bootloader
• Page tables
  • [TODO] processes have own CR3
• Memory management
  • Virtual Memory management
  • Heap manager (kernel only for the moment)
  • Physical Memory management
• Interrupts
  • Timer IRQ for sleep() and wait()
  • Keyboard IRQ for TTY input
  • Lock/Unlock the scheduler per thread
  • [TODO] Exception handling
• Higher-half kernel loading
• Time-slicing Scheduler
  • Multiple threads can run concurrently
    • Kernel is completely multithreaded
  • Per-thread stack space
  • [TODO] thread priorities
  • [TODO] per-process Page tables
• Starting to implement a TTY (future: POSIX compatibility)
• Filesystems
  • FAT16 (almost finished)
  • [TODO] ext2
• libcxxrt ported
  • allows C++ to use RTTI (for typeid and dynamic_cast)
  • try/catch exception handling is nearly implemented!
