  • Refactor and improve memory management and heap allocation (sbrk, malloc, free etc)
  • Improving x86 paging and frame mapping/allocation
  • Implement Virtual File System and ext2/custom-fs implementation
  • Fix build system to move away from iso to a real HDD
  • Init ramdisk
  • Implement multitasking, COW, processes (fork etc)
  • Implement scheduler for user processes
  • Usermode apps: init, shell, fs related (mkdir, ls etc), cat, echo, etc.
  • Support multiple cpus/core, SMP
