看起來是在寫 kernel，但其實都在自幹 STL...

• Lab1: Hello World
• Lab2: Booting (bootloader)
• Lab3: Allocator (pmm)
• Lab4: Exception and Interrupt Handling
• Lab5: Multitasking
• Lab6: Virtual Filesystem
• Lab7: Filesystem Meets Hardware
• Lab8: Virtual Memory (vmm)

• I/O: MiniUART - supports sync/async I/O
• ARM Mailbox API
• Exception & interrupt handling - top/bottom halves, tasklets
• Buddy allocator
• Dynamic allocator - my own optimized SLOB allocator (a simplified ptmalloc)
• Boot memory allocator
• User / Kernel threads
• Multitasking - sys_fork(), sys_exec(), sys_wait(), sys_exit()
• User tasks preemption
• Kernel preemption - protect critical sections
• POSIX signals and custom signal handlers - sys_kill(), sys_signal(), sys_rt_sigreturn()
• Wait Queues
• tmpfs
• Virtual filesystem - vfs_open(), vfs_close(), vfs_write(), vfs_read()
• System-wide opened file table, Per-process file descriptor tables
• POSIX file I/O - sys_read(), sys_write(), sys_open(), sys_close()
• Multi-level VFS
• Procfs
• ...

• Algorithm
• Concepts
• Functional
• Iterator
• UniquePtr + make_unique<>()
• SharedPtr + make_shared<>() + *_pointer_cast<>()
• WeakPtr
• List
• String
• Vector (?)
• Deque (the performance is shit ...)
• Utility (move and forward)
• ...
