Is there a nice xv6 equivalent for x86_64? How do MIT students learn about 64-bit arch?

This was good, but it leaves a lot out. No mention of kernel space.

You will probably find an x86_64 port of xv6 on GitHub. IMHO, there is nothing terribly special about x86_64. The goal of xv6 is not to teach 64-bit computers, but to cover operating system basics (primarily multitasking, virtual memory and filesystems).
