Why not.. MINIX?

• dalke 12y ago
  Quoting from the Xv6 web page, "Adding multiprocessor support requires handling concurrency head on with locks and threads (instead of using special-case solutions for uniprocessors such as enabling/disabling interrupts) and helps relevance." MINIX didn't have multiprocessor support until MINIX 3. Unlike MINIX 2, MINIX 3 is not designed as a teaching OS.

  It wouldn't be a bad idea to use both. It could be nice to study a monolithic kernel-based OS (xv6) and a microkernel-based OS (MINIX). In 6.828, we read xv6, and we implemented parts of JOS, which is exokernel-based. Since exokernels are kind of like microkernels on steroids, I suppose it makes sense that we didn't focus on normal microkernels too much.
