Patience, my friend. We're not quite there yet with this tutorial. We don't need sfence.vma for what I've covered here. Plus, there are about four ways to use the sfence.vma instruction (whether or not rs1 is zero or not and if rs2 is zero or not). I'd like to have some context behind each one of these four cases, but I can't do that in the OS's current state.
