I had to read this twice before I understood the real contents.
Let's please leave the sarcasm out of our postings? .. it doesn't add
anything to a technical discussion.
"The reference MMU is different from the MMU that Sun has been
using in most of its SPARC based products. I don't quite see
the problem with this. A well written operating system only
requires a change to a single driver to port it to a new MMU."
An MMU is not a "device," to be "driven" easily by a single module.
Big MMU differences cause ripples throughout the kernel, and in extreme
cases can affect user code.
