Documents detailing technical aspects of what's thought to be its next-gen Zen 6 CPUs have been posted on AMD's website. The most significant covers AMD's adoption of Intel's so-called 'FRED' interrupt handling. It's a change that implies that Zen 6 could be a major architectural overhaul as opposed to a relatively minor revision.
FRED stands for Flexible Return and Event Delivery. At least, that's what it stands for now. No lesser an authority than Linux creator Linus Torvalds has something to say about that, more on which in a moment.
