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.

It's a replacement for the decades-old IDT or Interrupt Descriptor Table that dates way back to the Intel 286 processor circa 1982. Both FRED and IDT are instructions for how to handle system events, such as a mouse input or the arrival of a network data packet, also known as interrupts.
