The x86 protection model is notoriously complex, with four privilege rings, segmentation, paging, call gates, task switches, and virtual 8086 mode. What's interesting from a hardware perspective is how the 386 manages this complexity on a 275,000-transistor budget. The 386 employs a variety of techniques to implement protection: a dedicated PLA for protection checking, a hardware state machine for page table walks, segment and paging caches, and microcode for everything else.

At this point, if I’m not confident that I can please anyone with my use of AI, then I’ll take solace in just pleasing myself. Continue open sourcing my projects, writing blog posts, and let the pieces fall as they may.
