I don't think any single piece of the KVM/ARM code ever generated as much hatred as the GIC emulation. It was written by someone who had zero experience in modeling hardware (me), was riddled with design flaws, should have been scrapped and rewritten from scratch long before having a remote chance of reaching mainline, and yet we supported it for a good three years. No need to mention the names of those who suffered, the git log is singing their praises. Thankfully, we now have a much more maintainable implementation, and we can safely put the grumpy old GIC to rest. Fellow hackers, please raise your glass in memory of the GIC: The GIC is dead, long live the GIC!
