So, essentially, you're just doing cache eviction in software. That's obviously a lot of overhead, but at least it gives you eviction control. However, there is very little to do when it comes to cache eviction. The algorithms are all well known and there is little innovation in that space. So baking that into the hardware is always better, for now.
