Somebody feel free to set me straight if I'm wrong (my knowledge of kernels is basically a college class and a half), but it seems the key thing here is that it's a kernel oriented around the L4 cache, which seems interesting because that's shared by the CPU and GPU: https://superuser.com/questions/1073937/what-does-l4-cache-hold-on-some-cpus https://superuser.com/questions/1073937/what-does-l4-cache-h... So, intuitively at least it seems it's for sharing the kernel workload with your GPU (supposing your hardware supports it)?
