Phoronix: Linux Patches Updated For Sapphire Rapids C0.x Idle States
While Intel has been working on the Sapphire Rapids support for Linux going back years and to other key components like GCC and LLVM/Clang to provide for a good at-launch experience with 4th Gen Xeon Scalable processors, one bit that they hadn't squared away in advance of launch has been the new C0.x idle states.
