[$] Hybrid scheduling gets more complicated

Just over ten years ago, the Arm big.LITTLE architecture posed a challenge for the kernel's CPUscheduler: how should processes be assigned to CPUs when not all CPUs havethe same capacity? The situation has not gotten simpler since then; newsystems bring new quirks that must be kept in mind for optimal scheduling.At the 2022 Linux Plumbers Conference, LenBrown and Ricardo Neri talked about Intel's hybrid systems and the workthat is being done to schedule properly on those systems.
