FreeBSD Scheduling on Hybrid CPUs
Scheduling on Hybrid CPUs
Implement policies to steer scheduling decisions as the user/admin sees fit, with different possible goals (e.g., max performance, energy savings, latency, etc.). Processes/threads that should never consume too much power or, in the case of Meteor Lake, should not wake the compute tile, would be put in an appropriate cpuset whose policy completely rules out running on anything else than the most efficient cores. If that problem can't be solved this way, then such applications just will have to be put in a cpuset that only includes cores of a single type providing enough computing power for the task.
