KFunc scx_bpf_nr_online_cids
Return current count of online CPUs in cid space.
Definition
Returns
Return num_online_cpus. The standard model restarts the scheduler on hot-plug, which lets schedulers treat [0, nr_online_cids) as the online range. Schedulers that prefer to handle hotplug without a restart should install a custom mapping via scx_bpf_cid_override and track onlining through the ops.cid_online / ops.cid_offline callbacks.
