KFunc scx_bpf_cpu_to_cid
Return the cid for cpu.
Definition
Parameters
cpu: cpu to look up
Returns
Return the cid for cpu. Trigger scx_error and return -EINVAL if cpu is invalid. The cid<->cpu mapping is static for the lifetime of the loaded scheduler, so the BPF side can cache the result to avoid repeated kfunc invocations.
