KFunc scx_bpf_get_idle_cpumask
This function gets a referenced kptr to the idle-tracking per-CPU cpumask.
Definition
Returns
NULL if idle tracking is not enabled, or running on a UP kernel.
Signature
const struct cpumask *scx_bpf_get_idle_cpumask()
Note
This kfunc returns a pointer to a refcounted object. The verifier will then ensure that the pointer to the object
is eventually released using a release kfunc, or transferred to a map using a referenced kptr
(by invoking bpf_kptr_xchg). If not, the verifier fails the
loading of the BPF program until no lingering references remain in all possible explored states of the program.
