KFunc scx_bpf_this_cid
Return the cid of the CPU this program is running on.
Definition
cid-addressed equivalent of bpf_get_smp_processor_id for scx programs. The current cpu is trivially valid, so this is just a table lookup.
Returns
Return the cid of the CPU this program is running on. Return -EINVAL if called from a non-SCX program before any scheduler has ever been enabled (the cid table is still unallocated at that point).
Signature
s32 scx_bpf_this_cid()
