Name:pf_prog_select_runtime - select exec runtime for BPF program*@fp: bpf_prog populated with internal BPF program*@err: pointer to error variable* Try to JIT eBPF program, if JIT is not available, use interpreter.

Proto:struct bpf_prog *bpf_prog_select_runtime(struct bpf_prog *fp, int *err)

Type:struct bpf_prog

Parameter:

TypeParameterName
struct bpf_prog *fp
int *err

1798  If err Then Return fp
1801  fp = Stub for JITs that only support cBPF. eBPF programs are interpreted.* It is encouraged to implement bpf_int_jit_compile() instead, so that* eBPF and implicitly also cBPF can get JITed!
