111 1. 增加bpf to bpf call 的支持：通过增加新的栈抽象和保存和恢复必要的寄存器数据
119 eBPF相关的系统调用都集中在`bpf()` 上，通过参数cmd来进一步区分功能，目前对其支持如下:
122 pub fn bpf(cmd: bpf_cmd, attr: &bpf_attr) -> Result<usize> {
137 error!("bpf cmd {:?} not implemented", cmd);
141 unimplemented!("bpf cmd {:?} not implemented", ty)
164 error!("bpf map type {:?} not implemented", map_meta.map_type);
251 // For bpf prog output
257 let bpf_event = bpf::perf_event_open_bpf(args);
263 - 其中一个`PERF_TYPE_SOFTWARE`是用来创建软件定义的事件，`PERF_COUNT_SW_BPF_OUTPUT` 确保这个事件用来采集bpf的输出。
