feat(ebpf):[WIP] add eBPF support (#948)
* feat(kprobe): Add basic kprobe support for x86_64 * feat: add ebpf support (#912) - 实现bpf()一部分命令,包括几种基本map,相关的helper函数 - 实现部分perf相关的数据结构 - 暂时为文件实现简单mmap - 实现一个使用kprobe统计syscall 调用次数的ebpf程序 对eBPF支持程度(基本): - 简单的eBPF程序(没有指定特殊的Map) - 使用内核已经实现的Map的eBPF程序 - 可以和kprobe配合使用 - 内核Map相关的接口定义已经实现,添加新的Map较为简单 不支持的功能: - 区分不同的eBPF程序类型(Network/Cgroup)并限定可调用的helper函数集 - 与内核其它跟踪机制配合(tracepoint) - 其它helper和Map todo - [ ] 修改mmap,需要讨论,因为这个和块缓存层相关 - [x] 添加文档 - [x] 修复可能的错误 - [x] 增加rbpf版本信息 * feat: add /sys/devices/system/cpu/possible file * feat: add /sys/devices/system/cpu/online
