* feat(kprobe): Add basic kprobe support for x86_64 * feat: add ebpf support (DragonOS-Community#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

暂时通过条件编译的方式解决. 目前认为是鼠标驱动问题,没有正确判断是不是自己的数据... 但是因为我们场景下,鼠标驱动几乎用不到,因此先条件编译屏蔽. Signed-off-by: longjin <[email protected]>

…nity#949) ## 开发进展： ## namespace - pid_namespace 基本实现，基于pid_struct等数据结构实现隔离 - mnt_namespace 基本实现，挂载点的隔离通过不同的挂载树来实现 - usernamespace 作为支持性的namespace，目前受限实现全局静态 ## overlayfs - 实现若干个文件系统的叠加，在mount中传入多个路径作为多个fs的mount路径以及最后merge层的fs路径 - copy-up机制的，除最上层外其他层为只读层，满足写时拷贝，需要修改的时候copy到上层修改 - whiteout特殊文件，用于标记在下层需要被删除的文件用来掩盖需要删除的文件 ## cgroups - 目前cgroups还处于框架阶段，之后具体实现具体的内存、CPU等子系统
