15 ## kprobe工作流程
21 1. 注册kprobe后，注册的每一个kprobe对应一个kprobe结构体，该结构中记录着探测点的位置，以及该探测点本来对应的指令。
22 2. 探测点的位置被替换成了一条异常的指令，这样当CPU执行到探测点位置时会陷入到异常态，在x86_64上指令是int3（如果kprobe经过优化后，指令是jmp）
23 3. 当执行到异常指令时，系统换检查是否是kprobe 安装的异常，如果是，就执行kprobe的pre_handler,然后利用CPU提供的单步调试（single-step）功能，设置好相应的寄存器…
25 5. 当卸载kprobe时，探测点原来的指令会被恢复回去。
31 ## kprobe的接口
35 pub fn unregister_kprobe(kprobe: LockKprobe) -> Result<(), SystemError>;
55 - `disable` 和 `enable` 用于动态关闭kprobe，在`disable`调用后，kprobe被触发时不执行回调函数

| H A D | index.rst | 4 …内核跟踪机制由很多功能构成， 比如kprobe/uprobe/tracepoint/ftrace等， 以及用于扩展内核可观测性的eBPF，内核当前支持kprobe和eBPF， 本章将介绍这两种机制。

| H A D | eBPF.md | 31 1. 内核会根据用户请求，将eBPF程序附加到内核的挂载点上(kprobe/uprobe/trace_point)
102 1. kprobe实现：位于目录`kernel/crates/kprobe`
238 联通eBPF和kprobe的系统调用是[`perf_event_open`](https://man7.org/linux/man-pages/man2/perf_event_open.2.html…
245 // See /sys/bus/event_source/devices/kprobe/type
247 let kprobe_event = kprobe::perf_event_open_kprobe(args);
264 - `PERF_TYPE_MAX` 通常指示创建kprobe/uprobe事件，也就是用户程序使用kprobe的途径之一，用户程序可以将eBPF程序绑定在这个事件上
