[[文件:范例.jpg]]
1. find the address of function
<source lang="c">
cd KIRNEL_DIR
cat System.map |grep "function name"
</source>
2. calculate pc absolute address, in my case:
   ffff800010b7a2a0 + 0x210 = ffff800010b7a4b0
3. find the line of source code
<source lang="c">
aarch64-linux-gnu-addr2line  -e vmlinux <absolute address>
</source>
