我想知道在内核模块中返回的API是什么&lt; VNOS - module.ko&GT;

从几个表格中了解到它不是那么直接,我们需要加载符号表来调试内核模块。

所以我所做的就是, 1.试图找到内核模块的.text .bss和.data节地址。 2.使用gdb中的add-symbol-file命令添加符号表文件。

但我收到错误说&#34;从/fabos/modules/vnos-module.ko ...处读取符号(找不到调试符号)......完成。&#34;

这里有什么我想念的吗?

root@sw0:/sys/module/vnos_module/sections# cat .text .data .bss 
0xf7f7f000
0xf7fb7a30
0xf7fc3da4

root@sw0:/sys/module/vnos_module/sections# gdb /fabos/modules/vnos-module.ko
