kallsyms_lookup_name Lookup the address for this symbol. Returns 0 if not found. kallsyms_on_each_symbol kallsyms_lookup Lookup an address* - modname is set to NULL if it's in the kernel.* - We guarantee that the returned name is valid until we reschedule even if.* It resides in ...
一般来说,内核只会导出由EXPORT_PARM宏(如EXPORT_SYMBOL_GPL、EXPORT_SYMBOL等)指定的符号给模块使用。为了使debugger提供更好的调试功能,需要使用kallsyms工具为内核生成__kallsyms段数据,该段描述所有不处在堆栈上的内核符号。这样debugger就能更好地解析内核符号,而不仅仅是内核指定导出的符号。 二. kallsyms有什么用...
