Linux 内核堆栈打印函数

 

 

 

linux kernel 里面打印堆栈的函数

 

调用dump_stack()就会打印当前cpu的堆栈的调用函数了。参考内核源代码
arch/x86_64/kernel/traps.c


/*
* The architecture-independent dump_stack generator
*/
void dump_stack(void)
{
        unsigned long dummy;
        show_trace(&dummy);
}



        /*
         * When in-kernel, we also print out the stack and code at the
         * time of the fault..
         */
        if (in_kernel) {

                printk("Stack: ");
                show_stack(NULL, (unsigned long*)rsp);
