1. 解释“kernel null pointer dereference”错误含义 "kernel null pointer dereference" 是一个在Linux内核中常见的严重错误,通常意味着内核代码试图访问一个空(NULL)指针所指向的内存地址。在内核上下文中,这种访问是非法的,因为它试图读取或写入未分配的内存区域,导致系统安全性和稳定性受到威胁。因此,这种错误通常会...

Unable to handle kernel NULL pointer dereference at virtual address 00000000 原因: 因为我用到了中断,在中断函数中断我调用了一全局指针P,这个指针在定义时为NULL。 由于系统子注册玩中断后会马上检验中断函数,即使当前函数还没执行完。 这就带来了一个问题,在中断注册代码后面 才对P进行赋值,结果还没执行到赋值...
在你的程序中使用了空指针，检查下你的内存分配是否初始化了。你的代码在内核中依赖的模块是否全部勾选。
