An "oops" is what the kernel throws at us when it finds something faulty, or an exception, in the kernel code. it's somewhat like the segfaults of user-space. an oops dumps its message on the console; it contains the processor status and the CPU registers of when the fault occurred. the offending process that triggered this oops gets killed without releasing lock

Most bugs describe null pointers or use other incorrect pointer values to express themselves. Such Bugs usually output a oops message. Any address used by the processor is almost a virtual address, which is mapped to a physical address through a complex page table structure (except the physical address used by the memory management subsystem ). when an Invalid Pointer is referenced, the paging mechanism cannot map the pointer to a physical address, an

We probably talked about how to write a simple character device driver, we are not God, writing code will definitely have problems, we need to write code in the process of constant debugging. In a normal C application, we often use printf to output information, or use GDB to debug a program, so how does the driver debug it? We know that when debugging the program often encountered problem is the wild pointer or array out of the problem, run this program in the application will be reported segmen
