Skb_release_data function has 0xc4 so large, and oops occurs at 0x74 place. So let's take a look at where the Skb_release_data starts:#grep Skb_release_data./system.mapC0282AF4 T Skb_release_dataSo we know that when the system error occurs, the program pointer is c0282af4+0x74=c0282b68(2) Then use GDB to view the GDB./vmlinux (executed under the Linux directory) and enter debug mode.gdb$ b *0xc0282b68Breakpoint 1 at 0xc0282b68:file NET/CORE/SKBUFF.C, line312This is to tell us in which file, in

With this simple example code, we further clarify how the drive works.4, good, ready to work to complete, here should formally start. Write it yourself? No, or secretly lazy, online to find ready-made, there is just your chip driver, really lucky, direct use, of course, often can not be used directly, to debug under the next line.

int Dma_map_device (struct device *dev,struct scatterlist *sg, int nents,enum dma_data_directiondirection); There can be a relatively simple way to pre-allocate buffers in a Linux system, which is to synchronize the "mem=" parameter to reserve memory. For example, for a system with a memory of 64MB, passing the MEM=62MB command-line argument to it allowsThe top 2MB memory is reserved for use as IO memory, this 2MB memory can be statically mapped, can also execute Ioremap ().As wi

If the implementation of a function of the inherited object is the same as that of the base class, it can directly inherit the functions of the base class. On the contrary, it can be overloaded. This object-oriented design method greatly improves the code reusable ab

From one point of view, the role of a device driver is to provide a mechanism, not a policy. When writing drivers, programmers should pay particular attention to the following basic concept: When writing kernel code to access hardware, do not impose any specific policy on the user. Because different users have different needs, the driver should handle the problem of how to make the hardware available, and how to use the hardware problem left to the up
