Question one: Why the device tree is needed. In the current widely used Linux kernel 2.6.x version, for different platforms, different hardware, there is often a large number of different, poor portability of the board level Description code to achieve these different platforms and different hardware special adaptation Demand. But too many platforms and different hardware have led to more and more such code, such as Arch/arm/plat-xxx and arch/arm/mach

Outdated devices will delay the speed of the system in some situations. Whenever the system adds new devices, the system will keep the device driver and device information for quick search next time, but this also brings about many problems, such as sometimes someone else's USB flash drive is used once, it will leave information; sometimes the old device informat

1. Call module_init (scull_init_module) in the insmod module. Let's take a look at this function: int scull_init_module (void) II, Int scull_init_module (void) The device has been initialized. Summarize the initialization steps of the module (only the general situation is taken into account, not the special case of Scull ). Step 1: dynamically generate the device ID.
