If you are using a Lenovo/Ideapad laptop sold before January 26, 2013 In Windows 7: You must use the Fn + F5 shortcut to bring up the "wireless device settings" switch interface to enable wireless devices. As shown in the following figure: The

Overview After the parsing of the kernel options is complete, the initialization of each subsystem enters the second part-the invocation of the entry function. Usually, USB, PCI subsystem will have a portal named Subsys_initcall, if you choose them

Fault symptom:The Fn and Ctrl functions of ThinkPad notebook can be set in the BIOS to meet different usage habits. In actual situations, after the E440 is set, the switching function cannot be implemented, for example, Fn + c cannot implement the

Now we are still wandering about the machine code. Yesterday we analyzed the code in arch/x86/kernel/head_32.s. The era of Assembly has passed. Now, all the code is C, nice. We are getting closer and closer to the base camp, and the device model is

As you write the C program needs to include the C library header file, Linux kernel programming also need to include kernel header files, most Linux drivers need to include the following three header files: #include #include #include The init.h

after the parsing of the kernel options is complete, the initialization of each subsystem enters the second part-the invocation of the entry function. Usually, USB, PCI subsystem will have a portal named Subsys_initcall, if you choose them as a

This article begins by analyzing the kernel's I2C subsystem. Description: 1. The kernel version of the analysis is 2.6.37.1 2. Development Board for TQ2440, onboard ARM9 (s3c2440) 3.I2C equipment for AT24C02 4. The sequence of analysis is the
