linux wireless driver development tutorial

Linux driver development-I/O memory access process, driver development-I A device usually provides a set of registers to control the device, read/write devices, and obtain the device status, including the control registers, data registers, and status registers, which may be

files. The approximate process is as follows: After the system is started, the u-boot loads DTB, passes the DtB file to the kernel through the u-boot and the Linux kernel, then the kernel resolves the dtb file, according to the configuration in device tree (DTB file) to initialize the CPU pins of the device, the state of each peripheral. Device tree in the configuration is mainly played the role of initializing hardware resources, later can be in the

Mmap is a very important function.(4) When the application layer uses MMAP, then the virtual address space in the current application layer will be mapped with the actual memory physical address, that is, a part of the virtual address space FB, I operate the FB virtual address space is actually operating the memory of the physical address space is actually operating
