Character Device Control TechnologyIn front of the study, we learned the driver, to realize the program read and write function. Now the device has a more important function-control.Functions for controlling devices: IOCTL.CMD: The parameter is a command we send, such as a reboot.The third parameter: is dependent on the second, for example we want to modify the b

locks and semaphores take the form of "get lock-access critical section-release lock".*************************************************************************************************************** **********5. MutexThe mutex and the semaphore are basically the same. Not introduced.Summary: Concurrency and race are widespread, these mechanisms are a good way to solve the problem, interrupt masking is rarely used alone, atomic operations can only be done for integers, so the spin lock and signal
