Linux drivers-concurrency and normalitySequential-Multiple user-space programs that are running may access our code in a surprisingly combined way. SMP systems can even execute our code on different processors at the same time. Kernel code can be

Asynchronous notifications:The user program needs to complete two steps:1, the owner of the main process is specifiedUsing the FCNTL system call F_setown, the process ID of the main process is saved in Filp->f_owner 2, the asynchronous notification

Empowerment and restricted operationsAll-in-one operation can be found in , which contains ownership energy that the system can understand, without modifying the kernel source code, and the power to the driver developers is as

Measure time DifferenceClock interrupts are generated by timed hardware at periodic intervals, which are set by the kernel according to the Hz value, which is an architecture-related constant defined in the file associated with or one of the
