Linux Driver Poll Example at Jesus Clancy blog

Linux Driver Poll Example. Both allow a process to determine whether it can read from or write to one or more open files without blocking. Applications that use nonblocking i/o often use the poll and select system calls as well. Understand basic concepts about linux device drivers and practical examples for understanding device drivers in linux. For example, let’s say we need to write a driver which counts number of pulses which occured on a certain gpio. It can be used either as an edge or level triggered interface and scales well to large numbers of watched file descriptors. I have a simple character device driver that allows you to read from a custom hardware. Poll and select have essentially the same functionality: If you need to implement a passive wait (not wasting cpu cycles while sensing the character device), you must. Implementing poll in a linux kernel module. Epoll is an event poll and a variant of poll. The driver is used for some sort of metering application where. Here we try to describe the linux post system call from both the client and the device driver perspective.
