Brief Introduction to interrupt handling for Linux Device Drivers The first step related to interrupt handling in Linux device drivers is to apply for and release IRQ APIs: request_irq () and free_irq (). The prototype of request_irq () is: Int request_irq (unsigned int IRQ, void (* Handler) (int irq, void * dev_id, s

The following code listing provides support for asynchronous notificationsA template for the device driver release () function.static int xxx_release (struct inode *inode, struct file *filp){struct Xxx_dev *dev = filp->private_data;/ * Remove the file from the asynchronous notification list */Xxx_fasync ( -1, FILP, 0); ...

, scheduling modes, and how to map them to the corresponding user space. It is equally important to port the RTOS hardware interface code to a more standardized Linux Device Driver in an I/O-intensive embedded program. This article will outline several common memory ing I/O methods that often appear in existing embedded applications. They cover a range from special use of interrupt service routines and access to hardware by user threads to a semi-sta

Because of work needs, now we need to learn the Linux Device Driver. Starting from the simplest character device driver, we need to record our learning experience and stick to our own ideas and conclusions. The makefile I wrote for the first hello World character driver is as follows: # Kvers = $ (shell uname-R) Ifneq ($ (kernelrelease ),) OBJ-M + = hello_world.o Else Kerdir =/usr/src/linux-headers-3.2.0-

Assuming that the transfer data between the hardware and the driver management is delayed for some reason, the driver author should implement buffering Data buffers help to separate the delivery and reception of data from the system call write and read, thereby improving the overall performance of the system A good buffering mechanism requires interrupt-driven I/O To properly interrupt-driven transmission data, the hardware should be able to generate interrupts acco
