An in-depth discussion of Linux driver technology (4)_The implementation principles and related technologies of asynchronous notification technology
Article Introduction:In the process of writing Linux drivers, asynchronous notification technology is a very important technology. It can achieve efficient event processing and data transmission, improving system performance and response speed. In this article, we will delve into the implementation principles and related technologies of Linux driver technology (4)_asynchronous notification technology. The full name of asynchronous notification is "signal-driven asynchronous IO". Through the "signal" method, when the resources expected to be obtained are available, the driver will actively notify the specified application, corresponding to the "signal" of the application layer. What is used here is Signal "SIGIO". The operation step is for the application layer program to register itself as a process driver that receives the SIGIO signal from the device file and implement the corresponding interface, in order to have the ability to receive this device from all registered devices.
