Linux driver programming can use multi-threading, depending on the specific application scenario. If the driver needs to handle multiple concurrent tasks or events at the same time, then multi-threading is necessary and can process multiple data packets at the same time. transmission and reception to improve efficiency.
The operating system of this tutorial: Linux5.18.14 system, Dell G3 computer.
Whether multi-threading is needed in Linux driver programming depends on the specific application scenario.
If the driver needs to handle multiple concurrent tasks or events at the same time, then multi-threading is necessary.
For example, in a network device driver, you may need to handle the transmission and reception of multiple data packets at the same time. In this case, you need Use multithreading to improve efficiency.
Multi-threading has the following benefits:
Improve system throughput: During the process of performing I/O operations, the CPU wastes a lot of time waiting for the I/O to complete. Multi-threading can make full use of CPU resources and improve system throughput.
Improved interactivity: Multithreading provides a good user experience (such as fast response times) because threads can perform multiple operations at the same time without having the user wait for a single thread to complete execution.
Optimize resource utilization: Multi-threading can reduce the waste of computing power and memory through reasonable scheduling, improve resource utilization, thereby improving system operating efficiency.
It should be pointed out that multi-threading also has some shortcomings and challenges. For example, race conditions may occur between threads, causing problems such as deadlock and starvation, which need to be carefully considered when designing and implementing drivers.
