In this tutorial, we will find out some possible reasons that can cause the sema-init kernel to fire, and then I will give some possible fixes that you can try to get rid of this problem.
Linux Semaphore Implementation
The semaphore mechanism returns scull tool that can used to maintain constant conditions when accessing the scull_dev data structure. But it depends on us whether to use this resource correctly. That Recommendations for the correct use of backup primitives is to specify exactly which online resources to use. are lined up and make sure that anyone accessing those resources is using the correct lock. In our driver example, everything we care about is usually contained in the scull_dev structure, so this is a smart area for us. standard blocking.
Semaphores
Semaphores are a more “savvy” form of synchronization thantwist locks. Instead of wasting CPU time on busy cycles,Semaphore properties can put processes to sleep untilthe resource becomes available. While the best process sleepsThe CPU can take over other tasks and is therefore used optimallyof their time and raise the overall level ofspecific systemmultiprogramming.
A.1.2 Low-level Kernel Initialization
The last action of the bootloader is to transfer all control of the kernel’s input.point, this is start() from threads/start.S. WorkThis preset is used to enable the processor in the legacy 16-bit “real mode”.32-bit “protected mode”, which exploits all current 80x86systems.
