Linux Kernel development-process scheduling and Linux kernel Process Scheduling This section briefly introduces the knowledge about process scheduling in kernel development. What is process scheduling? Process Scheduling is to select the most appropriate process execution process from a ready process. Process Scheduling Policy Real-time Class Scheduling Polic

It is linked to the kernel at run tim

How can we compile the kernel module before? Describes how to compile modules. Here, we will continue to introduce how to compile kernel modules in the 2.6 kernel. The method for compiling the kernel module is slightly different from that for compiling general applications. makefile exists in the directory of the

Because the kernel does not differentiate between processes and threads, kernel threads (kernel thread) are also called kernel processes (kernel process). Note that threads in normal processes cannot be understood as processes. The difference between a
