The execution of the Linux kernel does not have a fixed number of threads, but is dynamically scheduled and executed according to system requirements and hardware resources, because the Linux kernel uses a scheduler to manage processes and switches between different processes through context switching. When a process is running, some kernel threads may be created and managed, but they are not directly involved in the execution of the kernel.

How many threads does the Linux kernel have when executing?

The operating system of this tutorial: Linux5.18.14 system, Dell G3 computer.

When the Linux kernel is executed, it is not organized in threads. Instead, the Linux kernel uses a scheduler to manage processes and switches between different processes through context switches. When a process is running, some kernel threads may be created and managed, but they do not directly participate in the execution of the kernel.

Kernel execution can be performed simultaneously by multiple processor cores, with each core executing kernel code independently. Each processor core has its own registers and execution context to execute instructions within the core. This means that on systems with multiple cores, the execution of the cores can occur in parallel to improve system performance and responsiveness.

In short, the execution of the Linux kernel does not have a fixed number of threads, but is dynamically scheduled and executed based on system requirements and hardware resources.
