The operating system kernel may be a micro kernel or a single kernel (which is sometimes called a macro kernel macrokernel ). These terms are defined as follows in a similar encapsulation: Single Kernel: Also knownMacro Kernel.

How is Linux composed?A: Linux is made up of user space and kernel spaceWhy divide user space and kernel space?A: For CPU architectures, each processor can have multiple modes, and Linux is a partition that takes into account the system'sSecurity, such as X86 can have 4 mode

During this time, I read "Linux kernel source code Scenario Analysis" and wrote some insights. Reading the kernel source code is very interesting. It is like a line that concatenates basic computer courses such as operating systems, compilation principles, C language, data structures and algorithms, and computer architecture. I think the

Chapter One: Introduction to the Kernel The scope of the processor's activity at any given point in time: A, run in the kernel space, in the process context, on behalf of a specific process execution; b, running in kernel space, in the interrupt context, regardless of any process, handling a particular interrupt; C, run in user space, execute user process. When a

Compiling the Linux kernel is the basic function of kernel development, and if we add kernel functionality by directly modifying the Linux kernel code, the modified kernel code must be

)Add I (7->8)----Increase I (7->8)Write back I (8)----Write back I (8)As described above, concurrent access to shared resources, the I value may appear as 8, resulting in unexpected functionality.Several methods and interfaces are available in the Linux kernel to address the above problems.1. Atomic AccessThat is, atomic execution obtains I, adds I, and writes back I 3 instructions. Examples of related inte
