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 to obtain the Linux kernel source codeHow to obtain the Linux kernel source code To download the Linux kernel, you must go to the official website. The website provides two types of file downloads: one is the complete

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

method. In fact, our Linux Kernel provides the scalability feature during runtime, this means that when the system is started and running, we can add or remove some features to the kernel. The code we add to the kernel during runtime becomes a Dynamically Loaded kernel modu

If the android: debuggable value is not set, the default android: debuggable = "false" is used. Therefore, mos

Before we introduced how to use the Kernel method to generalize linear SVM so that it can deal with non-linear situations, the method used here is through a nonlinear mapping . () The original data is mapped so that the original nonlinear problem becomes a linear problem in the space after mapping. Then we use the kernel function to simplify the calculation, so that the method in practice becomes feasib

for accessing hardware.Hardware compatibility is one of the core design goals, and almost all of the hardware, as long as it is not customized for other operating systems, can be supported by Linux.Related to hardware compatibility is portability, which is the ability to run Linux on different hardware platforms. This breadth of platform support has been successful, in part because the

Linux Kernel Design and Implementation of Reading Notes, Linux Kernel Chapter 3 Process Management 1. fork system calls are returned twice from the kernel: one is returned to the sub-process and one is returned to the parent process. the task_struct structure is allocated by

space is stored in the kernel code and data, and the process of user space is stored in the user program code and data. Both the kernel space and the user space are in virtual space.(2) Linux uses a level two protection mechanism: level 0 for the kernel, and 3 for user programs.Why not allocate all the address space t

small space, and then the address of the space as a map address. This means that a temporary mapping will cause the previous mappings to be overwritten. Temporary mappings can be implemented by Kmap_atomic ().can refer to: Linux high-end memory mapping and so onProblems:1. Does the user space (process) have a high-end memory concept?User processes do not have high-end memory concepts. Only high-end memory exists in
