Basic concepts 1. A linked list is a commonly used data structure that passes through pointers Connect a series of data nodes into a single data chain. Phase For the array, the linked list has a better dynamic nature, and establishes Linked list without prior knowledge of the total amount of data, you can randomly Allocate space that can be efficiently in any bit of the list Inserts or deletes data in real time. 2. The cost of the linked list is mainly is the order of access and the loss of

Kernel Address Space Distribution Direct ing zone: The maximum m range starting from 3G in a linear space. It is a direct memory ing zone. The linear address and physical address in this region have a linear conversion relationship: linear address = 3G + physical address. Dynamic Memory ing area: This area is allocated by the kernel function vmalloc. It features linear space continuity, but the correspond

Adding a driver to the android kernel is actually adding a driver to the Linux kernel. It mainly adds vertex information to two files, one is the kconfig file and the other is the MAKEFILE file. For example, if the driver you added is placed in the xxx directory under the DRIVERS directory, the kconfig and makefile files under the directory will be repaired. Spec

structure used by the kernel timer (different kernel timing events are connected in the form of a doubly linked list):struct Timer_list {struct list_head entry;//list header unsigned long expires;//delay time struct tvec_base *base;void (*function) (uns igned long); The target function is called unsigned Long data when the timing time arrives; The data that the target function carries ...}; Init_t

Loader to do two things, let's start with the first item, load the kernel into memory:1. Load the kernel into memory.2. Jump into protected mode.When you first compile a no-kernel:NASM Boot.asm-o Boot.binNASM Loader.asm-o Loader.binDD if=boot.bin of=a.img bs=512 count=1 conv=notruncsudo mount-o loop a.img/mnt/hgfs/sudo cp loader.bin/mnt/hgfs/-Vsudo umount/mnt/hgfs/The results of the operation are as follows

Introduction to the Kernel Kernel, is the core of an operating system. It is responsible for managing the system's process, memory, device driver, file and network system, which determines the performance and stability of the system.linux is an important feature of the openness of its source code, all the kernel sour

understand the C implementation of data structures such as linked lists and scattered lists, and you can use the gcc compiler. Of course, if you are already proficient in the C language, it is obviously a huge advantage. 3. Knowledge about CPU. This part can be supplemented in the kernel learning process. However, you need to read a detailed book, for example, situation analysis, which will be mentioned l

After the BIOS triggers a 0x19 interrupt, the first sector (512B) of the disk is loaded into memory. The computer really starts running programs on disk. And this 512B program is BOOTSECT.S, at this time the processor is still in real mode memory addressing the maximum range is 1M (0X0000-0XFFFF), next we look at Bootsect.s in the first batch of code to do?The code above declares the assignment of a series of variables for memory planningThis command means to jump to the new copy of Bootsect whe

Phenomenon:CentOS7 boot screen displays multiple kernel optionsReason:Under normal circumstances, there are two startup items, one is "Normal startup" and the other is "Rescue mode Startup" (rescue).If there are more than 2 startup items, the old kernel of the current system is not removed. The reason is that the old kernel is not automatically deleted after the

One: Linux kernel: The operating system is a low-level support software used to deal with hardware and provide a limited set of services for user programs. A computer system is a symbiotic body of hardware and software that is interdependent and indivisible. Computer hardware that contains peripherals, processors, memory, hard disks, and other electronic devices that make up the computer's engine. But with
