To say clear Systemd, you have to start with the Linux operating system started speaking. The startup of the Linux operating system starts with the BIOS, then the boot Loader loads into the kernel and initializes the kernel. The final step in kernel initialization is to start the init process. This process is the first process of the system, PID 1, also known as

The USB boot made by moblin mic2 has two methods: liveos, direct boot, and traditional installation of Linux OS on the device. I want to install moblin2 on mid (menlow) and need to rebuild the kernel. You can use moblin-chroot to compile the kernel development environment or KVM. Get the source code for the kernel from the moblin repo site, such as the wget htt

As mentioned in the previous article, the latest Android source code downloaded from the source code tree does not contain kernel code, that is, the android source code project does not contain Linux kernel code by default, instead, use the pre-compiled kernel, that is, the prebuilt/Android-arm/kernel-qemu file. So how

The Linux kernel of Android is stored in the kernel subdirectory. By comparing it with the standard Linux 2.6.25 kernel, we can find that it mainly adds the following content: 1. Add the gold-fish platform based on the ARM architecture. The directories added are as follows: Kernel/ARCH/ARM/Mach-goldfish

In factCodeI have been analyzing it for a long time. I have long wanted to write something for myself. From today on, I will continue my blog! I have been dealing with Linux over the past few years, and I think I really fall in love with Linux. So write something about Linux! Linux has many things. As far as the kernel is concerned, it is impossible for a single person to understand all the mechanisms and details. But fortunately, the source code

Binary Search and its implementation in the database kernel | go deep into the MySQL Kernel Binary Search and its implementation in the database Kernel Posted on April 1, 2013 By Hedengcheng Problem background During this year's intern recruitment examination, I got a binary search question. The question is as follows: Give

: Wait (Wait) and Release (Release ). When a thread calls the Wait (Wait) operation, it either reduces the semaphore by one or waits until the semaphore is greater than one or times out. Release (Release) is actually an addition operation on the semaphore, corresponding to the vehicle leaving the parking lot. This operation is called "Release" because the addition operation actually releases the resources protected by the semaphore. Before installing Oracle, you usually need to set the

Label:This paper mainly analyzes several kernel functions related to debugging in the kernel. The first is the Ntcreatedebugobject function, which is used to create a kernel debug object, and the parser shows that it is just a layer of obcreateobject encapsulation and initializes some struct members. I'll write some notes about the management of the Window object
