lending kernel

The Linux 2.4 kernel provides a better description than the kernel-Linux general technology-Linux programming and kernel information. For more information, see the following. 1. Module Subsystem, Unified Device Model, and PnP support Module Subsystem have undergone major changes. 2. Improved Stability To completely prevent the

Linux Architecture:Knowledge: Linux architecture is divided into user space and kernel spaceWhat is the reason for dividing into user space and kernel space? Protect the operating system so that the application and the kernel have different permissions. Create different levels for different codes ...Kernel space and us

Press the power supply, click it, start the computer, and then the BIOS screen will pop up. After a while, the GRUB interface will pop up, and a line after line of characters will pop up on the black screen, from time to time there are OK words. oh, don't worry. Enter your username and password ,.... The system is successfully started. So what happened in this process and what are worth learning? This article describes the relationship between the boot loader,

Recently, FC 10 (fedora10) was installed on the machine (x86_64). to install the virtual machine, first install VM 6.5. It was found that it was very difficult to install VM 6.5 in 64-Bit mode for three days, give up. Some people say that the 64-bit VM under FC 10 cannot be installed. As a result, I switched to Sun's Virtual Machine Software virtualbox. On the official virtualbox website, I found the rpm version of fedora9/10 corresponding to x86_64. I read a lot of posts on how to install it. A

My kernel upgrade is from 2.6.32.5 to 2.6.38.2. The beginning of these sections is followed by the following article: http://blog.csdn.net/ctbinzi/article/details/6006931 Install the required software first, and download the latest kernel:#apt-get Install kernel-package libncurses5-dev wget bzip2 make patch#cd/USR/SRC#wget http://www.kernel.org/pub/linux/

(This method is limited to the CentOS faction's yum/rpm.) Supplement: limited to 64Bit. CentOS7 32-bit, I tried to use CentOS6 32-bit kernel to upgrade, can be upgraded to use the restart can be used, half an hour after the deletion of the system no longer try to use, so do not know what will bring bad experience. ） The way to upgrade the kernel of CentOS and Debian has been mentioned in the previous logs.

First, let's talk about how this problem came about. (When analyzing a technology, we should first consider what problems it wants to solve, or when learning new knowledge, what is the purpose of this knowledge ). When compiling the kernel, I found a file named vmlinux. LDS. s under the arch/ARM/kernel directory. At first glance, do you want to compile a file? It seems that it is not. So what does it do?

instructions in the critical section are executed continuously, and may be executed in the critical section half way, Because the scheduler is preempted or interrupted, the CPU does not continue to execute within the critical zone, which means the execution is interrupted.But that still guarantees the avoidance of competitive conditions, the reason is that if a process outside of the interrupted process is scheduled, the process will have to access the critical section, the lock or semaphore, a

Linus Torvalds has upgraded the Linux kernel to Kernel 4.0.2, new kernel patches and newer Bluetooth, USB, SCSI, ACPI drivers, increased NFS and EXT4, and improved ARM64 and PowerPC architectures.In addition to updated drivers, enhanced support for new devices and file systems also brings the long-awaited life patching feature, allowing users to update the

Kernel and operating systemBecause of the flaws in the design of some commercial operating systems and the increasing complexity of the system, the concept of "operating system" has become ambiguous for many people. Before we further discuss the topic of the Linux kernel, we first distinguish between the concepts of "kernel" and "operating system". opera
