First, How does the Linux kernel organize the files in each directory tree and compile them? and build a kernel with specific features as needed? in theLinuxin the kernel, there are two types of files:Makefile,Kconfig. The two files are distributed in the various levels of the kernel directory (each level corresp

1 kernel Object definition:1.1: Each Kernel object is just a block of memory allocated by the kernel and can only be accessed by that kernel.1.2: the memory block is a data structure whose members are responsible for maintaining various information about the object.Some data members (such as security descriptors, usage

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/

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

I think the learning method mentioned by the author is worth looking. The following is what I wrote: Almost every beginner of the operating system kernel will feel difficult to get started. This is because the kernel involves a wide range of knowledge and requires learners to master a large amount of knowledge, including program compilation, links, loading details, operating system theory, and computer syst
