Specific questions Reference Solutions Solution Ideas Deep solution 1. Specific questions:After porting the kernel of 3.6.6, download the startup card to die, specifically the serial printing information stuck in "uncompressing Linux ... done, booting the kernel."2. Reference Solution:According to the online statement to ensure that the following conditions: 2.1 Core clock frequenc

https://www.ibm.com/developerworks/cn/linux/l-kerns-usrs/#ibm-pcon first, the introduction In general, the kernel and application have different address spaces on a multitasking system that uses virtual memory technology, so data exchange between the kernel and applications and between applications and applications requires specialized mechanisms for implementation, and it is well known that Inter-process

This "Linux kernel cultivation of the road" in excellence, when, China-pub has also been on sale, although serious literature, but in order to ensure fluency, most of the text I also are the words of the burning sentence, repeated

1. Comparison of several kernel debugging tools KDB: Debugging can only be performed at the compilation code level;The advantage is that two machines are not required for debugging. GDB: it lacks some essential functions when debugging A module. It can be used to view the running status of the kernel, including disassembly of kernel functions. Kgdb: it is conven

The mutex Kernel Object ensures that a thread exclusively accesses resources. The behavior characteristics of mutex kernel objects are similar to those of key code segments, but they are kernel objects, and key code segments are user mode objects, as a result, the mutually exclusive kernel objects run at a lower speed

Features of Linux kernel development Compared with applications in a user spaceProgramThere are many differences in development and kernel development. The most important differences include: 1) The C library cannot be accessed during kernel programming. 2) gnu c must be used for Kernel programming. 3) There is

Kernel-level thread and user-level thread, kernel-level thread user When I wrote this blog these two days, I reviewed the operating system materials and encountered a problem that I did not understand before, that is, about kernel-level threads and user-level threads. After reading some documents, I will share my personal profile. Threads have been implemented in

1, 1, the kernel and the release version of the difference1, what is the operating system(1) The operating system is the management of computer hardware, to the application to provide a running environment, such as memory, serial, keyboard, mouse, and so on hardware, is managed by the operating system, the application is to run on the operating system. The operating system is essentially a program that is compiled and connected by many source files, s

One, why to learn the kernel? Some people have to learn the kernel, while others can not learn it. If you want to engage in system development or drive development in the future, you should learn the kernel. Just contact the kernel, mainly learn the interface function of the kern
