linux kernel containers

Sleep a good sleep, very late, for a long time not so comfortable, today's task is not heavy, so the pressure is not big, oh, the weather is really cold, but the laboratory has air conditioning, I still like to stay here, there is a different feeling, after writing so many days, I do not understand the page gradually enlightened, And also made some friends, really very happy ah. Today will introduce you to add code to the kernel, take a look at it ~Fi

The Linux kernel module provides a simple introduction to the overall architecture of the Linux kernel, which is already large and includes components or many more. How do we include the required parts in the kernel?One way is to compile all the required functions into the

X86 platform: The Linux system compiles the configuration kernel and starts the kernel This article turns from: http://blog.chinaunix.net/uid-25811099-id-1704590.html PC System: Windows XP Virtual machine: VMware 6.5.1 build-126130 Virtual machine system: Linux system (provided on version:2.6.25-14.fc9.i686 friendly

For C in Linux, the GCC compiler is used for compiling, and the source code of the kernel is also dependent on the corresponding GCC version. Because a large number of double-stranded tables are required in the kernel, the data structure of the double-stranded table is abstracted to become the list_head struct. For this problem, the

Transferred from: http://www.linuxidc.com/Linux/2013-12/93637.htmWhen migrating Linux to a new architecture, a number of issues that developers encounter are related to incorrect data types. Sticking with strict data types and compiling with-wall-wstrict-prototypes can avoid most bugs. -wall Show all warnings -wstrict-prototypes Rigorous detection of prototypes, if n

Linux Kernel Learning notes collation.UnixUnix has a history of 40, but computer scientists still think it is the largest and best system in the existing operating system, it has become a legendary existence, the test of time is still a reputation.In 1973, after the UNIX system was rewritten in C, a large number of Unix-derived versions began to emerge, and many companies migrated UNIX to new models, and de

. Signal Processing(1) unsigned long signal;The signal received by the process. Each represents a signal of 32 types. The specified location is valid.(2) unsigned long blocked;The bitmask that the process can accept. The position indicates blocking, And the reset indicates not blocking.(3) struct signal_struct * SIG;Because both signal and blocked are 32-bit variables, Linux can only accept up to 32 signals. For each signal, each process can select a

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 leve

1. The Code in the underlying Linux kernel is mostly completed in assembly language. assembly code exists in two forms. One is a pure assembly code file suffixed with. S. Of course, the precompilation option is also added to such assembly code, rather than just assembly. The other is to embed the assembly language in the C language. Although there are no provisions on Assembly fragments in ansi c languag

Myinterrupt.cThe My_time_handler () implementation is called per thousand and the Dispatch flag (my_need_sched) is not 1 o'clock, printing ">>>my_timer_handler hereThe above code is the process scheduling function fault-toler
