Concept APIC (advanced programmable interrupt control) advanced programmable interrupt controller. It consists of two parts: Io APIC: located in the south bridge, used to handle various interruptions caused by devices on the bridge. I

The working principle of the interrupt controller between different CPU systems is quite different, this article is the sister of "the analysis of circuit breaker in Linux MIPS64R2 PCI", mainly analyzes the principle, interrupt configuration and processing process of broadwell-de x86_64 APIC. And try to answer the following questions: Why is the x86 used in the IO-APIC/LAPIC framework, and what is

Apic-v, APIC virtualization, is an optimization of the Intel CPU for virtual interrupts and APIC virtualization, and using APIC-V can substantially reduce the number of VM exit results due to APIC access, tracking virtual APIC sta

In Linux, ACPI and APIC-general Linux technology-Linux technology and application information are described below. A friend of mine has a problem with the startup of his notebook system. ubuntu is used. It is said that the startup speed is getting slower. Today, it is completely unable to get in, and the progress bar stops halfway through. I looked at it and press alt + f1 after the progress bar is stopped. The following message is displayed: Checkin

OC-class definition and oc-DefinitionWe have already introduced a program HelloWorld: Keep in OC. The biggest difference between OC and C is that it has the Object-Oriented function. When it comes to object-oriented, we have to talk about the class concept. If we have learned Java, so there is no stranger to the concepts of classes and objects, Because Java is a very pure object-oriented design language. I will not elaborate on the concepts of classe

To write a good C language, a beautiful macro definition is very important. Macro definitions can help us prevent errors, improve code portability and readability, and more.In the software development process, there are often common or common functions or code snippets that can be written as functions or encapsulated as macro definitions. So is the function good or the macro definition good? This requires u

Many people even think that the causal association ability of talent is one of the first conditions for human beings to become a "Everlasting thing. In philosophy, there a

　　They have a common advantage is "change the whole, to avoid the input error" What are the two different? Some.The main difference is that the macro definition is done prior to compilation, and the const is processed during the compilation phaseMacros define constants that do not occupy memory cells and are defined by const occupy memory unitsA macro definition has the same effect as a const constant-----t

In the previous article, we tried to use list template to help us quickly create a schema in our list definition. XML file, you may find that we cannot copy the corresponding definition content in the list template.The corresponding content in list definition is different in description, which is normal because list template and list

Python array definition method, python array Definition This article describes how to define Python arrays. We will share this with you for your reference. The details are as follows: Python does not have an array data structure, but the list is similar to an array, for example: a=[0,1,2] In this case, a [0] = 0, a [1] = 1, a [[2] = 2, but a problem occurs, that is, what if array a is to be defined as 0 to

C ++ macro definition commands and macro definition commandsCommands starting with # In a program are pre-compiled commands. There are three types of pre-compiled commands: macro definition commands, file inclusion commands, and Conditional compilation commands. Today we will talk about macro definition: macro
