前言前面我们学习了 8259A，但 8259A 只适合单 CPU 的情况，为了充分挖掘 SMP 体系结构的并行性，能够把中断传递给系统中的每个 CPU 至关重要。基于此理由，Intel 引入了一种名为 I/O 高级可编程控制器的新组件，来替代老式的 8259A 可编程中断控制器。下面一起来学习一下 APIC。
0 APIC 概述Intel 从 Pentium 处理器开始引入了 APIC（Advanced Programmable Interrupt Controller）机制，直译为高级可编程中断控制器。引入 APIC 机制是为了适应 multiple processor（MP，多处理器）环境。
APIC 经历了 4 个版本
最初的 APIC 属于外部设备，以外部的 82489DX 芯片形式存在。在 P6 家族和 Pentium 处理器后，以 APIC on Chip 形式存在，引入了处理器内部的 local APIC 架构，和 82489DX 外部 APIC 相比较功能得到了扩展和增强。

从本文开始我们就正式开启了 Linux 内核内存管理子系统源码解析系列，笔者还是会秉承之前系列文章的风格，采用一步一图的方式先是详细介绍相关原理，在保证大家清晰理解原理的基础上，我们再来一步一步的解析相关内核源码的实现。有了源码的辅证，这样大家看得也安心，理解起来也放心，最起码可以证明笔者没有胡编乱造骗大家，哈哈~~
内存管理子系统可谓是 Linux 内核众多子系统中最为复杂最为庞大的一个，其中包含了众多繁杂的概念和原理，通过内存管理这条主线我们把可以把操作系统的众多核心系统给拎出来，比如：进程管理子系统，网络子系统，文件子系统等。
由于内存管理子系统过于复杂庞大，其中涉及到的众多繁杂的概念又是一环套一环，层层递进。如何把这些繁杂的概念具有层次感地，并且清晰地，给大家梳理呈现出来真是一件比较有难度的事情，因此关于这个问题，笔者在动笔写这个内存管理源码解析系列之前也是思考了很久。
万事开头难，那么到底什么内容适合作为这个系列的开篇呢 ？笔者还是觉得从大家日常开发工作中接触最多最为熟悉的部分开始比较好，比如：在我们日常开发中创建的类，调用的函数，在 ...</div></div></div><div class="recent-post-item" onclick="pjax.loadUrl('/2024/07/31/sdn/dpdk/')"><div class="recent-post-info no-cover"><div class="recent-post-info-top"><div class="recent-post-info-top-tips"><a class="unvisited-post" href="/2024/07/31/sdn/dpdk/" title="无题">未读</a></div><a class="article-title" href="/2024/07/31/sdn/dpdk/" title="无题">无题</a></div><div class="article-meta-wrap"><span class="post-meta-date"><i class="anzhiyufont anzhiyu-icon-calendar-days" style="font-size: 15px; display:none"></i><span class="article-meta-label">发表于</span><time datetime="2024-07-31T11:36:18.019Z" title="发表于 2024-07-31 19:36:18">2024-07-31</time></span></div><div class="content">基本前面把环境基本搭好，今天开始编译 DPDK。首先是下载 DPDK 的源码，地址是：https://core.dpdk.org/download/也可以从官网 https://www.dpdk.org / 跳过来。然后就可以看到排下载的 DPDK 的版本：

一：轮询算法 (Round-Robin)
轮询算法是最简单的一种负载均衡算法。它的原理是把来自用户的请求轮流分配给内部的服务器：从服务器 1 开始，直到服务器 N，然后重新开始循环。
算法的优点是其简洁性，它无需记录当前所有连接的状态，所以它是一种无状态调度。
假设有 N 台服务器：S = {S1, S2, …, Sn}，一个指示变量 i 表示上一次选择的服务器 ID。变量 i 被初始化为 N-1。该算法的伪代码如下：
12345678j = i;do{ j = (j + 1) mod n; i = j; return Si;} while (j != i);return NULL;
轮询算法假设所有服务器的处理性能都相同，不关心每台服务器的当前连接数和响应速度。当请求服务间隔时间变化比较大时，轮询算法容易导致服务器间的负载不平衡。所以此种均衡算法适合于服务器组中的所有服务器都有相同的软硬件配置并且 ...</div></div></div><div class="recent-post-item" onclick="pjax.loadUrl('/2023/11/02/sdn/Using%20ONOS%20as%20a%20robust%20SDN%20controller%20with%20Mininet/')"><div class="recent-post-info no-cover"><div class="recent-post-info-top"><div class="recent-post-info-top-tips"><a class="unvisited-post" href="/2023/11/02/sdn/Using%20ONOS%20as%20a%20robust%20SDN%20controller%20with%20Mininet/" title="using onos as a robust sdn controller with mininet">未读</a></div><a class="article-title" href="/2023/11/02/sdn/Using%20ONOS%20as%20a%20robust%20SDN%20controller%20with%20Mininet/" title="using onos as a robust sdn controller with mininet">using onos as a robust sdn controller with mininet</a></div><div class="article-meta-wrap"><span class="post-meta-date"><i class="anzhiyufont anzhiyu-icon-calendar-days" style="font-size: 15px; display:none"></i><span class="article-meta-label">发表于</span><time datetime="2023-11-02T03:12:32.000Z" title="发表于 2023-11-02 11:12:32">2023-11-02</time></span><span class="article-meta tags"><a class="article-meta__tags" href="/tags/sdn/" event.cancelbubble onclick="window.event.cancelBubble=true;"><span> <i class="anzhiyufont anzhiyu-icon-hashtag"></i>sdn</span></a><a class="article-meta__tags" href="/tags/network/" event.cancelbubble onclick="window.event.cancelBubble=true;"><span> <i class="anzhiyufont anzhiyu-icon-hashtag"></i>network</span></a><a class="article-meta__tags" href="/tags/ONOS/" event.cancelbubble onclick="window.event.cancelBubble=true;"><span> <i class="anzhiyufont anzhiyu-icon-hashtag"></i>ONOS</span></a></span></div><div class="content">1 环境准备1.1 安装mininet这里通过源码方式进行mininet的安装

模块是相关 Go 包的集合。modules 是源代码交换和版本控制的单元。 go 命令直接支持使用 modules，包括记录和解析对其他模块的依赖性。modules 替换旧的基于 GOPATH 的方法来指定在给定构建中使用哪些源文件。
使用 modules 依赖管理的好处是非常明显的：
自动下载依赖包S
不需要将代码再放入 $GOPATH/src
所有来自第三方的包都会指定版本（使用 dep 是无法指定第三方包的版本的）
对于已经转移的包，可以用 replace 在 go.mod 文件中替换，不需要修改代码
如何使用 Modules
把 golang 升级到 1.11+ (现在已经到 1.19 了)
设置 GO111MODULE
GO111MODULE
GO111MODULE 有三个值：off, on和auto（默认值）。
GO111MODULE=off，go 命令行将不会支持 module 功能，寻找依赖包的方式将会沿用旧版本那种通过 vendor 目录 ...</div></div></div><div class="recent-post-item" onclick="pjax.loadUrl('/2023/10/08/cmake%20starter/')"><div class="recent-post-info no-cover"><div class="recent-post-info-top"><div class="recent-post-info-top-tips"><a class="unvisited-post" href="/2023/10/08/cmake%20starter/" title="cmake starters">未读</a></div><a class="article-title" href="/2023/10/08/cmake%20starter/" title="cmake starters">cmake starters</a></div><div class="article-meta-wrap"><span class="post-meta-date"><i class="anzhiyufont anzhiyu-icon-calendar-days" style="font-size: 15px; display:none"></i><span class="article-meta-label">发表于</span><time datetime="2023-10-08T03:25:56.000Z" title="发表于 2023-10-08 11:25:56">2023-10-08</time></span><span class="article-meta tags"><a class="article-meta__tags" href="/tags/c/" event.cancelbubble onclick="window.event.cancelBubble=true;"><span> <i class="anzhiyufont anzhiyu-icon-hashtag"></i>c</span></a></span></div><div class="content">▌什么是 CMake?
你或许听过好几种 Make 工具，例如 GNU Make ，QT 的 qmake ，微软的 MS nmake，BSD Make（pmake），Makepp，等等。这些 Make 工具遵循着不同的规范和标准，所执行的 Makefile 格式也千差万别。这样就带来了一个严峻的问题：如果软件想跨平台，必须要保证能够在不同平台编译。而如果使用上面的 Make 工具，就得为每一种标准写一次 Makefile ，这将是一件让人抓狂的工作。CMake 就是针对上面问题所设计的工具：它首先允许开发者编写一种平台无关的 CMakeList.txt 文件来定制整个编译流程，然后再根据目标用户的平台进一步生成所需的本地化 Makefile 和工程文件，如 Unix 的 Makefile 或 Windows 的 Visual Studio 工程。从而做到 “Write once, run everywhere”。显然，CMake 是一个比上述几种 make 更高级的编译配置工具。一些使用 CMake 作为项目架构系统的知名开源项目有 VTK、ITK、KDE、OpenCV、OSG 等 [ ...</div></div></div><nav id="pagination"><div class="pagination"><span class="page-number current">1</span><a class="page-number" href="/page/2/#content-inner">2</a><span class="space">…</span><a class="page-number" href="/page/11/#content-inner">11</a><a class="extend next" rel="next" href="/page/2/#content-inner"><div class="pagination_tips_next">下页</div><i style="font-weight: inherit; font-size: 1rem;" class="anzhiyufont anzhiyu-icon-chevron-right fa-fw"></i></a><div class="toPageGroup"><input id="toPageText" oninput="value=value.replace(/[^0-9]/g,'')" maxlength="3" onkeyup="this.value=this.value.replace(/[^u4e00-u9fa5w]/g,'')" aria-label="toPage"><a id="toPageButton" onclick="anzhiyu.toPage()"><i class="anzhiyufont anzhiyu-icon-angles-right" style="font-weight: inherit; font-size: 1rem;"></i></a></div></div></nav></div><div class="aside-content" id="aside-content"><div class="card-widget card-info"><div class="card-content"><div class="author-info-avatar"><img class="avatar-img" src= "data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" onerror="this.onerror=null,this.src="/img/404.jpg"" data-lazy-src="https://bu.dusays.com/2023/04/27/64496e511b09c.jpg" onerror="this.onerror=null;this.src='/img/friend_404.gif'" alt="avatar"/></div><div class="author-info__description"></div></div></div><div class="card-widget anzhiyu-right-widget" id="card-wechat" onclick="null"><div id="flip-wrapper"><div id="flip-content"><div class="face" style="background: url(https://bu.dusays.com/2023/01/13/63c02edf44033.png) center center / 100% no-repeat"></div><div class="back face" style="background: url(https://bu.dusays.com/2023/05/13/645fa415e8694.png) center center / 100% no-repeat"></div></div></div></div><div class="sticky_layout"><div class="card-widget"><div class="card-tags"><div class="item-headline"></div><div class="card-tag-cloud"><a href="/tags/DPDK/" style="font-size: 1.05rem;">DPDK<sup>3</sup></a><a href="/tags/ONOS/" style="font-size: 1.05rem;">ONOS<sup>1</sup></a><a href="/tags/algorithm/" style="font-size: 1.05rem;">algorithm<sup>1</sup></a><a href="/tags/blockchain/" style="font-size: 1.05rem;">blockchain<sup>1</sup></a><a href="/tags/c/" style="font-size: 1.05rem;">c<sup>1</sup></a><a href="/tags/configuration/" style="font-size: 1.05rem;">configuration<sup>1</sup></a><a href="/tags/container/" style="font-size: 1.05rem;">container<sup>25</sup></a><a href="/tags/go/" style="font-size: 1.05rem;">go<sup>14</sup></a><a href="/tags/kidgets/" style="font-size: 1.05rem;">kidgets<sup>3</sup></a><a href="/tags/linux/" style="font-size: 1.05rem;">linux<sup>40</sup></a><a href="/tags/network/" style="font-size: 1.05rem;">network<sup>8</sup></a><a href="/tags/rust/" style="font-size: 1.05rem;">rust<sup>6</sup></a><a href="/tags/sdn/" style="font-size: 1.05rem;">sdn<sup>4</sup></a><a href="/tags/systemtap/" style="font-size: 1.05rem;">systemtap<sup>4</sup></a><a href="/tags/tools/" style="font-size: 1.05rem;">tools<sup>1</sup></a><a href="/tags/tvbox/" style="font-size: 1.05rem;">tvbox<sup>1</sup></a><a href="/tags/%E7%BD%91%E7%BB%9C/" style="font-size: 1.05rem;">网络<sup>1</sup></a></div></div><hr/><div class="card-archives"><div class="item-headline"><i class="anzhiyufont anzhiyu-icon-archive"></i><span>归档</span><a class="card-more-btn" href="/archives/" title="查看更多">
