一个操作系统的设计与实现——第13章 任务(四):任务回收

在前面的两章中,我们的操作系统均不支持任务回收,所以任务不能退出。本章将要实现的是任务回收功能。 13.1 任务回收的原理 如果一个任务位于任务队列中,其就会被运行。所以,如果一个任务的运行已经结束,它就应该从任务队列中删除。 仅仅将任务从任务队列中删除是不够的,这是因为任务还持有一些内存没有释放, ......

一个操作系统的设计与实现——第11章 任务(二):0特权级任务

上一章中,我们的操作系统已经支持内核共享,这为任务的加载和运行做好了准备。 本章将要实现的是0特权级任务的加载与任务切换。 11.1 任务切换的原理 11.1.1 协同式与抢占式任务切换 如果CPU上只运行着Kernel.c的main函数,那么情况非常简单,只需要不断执行下一条指令即可。然而,如果现 ......

一个操作系统的设计与实现——第12章 任务(三):3特权级任务

特权级是保护模式的核心概念之一,但我们的操作系统一直没有引入这个概念。这是因为,特权级只有在3特权级任务存在时才有意义。本章将要实现的是3特权级任务的加载与任务切换。 12.1 特权级 12.1.1 特权级的功能 特权级(Privilege Level),是保护模式中用于限制任务权限的机制。特权级有 ......

一个操作系统的设计与实现——第10章 任务(一):共享内核

一直以来,我们的操作系统在启动后,运行的都是Kernel.c中的main函数。只运行这一个函数是不够的,操作系统应当有能力加载并运行其他程序。 从本章开始,将使用四章的篇幅讨论操作系统如何加载并运行任务。这里的任务(Task)与进程(Process)是同义词,在操作系统领域中,任务这个词更为常用,请 ......

To_Heart—总结——连通块 dp(抑或 连续块 dp)

简介 有一类问题,他们需要计算满足在序列上插入给定顺序的元素,其贡献/限制只与两旁的元素有关,但元素插入的位置是不一定的,所以会有代价的最值和方案数的统计。而对于这类问题,我们其实可以不关心每一次插入的具体位置在哪里,而只关注他的相对位置(比如在某个数左边、在某个数左边且与其相邻之类的),从而将状态 ......
