不过,这个区别在一些嵌入式系统(可能不具备内核态)或解释性系统中(比如基于 Java 的系统)是模糊的。 同样,在一些系统中,一些程序虽然运行在用户态,却会辅助操作系统的运行,或者执行一些需要特权的功能。比如,有的程序允许用户修改密码,这并不是操作系统的一部分,也不会以内核态运行,但是它们会涉及一些敏感功能,因此...
InterrupHandler 参考ARM System Developer’s Guide Designing and Optimizing System Software 非屏蔽中断:保留用于诸如不可恢复的内存错误等事件。 可屏蔽中断:在执行不得中断的关键指令序列之前,可由CPU关闭。 中断向量:包含专门的中断处理程序的内存地址。目的是,单个中断处理不在需要搜索所有可能中断源。设备多余中断...
