The idea behind interrupts is that the computer can be interrupted during processing to handle a high-priority task, such as an I/O device that needs servicing. The processor stops its current task, executes the interrupt handling code, and then returns to the original task. The 8086 ...

6.4.4 Posted Interrupts ELI的缺点是1)基于对中断目标的假设,影响host处理中断的性能;2)使hypervisor的设计变得更复杂;因此ELI未被广泛使用,反而硬件支持从2016年开始出现(intel VT-d posted interrupts, AMD advanced virtual interrupt controller). Posted interruptes分为CPU posted和IOMMU posted两类,前者的使用场...
it was obvious that I had to slant my pick in one direction on the downstroke, and in another direction on the upstroke, to avoid the pick getting caught in the strings.
3Software interrupts These interrupts are initiated by software to perform various operations such as writing to a disk file, reading from theserial portetc. These built-in interrupt handling routines are a part of the computer'sBIOS– Basic Input/Output Services. ...
