中文摘要: 介绍了设计并实现的基于显卡直接分配的虚拟机图形加速系统Gracias，它的思想是把显卡直接分配给某一台完全虚拟化的虚拟机使用。这样一来，虚拟机中显卡的设备驱动程序对于显卡的使用和访问操作就不会被虚拟机监控器所拦截，也不用通过软件模拟的方式来处理这些访问请求，而是直接交给真实的硬件去完成。这使得对图形处理要求很高的程序在虚拟机中可以获得比普通虚拟化方法高很多的性能提升。
Abstract:This paper presents Gracias (Graphic Card Direct Assignment), which directly assign a graphics card to a certain virtual machine. Thus, access request from device driver of the graphic card in virtual machine will not cause any traps into the virtual machine monitor and the request will be handled directly by the hardware instead of software emulation. This makes the programs that have high demand on graphic processing give much better performance than with ordinary virtualization approaches.
