BTC挖矿让英伟达飞起来了，当然也与英伟达在并行计算机领域的强大技术能力有关。这次国外黑客把英伟达的代码公开给大家。让中国人有机会一睹英伟达的显卡驱动的芳容。
此贴就重点来研究一下英伟达windows驱动代码。显卡驱动对许多人来说还是比较神密的。首先做PC显卡的就那三家：nvidia,intel,amd。这就造成了windows显卡驱动几乎没什么人接触，研究。即使是做游戏辅助的人也很少观注显卡驱动本身。
本帖就以号称显卡技术巅峰的nvidia驱动为研究对象进行剖析，以此来抛砖引玉。
源代码下载链接就不提供了，大家可以自行谷歌，非常好找。
剖析的方式包括分析源代码，ida逆向binary驱动，windbg调试硬件，相互佐证代码的真实性。
如下图所示，为了安全起见，建议放在vmware虚拟机进行解压，分析，原因是黑客可能在某些脚本里植入有病毒（当然不去执行里面的代码是没问题的）


第1步，先把代码载入source insight里

第2步，找出驱动的入口点DriverEntry



很明显代码是用C++编写，也用到了很多的类及模板

初始化部分代码很长，分段分析













现在来看一下最重要的函数DxgkInitialize的具体流程




流程结束

现在来看一下nvdia真实显卡驱动的二进制分析
配置好调试环境，用windbg连上

定位驱动

根据路径找到显卡驱动的位置，这个文件有足足36M，太庞大了，看来英伟达为了做好驱动也是下足了工夫

载入IDA Pro开始分析






以上分析可知这代码保真，没问题。

这代码的版权部分写着2022年，还是新鲜出炉的。真是个巨大的宝库。
现在知道了代码的套路，我们用windbg给显卡的中断设一个断点，启动渲染看一下效果



看一下英伟达显卡的PCIe配置空间
1.先确定总线地址（总线号.设备号.功能号）

windbg执行如下命令





英伟达真是强，把微软干的事，他自己干了一遍。

综上：

1.代码是真实无误的
2.英伟达对驱动有着很高的追求（代码里有很多微软的影子，很明显有微软帮忙）
3.代码对现有中国windows GPU驱动开发有着巨大的研究和学习价值，值得业内人士深挖
4.驱动代码是研究英伟达显卡最好的的资料
5.时机成熟可自行编译，调试
以上分析是粗略分析，只是为了抛砖引玉，希望有更多的人来研究这份代码。
里面还有海量的信息供大家挖掘。相信可以找到很多有趣的信息。
