7.1.3. Message Signaled Interrupts (MSI and MSI-X) 信息信号中断 这允许设备驱动开启MSI。MSI允许一个设备用非装订内存写入方式在自己的PCI总线中产生一个中断,而不是常规的IRQ针脚中断。 在内核启动时,用 'pci=nomsi'选项可以禁用PCI MSI中断。这将在整个系统禁用MSI。

Then add MessageSignaledInterruptProperties key and dword value MSISupported = 1. Now both Intel, NVIDIA and even AMD work together in Windows and seems finall stable: It is very important that all GPUs have negative IRQ in device manager. Also beware - updating NVIDIA driver will disable MSI...
