Okay, then I'm missing something. I've seen hardware where enabling MSI is something device-specific (a value in a register, typically), meaning _something_ MD, presumably the driver, has to be involved if MSI is to be used. And how can a driver do this without knowing whether it's supported? /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mo...@rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
