Hi , 

     I'm using intel's  Multi Channel DMA for PCI Express . In the user guide it says we have a global MSI-X enable but i'm not able to find it. How to program this global bit as 1. 

 

Thanks and REgards

HI,


I believe the global bit is referring to bit[9:8] in table 13 Q_CTRL (Offset 8’h0) (page 19)


Thanks.
