MSI-X Register Descriptions
These registers are used to configure the MSI-X mechanism. The address and upper
address registers set the address for each of the vectors. The message register sets the
data sent to the relevant address. The vector control registers are used to enable
specific vectors.
The Pending Bit Array register indicates which vectors have pending interrupts.
The structure is listed in
