MSI-X Message Control (MXC) – Offset d2
Bit Range | Default | Access | Field Name and Description |
---|---|---|---|
15 | 0h | RW | MSI-X Enable (MXE) If set to '1' and the MSI Enable bit in the MSI Message Control register is cleared to '0', the function is permitted to use MSI-X to request service and is prohibited from using its INTx# pin (if implemented). If cleared to '0', the function is prohibited from using MSI-X to request service. |
14 | 0h | RW | Function Mask (FM) If set to '1', all of the vectors associated with the function are masked, regardless of their per vector Mask bit states. If cleared to '0', each vector's Mask bit determines whether the vector is masked or not. Setting or clearing the MSI-X Function Mask bit has no effect on the state of the per vector Mask bits. |

10:0 | 0h | RO | Table Size (TS) This value indicates the size of the MSI-X Table as the value n, which is encoded as n - 1. For example, a returned value of 3h corresponds to a table size of 4. |
