453 Read the MSI routing ID.
454 This is needed by some interrupt controllers to route MSI and MSI-X interrupts.
821 .Pq MSI
824 .Pq MSI-X
830 MSI and MSI-X interrupts are available to PCI devices as one or more
833 A driver must ask the PCI bus to allocate MSI or MSI-X interrupts
838 before it can use MSI or MSI-X
843 resource if MSI or MSI-X interrupts have been allocated,
844 and attempts to allocate MSI or MSI-X interrupts will fail if the
848 A driver is only allowed to use either MSI or MSI-X,
853 function returns the maximum number of MSI messages supported by the
856 If the device does not support MSI,
873 or if the system has a shortage of available MSI messages.
887 Note that MSI only supports message counts that are powers of two;
892 function is used to release any allocated MSI or MSI-X messages back
894 If any MSI or MSI-X
906 function returns the maximum number of MSI-X messages supported by the

918 containing the MSI-X Pending Bit Array (PBA) for device
925 If the device does not support MSI-X,
933 containing the MSI-X vector table for device
940 If the device does not support MSI-X,
957 or if the system has a shortage of available MSI-X messages.
963 For MSI-X messages,
966 resource identifies the index in the MSI-X table of the
968 A resource ID of one maps to the first index of the MSI-X table;
981 Unlike MSI,
984 The BARs containing the MSI-X vector table and PBA must be
999 to determine the pending status of the MSI-X message at table index
1031 The array maps directly to the MSI-X table in that the first entry in
1032 the array specifies the message used for the first entry in the MSI-X
1038 that no message should be assigned to the corresponding MSI-X table entry,
1045 corresponding MSI-X table entry.
1050 each MSI-X table entry with a non-zero vector will have an associated
1062 are not used in the new distribution of messages in the MSI-X table,
1129 The PCI bus driver should allocate the MSI-X vector table and PBA internally
