469 This is needed by some interrupt controllers to route MSI and MSI-X interrupts.

859 MSI and MSI-X interrupts are available to PCI devices as one or more
862 A driver must ask the PCI bus to allocate MSI or MSI-X interrupts
867 before it can use MSI or MSI-X
872 resource if MSI or MSI-X interrupts have been allocated,
873 and attempts to allocate MSI or MSI-X interrupts will fail if the
877 A driver is only allowed to use either MSI or MSI-X,
882 function returns the maximum number of MSI messages supported by the
885 If the device does not support MSI,
902 or if the system has a shortage of available MSI messages.
916 Note that MSI only supports message counts that are powers of two;
921 function is used to release any allocated MSI or MSI-X messages back
923 If any MSI or MSI-X
935 function returns the maximum number of MSI-X messages supported by the

947 containing the MSI-X Pending Bit Array (PBA) for device
954 If the device does not support MSI-X,
962 containing the MSI-X vector table for device
969 If the device does not support MSI-X,
986 or if the system has a shortage of available MSI-X messages.
992 For MSI-X messages,
995 resource identifies the index in the MSI-X table of the
997 A resource ID of one maps to the first index of the MSI-X table;
1010 Unlike MSI,
1013 The BARs containing the MSI-X vector table and PBA must be
1028 to determine the pending status of the MSI-X message at table index
1060 The array maps directly to the MSI-X table in that the first entry in
1061 the array specifies the message used for the first entry in the MSI-X
1067 that no message should be assigned to the corresponding MSI-X table entry,

1079 each MSI-X table entry with a non-zero vector will have an associated

1158 The PCI bus driver should allocate the MSI-X vector table and PBA internally
