Each PCI device under a root complex is uniquely identified by its Requester ID (AKA RID). A Requester ID is a triplet of a Bus number, Device number, and Function number. MSIs may be distinguished in part through the use of sideband data accompanying writes. In the case of PCI devices, this sideband data may be derived from the Requester ID. A mechanism is required to associate a device with both the MSI controllers it can address, and the sideband data that will be associated with its writes to those controllers. This commit adds the `msi-map` property for PCI nodes, therefore creating MSI mapping for each PCI device. Signed-off-by: Henry Wang <Henry.Wang@arm.com> |
