The iProc PCIe MSI support deploys an event queue-based implementation. Each event queue is serviced by a GIC interrupt and can support up to 64 MSI vectors. Host memory is allocated for the event queues, and each event queue consists of 64 word-sized entries. MSI data is written to the lower 16-bit of each entry, whereas the upper 16-bit of the entry is reserved for the controller for internal processing. Each event queue is tracked by a head pointer and tail pointer. Head pointer indicates the next entry in the event queue to be processed by the driver and is updated by the driver after processing is done. The controller uses the tail pointer as the next MSI data insertion point. The controller ensures MSI data is flushed to host memory before updating the tail pointer and then triggering the interrupt. MSI IRQ affinity is supported by evenly distributing the interrupts to each CPU core. MSI vector is moved from one GIC interrupt to another in order to steer to the target CPU. Therefore, the actual number of supported MSI vectors is: M * 64 / N where M denotes the number of GIC interrupts (event queues), and N denotes the number of CPU cores. This iProc event queue-based MSI support should not be used with newer platforms with integrated MSI support in the GIC (e.g., giv2m or gicv3-its).

There is a single MSI block in X-Gene v1 SOC which serves all 5 PCIe ports. This MSI block supports 2048 MSI termination ports coalesced into 16 physical HW IRQ lines and shared across all 5 PCIe ports. As there are only 16 HW IRQs to serve 2048 MSI vectors, to support set_affinity correctly for each MSI vectors, the 16 HW IRQs are statically allocated to 8 X-Gene v1 cores (2 HW IRQs for each cores). To steer MSI interrupt to target CPU, MSI vector is moved around these HW IRQs lines. With this approach, the total MSI vectors this driver supports is reduced to 256.

This controller can be found on (mostly) all Broadcom BCM470X / BCM5301X ARM SoCs. The driver found in the Broadcom SDK does some more stuff, like setting up some DMA memory areas, chaining MPS and MRRS to 512 and also some PHY changes like "improving" the PCIe jitter and doing some special initialization for the 3rd PCIe port. This was tested on a bcm4708 board with 2 PCIe ports and wireless cards connected to them. PCI_DOMAINS is needed by this driver, because normally there is more than one PCIe controller and without PCI_DOMAINS only the first controller gets registered. This controller gets 6 IRQs; the last one is trigged by all IRQ events.
