APM X-Gene v1 SoC supports its own implementation of MSI, which is not compliant to GIC V2M specification for MSI Termination. There is single MSI block in X-Gene v1 SOC which serves all 5 PCIe ports. This MSI block supports 2688 MSI termination ports coalesced into 16 physical HW IRQ lines and shared across all 5 PCIe ports. v3 changes: 1. Implement MSI support using PCI MSI IRQ domain 2. Only use msi_controller to store IRQ domain v2 changes: 1. Use msi_controller structure 2. Remove arch hooks arch_teardown_msi_irqs and arch_setup_msi_irqs .../devicetree/bindings/pci/xgene-pci-msi.txt | 63 ++++ MAINTAINERS | 8 + arch/arm64/boot/dts/apm/apm-storm.dtsi | 27 ++ drivers/pci/host/Kconfig | 6 + drivers/pci/host/Makefile | 1 + drivers/pci/host/pci-xgene-msi.c | 407 +++++++++++++++++++++ drivers/pci/host/pci-xgene.c | 21 ++ 7 files changed, 533 insertions(+) create mode 100644 Documentation/devicetree/bindings/pci/xgene-pci-msi.txt create mode 100644 drivers/pci/host/pci-xgene-msi.c -- 1.9.1
