Subject: [PATCH v2 1/4] PCI: Add setup_platform_service_irq hook to struct pci_host_bridge
Date: Wed, 14 Nov 2018 20:17:55 +0530 [thread overview]
Message-ID: <1542206878-24587-2-git-send-email-bharat.kumar.gogada@xilinx.com> (raw)
In-Reply-To: <1542206878-24587-1-git-send-email-bharat.kumar.gogada@xilinx.com>
As per section 6.2.4.1.2, 6.2.6 in PCIe r4.0 error interrupts can
be delivered with paltform specific interrupt lines.
Add setup_platform_service_irq hook to struct pci_host_bridge.
Some platforms have dedicated interrupt line from root complex to
interrupt controller for PCIe services like AER.
This hook is to register platform IRQ's to PCIe port services.
