From 0ae1625177aba9ac70beb1556615530ddb18086d Mon Sep 17 00:00:00 2001 From: Jan Kiszka Date: Mon, 2 Jul 2012 14:38:47 +0200 Subject: pci: Add INTx routing notifier This per-device notifier shall be triggered by any interrupt router along the path of a device's legacy interrupt signal on routing changes. For simplicity reasons and as this is a slow path anyway, no further details on the routing changes are provided. Instead, the callback is expected to use pci_device_route_intx_to_irq to check the effect of the change. Will be used by KVM PCI device assignment and VFIO.
