From dc9f06ca81e6e16d062ec382701142a3a2ab3f7d Mon Sep 17 00:00:00 2001 From: Pavel Fedin Date: Thu, 15 Oct 2015 16:44:52 +0300 Subject: kvm: Pass PCI device pointer to MSI routing functions In-kernel ITS emulation on ARM64 will require to supply requester IDs. These IDs can now be retrieved from the device pointer using new pci_requester_id() function. This patch adds pci_dev pointer to KVM GSI routing functions and makes callers passing it. x86 architecture does not use requester IDs, but hw/i386/kvm/pci-assign.c also made passing PCI device pointer instead of NULL for consistency with the rest of the code.
