From 248f7d54f00c4fed7faece4df1e5996177e5e127 Mon Sep 17 00:00:00 2001 From: Andrew Jones Date: Tue, 30 Jun 2015 14:14:38 +0200 Subject: [PATCH 09/11] arm_gicv2m: set kvm_gsi_direct_mapping and kvm_msi_via_irqfd_allowed Message-id: <1435673680-9996-7-git-send-email-drjones@redhat.com> Patchwork-id: 66572 O-Subject: [AArch64 RHEL-7.2 qemu-kvm-rhev PATCH 6/8] arm_gicv2m: set kvm_gsi_direct_mapping and kvm_msi_via_irqfd_allowed Bugzilla: 1231929 RH-Acked-by: Igor Mammedov RH-Acked-by: Laszlo Ersek RH-Acked-by: Michael S. Tsirkin Author: Eric Auger After introduction of kvm_arch_msi_data_to_gsi, kvm_gsi_direct_mapping now can be set on ARM. Also kvm_msi_via_irqfd_allowed can be set, depending on kernel irqfd support, hence enabling VIRTIO-PCI with vhost back-end.
