From 5018c8d5ef0c172592eb98cf10e253d47b544ba8 Mon Sep 17 00:00:00 2001 From: Eric Auger Date: Thu, 19 Jan 2017 20:58:03 +0000 Subject: [PATCH] iommu/arm-smmu: Do not advertise IOMMU_CAP_INTR_REMAP anymore IOMMU_CAP_INTR_REMAP has been advertised in arm-smmu(-v3) although on ARM this property is not attached to the IOMMU but rather is implemented in the MSI controller (GICv3 ITS). Now vfio_iommu_type1 checks MSI remapping capability at MSI controller level, let's correct this.
