Subject: [PATCH v5 17/17] iommu/arm-smmu: Do not advertise IOMMU_CAP_INTR_REMAP anymore
Date: Wed, 4 Jan 2017 13:32:26 +0000 [thread overview]
Message-ID: <1483536746-2725-18-git-send-email-eric.auger@redhat.com> (raw)
In-Reply-To: <1483536746-2725-1-git-send-email-eric.auger@redhat.com>
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 takes into account the MSI domain MSI remapping
capability, let's correct this.
