Subject: [PATCH v7 19/36] iommu/mediatek: Allow IOMMU_DOMAIN_UNMANAGED for PCIe VFIO
Date: Tue, 3 May 2022 15:14:10 +0800 [thread overview]
Message-ID: <20220503071427.2285-20-yong.wu@mediatek.com> (raw)
In-Reply-To: <20220503071427.2285-1-yong.wu@mediatek.com>
Allow the type IOMMU_DOMAIN_UNMANAGED since vfio_iommu_type1.c always call
iommu_domain_alloc. The PCIe EP works ok when going through vfio.
