From 32e1cccf68123bcd357c0115567d2ce3453cd3ed Mon Sep 17 00:00:00 2001 From: Yong Wu Date: Tue, 3 May 2022 15:14:10 +0800 Subject: iommu/mediatek: Allow IOMMU_DOMAIN_UNMANAGED for PCIe VFIO 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.
