Hi, here is a patch-set to remove all calls of iommu_group_get_for_dev() from the IOMMU drivers and move the per-device group setup and default domain allocation into the IOMMU core code. This eliminates some ugly back and forth between IOMMU core code and the IOMMU drivers, where the driver called iommu_group_get_for_dev() which itself called back into the driver. The patch-set started as a

This patchset converts the intel iommu driver to the dma-iommu api. While converting the driver I exposed a bug in the intel i915 driver which causes a huge amount of artifacts on the screen of my laptop. You can see a picture of it here: https://github.com/pippy360/kernelPatches/blob/master/IMG_20191219_225922.jpg This issue is most likely in the i915 driver and is most likely caused by the
