From: Thierry Reding <treding at nvidia.com> Most IOMMU drivers only need to free the memory allocated for each reserved region. Instead of open-coding the loop to do this in each driver, extract the code into a common function that can be used by all these drivers. Changes in v2: - change subject prefix to "iommu: virtio: " for virtio-iommu.c driver Thierry Thierry Reding (5):

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
