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):

Hi, here is the second version of this patch-set. The first version with some more introductory text can be found here: https://lore.kernel.org/lkml/20200407183742.4344-1-joro at 8bytes.org/ Changes v1->v2: * Rebased to v5.7-rc1 * Re-wrote the arm-smmu changes as suggested by Robin Murphy * Re-worked the Exynos patches to hopefully not break the driver anymore * Fixed a missing

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

Convert the AMD iommu driver to the dma-iommu api. Remove the iova handling and reserve region code from the AMD iommu driver. Change-log: V6: -add more details to the description of patch 001-iommu-amd-Remove-unnecessary-locking-from-AMD-iommu-.patch -rename handle_deferred_device to iommu_dma_deferred_attach -fix double tabs in 0003-iommu-dma-iommu-Handle-deferred-devices.patch V5: -Rebase on

Convert the AMD iommu driver to the dma-iommu api. Remove the iova handling and reserve region code from the AMD iommu driver. Change-log: V4: -Rebase on top of linux-next -Split the removing of the unnecessary locking in the amd iommu driver into a seperate patch -refactor the "iommu/dma-iommu: Handle deferred devices" patch and address comments v3: -rename dma_limit to dma_mask -exit

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
