[PATCH] iommu/vt-d: add sysfs file to print out all domains

This patch adds a new sysfile for intel-iommu driver which prints out all allocated iommu domains: $> cat /sys/class/iommu/dmar0/intel-iommu/domains did | pci_device_name 1 | :00:14.0 2 | :00:1d.0 3 | :00:1f.0 4 | :02:00.0 5 | :02:00.1 6 | :02:00.2 7 |

[PATCH v2] iommu/arm-smmu-v3: Warn about missing IRQs

It is annoyingly non-obvious when DMA transactions silently go missing due to undetected SMMU faults. Help skip the first few debugging steps in those situations by making it clear when we have neither wired IRQs nor MSIs with which to raise error conditions. Signed-off-by: Robin Murphy

[PATCH] iommu/mediatek: Fix driver name

There exist two Mediatek iommu drivers for the two different generations of the device. But both drivers have the same name "mtk-iommu". This breaks the registration of the second driver: Error: Driver 'mtk-iommu' is already registered, aborting... Fix this by changing the name for first
