...y all the structures for the given > master (IOMMU client device, the one which performs DMA operations). That could be in the probe_device() call-back, no? > I tried to move all the initialization from xlate() to device_probe(), > but such approach doesn't work. device_probe() is exynos_sysmmu_probe(), then yes, this is called before any of the xlate() calls are made. Would it work to keep the iommu_device structures in the sysmmus and also create them for the owners? This isn't really a nice solution but should work the the IOMMU driver until there is a better way to fix this. Regards,...

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
