We have a couple of users of the iommu API at the moment outside of GPUs: * drivers/media/platform/omap3isp/isp.c * drivers/remoteproc/remoteproc_core.c * drivers/infiniband/hw/usnic/usnic_uiom.c * drivers/vfio/ I assume we will see a few more over time. The vfio case is the most important one here, since that is what the iommu API was designed for. Arnd -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
