My colleauge I've been working with on this hasn't yet reported CPU stalls using iommufd though, so I'm not sure which path iommufd takes to know where to place cond_resched(). Blindly stumbly through it, my best guess right now is arriving at the loop in iopt_fill_domains_pages(), called through iommufd_vfio_map_dma(). Am I close?
