WebJul 9, 2024 · The snoop behavior is decided by both device and IOMMU. Device can set a no-snoop attribute in DMA request to force the non-coherent behavior, while IOMMU may support a configuration which enforces DMAs to be coherent (with the no-snoop attribute ignored). No-snoop DMA requires the driver to manually flush caches for observing the … WebCache snooping simply tells the DMA controller to send cache invalidation requests to all CPUs for the memory being DMAed into.
