Hi Christoph, In the habanalabs driver we have moved to use dma_mmap_coherent (to match dma_alloc_coherent - see commit https://lkml.org/lkml/2020/8/29/252) Since then, we are plagued by the kernel log message that gavin has mentioned, as we are mostly running in our C/I environment with 5.4. I wondered if you know if there was any fix to that in the more recent kernels ? If not, can I help to fix that ? Thanks, oded _______________________________________________ iommu mailing list [email protected] https://lists.linuxfoundation.org/mailman/listinfo/iommu
