The blob_encap and blob_decap functions were not flushing the dcache before passing data to CAAM/DMA and not invalidating the dcache when getting data back. Therefore, blob encapsulation and decapsulation failed with errors like the following due to data cache incoherency: "40000006: DECO: desc idx 0: Invalid KEY command" To ensure coherency, we require the key_mod, src and dst buffers to be aligned to the cache line size and flush/invalidate the memory regions. The same requirements apply to the job descriptor. Tested on an i.MX6Q board. Reviewed-by: Sumit Garg <sumit.garg@nxp.com> Signed-off-by: Clemens Gruber <clemens.gruber@pqgruber.com> |
