ioat3.2 adds xor offload support for up to 8 sources. It can also perform an xor-zero-sum operation to validate whether all given sources sum to zero, without writing to a destination. Xor descriptors differ from memcpy in that one operation may require multiple descriptors depending on the number of sources. When the number of sources exceeds 5 an extended descriptor is needed. These descriptors need to be accounted for when updating the DMA_COUNT register. Signed-off-by: Dan Williams <dan.j.williams@intel.com> |
