Hi, This serie refactors the mv_xor in order to support the latest Armada 38x features, including the PQ support in order to offload the RAID6 PQ operations. Not all the PQ operations are supported by the XOR engine, so we had to introduce new async_tx flags in the process to identify un-supported operations. Please note that this is currently not usable because of a possible regression in the RAID stack in 4.1 that is being discussed at the moment here: https://lkml.org/lkml/2015/5/7/527 Let me know what you think, Maxime Lior Amsalem (7): dmaengine: mv_xor: add support for a38x command in descriptor mode dmaengine: mv_xor: Enlarge descriptor pool size dmaengine: mv_xor: improve descriptors list handling and reduce locking dmaengine: mv_xor: bug fix for racing condition in descriptors cleanup async_tx: adding mult and sum_product flags dmaengine: mv_xor: add support for a38x RAID6 support ARM: mvebu: a38x: Enable A38x XOR engine features Maxime Ripard (1): dmaengine: mv_xor: Rename function for consistent naming Documentation/devicetree/bindings/dma/mv-xor.txt | 2 +- arch/arm/boot/dts/armada-38x.dtsi | 20 +- crypto/async_tx/async_raid6_recov.c | 4 +- drivers/dma/mv_xor.c | 459 +++++++++++++++-------- drivers/dma/mv_xor.h | 32 +- include/linux/dmaengine.h | 4 + 6 files changed, 326 insertions(+), 195 deletions(-) -- 2.4.0 -- To unsubscribe from this list: send the line "unsubscribe dmaengine" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
