Write performance will be improved by 40% tested by iozone. CPU load will be reduced by 8%. Changes in v2: - rebase onto cryptodev tree - split the patch 3/4 up to 3 independent patches - remove the patch 4/4, the fix is not for cryptodev tree Qiang Liu (4): Talitos: Support for async_tx XOR offload fsl-dma: remove attribute DMA_INTERRUPT of dmaengine fsl-dma: change the release process of dma descriptor fsl-dma: use spin_lock_bh to instead of spin_lock_irqsave drivers/crypto/Kconfig | 9 + drivers/crypto/talitos.c | 410 ++++++++++++++++++++++++++++++++++++++++++++++ drivers/crypto/talitos.h | 53 ++++++ drivers/dma/fsldma.c | 76 +++------ 4 files changed, 496 insertions(+), 52 deletions(-)
