-The following 4 patches enabling fsl-dma and talitos offload raid
+Hi,
+
+The following 7 patches enabling fsl-dma and talitos offload raid
operations for improving raid performance and balancing CPU load.
-Write performance will be improved by 40% tested by iozone. CPU load
-will be reduced by 8%.
+Write performance will be improved by 25-30% tested by iozone.
+Write performance is improved about 2% after using spin_lock_bh replace
+spin_lock_irqsave.
+CPU load will be reduced by 8%.
+
+Changes in V4:
+ - fix an error in talitos when dest addr is same with src addr, dest
+ should be freed only one time if src is same with dest addr;
+ - correct coding style in fsl-dma according to Ira's comments;
+ - fix a race condition in fsl-dma fsl_tx_status(), remove the interface
+ which is used to free descriptors in queue ld_completed, this interface
+ has been included in fsldma_cleanup_descriptor(), in v3, there is one
+ place missed spin_lock protect;
+ - split the original patch 3/4 up to 2 patches 3/7 and 4/7 according to
+ Li Yang's comments.
+ - fix a warning of unitialized cookie;
+ - add memory copy self test in fsl-dma;
+ - add more detail description about use spin_lock_bh() to instead of
+ spin_lock_irqsave() according to Timur's comments;
+
+Changes in v3:
+ - change release process of fsl-dma descriptor for resolve the
+ potential race condition
+ - add test result when use spin_lock_bh replace spin_lock_irqsave
+ - modify the benchmark results according to the latest patch
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
