-Hi all,
-
-The following 8 patches enabling fsl-dma and talitos offload raid
+The following 4 patches enabling fsl-dma and talitos offload raid
operations for improving raid performance and balancing CPU load.
-
-These patches include talitos, fsl-dma and carma module (caram uses
-some features of fsl-dma).
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 v6:
- - swap the order of original patch 3/6 and 4/6;
- - merge Ira's patch to reduce the size of original patch;
- - merge Ira's patch of carma in 8/8;
- - update documents and descriptions according to Ira's advice;
-
-Changes in v5:
- - add detail description in patch 3/6 about the process of completed
- descriptor, the process is in align with fsl-dma Reference Manual,
- illustrate the potential risk and how to reproduce it;
- - drop the patch 7/7 in v4 according to Timur's comments;
-
-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.
