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 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
Qiang Liu (4):
Talitos: Support for async_tx XOR offload
fsl-dma: remove attribute DMA_INTERRUPT of dmaengine
fsl-dma: change release process of dma descriptor for supporting async_tx
fsl-dma: use spin_lock_bh to instead of spin_lock_irqsave
Qiang Liu (7):
Talitos: Support for async_tx XOR offload
fsl-dma: remove attribute DMA_INTERRUPT of dmaengine
fsl-dma: change release process of dma descriptor for supporting async_tx
fsl-dma: move the function ahead of its invoke function
fsl-dma: use spin_lock_bh to instead of spin_lock_irqsave
fsl-dma: fix a warning of unitialized cookie
fsl-dma: add memcpy self test interface
