mv_xor: fix race in tasklet function

2011-01-03T09:39:26Z

use mv_xor_slot_cleanup() instead of __mv_xor_slot_cleanup() as the former function aquires the spin lock that needed to protect the drivers data. Cc: Signed-off-by: Saeed Bishara Signed-off-by: Dan Williams

dmaengine: at_hdmac: fix buffer transfer size specification

2010-12-14T08:39:29Z

Buffer transfer size is the number of transfers to be performed in relation with the width of the _source_ interface. So in the DMA_FROM_DEVICE case, it should be the register width that should be taken into account. Signed-off-by: Nicolas Ferre Signed-off-by: Dan Williams

fsldma: fix issue of slow dma

2010-12-13T22:05:27Z

Fixed fsl dma slow issue by initializing dma mode register with bandwidth control. It boosts dma performance and should works with 85xx board. Signed-off-by: Forrest Shi Signed-off-by: Li Yang Signed-off-by: Dan Williams

dmaengine i.MX SDMA: initialize on module_init

2010-12-07T23:38:07Z

The firmware framework gets initialized during fs_initcall time, so we are not allowed to call request_firmware earlier. Signed-off-by: Sascha Hauer Signed-off-by: Dan Williams

dma : EG20T PCH: Fix miss-setting DMA descriptor

2010-12-07T23:07:08Z

Currently, in case of using scatter/gather mode, head of data is not sent to destination. The cause is second descriptor address is set to NEXT. The NEXT must have head of descriptor address. This patch sets head of descriptor address to the NEXT. Acked-by: Yong Wang Signed-off-by: Tomoya MORINAGA [dan.j.williams@intel.com: fixed up usage of virt_to_phys()] Signed-off-by: Dan Williams

intel_mid_dma: fix section mismatch warnings

Rename intel_mid_dma_pci to intel_mid_dma_pci_driver to pick up the applied annotations of that suffix. Reported-by: Signed-off-by: Dan Williams

dmaengine: imx-sdma: fix bug in buffer descriptor initialization

2010-12-04T23:03:46Z

Currently while submitting scatterlists with more than one SG entry the DMA buffer address from the first SG entry is inserted into all initialized DMA buffer descriptors. This is due to the typo in the for_each_sg() loop where the scatterlist pointer is used for obtaining the DMA buffer address and _not_ the SG list iterator. As a result all received data will be written only into the first DMA buffer while reading. While writing the data from the first DMA buffer is send to the device multiple times. This caused the filesystem destruction on the MMC card when using DMA in mxcmmc driver. Signed-off-by: Anatolij Gustschin Acked-by: Sascha Hauer Signed-off-by: Dan Williams
