2016-08-08dmaengine: ioatdma: Add error handling to ioat driverDave Jiang2-16/+126
Adding error handling to the ioatdma driver so that when a read/write error occurs the error results are reported back and all the remaining descriptors are aborted. This utilizes the new dmaengine callback function that allows reporting of results.

2016-08-08dmaengine: add support to provide error result from a DMA transationDave Jiang1-5/+17
Adding a new callback that will provide the error result for a transaction. The result is allocated on the stack and the callback should create a copy if it wishes to retain the information after exiting. The result parameter is now defined and takes over the dummy void pointer we placed in the helper functions previously. dmaengine drivers should start converting to the new "callback_result" callback in order to receive transaction results.

2016-08-08dmaengine: Add helper function to prep for error reportingDave Jiang1-0/+72
Dmaengine does not provide a way to pass back the result from a DMA transaction through the callback function. We are adding dmaengine helper function in order to prep for a mechanism that allow result status and other information through the callback. The initial conversion will make the existing driver use these new helper functions but retain the original behavior of the code. However, the helper functions paves a way towards adding the result parameter through callback.

2016-08-08dmaengine: ioatdma: fix uninitialized array usageDave Jiang1-1/+1
Static analysis showed that unitialized array is being used for compare. At line 850 when a dma_mapping_error() occurs, it jumps to dma_unmap. At this point, dma_srcs has not been initialized. However, the code after dma_unmap label checks dma_srcs for a comparison and thus is comparing to random garbage in the array. Given that when dest_dma is being mapped this is the first instance of mapping DMA memory and failed, there is really nothing to be cleaned up and thus should jump to free_resources label instead.

Implement the function which wait until a dma channel is stopped to have a synchronization point. This also protects the pxad_remove() from races, such as spurious interrupts while removing the driver, because : - as long as there is one dma channel requested, ie. dma_chan_get() but no dma_chan_put(), the try_module_get() of dma_chan_get() prevents the remove() routine from running - when the last channel is released, ie. the last dma_chan_put() is called, if there is a running DMA, pxad_synchronize() is called - pxad_synchronize() waits for the channel to stop, which in turn ensures on pxa architecture that the interrupt cannot be fired anymore Reported-by: Vinod Koul <vinod.koul@intel.com> Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
