Robert Jarzmik e093bf60ca dmaengine: pxa: handle bus errors ... In the current state, upon bus error the driver will spin endlessly, relaunching the last tx, which will fail again and again : - a bus error happens - pxad_chan_handler() is called - as PXA_DCSR_STOPSTATE is true, the last non-terminated transaction is lauched, which is the one triggering the bus error, as it didn't terminate - moreover, the STOP interrupt fires a new, as the STOPIRQEN is still active Break this logic by stopping the automatic relaunch of a dma channel upon a bus error, even if there are still pending issued requests on it. As dma_cookie_status() seems unable to return DMA_ERROR in its current form, ie. there seems no way to mark a DMA_ERROR on a per-async-tx basis, it is chosen in this patch to remember on the channel which transaction failed, and report it in pxad_tx_status(). It's a bit misleading because if T1, T2, T3 and T4 were queued, and T1 was completed while T2 causes a bus error, the status of T3 and T4 will be reported as DMA_IN_PROGRESS, while the channel is actually stopped.
