Hi All, I am facing a problem that Async layer is not able to find any registered DMA channel for Async memory copy operation. DMA driver is working properly i.e. Standalone DMA functionality is working fine and it registers successfully with the Async layer. But in return, Async layer is not able to find any DMA channel when it requires it for async memory copy operations and thus Async layer goes for synchronous memory copy operations. Linux version :- Linux-2.6.23-rc4 Board :- 837x Has anybody tested functionality of Async layer for memory copy/XOR operations?? Thanks in Advance, Thanks & Regards Surender - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
