Hi, Kumar... > I'm not aware of anyone work on such a thing.
*Sigh*... no holiday for me this summer .-( > I'd be more than happy > to accept patches for it. I know several of us have written some APIs > on top of the DMA for 85xx. Those however are non-standard APIs. But is there any code available for recycling? Are there any Freescale-FAE's with some snippets? (Hello, world!) I am about to start more or less from scratch and re-invent the wheel. > What APIs exist for general purpose DMA engines? Last time I looked at > this problem nothing really existed. :-) I was wondering about that, too... Maybe we can get some basics from this one: Linux/Documentation/DMA-API.txt And, well, code from: asm-ppc/ppc4xx_dma.h arch/ppc/syslib/ppc4xx_sgdma.c and from the pci.h subsystem. Hmm... and there is the factor that it's difficult to get resources in my project for all that. :-((( Best greets, Clemens Koller _______________________________ R&D Imaging Devices Anagramm GmbH Rupert-Mayer-Str. 45/1 81379 Muenchen Germany http://www.anagramm.de Phone: +49-89-741518-50 Fax: +49-89-741518-19
