I want to initiate a DMA-Transfer for testing.
I stumbled accross a dmatest.c in the kernel sources (drivers/dma). I compiled a Kernel with this Module and tried it without any params.
and i get with dmesgCode:sudo modprobe dmatest
What are the prerequisites for dmatest.ko?Code:__dma_request_channel: fail ((null))
Should I load a special DMA-Engine?z
Is a special param for dmatest.ko required (default should probe anything!?)?
Best Regards
Fuz
