Hello, could anyone explain to me briefly what are the principles of programming DMA control so as to be used by the webcam ? (or indicate me a Web address with some information) I skimmed a little through the cpia sources for the 2.2 kernel, but dma programming was done controllong the ECR, a method which is considered obsolete, judging by the comments I found in the 2.4 kernel sources. Thank you Nicola
