In the source is suggested to read /Documentation/DMA-mapping.txt and the v4l2-api.

Thanks for the fun with your new stuff, but I don't know much about the saa7134. Many people here know much much more. What you saw was me somewhat overdriven, when it goes out towards 2.6.0 now and that we do not left something let laying around here. Lucky I was to have the driver fine now for so long, but I was not fully aware of annoying problems others have to face and that says all. Gerds advise to use at least 2.4.22 to follow the changes was serious! On 2.4.21 the kernelpatch you took, that was tested by me, not the maybe whatever version of v4l2 in the snapshot directory, what can be in use now. Also that patch you used 11-v4l2-api-2.4.21-rc4.diff.gz is not complete and brings not the saa7134 driver and the bttv as usual, only the now again old changes for v4l2. The saa7134-0.2.9 snapshot I use on it is not longer in the snapshot directory and the actual one will not build any longer on 2.4.21, but saa7134-0.2.8 also was running. So it tends to become a historical research ... and I don't get my own things up. For the rest is what you say and maybe some outcome from dmesg after modprobe. Greetings Hermann --
