Completely changing code for the tool isn't probably a good idea. It might even get you severally flamed on LKML :) The recent threads are informative (ok to read, bad to be in). > > Incidentally, when I asked the person working these changes, they had reported 0 functional errors had been fixed by the checkpatch changes. A lot of the noise was typedef reduction. I'm not familiar with checkpatch, but I guess the purpose is not to highlight functional issues. However, there are functional issues, but it makes sense to cleanup the code first: there's no point in analyzing code that is never used. > <snip> > >> Err, I got confused about the CE/Link, I meant the xdctools... or >> whatever is needed to compile DSP nodes.

You should be able to compile the ARM side. Indeed, if I put myself the open source cap I can create ARM side applications, but then I need something running on the DSP in order to test them. If I put my corporate cap I can do that, and see that effectively, my ARM application works. But how are maintainers supposed to test this? At the very least I would expect a base image binary, and a dummy dsp node that simply copies the buffers received so that anyone can get their hands dirty with the dsp bridge. Otherwise it's just some code that nobody can test (hard to merge that way). > A few years back I had heard about some people even successfully running Linux on the C6x DSP. I think it ran well, but kind of neat all the same. DSPBIOS or other tiny OSes work much better there. Interesting, another platform to conquer for Linux ;) Best regards. -- Felipe Contreras -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
