Sorry, I didn't quite get this. Do you mean that if I do allyesconfig, SHOW_ALL_DRIVERS would get enabled, but not otherwise? > But we should not annouyt the user just to get better build coverage - which > is why hiding irrelevant symbols is good. No disagreement there. But I must say good build coverage is also important (I broke a powerpc fb driver compilation with my mmap changes, and after fixing the compilation I introduced a warning...). So I think it's a worthy goal to have most of the drivers arch-independent, and make it possible to build them if the user so wants. I'll do a bit experimenting with fb drivers to see how the SHOW_ALL_DRIVERS would work. And if there are any other fb drivers than omapfb that actually can be compiled on other archs. Tomi
