BTW, i tried this WE to look at porting the pm3fb driver to the new API, doing a complete rewrite (well, basically starting again from tridentff, tdfxfb and skeletonfb, and getting the code as needed from current pm3fb, which has a lot of unneeded stuff in it). I have not much time though, so it will go slowly. I thought i may as well write a little HOWTO or something such on the way of doing this. Since i have not much fbdev writing experience, maybe i am a good candidate for writing such a thing. I wanted, in the first step, to do just a basic unaccelerated fbdev driver, without mode changes and anything fancy, and once this works, add things incrementally. I believe this approach will be good for future fbdev driver writters. Anyway, now for my question. skeletonfb says that check_var, set_par, setcolreg, pan_display and blank functions are optional or not required. Is that true, and in case i don't want to provide them, whay do i put in the fb_ops structure ? Later, in the fb_ops structure, only set_par, blank and pan_display are labeled as optional.
