fb_info, fb_fix_screeninfo : questions

[Romain D. <do...@ir...>]

Hello,

I have a few questions on the subject of porting a driver
to ruby:

1) is it legit to extend fb_info ? i.e. using another
struc xxfb_info w/ a fb_info field first, and using
that in place of regular fb_info (like it's done
in 2.4 and in the ruby atyfb)

2) where is filled fb_fix_screeninfo ? skeletonfb
doesn't mention it. I believe it's in _set_par,
but I'd like to be sure.

3) are the optional functions (_ioctl, _fill_rect...)
 replaced by NULL or by the cfb_ or fb_ generic
in the _ops struct ?

TIA
