  • How does that apply for a driver written for/in the V4L2 framework, where the start and end methods are not actually situated in the code written by me? Commented Mar 30, 2022 at 15:00
  • Dunno. I should think it has hooks of some sort or it is a bit daft, but you're better off asking about that on Stack Overflow; there's very little kernel mod programming going on here (I'm just familiar with the basics). Commented Mar 30, 2022 at 15:13
  • Having completed these tutorials, are we entitled to call ourselves "kernel programmers"? Commented Mar 31, 2022 at 15:07
  • You've have to ask the LKML about that ;) Since most of the kernel can in theory be compiled as loadable modules, including various bits of critical infrastructure like networking and peripheral access, drawing a line between "just a module" and "the kernel proper" seems arbitrary. But you do have to actually write some code and make it work @Seamus -- ever use C? You'll love it. Separates the boys from the men so to speak. Or the children from the adults, to be more inclusive.

  • Just between us - I do not like C. But like the line in the movie, "I said I didn't have much use for it - I never said I didn't know how to use it" LOL Commented Mar 31, 2022 at 16:03
