I don't fully agree. The kernel will do the actual HW banging, but we want things like EDID overrides per monitor models, persistent configuration saved to storage etc... all of that beeing pretty nasty to do in the kernel. > > Probably moving > > some of the higher level mode management out of the kernel driver > > down to this userland library. > > Bad idea. I have mixed feeling on that. Keith Packard seem to prefer the library approach. I don't know for sure what Linus prefers here. Currently, I feel we are trying to do too much in the kernel, and that will become increasingly painful to manage as we get multiple head & geometry stuff getting in the picture.
