So what do you need in the kernel?
- support for text mode on graphics boards that support text mode
- support for text mode on graphics boards that don't support text mode
(perhaps with some basic support for rectangular blits, to speed up
scrolling)
- support for setting a specific video mode
Yep, that's all. Graphics acceleration should be done in user space, just mmap
the acceleration registers.
There's even a project for it, and it works, on m68k, PPC, AXP, ia32, and soon
on ARM:
