And why? I think it's perfect solution. The only problem IMHO is DGA. DGA
is not a direct competitor with DirectX because it lacks some features and
needs root privileges to use it (because it mmap()s video ram). But this
is NOT a kernel issue either: according the answer to my old letter to the
XFree mailing list it can be possible (I mean DGA access without root rights)
but it would require major modifications inside XFree so it's not planned
in the near future. What do you want to move into kernel space? IMHO the best
way is to keep as less functionalities into kernel space as possible. Other
things can be implemented in user space as well.
