I wonder, what are the negatives of moving modesetting to kernel from
userspace ? Will we be loosing some functionality (at least temperarily) ?
How will, say, choosing mode on external distplay work ?
No negative sides to it, really. Speed will also benefit (not directly
from KMS but rather from TTM/GEM) since the biggest problem with the
open source drivers right now is the lack of a memory manager (this is
the main reason why the closed source drivers perform better by an order
of magnitude, even though they have the memory manager in user space).
I'm not sure about the mode for external displays. The configuration
will probably still happen at the same place, though under the hood the
work will be done by the kernel.
