Six years ago, most devices could not handle this type of restriction efficiently. Things have improved on the high end; but the low end devices, are still very similar to what we had back in the day. Even today, I would be very cautious of deploying an architecture where no devices can be touched from user space. This will really box many driver developers into a corner they can't get out of. Is that worth it for support of graphics pipeline hot plugging? If you would like to get
It not's the graphics cards that are being hotplugged, it's other cards in the system. If xfree hasn't coordinated with the kernel, the kernel hotplug code could easily map the new hardware right on top of the Xfree HW.
This doesn't sound like a huge problem, XFree could simply inform the kernel about what it has done, or use a kernel api to do the mappings for it. It doesn't seem to require moving the driver to kernel space.
