Hmm you can't be binary like that. I think there are 3 classes of devices
around :
- no context support at all : old radeon, old intel
- multiple fifos, no hw context switching : newer radeon, newer intel
- multiple fifos, hw context switching : all nvidia
The third case obviously will never require any kind of state re-emitting.
