Looking in the i810 driver, it seems like the ringbuffer is flushed and disabled until the X server calls EnterVT again, and AGP memory is unbound. How is the client generally notified about this?
The server holds the hw lock until the VT comes back.
With the client still having access to the unbound AGP pages as AGP side addresses ?
Someone else will have to answer this one...
But in general, I don't think that any of the mappings available to the client are revoked or in fact changed in any way on VT switch.
