None, we don't really have that information anywhere since we don't 
really have a swapped state.

See when the application allocates a BO in VRAM the kernel driver is 
free to swap it out to GTT and still do command submission. Only when it 
is further swapped out to the CPU domain it is not accessible any more.

So what you can do is to look at the BOs in the CPU domain, but this 
only gives you a certain hint on what's going on.

Christian.
