Pipelining buffer moves

2016-06-06 Thread Christian König 
Hi everyone,

this set of patches moves waiting for TTM BOs to become idle before moving them 
into the driver callbacks and the CPU copy fallback function.

Then the amdgpu driver is patched to completely remove this premove idle wait.

Doing this improves swapping buffers back in on command submission. Improving 
evictions (swapping things out) is the next step.

Please review and/or comment,
Christian.
