Single patch is more easy to manage.
The first patch of this driver should comes a whole.
Benchmarks and debugfs are not the very basic parts.
In the V2,
Thomas told me that if we implement our own TTM-based memory manager,
we will also have the possibility of implementing a faster console.
Back to that time I do not even know the bandwidth of our hardware.
1) The bandwidth of copying buffer from the system RAM to system RAM;
2) The bandwidth of copying buffer from the system RAM to dedicated VRAM;
3) The bandwidth of copying buffer from the dedicated VRAM to system RAM;
We can make the right decision only when we know the various bandwidth
listed as above.
How to implement it.
