I've added a small test utility for the TTM buffer object functionality
It benchmarks various simple buffer operations like binding, writing,
reading in some
various memory types / regions: system, GTT and cache coherent GTT.
It's not really complete and one could for example add options for
buffer size etc.
Typical output for a 4MB buffer is attached. Experimenting with the
buffer size will show bottlenecks,
for example the binding / unbinding latency when binding to uncached GTT.
It's also an example of how a small general-purpose DRI client (XvMC
etc.) can be made.
In the end, the DRI client protocol code should probably end up in a
