[Mesa-dev] [PATCH 3/3] r600g: Implement timer queries.

[Mathias Fröhlich]

Hi,

Attached is a patch to implement timer queries for r600g.

I have not found much documentation about the frequency of the gpu's timestamp 
counter. But What I have found indicates that it runs at 27MHz which is 
implemented in the patch and gives 'reasonable' query results with osgviewer.

Please review and may be apply.

Thanks,
 Mathias
