This patchset doesn't actually add any hardware support. I want to see what people think of this interface, and would like to adjust it before I do an implementation on nvc0. TBH, I can't say I really love either the dd nor the gallium functions I'm adding. However I also can't think of a particularly cleaner way of doing this.
I had an original version of this code which unconditionally wrote a 1 for GL_QUERY_AVAILABLE, but my latest thinking is that you could potentially have totally unsynchronized engines that were writing these things out, and so for a query to not be available is something that could legitimately make sense. So I'm leaving that up to the driver. Also for consistency, I'm having the (mesa) driver write the GL_QUERY_TARGET value in rather than the core, as it's unwieldy to do it in the core. A hypothetical driver might also want to do or not do various synchronization. As there's no HW support, this is wholly untested beyond compilation.
