AMD RadeonSI & R600g Gallium3D Tests On Mesa 11.0 + DRM-Next

[marek]

Hmm, btw... it's quite big omission there is no way to dump raw gallium hud data into file. I found HUD quite useful for getting idea what goes on, but sometimes I need to do automated/batch processing of this kind of data and Gallium HUD would not help with that. This is very sad, since it actually got most code and data in hand and it literally about being able to write it to some file.

Patches welcome.

Hm. It actually looks relatively easy.

Anyone who knows c and mesa well enough to do this in a way that makes sure it doesn't hurt performance and is in line with how things in mesa are done can probably do it properly pretty quickly .
