Hi,
today I've pushed preliminary support for ARB_occlusion_query extension.
It's based on mesa radeon-rewrite branch. With this extension enabled r300 driver advertises GL 1.5. Yupi!
Currently I've tested it only on my RV535 (X1650) without KMS. Everything seems to be working. Unfortunately ARB_oq for SW TCL is broken now, and proper implementation will take some time. It also probably won't work with KMS enabled.
Besides some conformance testing apps I've tested it under sauerbraten game - it gives nice performance boost (especially on bigger maps), so there is an extra motivation for you to test - it can make your favorite game playable
Please test, and post your results (tested apps, performance boosts/regressions).
You can find the code here: http://cgit.freedesktop.org/~osiris/mesa/ (occlusion-query branch)
