Testing Jeromes Code
As you can see in this picture there there seem some issues in the radeon-rewrite branch. I only could trigger this in blender.
I noticed a few rendering issues when looking web sites using epiphany that use background images for the body. Nothing worse because only the background looks weird while the content is looking normal.
Video scaling is broken. You only see the upper left quarter of the video. As you can see in this picture clipping caused by windows in front of the window cause an even more strange behaviour. The upper part seems to be working more or less fine. The rest is ... well, weird :-)
And last but not least:
glxgears is noticably slower ... but who cares? glxgears is not a benchmark. And ioquake3 bases games are running slower without me ever noticing it.
Respecting the changes done to radeon this is a rather short list of issues. Large central parts of the radeon driver at all levels have been rewritten. There is a new kernel module using TTM and providing KMS. You got a brand new command submission method used by the DDX and by mesa. You are using DRI2 and a rewritten radeon mesa driver. I must admit that I'm pretty impressed of the stability of such early code. Let's say thanks to Jerome Glisse, Dave Airlie, Nicolai Haehnle, Alex Deucher and who else was involved working on the radeon code. Thanks guys!
