General performance has indeed increased, however I can clearly notice "hickups" during major load on the GPU. Like when starting mozilla apps or wine apps; this was not noticeable with previous v7+locking patchset.

As you said it is like old UMS code, and actually glxgears FPS is comparable (if not better); so the only minor issue is the hickups that I am experiencing. These hickups also hang the mouse for some seconds, so I suppose it is some locking on the GPU pipe, but I can't read the changes in your v8 patch so just suppositions.

Anyway the patch is perfectly mature for upstream in my opinion, and is indeed the best one we have up to now. Please grab my Tested-By line from previous comments.
