git bisect found commit 29aaab2b5f55cc6d9a84f58ce2bb8607e76a9dde as the culprit. reverting it makes 11.0.0-rc2 work on my hw. for some reason it does not like commit 29aaab2b5f55cc6d9a84f58ce2bb8607e76a9dde Author: Grigori Goronzy <greg@chown.ath.cx> Date: Wed Jun 24 03:38:02 2015 +0200 winsys/radeon: align BO size to page size This is the basic granularity for BO allocations. The alignment also helps with BO reuse by the cached bufmgr. This results in a huge 45% speedup in Metro 2033 Redux on my test system. The game relies on buffer orphaning with very small buffers (hundreds of bytes in size) and that did not work efficiently before. This change may also affect other applications and games.
