[Mesa-dev] [PATCH] amdgpu/winsys: adjust IB size based on buffer wait time

2016-04-15 Thread Grigori Goronzy
Small IBs help to reduce stalls for workloads that require a lot of synchronization. On the other hand, if there is no notable synchronization, we can use a large IB size to slightly improve performance in some cases. This introduces tuning of the IB size based on feedback on the average buffer wa
