Hi Chris/Daniel, The patch is helping in some of the side-effects due to gpu boost. I still need to get more data. I will keep the thread updated. Thanks Deepak On Thursday 12 June 2014 03:02 PM, Daniel Vetter wrote: Adding Deepak for testing, this hopefully alleviates the bad side-effects o

2014-06-12 Thread Chris Wilson
Make the assumption that media workloads are not as latency sensitive for __wait_seqno, and that upclocking the GPU does not affect the BLT engine. Under that assumption, we only wait to forcibly upclock the GPU when we are stalling for results from the render pipeline. Signed-off-by: Chris Wilson
