2019-07-17drm/amdkfd: Remove GWS from process during uninitJoseph Greathouse
If we shut down a process without having destroyed its GWS-using queues, it is possible that GWS BO will still be in the process BO list during the gpuvm destruction. This list should be empty at that time, so we should remove the GWS allocation at the process uninit point if it is still around.

Apply the same setting to SH_MEM_CONFIG and VM_CONTEXT1_CNTL. This makes the noretry param no longer KFD-specific. On GFX10 I'm not changing SH_MEM_CONFIG in this commit because GFX10 has different retry behaviour in the SQ and I don't have a way to test it at the moment.

2019-07-11drm/amdkfd: fix cp hang in evictionEric Huang
The cp hang occurs in OCL conformance test only on supermicro platform which has 40 cores and the test generates 40 threads. The root cause is race condition in non-protected flags. The fix is to add flags of is_evicted and is_active(init_mqd()) into protected area.

Oversubscription of queues or processes results in poor performance mostly because HWS blinbly schedules busy and idle queues, resulting in poor occupancy if many queues are idle.

2019-06-11drm/amdkfd: Simplify eviction state logicFelix Kuehling
Always mark evicted queues with q->properties.is_evicted = true, even queues that are inactive for other reason. This simplifies maintaining the eviction state as it doesn't require updating is_evicted when other queue activation conditions change. On the other hand, we now need to check those other queue activation conditions whenever an evicted queues is restored. To minimize code duplication, move the queue activation check into a macro so it can be maintained in one central place.
