2016-07-01drm/i915: Delay queuing hangcheck to wait-requestChris Wilson
We can forgo queuing the hangcheck from the start of every request to until we wait upon a request. This reduces the overhead of every request, but may increase the latency of detecting a hang. However, if nothing every waits upon a hang, did it ever hang? It also improves the robustness of the wait-request by ensuring that the hangchecker is indeed running before we sleep indefinitely (and thereby ensuring that we never actually sleep forever waiting for a dead GPU). As pointed out by Tvrtko, it is possible for a GPU hang to go unnoticed for as long as nobody is waiting for the GPU. Though this rare, during that time we may be consuming more power than if we had promptly recovered, and in the most extreme case we may exhaust all memory before forcing the hangcheck. Something to be wary off in future.

2016-07-01drm/i915/shrinker: Flush active on objects before countingChris Wilson
As we inspect obj->active to decide how many objects we can shrink (we only shrink idle objects), it helps to flush the active lists first in order to have a more accurate count of available objects.

2016-07-01drm/i915/bxt: Fix sanity check for BIOS RC6 setupImre Deak
BXT BIOS has two options related to GPU power management: "RC6(Render Standby)" and "GT PM Support". The assumption so far was that disabling either of these options would leave RC6 uninitialized. According to my tests this isn't so: for a proper RC6 setup we only need the "GT PM Support" option to be enabled while the "RC6" option only controls whether RC6 is left enabled or not by BIOS. OTOH we were missing a few checks to ensure a proper RC6 setup. Add these now and don't fail the sanity check if RC6 is disabled. This fixes a problem where RC6 remains disabled after reloading the driver, since we explicitly disable RC6 during unloading. v2: - Print a debug message about the BIOS enabled RC state.
