2019-10-23drm/i915/gt: Try to more gracefully quiesce the system before resetsChris Wilson3-1/+34
If we are doing a normal GPU reset triggered after detecting a long period of stalled work, we can take our time and allow the engines to quiesce. Since we've stopped submission to the engine, and if we wait long enough an innocent context should complete, leaving the engine idle. So by waiting a short amount of time, we should prevent clobbering other users when resetting a stuck context.

During the discussion of patches that enhance the drm_dp_link helpers it was concluded that these helpers aren't very useful to begin with. After all other drivers have been converted not to use these helpers anymore, move these helpers into the last remaining user: Tegra DRM.

2019-10-22drm/i915: Drop assertion that ce->pin_mutex guards state updatesChris Wilson4-24/+0
The actual conditions are that we know the GPU is not accessing the context, and we hold a pin on the context image to allow CPU access. We used a fake lock on ce->pin_mutex so that we could try and use lockdep to assert that access is serialised, but the various different hardirq/softirq contexts where we need to *fake* holding the pin_mutex are causing more trouble. Still it would be nice if we did have a way to reassure ourselves that the direct update to the context image is serialised with GPU execution. In the meantime, stop lockdep complaining about false irq inversions.
