2020-03-12drm/i915/gen12: Disable preemption timeoutTvrtko Ursulin
Allow super long OpenCL workloads which cannot be preempted within the default timeout to run out of the box. v2: * Make it stick out more and apply only to RCS.

2020-03-11drm/i915/gem: Take a copy of the engines for context_barrier_taskChris Wilson
When applying the context-barrier, we only care about the current engines, as the next set of engines will be naturally after the barrier. So we can skip holding the ctx->engines_mutex while constructing the request by taking a sneaky reference to the i915_gem_engines instead.

Since the semaphore fence may be signaled from inside an interrupt handler from inside a request holding its request->lock, we cannot then enter into the engine->active.lock for processing the semaphore priority bump as we may traverse our call tree and end up on another held request.

2020-03-11drm: Remove drm dp mst destroy_connector callbacksPankaj Bharadiya
drm_dp_mst_topology_mgr_cbs.destroy_connector callbacks are identical amongst every driver and don't do anything other than cleaning up the connector((drm_connector_unregister()/drm_connector_put())) except for amdgpu_dm driver where some amdgpu_dm specific code in there.

Converts various instances of the printk based drm logging macros to the struct drm_device based logging macros in i915/display/intel_hotplug.c. In some cases, this involves extracting the drm_i915_private pointer from the drm_device struct to be used in the logging macros.

2020-03-10drm/i915: Improve the start alignment of bonded pairsChris Wilson
Always wait on the start of the signaler request to reduce the problem of dequeueing the bonded pair too early -- we want both payloads to start at the same time, with no latency, and yet still allow others to make full use of the slack in the system. This reduce the amount of time we spend waiting on the semaphore used to synchronise the start of the bonded payload.
