Chris Wilson ca65fc0d8e drm/i915/gt: Always send a pulse down the engine after disabling heartbeat ... Currently, we check we can send a pulse prior to disabling the heartbeat to verify that we can change the heartbeat, but since we may re-evaluate execution upon changing the heartbeat interval we need another pulse afterwards to refresh execution. v2: Tvrtko asked if we could reduce the double pulse to a single, which opened up a discussion of how we should handle the pulse-error after attempting to change the property, and the desire to serialise adjustment of the property with its validating pulse, and unwind upon failure.
