[Intel-gfx] [PATCH] drm/i915/selftests: Make the kernel_context pulse explicit

[Intel-gfx] [PATCH] drm/i915/selftests: Make the kernel_context pulse explicit

[Chris Wilson]

As we disable the heartbeat, and prevent the engine parking, the switch
to kernel context is not automatic. Make it an explicit switch instead.
