[Intel-gfx] [PATCH 2/3] drm/i915: Attach a fb to the load-detect pipe

We need to ensure that we feed valid memory into the display plane attached to the pipe when switching the pipe on. Otherwise, the display engine may read through an invalid PTE and so throw an PGTBL_ER exception. As we need to perform load detection before even the first object is allocated for t
