Chris Wilson b428d57006 drm/i915/gt: Reset execlists registers before HWSP ... Upon gt resume, we first poison then sanitize the engine. However, our testing shows that gen9 will very rarely retain the poisoned value from the HWSP mappings of the execlists status registers. This suggests that it is reading back from the HWSP, so rejig the register reset. v2: Maybe RING_CONTEXT_STATUS_PTR is write masked. It is.
