Something like this?

        case I915_PARAM_HAS_GPU_RESET:
- value = i915.enable_hangcheck && intel_has_gpu_reset(dev_priv);
+               value = i915.enable_hangcheck;
+               if (value)
+                       value = intel_has_reset_engine(dev_priv) ? 2 :
+                               intel_has_gpu_reset(dev_priv) ? 1 : 0;
                break;

(you'll probably think of a nicer way to do it)

I'm also sending the patch with the changes to support parallel resets, some other patches need rebase after this change, but I'm holding on those.

Thanks,
