Hmm, Right,

bool intel_has_gpu_reset(const struct intel_gt *gt)
{
        if (!i915_modparams.reset)
                return NULL;

        return intel_get_gpu_reset(gt);
}

bool intel_has_reset_engine(const struct intel_gt *gt)
{
        if (i915_modparams.reset < 2)
                return false;

        return INTEL_INFO(gt->i915)->has_reset_engine;
}

just engine-reset. Still that wasn't the intention when setting -1.
