So it's needed to unblock the current scanout render pipeline before the run state is changed to make sure the guest receives the response for the current frame submission. v2: Giving some time for the fence to be signaled before flushing the pipeline v3: Prevent redundant call of gd_hw_gl_flushed by checking dmabuf and fence_fd >= 0 in it (e.g. during and after eglClientWaitSync in gd_change_runstate).
