If any of the engines hang, you can end up with a deadlock if you schedule dependencies across rings since one of the engines is hung. If you try a newer kernel, GPU reset is enabled and you should be able to recover after a hang. At that point, you can either
restart your applications or use a relevant robustness API to properly handle a reset.</div>

<div>We are using wx5100 for rendering and encoding operations, but sometimes we encounter vce timeout and crash.</div>
<div>Is vce not a independent module in gpu?Why does it affect the rendering module?<br>
</div>
We hope that vce will not affect the rendering module when crashing.<br>
<div>Can I prevent the use of the rendering module from being affected?</div>
