Hi Ville

I found your patch looking at issue VLK-65591, seems like for some reason
cannot apply this workaround on JasperLake and end up with an error: 

```
<3> [463.126159] i915 0000:00:02.0: [drm] ERROR GT0: engine workaround lost on application! (reg[7000]=0x0, relevant bits were 0x0 vs expected 0x8000)

```

When the workaround is verified, 15th bit is not set. Is it possible that
this workaround is not available ? I would be grateful for any tips.



Best regards,
Sebastian Brzezinka
