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
