Subject: Re: [PATCH v4 0/7] Support for GPU ACD feature on Adreno X1-85

Hi,

Sorry I should have gave an update on this: I don't think the lockups are
related to this patch series, the same problem happens without applying these
patches. It seems to increase by a lot the chances that a GPU lockup happens at
start, however, so I could use that to debug the real problem.

I'm using the firmwares imported from Windows, the Yoga Slim 7x is not in
linux-firmware. I understood that the firmware files used by the Slim 7x are
quite old, maybe it could be the problem.

The GMU version:

> [drm] Loaded GMU firmware v4.3.17

Thanks
