A few other ideas to ponder:

1. Looking into DPM, I found this commit for 5.1-rc1 that looks interesting:

https://github.com/torvalds/linux/commit/7ca881a8651bdeffd99ba8e0010160f9bf60673e

Looks like it exposes "ppfeatures" interface on Vega 10 and later GPU,
including some code for Vega 20.

2. I also found two interesting commits that pertain to "doorbell" register
initialization on Vega 20. Also from 5.1-rc1. Might be related to setting up
the GPU ASICs . I must admit I'm not exactly sure what these do . . .
