@iska@mstdn.starnix.network That is a very sane thing to assume if this device wasn't designed with linux in mind.
I don't get where are we going with this? Okay, maybe you can spend some time on it and get the freedreno shit working, maybe you can spend a shit-ton of time to reverse engineer and make a proper device tree… To do what, get other OS running on a seven year old phone? Just get a PinePhone, it's like $200 — it will cost less than your time spent on making it work.
