They managed to pick the one mobile GPU vendor that has zero open-source drivers for their chips and a reputation for horribly messy and unstable proprietary code.
Another board for the landfill, forever doomed to some 80s throwback Unix timeshare shell application.
In IMG's defense, the way that their drivers and firmware are micro optimized for the specific IP core version and use case by the host software was one of their competitive advantages. It's one of the reasons why their cores were some of the fastest and most efficient for the years that they still had plenty of capital rolling in to support that model.
You'd expect that kind of thing to be brittle when you don't have source access, but the drivers themselves were remarkably clean when I spent some time reversing them. It's just a shame that they're so afraid of open source too, because the above really compounds that pain.
