Xiaomi announced their HyperOS, and info is sparse on the anglo-web. I searched in Chinese forums and eventually found (randomly, happy I did though) dedicated forums and saw folks were getting randomly chosen to upgrade if they had a newer Xiaomi device. My fingers are crossed, hopefully I'll get it early.

What I am trying to say it I would imagine there is documentation and it simply isn't accessible, the nerds or interest groups of course know where to look. By accessible I don't mean blocked, rather it's not openly advertised as perhaps the amount of interest isn't there yet or isn't known to be there.

I get the impression they're still doing a lot of tweaking on it, so maybe they'll publish a spec once it's finalized a bit more.

Definitely would be interesting to see how optimized stuff runs on it. I really hope they integrate the whole SOC idea where there is shared memory between the CPU and the GPU too cause that removes the whole bus bottleneck.
