If you can contribute that's the best place to start.

You can borrow kernel driver from Android.

But. Where to find userspace  Mali t720 driver (blob) with OpenCL support? I found only https://github.com/jernejsk/H6-mali-userspace without OpenCL symbols.

no where obviously you are lucky if you get fbdev working and you are looking for open cl very optimistic ;) how can you borrow android kernel btw ?
To make it clear there isn't any working mali t720 driver under linux , none zero nada ;) shame on allwinner and shame on xululong for using a chipset without drivers and shame on us for buying it

Shame but I tested android, it played 4k video, then I got android sources (a lot of gigs), there was the driver source and then I compiled the driver after some corrections the code to my current kernel 4.9...After insmod I got something like /dev/mali, not tested it (the screen is far away now), what I need for now is OpenCL and compute SDK.  I bought the board just for OpenCL support and PCIex, the two features are mis workable , haha, made in China.

i havent seen working gpu aceleration in linux(could be that i wasnt searching to much), only android have good drivers. even with old kernel (BSP) is kind a pain to make everything working on linux.

so for now opi 3 works as media player in android, and some times linux boots up for some testing or as wifi extender (ethernet -> hostapd-> wifi)
