>This company makes GPUs?

Yes, and they've been around for a while. If you're old enough, you might remember the name "PowerVR".

Today, they mostly license GPU designs to SoC vendors. You'll find their designs in e.g. Android phones.

Notably, JH7110 (RISC-V SoC used in VisionFive2 and Star64) uses one of their recent GPUs.

does this mean you can run, say, modern openCL code on smth like a VisionFive2?

Oomph-wise, they claim a good 4x over what the Raspberry Pi 4/400 have. Note that rPi's is known to be anemic due to serious memory bandwidth bottlenecks, barely able to keep up with filling a 1080p screen.

Currently they do not support the specific variant used in JH7110, but they seem to both be variants of the same architecture.

JH7110 has the BXE-4-32MC1[0], whereas the driver currently supports the BXS-4-64-MC1[1].

No idea about compute, and AIUI openCL suport in mesa3d is still a disaster for all drivers.

I'm curious how you can tell that it was BXS-4-64-MC1 that was supported. I looked and couldn't find that.

Besides the JH7110 there's TH1520 and it's using the BXM-4-64-MC1, also not supported, but 2X the speed of BXE-4-64-MC1 if I understand it correctly.

Yes; and if you used an iPhone before 2017, you used GPU made by them.

Technically, their new GPUs are also directly descended from them. Though, deviating more and more each generation.
