exactly … they start to aggressively throw themselves into the market becoming competitive, have you noticed the gpu? it’s from imagination, former ex gpu suppliers for Apple … I found this video, they had already announced that they are also working on a RISC-V cpu
Hi yes. I backed it. But it has not the power of the laptop of course. But nice still and nice to tinker with. 
Not surprising, since they were doing MIPS before and the MIPS foundation annoucned that they are abandoning the MIPS architecture to support RISC-V instead.
However the PowerVR GPUs are not exactly known for being friendly with open source, I guess this will have to change if we want to see good support in most operating systems (and not just binary blobs for Linux).
we will see, I am optimistic, this time the world is really changing, I am referring especially to the European and US chips act. Besides Imagination, closing the business with Apple, I don’t think it has reasons to create obstacles, now everyone is opening up with opensource drivers even nvidia has given up, they are more convenient for everyone, and if they want to speed up their popularity on these new RISC-V platforms, so much the better that they use opensource divers
If I recall right there was recently a release of a PowerVR graphics driver for older PowerVR graphics units?
Also isnt the M1 APU a PowerVR derivat which gets currently reverse engineered?
I have not deepened the research, but it seems to make sense with the landing on the risc-v architecture…
If I understand correctly this one is planned to have a fully open source vulkan and OGLES3.x driver (without blobs I think). There is some info here: IMG BXE4-32 GPU Open Source Plan - GPU related - RVspace Forum
Edit: Actually I think it will have firmware blobs but open source shader compiler (so we should be able to have a haiku driver in theory!) Open Source GPU Driver - Imagination Developer
do you think they chose the same methodology as nvidia? to make closed source firmware and opensource drivers?
i like where riscV is heading, now to get us companies behind it
It seems likely, that is the approach recommended by the Free Software Foundation in their “Respects Your Freedom” recommendations for hardware: if the software is embedded in a device and not upgradeable, it is not software but firmware, and then it doesn’t need to be free.
Personally I think this is a bit stupid in terms of free software and open hardware, but hey, it means the “intelligence” moves inside the graphics card and the drivers get simpler so we can more easily port them to Haiku. So let’s at least enjoy that
Yea, the approach looks like this: they obfuscate what really happens between hardware and firmware and provide you with connection tubes to do what you want with the drivers … at least there is good that you can build on it a coherent integration with the rest of the operating system … it’s not the best, but it’s definitely better than it was before.
to be honest, win the complexity of graphics drivers and hardware, this is a win period. better to let them fix the firmware.
What’s the current “best cheap board” to play with this? There seem to be some Nezha “clones” popping up, plus the LicheeRV and carrier, or is there only support for the high end platforms so far?
Haiku doesn’t support any cheap boards at the moment. Haiku developers might take an interest in VisionFive 2 or Pine64 Star64 soon-ish, but that is not certain. There are even cheaper boards, but they can’t even run desktop Linux, so I wouldn’t bother.
With latest Haiku recent code, I can boot Haiku on MangoPi Pro (Allwinner Nezha d1 chip based).
