you don't.  ARM is a registered trademark, and copying what they're
doing is asking for trouble.

instead you take one of the "open gpus" or parts of them and use that.
there's several i've been tracking: MIAOW, Nyuzi, the ORSOC graphics
accelerator - there's surprisingly quite a lot out there.

 it would be on the same silicon, on the same memory bus as the RISC-V
64-bit core.  anything else is too power-hungry.

 correct.  so whatever you get it's guaranteed to be "old".  this is
the sad fact of reverse-engineering: all that effort, with *no
guarantee of success*.... just to get something that's years

no.  ARM has acted so unethically in slandering luc verhaegen and
blackmailing companies that pay him that i am not interested in
supporting their business any more than is absolutely necessary.

 yes.  a _lot_.  however amazingly people are actually doing just
that... even on risc-v where there isn't yet even any actual hardware.

> It is unfortunate people are not able to coordinate such that we can get source code hardware.

 it's still quite a young area of focus.
