I do have to ask, what kind of hardware are you using? Riscv64 systems
tend to be seen as something akin to raspberry pi, but if building
rust (which takes at least ten minutes on a 2x64 core x86 server) is
now feasible, I'd like to know how :)

I am using a high performance riscv64 SOC TH1520, an example of the Wujian 600’s platform released by T-Head. You can find more information from:

Thanks.

Right, but are you actually running bitbake on this board, which
according to the page has only 4 cores? And if you do, what targets
are you building and how long do they take?

Otherwise I am not sure what riscv rust-snapshot is useful for. It
would help if you explain the use case.

Yes, now bitbake is running on this board.
The example TH1520 is 4cores, but Wujian 600 supports more cores.
It does take a lot of time to run on this board now, and I don’t see the actual significance at the moment, but I think this is part of the riscv ecology and will play a role in the near future.
Thanks.

Yes, but this needs to be of practical use, and not just an experiment
that you ran. I'd rather defer this until there is for example a
broadly available cloud resource where you can run bitbake and get
completion times similar to that of established architectures. Keep in
mind that someone has to update those checksums with each rust upgrade
for example. And test that things work and do not regress.

Yes, I agree with your point of view and understand the impact of this,
the current time may not be mature enough,
thanks for your review.
