I think a starting point is to talk to Fedora Infrastructure and
Release Engineering about this.
Also, is there any server-class hardware that can be racked for us to
power builds? We don't typically do emulated builds because they're
incredibly slow.
That said, Fedora RISC-V is probably a good blueprint for how to get
started bootstrapping LoongArch in Fedora. Those folks are here on
this list and they can reply with some details (I don't remember
exactly how they did it).
Thanks! We have completed the bootstrap steps, and we want to learn more
about how to further interface with Fedora's build system.
