Hi all! I just got back from Open Source Summit, several of the talks I
found interesting were on RISC-V -- a high-level one about the
organizational structure, and Drew Fustini's more technical talk.
In that, he noted that there's a Fedora build *, but it isn't an official
Fedora arch. As I understand it, the major infrastructure blocker is simply
that there isn't server-class hardware (let alone hardware that will build
fast enough that it isn't a frustrating bottleneck).
So, one question is: if we used, say, ARM or x86_64 Amazon cloud instances
as builders, could we build fast enough under QEMU emulation to work? We
have a nice early advantage, but if we don't keep moving, we'll lose that.
But beyond that: What other things might be limits? Are there key bits of
the distro which don't build yet? Is there a big enough risc-v team to
respond to arch-specific build failures? And, do we have enough people to do
QA around release time?
I think the primary problem here is that koji does support neither
external builders nor building on top of qemu emulation.
However, COPR *does* support building on emulated architectures
(that's how its armv7 and s390x support works there).
So, maybe adding a mock configuration for building RISC-V packages in
qemu emulation, with the fedora repositories from
http://fedora.riscv.rocks/koji/ as a base, could work until koji
supports it?
(I think that would involve either adding RISC-V hardware to Fedora
Infrastructure, or adding support for emulated architectures to koji,
or adding support for external builders to koji.)
