It's handy for RVV as we can set some qemu options that help flush out potential compiler issues that might not be observable in currently available hardware. YMMV of course.

I can't vouch for kernel debugging, but for userspace most of the LLVM CI infra I maintain across various RISC-V configs is done in qemu-system (via a slightly funky cross-compile and then run tests under qemu-system setup) and I've not had false test failures in a released version of QEMU.

I'm assuming an Arch host that does have an handy opensbi package but you could just grab that from the relevant .deb. Also assumes a new enough e2fsprogrs to have the super handy -d option

If you're looking at something that might be reproducible with qemu, then my recipe at muxup.com/2024q4/rootl... should work (by all means just use `sudo debootstrap` directly rather than my rootless wrapper, it was a bit of a personal sidequest!).

I don't think there are other good generally available options right now unfortunately. Assuming qemu-system won't work for you, it might be worth seeing if riscv.epcc.ed.ac.uk could be appropriate (CC @nickbrown-hpc.bsky.social)

There's a lot of implied menace in "We've got your $VENDOR parcel" emails

And there's been a _lot_ more back and forth since then. Seems like Int is winning the argument so far.
