Fedora/RISC-V: Runnable stage 4 disk images

We’ve now got:

  1. An autobuilder.
  2. A multithreaded QEMU.
  3. A Fedora RPMs repository.
  4. A bootable disk image.

It’s unpolished and minimal at the moment, but what you can do today (if you have a Fedora 27+ x86_64 host):

  1. Enable the rjones/riscv copr and install riscv-qemu.
  2. Download the stage4-disk.img, and bbl and uncompress the disk image.
  3. Run this command:
    qemu-system-riscv64 \
        -nographic -machine virt -m 2G -smp 4 \
        -kernel bbl \
        -append "console=ttyS0 ro root=/dev/vda init=/init" \
        -device virtio-blk-device,drive=hd0 \
        -drive file=stage4-disk.img,format=raw,id=hd0 \
        -device virtio-net-device,netdev=usernet \
        -netdev user,id=usernet
    
  4. Inside the guest drop a repo file into /etc/yum.repos.d containing:
    [local]
    name=RPMS
    baseurl=https://fedorapeople.org/groups/risc-v/RPMS/
    enabled=1
    gpgcheck=0
    
  5. Use tdnf --releasever 27 install ... to install more packages.

RISC-V Tokyo

Today (was) RISC-V Day 2017 Tokyo at the University of Tokyo (programme in English, more information in English). My colleague Wei Fu gave a talk on the status of Fedora on RISC-V. I hope it was recorded somewhere. If it appears online I’ll update this post.
