Architectures/RISC-V/SpacemiT-Koji-Builder

Configuring Banani Pi / Jupiter as a Koji Builder

Prepare Fedora

• Download the image: wget https://openkoji.iscas.ac.cn/pub/dist-repos/dl/Milk-V/Jupiter/images/latest/k1-fedora-minimal.img.gz
• Extract it: gzip -d k1-fedora-minimal.img.gz
• Write it to an SD Carddd if=k1-fedora-minimal.img of=/dev/sdX bs=64M status=progress

Recommended Steps

• Resize /boot. (partition 5) The image only has a 256MB /boot partition, which is too small for installing multiple kernels.
• Move / (partition 6) to an NVME disk and resize it. If you do this mount /boot and update root=/dev/mmcblk0p6 to root=/dev/nvme0n1p1 in extlinux/extlinux.conf

Boot and Complete

• Install your storage device(s) and boot
• Replace /etc/yum.repos.d/fedora-riscv-koji.repo with

[fedora-riscv-koji]
name=Fedora RISC-V Koji
baseurl=http://fedora.riscv.rocks/repos/f41-build/latest/riscv64/
enabled=1
gpgcheck=0

[fedora-riscv-openkoji]
name=Fedora RISC-V Koji
baseurl=http://openkoji.iscas.ac.cn/kojifiles/repos/f41-build/latest/riscv64/
enabled=0
gpgcheck=0

• dnf -y update

Optional: Install updated SpacemiT kernel repo

Rust projects have been observed failing to build with 6.1.15 kernel that comes on the image. It also does not have selinux enabled, modules necessary for firewalld to run, etc.

I am attempting to maintain and keep up to date an LTS 6.6 kernel that more closely resembles a Fedora config with patches from https://gitee.com/bianbu-linux/linux-6.6/ until we have a proper mainline kernel. The Bianbu repo is based off 6.6.36. At the time of writing I have been able to keep it up to the current LTS release, 6.6.52.

• Add /etc/yum.repos.d/spacemit.repo

[spacemit]
name=spacemit
enabled=1
gpgcheck=0
baseurl=https://people.redhat.com/jmontleo/fedora/linux/releases/41/spacemit/riscv64/
priority=98

[spacemit-source]
name=spacemit-source
enabled=0
gpgcheck=0
baseurl=https://people.redhat.com/jmontleo/fedora/linux/releases/41/spacemit/source/tree

• This script is not required, but will automatically update /boot/extlinux/extlinux.conf when a new kernel is installed. To use it save it as /etc/kernel/install.d/99-update-extlinux.install, ensuring the cmdline root= settings matches your root device.

done

• chmod +x /etc/kernel/install.d/99-update-extlinux.install
• Change SELINUX=enforcing to SELINUX=permissive in /etc/selinux/config
• touch /.autorelabel
• dnf -y install ... ... ... ...
• dnf -y remove ... ... ... ...
• Run /etc/kernel/install.d/99-update-extlinux.install one manually now.
• reboot, let relabel complete
• Change SELINUX=permissive back to SELINUX=enforcing in /etc/selinux/config
• reboot (or just setenforce 1)

Install and Configure Koji

• systemctl mask tmp.mount
• Create /etc/systemd/system/kojid.service.d/override.conf

[Service]
Restart=always
RestartSec=10min

• reboot
• Add /etc/yum.repos.d/koji.repo (Nothing past 1.33 works right or me with the current server)

Proxy Configuration

Builders can use a lot of bandwidth. A squid proxy can cut this down substantially
