# Arch Linux s390x Port - ${{ github.event.inputs.version }}
|
|
|
|
**🎉 First successful Arch Linux port to IBM s390x mainframe architecture!**
|
|
|
|
${{ github.event.inputs.release_notes }}
|
|
|
|
## 📊 Build Information
|
|
|
|
- **Kernel Version**: ${{ env.KERNEL_VERSION }} (${{ env.KERNEL_SIZE }})
|
|
- **Initramfs**: ${{ env.INITRAMFS_SIZE }} with native s390x binaries
|
|
- **Busybox Version**: ${{ env.BUSYBOX_VERSION }} (statically compiled on z/VM)
|
|
- **Architecture**: IBM s390x (big-endian mainframe)
|
|
- **Status**: ✅ **Fully functional** - boots to emergency shell
|
|
|
|
## 📦 Release Contents
|
|
|
|
This release includes:
|
|
- **vmlinuz-linux-s390x**: Bootable Linux kernel for s390x architecture
|
|
- **initramfs-linux-s390x.img**: Complete initramfs with s390x busybox and utilities
|
|
- **busybox-s390x-static**: Static busybox binary (2.3MB, built on z/VM)
|
|
- **Boot configuration files**: IPL configuration for s390x mainframes
|
|
- **BUILD_INFO.txt**: Detailed build information
|
|
- **SHA256SUMS**: Checksums for all artifacts
|
|
|
|
## 🚀 Quick Start
|
|
|
|
### Test with QEMU s390x:
|
|
```bash
|
|
# Download and extract
|
|
tar -xzf archlinux-s390x-${{ github.event.inputs.version }}.tar.gz
|
|
|
|
# Install QEMU s390x emulation
|
|
sudo pacman -S qemu-system-s390x # Arch Linux
|
|
# or
|
|
sudo apt install qemu-system-s390x # Ubuntu/Debian
|
|
|
|
# Run the system
|
|
qemu-system-s390x \
|
|
-machine s390-ccw-virtio \
|
|
-cpu max \
|
|
-m 2G \
|
|
-kernel vmlinuz-linux-s390x \
|
|
-initrd initramfs-linux-s390x.img \
|
|
-append "console=ttyS0 init=/init" \
|
|
-nographic
|
|
```
|
|
|
|
### Deploy to real IBM mainframe:
|
|
- Use the provided IPL configuration files
|
|
- Boot files are ready for z/VM or LPAR deployment
|
|
|
|
## ✅ What Works
|
|
|
|
- **Complete boot chain**: IPL → kernel → initramfs → emergency shell
|
|
- **Native s390x binaries**: All components built for mainframe architecture
|
|
- **Filesystem operations**: Mount, unmount, and basic file operations via busybox
|
|
- **IBM hardware support**: DASD, QETH, channel I/O drivers included
|
|
- **Console access**: Both 3215 and 3270 terminal support
|
|
|
|
## 🔧 Technical Achievements
|
|
|
|
- **Cross-compilation infrastructure**: Fedora containers with s390x toolchain
|
|
- **mkinitcpio adaptation**: Modified for cross-architecture initramfs building
|
|
- **Static linking solution**: z/VM native compilation eliminates dynamic library issues
|
|
- **Architecture compatibility**: Pure s390x environment without x86_64 contamination
|
|
