# 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
|
||||

# Arch Linux Kernel Build for s390x
|
||||
|
||||
This directory contains the infrastructure for building the Arch Linux kernel for IBM s390x mainframe architecture.
|
||||
|
||||
## Overview
|
||||
|
||||
The Arch Linux kernel build process has been adapted for cross-compilation to s390x. This maintains compatibility with Arch Linux's kernel patches and configuration while targeting mainframe hardware.
|
||||
|
||||
## Files
|
||||
|
||||
- `PKGBUILD-s390x` - Modified PKGBUILD for s390x cross-compilation
|
||||
- `config-s390x` - Kernel configuration optimized for s390x with Arch Linux defaults
|
||||
- `linux/` - Clone of Arch Linux kernel packaging repository (reference only)
|
||||
|
||||
## Key Differences from Standard Arch Kernel
|
||||
|
||||
1. **Cross-compilation**: Uses `s390x-linux-gnu-gcc` toolchain
|
||||
2. **Architecture-specific config**: Includes s390x drivers (DASD, QETH, channel I/O)
|
||||
3. **No documentation build**: Skipped for cross-compilation efficiency
|
||||
4. **s390x boot image**: Uses `arch/s390/boot/bzImage` instead of x86 boot image
|
||||
|
||||
## Building
|
||||
|
||||
From the project root:
|
||||
|
||||
```bash
|
||||
# Build Arch Linux kernel with patches
|
||||
make arch-kernel
|
||||
|
||||
# Or build vanilla kernel (without Arch patches)
|
||||
make kernel
|
||||
```
|
||||
|
||||
## Configuration
|
||||
|
||||
The `config-s390x` file includes:
|
||||
|
||||
- Standard Arch Linux kernel features (systemd requirements, cgroups, namespaces)
|
||||
- s390x hardware support (DASD storage, QETH networking, z/VM integration)
|
||||
- IBM mainframe specific drivers and console support
|
||||
- Security features (SELinux, AppArmor, BPF)
|
||||
|
||||
## Kernel Versions
|
||||
|
||||
The build process tracks the official Arch Linux kernel version and applies the same patches used in the x86_64 build.
|
||||
|
||||
## Integration with Project
|
||||
|
||||
The built kernel integrates with the existing mkinitcpio-based initramfs generation to create a complete bootable s390x system.
|
||||
|
||||
## Future Improvements
|
||||
|
||||
- Automated patch retrieval for new kernel versions
|
||||
- Integration with Arch Linux package repository
|
||||
- Native s390x package building (when hardware available)
