# DKMS Implementation Plan for Particle-OS
|
||||
|
||||
## Overview
|
||||
|
||||
This document outlines the step-by-step implementation plan for adding DKMS (Dynamic Kernel Module Support) to Particle-OS, following the successful patterns established by uBlue-OS.
|
||||
|
||||
## Phase 1: Core DKMS Infrastructure
|
||||
|
||||
### 1.1 apt-layer DKMS Integration
|
||||
|
||||
#### Add DKMS Commands to apt-layer.sh
|
||||
```bash
|
||||
# New DKMS-specific commands
|
||||
--dkms-status # Show DKMS module status
|
||||
--dkms-list # List installed DKMS modules
|
||||
--dkms-install <module> # Install DKMS module
|
||||
--dkms-remove <module> # Remove DKMS module
|
||||
--dkms-rebuild <module> # Rebuild DKMS module
|
||||
--dkms-rebuild-all # Rebuild all DKMS modules
|
||||
--dkms-clean <module> # Clean DKMS build environment
|
||||
--dkms-logs <module> # Show DKMS build logs
|
||||
--dkms-rollback # Rollback failed DKMS installation
|
||||
```
|
||||
|
||||
#### Implementation Steps:
|
||||
1. **Add DKMS dependency checking** in apt-layer.sh
|
||||
2. **Create DKMS layer management functions**
|
||||
3. **Implement DKMS hook system**
|
||||
4. **Add kernel header management**
|
||||
5. **Create DKMS atomic transaction support**
|
||||
|
||||
### 1.2 DKMS Configuration System
|
||||
|
||||
#### Create DKMS Configuration Files
|
||||
```bash
|
||||
/usr/local/etc/particle-os/dkms/
|
||||
├── dkms-settings.json # DKMS configuration
|
||||
├── kernel-versions.json # Kernel version tracking
|
||||
├── modules.json # Installed modules list
|
||||
└── hooks/ # DKMS hooks directory
|
||||
├── pre-install.sh
|
||||
├── post-install.sh
|
||||
├── pre-remove.sh
|
||||
└── post-remove.sh
|
||||
```
|
||||
|
||||
#### DKMS Settings Configuration

# DKMS and NVIDIA Support in Particle-OS
|
||||
|
||||
## Overview
|
||||
|
||||
Particle-OS supports DKMS (Dynamic Kernel Module Support) and NVIDIA drivers, following the successful patterns established by uBlue-OS. This enables users to install proprietary drivers, kernel modules, and other software that requires kernel compilation while maintaining the immutable system architecture.
|
||||
|
||||
## Why DKMS Support is Essential
|
||||
|
||||
### Desktop Use Cases
|
||||
- **NVIDIA Gaming**: Proprietary NVIDIA drivers for optimal gaming performance
|
||||
- **Hardware Support**: Custom kernel modules for specialized hardware
|
||||
- **Virtualization**: VMware, VirtualBox, and other virtualization tools
|
||||
- **Network Cards**: Custom drivers for enterprise network adapters
|
||||
- **Storage Controllers**: RAID controllers and specialized storage hardware
|
||||
|
||||
### uBlue-OS Inspiration
|
||||
uBlue-OS successfully implements DKMS support through:
|
||||
- **NVIDIA Variants**: Dedicated builds with NVIDIA drivers pre-installed
|
||||
- **DKMS Integration**: Automatic kernel module compilation and installation
|
||||
- **Atomic Updates**: DKMS modules are rebuilt when kernel updates occur
|
||||
- **Rollback Safety**: Failed DKMS builds don't break the system
|
||||
|
||||
## Particle-OS DKMS Architecture
|
||||
|
||||
### 1. DKMS Layer Management
|
||||
|
||||
```bash
|
||||
# Create a DKMS-enabled layer
|
||||
apt-layer ubuntu-base/24.04 dkms-base/24.04 dkms
|
||||
|
||||
# Install NVIDIA drivers with DKMS
|
||||
apt-layer dkms-base/24.04 nvidia-gaming/24.04 nvidia-driver-535
|
||||
|
||||
# Install other DKMS modules
|
||||
apt-layer dkms-base/24.04 vmware/24.04 open-vm-tools-dkms
|
||||
```
|
||||
|
||||
### 2. Kernel Synchronization
|
||||
|
||||
```bash
|
||||
# DKMS automatically rebuilds when kernel updates
|
||||
apt-layer ubuntu-base/24.04 kernel-update/24.04 linux-generic-hwe-24.04
|
||||
|
||||
# Verify DKMS modules are rebuilt
|
||||
apt-layer --dkms-status
|
||||
```
|
||||
|
||||

|
||||
|
||||
If DKMS module installation fails:
|
||||
|
||||
```bash
|
||||
# 1. Check DKMS status for errors
|
||||
sudo apt-layer --dkms-status
|

|
||||
|
||||
```bash
|
||||
# 1. Check NVIDIA Prime status
|
||||
sudo apt-layer --nvidia-status
|
||||
|
||||
# 2. Reconfigure NVIDIA Prime
|
||||
sudo apt-layer --nvidia-prime-configure
|
||||
|
||||
# 3. Check if prime-select is available
|
||||
which prime-select
|
||||
|
||||
# 4. Manually switch GPU
|
||||
sudo prime-select nvidia
|
||||
sudo prime-select intel
|
||||
sudo prime-select query
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
### 1. Always Use Atomic Operations
|
||||
|
||||
Particle-OS DKMS commands use atomic transactions with automatic rollback:
|
||||
|
||||
```bash
|
||||
# Safe installation with rollback on failure
|
||||
sudo apt-layer --dkms-install module-name version
|
||||
|
||||
# Safe removal with rollback on failure
|
||||
sudo apt-layer --dkms-remove module-name version
|
||||
```
|
||||
|
||||
### 2. Check Status After Operations
|
||||
|
||||
Always verify that operations completed successfully:
|
||||
|
||||
```bash
|
||||
# Check DKMS status after installation
|
||||
sudo apt-layer --dkms-status
|
||||
|
||||
# Check NVIDIA status after driver installation
|
||||
sudo apt-layer --nvidia-status
|
||||
```
|
||||
|
||||
### 3. Rebuild After Kernel Updates
|
||||
|
||||
Always rebuild DKMS modules after kernel updates:
|
||||
|
||||
```bash
|
||||
# After system upgrade
|
||||
sudo apt-layer upgrade
|
||||
sudo apt-layer --dkms-rebuild-all
|
||||
```
|
||||
|
||||
### 4. Use Auto-Detection for NVIDIA Drivers
|
||||
|
||||
Let Particle-OS auto-detect the optimal NVIDIA driver:
|
||||
|
||||
```bash
|
||||
# Auto-detect is usually the best choice
|
||||
sudo apt-layer --nvidia-install auto
|
||||
```
|
||||
|
||||
### 5. Configure NVIDIA Prime for Laptops
|
||||
|
||||
For laptops with dual GPUs, configure NVIDIA Prime:
|
||||
|
||||
```bash
|
||||
# Configure for automatic GPU switching
|
||||
sudo apt-layer --nvidia-prime-configure
|
||||
sudo apt-layer --gpu-switch auto
|
||||
```
|
||||

# uBlue-OS Kernel Module Architecture Analysis
|
||||
|
||||
## Overview
|
||||
|
||||
This document analyzes how uBlue-OS handles kernel modules and hardware support, and provides recommendations for implementing similar functionality in Particle-OS.
|
||||
|
||||
## uBlue-OS Architecture Analysis
|
||||
|
||||
### 1. **akmods System** ([uBlue-OS akmods](https://github.com/ublue-os/akmods))
|
||||
|
||||
uBlue-OS uses a sophisticated **akmods** system that serves as a caching layer for pre-built Fedora akmod RPMs.
|
||||
|
||||
#### **Key Components:**
|
||||
- **Pre-built RPMs**: uBlue-OS builds and caches kernel modules as RPM packages
|
||||
- **Kernel Flavor Support**: Supports multiple kernel flavors (standard, zen, bazzite, etc.)
|
||||
- **Module Categories**: Common, extra, nvidia, nvidia-open, zfs, and more
|
||||
- **Automated Builds**: CI/CD pipeline automatically rebuilds modules for new kernels
|
||||
|
||||
#### **Supported Modules:**
|
||||
```yaml
|
||||
# From uBlue-OS akmods images.yaml
|
||||
common:
|
||||
- v4l2loopback (virtual video devices)
|
||||
- gpd-fan-kmod (GPD Win Max fan control)
|
||||
- nct6687d (AMD B550 chipset support)
|
||||
- ryzen-smu (AMD Ryzen SMU access)
|
||||
- system76 (System76 laptop drivers)
|
||||
- zenergy (AMD energy monitoring)
|
||||
|
||||
nvidia:
|
||||
- nvidia (closed proprietary drivers)
|
||||
- nvidia-open (open source drivers)
|
||||
|
||||
zfs:
|
||||
- zfs (OpenZFS file system)
|
||||
```
|
||||
|
||||
#### **Build Process:**
|
||||
1. **Kernel Detection**: Automatically detects current kernel version
|
||||
2. **Module Building**: Builds modules for detected kernel
|
||||
3. **RPM Packaging**: Packages modules as RPMs
|
||||
4. **Distribution**: Distributes via container registry
|
||||
5. **Installation**: Installs via dnf/rpm-ostree
|
||||
|
||||
### 2. **Kernel Patching System** (Bazzite)
|
||||
|
||||
Bazzite uses a sophisticated kernel patching system with multiple patch categories:
|
||||
|
||||
#### **Kernel Variants:**
|
||||
- **Standard Kernel**: Fedora's default kernel
|
||||
- **Zen Kernel**: Optimized for desktop performance
|
||||
- **Bazzite Kernel**: Custom kernel with gaming optimizations
|
||||
|
||||
#### **Patch Categories:**
