Major overhaul of power management system to address voltage-induced 4G
module hangs through intelligent, event-driven power regulation.
Key Features:
- Unified power regulation based on AC power + 4G modem state
- Event-driven AC detection via udev (power_supply subsystem)
- Three optimized power modes for different scenarios
- Automatic voltage monitoring with multi-method alerts
Power Modes:
- AC Connected: 2.4GHz (ondemand) - full performance
- Battery + 4G: 1.8GHz (powersave) - voltage monitoring enabled
- Battery Only: 2.0GHz (ondemand) - balanced performance
Technical Improvements:
- AC power state detection via udev events (not polling)
- Edge case handling (service starts with AC connected)
- Unified logging to /var/log/uconsole-power-regulator.log
- Upgrade path from old 4G Power Manager
- State tracking to avoid redundant regulator triggers
Components:
- uconsole-power-regulator.sh: Main power orchestrator
- uconsole-power-daemon.sh: Background state monitoring (5s interval)
- voltage-monitor.sh: Voltage checker (Battery + 4G only)
- voltage-alert-notify.sh: Multi-method alerts (desktop/audio/log/LED)
- voltage-monitor-control.sh: Monitor lifecycle controller
- 99-uconsole-power-regulator.rules: udev event triggers
- install-uconsole-power-regulator.sh: Installation + upgrade script
Documentation:
- Updated README.md with new system overview
- Created README_CN.md (Chinese translation)
- Updated TOOL-GUIDE.md with new architecture details
- Updated CLAUDE.md with unified system documentation
Breaking Changes:
- Replaces 4G Power Manager with unified regulator
- New service name: uconsole-power-regulator.service
- New log file: /var/log/uconsole-power-regulator.log
- Use upgrade script to migrate from old system
Installation:
- Fresh: sudo ./install-uconsole-power-regulator.sh install
- Upgrade: sudo ./install-uconsole-power-regulator.sh upgrade
- Uninstall: sudo ./install-uconsole-power-regulator.sh uninstall
