@@ +# Performance Control Architecture for GameNative + +## Overview + +GameNative's performance control system provides CPU and GPU tuning capabilities for Android gaming devices. It supports multiple device types through an extensible driver architecture, including PServer-based devices (AYN Odin, Retroid Pocket) and Samsung Galaxy devices via the Samsung Performance SDK. The system allows users to adjust CPU governors, frequency scaling, and GPU performance levels to optimize game performance. Additionally, it features an **automatic performance tuning system** that uses PID controllers to dynamically adjust CPU/GPU settings based on target FPS and real-time utilization metrics, maintaining optimal performance while minimizing resource consumption. + +## Architecture + +### Core Components + +1. **PerformanceDriver** (Abstract Base Class) + -

After `PluviaApp.xEnvironment` is initialized + - `PowerManager.start()` is called + - **Profile Restoration**: + - Attempts to load saved profile from `PrefManager.powerControlProfile` + - If no saved profile, applies default Balanced profile from `driver.getDefaultProfile()` + - Applies profile settings to hardware via driver methods + - Driver-specific initialization occurs + +2. **Game Running** + - User can adjust performance settings via UI + - Each setting change calls the appropriate driver method + - **Automatic Profile Sync**: + - All setter methods update both driver and `PowerManager.currentProfile` + - Profile name changes to "Custom" when individual settings are modified + - Preset profile names are preserved when applying complete profiles + - PServerDriver: Writes to sysfs and sets files to 444 (read-only) + - SamsungPerformanceDriver: Calls `performanceManager.start(params)` with new settings + +3. **Game Environment Shutdown** (`PluviaApp.shutdownEnvironment()`) + - `PowerManager.stop()` is called + - **Profile Persistence**: + - Saves `currentProfile` to preferences for next session + - **Hardware Restoration**: + - PServerDriver: + 1. Resets CPU frequencies to full range (prevents slowness from Power Save) + 2. Resets GPU power levels to full range + 3. Restores CPU governor to first available governor + 4. Restores all modified sysfs files to 644 permissions + - SamsungPerformanceDriver: Calls `performanceManager.stop()` to stop all performance controls + +## Adding New Drivers + +To add support for a new device: + +1. Create a new driver class in `drivers/` folder extending `PerformanceDriver` +2.

This maintains target FPS while optimizing resource consumption. + +**Architecture:** + +*PerformanceAutoTuner:* +- Manages two independent PID controllers (CPU and GPU) +- Runs on background thread with 2-second tuning cycles +- Monitors: target FPS, current FPS, CPU usage, GPU usage +- Adjusts performance levels between 20-100% +- Maps performance percentages to actual hardware frequencies/levels + +*PidController:* +- Implements classic PID control algorithm +- **Proportional term (Kp=0.5)**: Immediate response to FPS error +- **Integral term (Ki=0.2)**: Eliminates steady-state error over time +- **Derivative term (Kd=0.1)**: Dampens oscillations for stability +- **Anti-windup protection**: Integral term clamped to ±50.0 +- **Output clamping**: Constrains adjustments to ±100.0 range + +**Tuning Logic:** + +*Reduce Performance (Conservative):* +``` +if (fpsError < 2.0 && usage < 70% && performance > 25%) { + performance -= 2.0% // Gradual reduction + reset PID controller +} +``` + +*Increase Performance (Aggressive):* +``` +if (fpsError > 5.0 || usage > 85%) { + adjustment = PID.calculate(targetFps, currentFps) + performance += adjustment * 0.3 // Damped increase +} +``` + +*Maintain Performance (Stable):* +``` +else { + reset PID controller // Clear integral/derivative state +} +``` + +**Integration Points:** + +1. **XServerScreen** → Sets `PowerManager.targetFps` from frame rate limiter +2. **PerformanceHudView** → Updates `PowerManager.currentFps`, `currentCpuUsage`, `currentGpuUsage` +3. **PowerManager** → Creates `PerformanceAutoTuner` with callbacks: + - `onCpuFrequencyChange(freq)` → Calls `setMinCpuValue()` and `setMaxCpuValue()` + - `onGpuLevelChange(level)` → Calls `setMinGpuPowerLevel()` and `setMaxGpuPowerLevel()` +4. **PowerProfile** → `enableAutoTuning` flag controls auto-tuner lifecycle + +**UI Behavior:** +- When auto-tuning is enabled, manual CPU/GPU controls are hidden +- Auto-tuning toggle is only shown when driver supports both CPU and GPU control +- Profile name changes to "Custom" when auto-tuning is toggled + +**Performance Characteristics:** + +*Startup Phase (0-10 seconds):* +- PID controllers initialize with zero state +- Performance starts at 50% baseline +- Rapid adjustments as integral term accumulates + +*Steady State (10+ seconds):* +- Small oscillations around target FPS (±2 FPS) +- Integral term compensates for steady-state error +- Derivative term prevents overshoot + +*Load Changes:* +- Scene complexity increase → FPS drops → PID increases performance +- Scene complexity decrease → FPS stable, usage drops → Gradual performance reduction +- Sudden FPS spike → Derivative term dampens response + +**Example Tuning Session (Simplified/Illustrative):** +``` +[0s] Target: 60 FPS, Current: 45 FPS, CPU usage: 50%, GPU usage: 50% + → Large FPS error (15.0 > 5.0 threshold) + → PID calculates adjustment, applies with decay factor (0.3) + → CPU perf: 50% → 52%, GPU perf: 50% → 52% + +[2s] Target: 60 FPS, Current: 54 FPS, CPU usage: 88%, GPU usage: 87% + → FPS error = 6.0 (> 5.0) OR CPU usage > 85% + → PID continues adjustment with integral accumulation + → CPU perf: 52% → 54%, GPU perf: 52% → 54% + +[4s] Target: 60 FPS, Current: 59 FPS, CPU usage: 78%, GPU usage: 75% + → FPS error = 1.0, usage between thresholds (70%-85%) + → Maintain current performance, reset PID + → CPU perf: 54% (unchanged), GPU perf: 54% (unchanged) + +[6s] Target: 60 FPS, Current: 60 FPS, CPU usage: 65%, GPU usage: 60% + → FPS stable (error < 2.0), usage below 70% threshold + → Gradual reduction (-2% step) + → CPU perf: 54% → 52%, GPU perf: 54% → 52% +``` +*Note: Actual PID calculations use Kp=0.5, Ki=0.2, Kd=0.1 with ADJUSTMENT_DECAY_FACTOR=0.3. +Enable verbose logging to see exact P/I/D terms and outputs.* + +**Logging:** +- Enable verbose logging via `PerformanceAutoTuner(enableLogging = true)` +- Logs PID
