APM Driver (apmdrv)

Purpose:

• Dynamic CPU frequency control based on real-time load using a sliding window and jiffies-based idle measurement.

Features

• Controls CPU frequency via mpm driver
• Uses a sliding window (8 samples) for load smoothing
• Jiffies-based idle accounting (no high-resolution timers needed)
• Thresholds: 70% (increase), 30% (decrease) with hysteresis
• Minimum residency: 250 ms per frequency
• Default initial frequency: 133 MHz (index 0) Target Platform Optimized for Motorola iLJ-based smartphones

Target Platform

• Motorola mobile phones iLJ platform based (i9, etc.)
