DVFS
DVFS 的讨论
仅适用于Raspberry Pi 4 B型、Raspberry Pi 400 和计算模块 4。
Raspberry Pi 4 devices implement Dynamic Voltage and Frequency Scaling (DVFS).
This technique allows Raspberry Pi 4 devices to run at lower temperatures whilst still providing the same performance.
Raspberry Pi 4 设备实现动态电压和频率缩放 (DVFS)。
该技术允许 Raspberry Pi 4 设备在较低温度下运行，同时仍提供相同的性能。
dvfs=1 => allow undervoltage / 允许欠压
dvfs=2 => fixed voltage for default operating frequencies
dvfs=3 => scale voltage up on demand for over clocking (default). If over_voltage is specified in config.txt then dynamic voltage scaling is disabled causing the system to revert to dvfs=2.
