ADB调试GPU方法

Android4.4 / Android5.1--Utgard

1. adb root
2. adb remount
3. adb shell
4. cd sys/modules/mali/paramters
5. cat gpufreq_table 查看GPU支持的所有频率
6. echo GPU频率 > gpufreq_min_limit；echo GPU频率 > gpufreq_max_limit​​

Android5.1 -- Midgard-自带DVFS

1. adb root
2. adb remount
3. adb shell
4. cd sys/modules/mali_kbase/paramters
5. cat gpu_freq_list 查看GPU支持的所有频率
6. echo GPU频率 > gpu_freq_min_limit；echo GPU频率 > gpu_freq_max_limit​​​

Android5.1 -- Midgard-Devfreq

1. adb root
2. adb remount
3. adb shell
4. cd /sys/devices/60000000.gpu/devfreq/60000000.gpu
5. cat available_frequencies 查看GPU支持的所有频率
6. echo GPU频率 > min_freq；echo GPU频率 > max_freq​​
