cpufreq是一个动态调整cpu频率的模块,系统启动时生成一个文件夹/sys/devices/system/cpu/cpu0/cpufreq/,里面有几个文件,其中scaling_min_freq代表最低频率,scaling_max_freq代表最高频率,scalin_governor代表cpu频率调整模式,用它来控制CPU频率。 cd /sys/devices/system/cpu/cpu0/cpufreq/affected_cpus bios_limi...
当policy的governor设置为“performance”时,还有每当scaling_max_freq或scaling_min_freq策略限制发生变化时,请求进行一次。 powersave 当附加到policy对象时,此governor会在“scaling_min_freq”策略限制内为该策略请求最低频率。 当policy的governor设置为powersave时,还有每当之后scaling_max_freq或scaling_min_freq策略...

echo <max freq | other freq> > /sys/class/kgsl/kgsl-3d0/gpuclk 参数设置解释：1、echo 1 > force_clk_on是设置KGSL_PWRFLAGS_CLK_ON这个power_flags。使用echo freq > gpuclk时，是通过kgsl_pwrctrl_pwrlevel_change设置频率，它会判断KGSL_PWRFLAGS_CLK_ON这个power_flags，如果没有这个...

我想在安卓设备上的/sys/ scaling_max_freq /system/cpu/cpu0/cpufreq/文件中更改一个名为scaling_max_freq的值。在另一篇文章中,我读到我可以通过echo命令这样做: echo 255 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq ,其中"255“是我想要放在文件中的值。,我如何通过java继承它? 浏览...
