cpufreq-info一查,内核加载的是intel_pstate驱动,而不是原来的cpufreq的那个驱动,现在cpu最大频率可以达到3ghz。虽然它指明cpu的最小频率是800mhz,但实际上系统运行过程中,cpu的最小频率一直维持在2ghz。听说kernel 3.14版本更新的intel_pstate驱动,不过这次我不会再升级内核了。在升级内核的过程中,我参考了...
current CPU frequency is 792 MHz (asserted by call to hardware). cpufreq stats: 792 MHz:71.84%, 996 MHz:11.36%, 1.20 GHz:16.81% (22) Where as in the same device shows different value in 4.1.15 kernel version. root@imx7dsabresd:~# cpufreq-info cpufrequtils 008: cpufreq-info (C...

One of our in-house tools needs to check/set the CPU governor usually found at: /sys/devices/system/cpu/cpu<N>/cpufreq/scaling_governor, where <N> is the core number. However these files do not exist. Looking at cpufreq-info: $ cpufreq-info cpufrequtils 008: cpufreq-info (C) Dom...
