Run adb boot first, then set CPU/GPU frequency through below command:Īdb shell cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freqĪdb shell cat /sys/devices/system/cpu/cpu4/cpufreq/cpuinfo_cur_freq wrote: > Patch to enable Power management testcases in LTP to run on Power. Therefore, most modern operating systems support this feature. It’s available in most processors that were manufactured since 2003. This feature allows our CPUs to access physical memory sizes greater than 4 GB. Press "Ctrl" + "C" to exit Tinker Power Management anytime.
