intel_pstate not working. CPU frequency fixed at 800MHz.
I've tried to modify frequency using "cpufreq-set" and also by directly writing to files in "/sys/devices/system/cpu/cpu0/cpufreq/*" to no success.
I tried different versions of kernel, it started working on 4.17.0 but stopped working soon. These are the versions I tested.
5.2.3 - Not Working
5.1.0 - Not Working
4.19.60 - Not Working
4.18.20 - Not Working
4.17.19 - Not Working
4.17.10 - Not Working
4.17.5 - Not Working
4.17.3 - Working
4.17.2 - Working
4.17.1 - Working
4.17.0 - Working
4.16.18 - Not Working
4.15.0 - Not Working
Please let me know if anything else is needed.
thanks
