NOTE
for those using kernel manger like hktweaks, mtweaks, etc:
if you have been playing around with the cpu page and turning on and off the cpu cores before
AND
if you have saved the settings in profile, please check your profile settings in those app by clicking on the menu in the profile page and select profile details to see if you are actually running with one or more cpu cores offline
if you find in the details something like below, then you have turned off one or more cores, ie you are not running with all cores online! look for a line looks like:
echo 0 > /sys/devices/xxxxxxxxxx/cpu/cpu7/online
0 means off, so the above command will turn off core 4 in m3 (cpu 0-3 refers to the little cores, 4-7 refers to the big cores)
i have checked by command these app will actually turn off the cpu core but just do not show them properly in the app, and have problems in turning the cores back online
remedies for normal users:
- disable run at boot option and reboot (to let all cores online again)
- re-apply the settings you have made before but DON'T touch the online/offline toggles
- save as a new profile
- check the profile details again and make sure you didnt bring any of them offline before applying auto start option
OR (just found out last nite)
- click one the profile's menu, choose edit
- select those unwanted item one by one in the list, and delete
good luck!
