Why DevTerm A06 have 2 offline CPU by default

[OzelotVanilla]

I just have my second-hand DevTerm A06, and I found in htop, only four cores are running.

I used lscpu and found there are 2 offline CPU 4 and 5, and I can manually open it by chcpu -e 4,5.

I am wondering why these CPU are disabled by default. I have installed clean ClockworkOS v0.2, so it is not the configuation for its first owner that causes this situation.

Or if the CPU is managed by some tools of DevTerm ? If some conditions are met, the manager will automatically close/open CPU ?

They’re disabled by default. I suppose to maximize thermal cooling and battery life? to utilise all 4, you need the governor for it (already included with the stock OS image) but hey, sounds like you need the gearbox GUI version:

Gearbox GUI program for the Devterm

Hi! I wanted to have some kind of a widget like the wifi or sound button on the taskbar to change the cores, so I made one myself! [image] I have been having fun making this and even if I made it with tech I am comfortable with, still learned alot! It features GUI widgets that let you set each core frequency and governors. It also has presets which for now are the ones that come with the original script, and anyone could add more (Although thats still undocumented) [image] [dt] I created …

The link above is a step up from clockworkpi’s terminal-only gearbox and should’ve been included in future image updates of the OS from now on really.

While you’re at it, tweak the fan speed too:

for a06 EDIT /usr/local/bin/temp_fan_daemon_a06.py MAX_TEMP=50000 50000 is 50 deg and don’t install rpi package on A06 try sudo apt update && apt install -y devterm-fan-daemon-cpi-a06

lemme just say that I apologize on behalf of the community here that the information regarding the device is all over the place. A little bit of search could go a long way, so I hope the two linked above could point you in the right direction. Do stay around and have fun with your devterm!
