EDIT3: this is NOT an overclock! Manually setting a scaling governor does not forcibly increase the intended frequency range of the CPU clock! Setting the scaling governor has more to do with performance management. In my case, setting it to "performance", it simply forces the cpu to always run at the maximum frequency as designed by the manufacturer. Further reading here and here. Thank you @nocteb@feddit.org for the reminder!

EDIT2: the tablet is rooted with Magisk ( https://topjohnwu.github.io/Magisk/install.html ) and Termux is running with superuser privileges granted through Magisk. The below command was issued after su - ing into a root shell. "performance" was echo ed into all available /sys/devices/system/cpu/cpufreq/.../scaling_governors, meaning, there are several subdirectories called policy[0...] in which the scaling_governor files reside.

EDIT: echo ing “performance” to /sys/devices/system/cpu/cpufreq/policy0/scaling_governor seems to have maxed out the cpu clockspeed! Now the tablet is snappy as hell! It’ll be interesting to see how battery drain and heat are affected by this. Thank you @tal@lemmy.today !

Say, by sending some value to something inside /sys/.../cpu or the likes. I have already aggressively debloated the tablet, but I like to experiment and I am not afraid to destroy the tablet since I bought it for 150 bucks at sale. Or pehaps there is some Magisk module that can do this?

The tablet is a Samsung Galaxy A9+.

You simply disabled the power management.

As dose most PC over clocking practically. It is just allowing chips to run at higher temps by removing the limitations on power designed to keep them managed.

Mobiles may be more strict. Due to battery life. But all over locking is considering the compremises and adjusting the priority.

With smart phones. The compromise is normally battery life rather then heat.

Desktops it's adding extra cooling and shortening the design lifetime of chips in exchange for Greater CPU cycles.

Which resulted in what I was aiming for. There are other available scaling governors that yield different frequencies.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
