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+.
Yeah could be. There’s some latency for sure, the question is whether it’s noticeable. Definitely hard to tell subjectively, and as far as I know, also hard to measure without special equipment. I just think it’s probably not worth it to use the performance governor, even for (say) a laptop connected to a power supply, just because of the extra heat, fan noise, or the potentially earlier throttling. But I guess you have to judge that for yourself.
