I think not. /sys is not mounted and the termux user is a fake root with limited access.

Thanks! I have no idea how Android works really, so I’ll take this opportunity to learn how filesystems are mounted on this bad boi.

Although, following another commenter’s advice, I did manage to max out the cpu frequency reported by /sys/devices/system/cpu/policy0/cpuinfo_cur_freq but echo ing performance to scaling_governor.

Kinda. Kinda not. If you rooted the tablet, you can just run su in termux to get elevated out of termux entirely and into Android’s root shell. Then fucking about with values may get you an overclock, however it’s possible no options will exist at all, since it would depend on the kernel version and CPU.

Thanks! I didn’t have my hopes up, but echoing “performance” to the scaling_governor seems to have maxed out the cpu frequency as reported by cpuinfo_cur_freq.

If you haven’t already, I’d see if you could put lineageos on it instead of Samsung’s crap.
