ACPI Throttling in Ubuntu
- by Evan
I'm looking to throttle my cpu through the ACPI. I've read up on it, but I keep receiving permission denied statements. I have 8 available throttling states. Here are the outcomes of my atttempts:
evan@evan-laptop:/proc/acpi/processor/CPU0$ echo 3 /proc/acpi/processor/CPU0/throttling
bash: /proc/acpi/processor/CPU0/throttling: Permission denied
evan@evan-laptop:/proc/acpi/processor/CPU0$ sudo echo 3 /proc/acpi/processor/CPU0/throttling
bash: /proc/acpi/processor/CPU0/throttling: Permission denied
EDIT: For reference, I am running Ubuntu Karmic with Intel Core Duo T2500 with ACPI enabled
