I installed kernel 2.5.51 + the latest ACPI patch. This guy describes setting throttling with echo n >/proc/acpi/processor/CPU0/throttling. Below is my attempt of changing the active state, but it doesn't appear to do anything. [root@laptop CPU0]# pwd /proc/acpi/processor/CPU0 [root@laptop CPU0]# cat throttling state count: 16 active state: T0 states: *T0: 00% T1: 06% T2: 12% T3: 18% T4: 24% T5: 31% T6: 37% T7: 43% T8: 49% T9: 55% T10: 62% T11: 68% T12: 74% T13: 80% T14: 86% T15: 93% [root@laptop CPU0]# echo -n 9 > throttling [root@laptop CPU0]# cat throttling state count: 16 active state: T0 states: *T0: 00% T1: 06% T2: 12% T3: 18% T4: 24% T5: 31% T6: 37% T7: 43% T8: 49% T9: 55% T10: 62% T11: 68% T12: 74% T13: 80% T14: 86% T15: 93% ------------------------------------------------------- This sf.net email is sponsored by: With Great Power, Comes Great Responsibility Learn to use your power at OSDN's High Performance Computing Channel http://hpc.devchannel.org/
