Hope acpi-devel list readers know something more to help me ou= t. =20 ----------------8<--------------- Hi, I've been using ACPI patches to my 2.4.20 kernel for a while since it's the only way to get my laptop's IRQ table in order during boot. So far so happy! (LT: Acer TM 621) =20 Recently I started experimenting with the 'write' interface and tried to get the performance of my coppermine PIII 1G to switch from 1G to 733MHz or vise versa using echo -n 1 > /proc/acpi/CPU0/performance =20 But both 'cat'ing performance to see what happened and running bogomips show my processor is still running @ 1GHz. It is also the other way roun= d. Once booted at 733MHz (because of absence of AC adapter) it cannot be fo= rced into 1G, even with AC attached. =20 Info tells me performance management is available: cat /proc/acpi/processor/CPU0/info: processor id: 0 acpi id: 1 bus mastering control: yes power management: yes throttling control: no performance management: yes limit interface: yes =20 cat /proc/acpi/processor/CPU0/performance: state count: 2 active state: P0 states: *P0: 1000 MHz, 20000 mW, 500 uS P1: 733 MHz, 10000 mW, 500 uS =20 Am I doing something wrong? Forgot to compile in something? =20 Further I echoed 1 to /proc/acpi/sleep. My laptop perfectly blanked the screen, but was unwakeable after. The screen comes back, but no reaction to the keyboard in any way. Again: Am I doing something wrong? =20 If there's anything I can do to help/test please let me know. =20 Martin van Es ------------------------------------------------------- This SF.NET email is sponsored by: FREE SSL Guide from Thawte are you planning your Web Server Security?
