The whitepaper we refer to is: Configuring and Tuning HP ProLiant Servers for Low-Latency Applications The main takeaway is to run with the "Maximum Performance" profile. You can also enter a special BIOS menu using CTRL-A from the RBSU screen. This allows you to toggle the "Processor Power and Utilization Monitoring" flag off. The recommended SLES (and RHEL) OS-level settings are also contained within the document. So I'm curious as to why you're interested in manipulating CPU frequency from the OS. I'm assuming you'd want the highest CPU clock speed during the periods of trading activity, so when would you require OS control? (We actually disable all OS CPU speed control) It looks like you're us

I know, there are a lot of threads about CPU frequency scaling, I've read all I found. Here's the problem: When I try to use CPU frequency scaling (ie. the gnome applet), I get an error message "CPU frequency scaling unsupported". The hardware is a HP EliteBook 8560w, with Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz processor. I already updated bios to the latest version (68SVD Ver. F.22) but it didn't help. The log says "[Firmware Bug]: BIOS needs update for CPU frequency support". Does anyone know how to solve this? Is tweaking the DSDT an option? If so, how is this done? Thanks a lot in advance. [update:] Experimenting with the kernel modules shows some new error messages: * using acpi-cpufreq.ko shows "[Firmware Bug]: ACPI: Invalid BIOS_PSS frequency: 0x80000000 MHz" in the log and "Input/output error" on the terminal, * using p4-clockmod.ko gives "[Firmware Bug]: ACPI: BIOS_OSI(Linux) query ign

Have you installed the YaST power utility? Open YaST / Software / Software Management, search on power and install yast2-power-management. Then, a new system item will be added. You must restart YaST to see it. Also, go into System Services (Runlevel), enable pm-profiler, start it and accept the new setup. Then, you can run YaST / System / Power Managem and select Low Latency Computing which should run your CPU at full speed.

Do I understand it correctly that the system freezes _after_ modprobing cpufreq_acpi_pdump fails??? The -EIO result itself isn't strange, it means the call to acpi_processor_register_performance() failed which happens on several systems.

The guys who own this machine have about ten of those (IBM R40e - Mobile Celeron). Tested on three machines and it was the same problem on each.
