Description of problem: I have a HP DL360-G5 server with a Xeon 5110 CPU. Would like to use cpuspeed, snag I am not getting any drivers loaded. Note machine is installed with the x86_64 kernel so I do not think it relates in any way to the i586, i686 issue that has made it in to the Frequent problems catagory. Mail symptom seems to be that the following file does not exists. ls /sys/devices/system/cpu/cpu*/cpufreq/scaling_driver ls: /sys/devices/system/cpu/cpu*/cpufreq/scaling_driver: No such file or directory my under standing from serching with Google is that the Xeon 5110 should use the speedstep-centrino module Version-Release number of selected component (if applicable): Have tried with the following kernels kernel-2.6.18-1.2798.fc6.x86_64.rpm kernel-2.6.19-1.2895.fc6.x86_64.rpm kernel-2.6.19-1.2911.6.4.fc6.x86_64.rpm kernel-2.6.19-1.2911.6.5.fc6.x86_64.rpm kernel-2.6.19-1.2911.fc6.x86_64.rpm kernel-2.6.20-1.2925.fc6.x86_64.rpm How reproducible: Every Time Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info: I tried Building the variouse cpufreq options as modules against the kernel-2.6.19-1.2911.6.5.fc6.src.rpm The modules build but all give a "no such device" error when I try to load them with modprobe. find /sys/devices/system/cpu/cpu* -print /sys/devices/system/cpu/cpu0 /sys/devices/system/cpu/cpu0/topology /sys/devices/system/cpu/cpu0/topology/core_siblings /sys/devices/system/cpu/cpu0/topology/thread_siblings /sys/devices/system/cpu/cpu0/topology/core_id /sys/devices/system/cpu/cpu0/topology/physical_package_id /sys/devices/system/cpu/cpu0/cache /sys/devices/system/cpu/cpu0/cache/index2 /sys/devices/system/cpu/cpu0/cache/index2/shared_cpu_map /sys/devices/system/cpu/cpu0/cache/index2/size /sys/devices/system/cpu/cpu0/cache/index2/number_of_sets /sys/devices/system/cpu/cpu0/cache/index2/ways_of_associativity /sys/devices/system/cpu/cpu0/cache/index2/physical_line_partition /sys/devices/system/cpu/cpu0/cache/index2/coherency_line_size /sys/devices/system/cpu/cpu0/cache/index2/level /sys/devices/system/cpu/cpu0/cache/index2/type /sys/devices/system/cpu/cpu0/cache/index1 /sys/devices/system/cpu/cpu0/cache/index1/shared_cpu_map /sys/devices/system/cpu/cpu0/cache/index1/size /sys/devices/system/cpu/cpu0/cache/index1/number_of_sets /sys/devices/system/cpu/cpu0/cache/index1/ways_of_associativity /sys/devices/system/cpu/cpu0/cache/index1/physical_line_partition /sys/devices/system/cpu/cpu0/cache/index1/coherency_line_size /sys/devices/system/cpu/cpu0/cache/index1/level /sys/devices/system/cpu/cpu0/cache/index1/type /sys/devices/system/cpu/cpu0/cache/index0 /sys/devices/system/cpu/cpu0/cache/index0/shared_cpu_map /sys/devices/system/cpu/cpu0/cache/index0/size /sys/devices/system/cpu/cpu0/cache/index0/number_of_sets /sys/devices/system/cpu/cpu0/cache/index0/ways_of_associativity /sys/devices/system/cpu/cpu0/cache/index0/physical_line_partition /sys/devices/system/cpu/cpu0/cache/index0/coherency_line_size /sys/devices/system/cpu/cpu0/cache/index0/level /sys/devices/system/cpu/cpu0/cache/index0/type /sys/devices/system/cpu/cpu0/thermal_throttle /sys/devices/system/cpu/cpu0/thermal_throttle/count /sys/devices/system/cpu/cpu0/crash_notes /sys/devices/system/cpu/cpu1 /sys/devices/system/cpu/cpu1/topology /sys/devices/system/cpu/cpu1/topology/core_siblings /sys/devices/system/cpu/cpu1/topology/thread_siblings /sys/devices/system/cpu/cpu1/topology/core_id /sys/devices/system/cpu/cpu1/topology/physical_package_id /sys/devices/system/cpu/cpu1/cache /sys/devices/system/cpu/cpu1/cache/index2 /sys/devices/system/cpu/cpu1/cache/index2/shared_cpu_map /sys/devices/system/cpu/cpu1/cache/index2/size /sys/devices/system/cpu/cpu1/cache/index2/number_of_sets /sys/devices/system/cpu/cpu1/cache/index2/ways_of_associativity /sys/devices/system/cpu/cpu1/cache/index2/physical_line_partition /sys/devices/system/cpu/cpu1/cache/index2/coherency_line_size /sys/devices/system/cpu/cpu1/cache/index2/level /sys/devices/system/cpu/cpu1/cache/index2/type /sys/devices/system/cpu/cpu1/cache/index1 /sys/devices/system/cpu/cpu1/cache/index1/shared_cpu_map /sys/devices/system/cpu/cpu1/cache/index1/size /sys/devices/system/cpu/cpu1/cache/index1/number_of_sets /sys/devices/system/cpu/cpu1/cache/index1/ways_of_associativity /sys/devices/system/cpu/cpu1/cache/index1/physical_line_partition /sys/devices/system/cpu/cpu1/cache/index1/coherency_line_size /sys/devices/system/cpu/cpu1/cache/index1/level /sys/devices/system/cpu/cpu1/cache/index1/type /sys/devices/system/cpu/cpu1/cache/index0 /sys/devices/system/cpu/cpu1/cache/index0/shared_cpu_map /sys/devices/system/cpu/cpu1/cache/index0/size /sys/devices/system/cpu/cpu1/cache/index0/number_of_sets /sys/devices/system/cpu/cpu1/cache/index0/ways_of_associativity /sys/devices/system/cpu/cpu1/cache/index0/physical_line_partition /sys/devices/system/cpu/cpu1/cache/index0/coherency_line_size /sys/devices/system/cpu/cpu1/cache/index0/level /sys/devices/system/cpu/cpu1/cache/index0/type /sys/devices/system/cpu/cpu1/thermal_throttle /sys/devices/system/cpu/cpu1/thermal_throttle/count /sys/devices/system/cpu/cpu1/crash_notes /sys/devices/system/cpu/cpu1/online
You probably need to enable Speedstep in your BIOS setup. I have: model name : Intel(R) Xeon(R) CPU 5120 @ 1.86GHz $ pwd ; ls | sort /sys/devices/system/cpu/cpu0/cpufreq affected_cpus cpuinfo_cur_freq cpuinfo_max_freq cpuinfo_min_freq ondemand scaling_available_frequencies scaling_available_governors scaling_cur_freq scaling_driver scaling_governor scaling_max_freq scaling_min_freq

Selecting the first option :- System Options and then the last :- Power Regulator for ProLiant Yealds 4 options :- HP Dynamic Power Saving Mode HP Static Low Power Mode HP Static High Performance Mode OS Controled Mode { the Manual shows the 4th option as "disabled"} I have tried all 4 settings. In all cases Power consumption is between 205 and 209 W, independent of CPU load. With none of the settings do I get the /sys/devices/system/cpu/cpu0/cpufreq directory.
I'd suggest seeing if there's a bios update for that machine. A number of other HP systems recently got bios updates that fixed non-functional cpu scaling support. Of course, those were primarily laptops with Core 1/2 Duo processors, but one can hope...
(This is a mass-update to all current FC6 kernel bugs in NEW state) Hello, I'm reviewing this bug list as part of the kernel bug triage project, an attempt to isolate current bugs in the Fedora kernel. http://fedoraproject.org/wiki/KernelBugTriage I am CC'ing myself to this bug, however this version of Fedora is no longer maintained. Please attempt to reproduce this bug with a current version of Fedora (presently Fedora 8). If the bug no longer exists, please close the bug or I'll do so in a few days if there is no further information lodged. Thanks for using Fedora!
Per the previous comment in this bug, I am closing it as INSUFFICIENT_DATA, since no information has been lodged for over 30 days. Please re-open this bug or file a new one if you can provide the requested data, and thanks for filing the original report!
