 Posted: Thu Mar 30, 2006 9:41 pm Post subject: welche Kernelkomponenten für Centrino CPU |
 |
|
Hallo,
ich bekomme das Powermanagement meines Notebooks Toshiba M100 mit Centrino CPU einfach nicht zum Laufen.
Der Prozessor arbeitet stets nur mit 600MHz und nicht mit den maximal verfügbaren 1200MHz.
| Code: | P3490CT ~ # cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6

Hier scheint ja alles in Ordnung zu sein.
| Code: | P3490CT ~ # cpufreq-info
cpufrequtils 0.4: cpufreq-info (C) Dominik Brodowski 2004
Report errors and bugs to linux@brodo.de, please.
analyzing CPU 0:
driver: p4-clockmod
CPUs which need to switch frequency at the same time: 0
hardware limits: 75.0 MHz - 600 MHz
available frequency steps: 75.0 MHz, 150 MHz, 225 MHz, 300 MHz, 375 MHz, 450 MHz, 525 MHz, 600 MHz
available cpufreq governors: performance
current policy: frequency should be within 600 MHz and 600 MHz.
The governor "performance" may decide which speed to use
within this range.
current CPU frequency is 600 MHz (asserted by call to hardware).

cpufreq-info scheint der Meinung zu sein, dass der Prozessor maximal 600MHz kann.

Es scheint etwas mit den Kernelmodulen falsch zu sein.

Nach den Meldungen von dmesg würde ich sagen, dass die Komponente "Intel Pentium 4 clock modulation" falsch ist, jedoch funktioniert cpufreq-info ohne diese überhaupt nicht. Ich weiß leider nicht, welche anstelle dieser aktiviert werden soll (leider steht nirgendwo centrino dran). |

Hast du den governor in /etc/conf.d/cpufrequtils gesetzt?
Ich verwende hier den ondemand governor, der funktioniert bestens. Kannst den ja mal aktivieren.
| Code: | | < > 'ondemand' cpufreq policy governor |

In /etc/conf.d/cpufrequtils steht:

# Which governor to use. Must be one of the governors listed in:
# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors
#
GOVERNOR="ondemand"
M100 / #
|
Die Kernelkomponente:
| Code: | | <*> 'ondemand' cpufreq policy governor |
habe ich jetzt auch aktiviert. Jedoch bringt das keine Veränderung der Ausgaben für cpufreq-info und dmesg.
Der Prozessor arbeitet nach wie vor nur bei 600MHz. |

Hmm, die verfügbaren governor sollten sich dann eigentlich ändern.
| Code: | | available cpufreq governors: ondemand, userspace |
Hast du auch den default governor auf "userspace" gesetzt?
| Code: | [*] CPU frequency translation statistics details
Default CPUFreq governor (userspace) ---> |
"Intel Pentium 4 clock modulation" kannst du übrigens deaktivieren, ist AFAIK nur für XEONs. |

Stimmt, die verfügbaren governor haben sich geändert. Das habe ich glatt übersehen.
Ich habe jetzt den default governor auf userspace geändert.

Was mir ja jetzt erst auffällt, da wird der falsche Treiber verwendet
| Code: | | driver: p4-clockmod |
Da sollte eigentlich centrino stehen. Falls noch nicht geschehen, deaktiviere "Intel Pentium 4 clock modulation".
Hier mal alles was ich unter CPU Frequency scaling aktiviert habe:
| Code: | [*] CPU Frequency scaling
<*> CPU frequency translation statistics
[*] CPU frequency translation statistics details
Default CPUFreq governor (userspace) --->
<*> 'ondemand' cpufreq policy governor
<M> ACPI Processor P-States driver
<*> Intel Enhanced SpeedStep
[*] Use ACPI tables to decode valid frequency/voltage pairs
[*] Built-in tables for Banias CPUs |

Also mit der Konfiguration:
| Code: | [*] CPU Frequency scaling
<*> CPU frequency translation statistics
[*] CPU frequency translation statistics details
Default CPUFreq governor (userspace) --->
<*> 'ondemand' cpufreq policy governor
<*> ACPI Processor P-States driver
<*> Intel Enhanced SpeedStep
[*] Use ACPI tables to decode valid frequency/voltage pairs
[*] Built-in tables for Banias CPUs
< > Intel Pentium 4 clock modulation |
erhalte ich die Fehlermeldung:
| Code: | M100 / # dmesg

no or unknown cpufreq driver is active on this CPU
M100 / # |
Gibt es noch irgendwelche anderen Optionen, die man einstellen muss?
Bei Processor type and features habe ich
| Code: | | (X) Pentium-4/Celeron(P4-based)/Pentium-4 M/Xeon |
ausgewählt. Spielt das hier vielleicht auch eine Rolle? |

Allerdings! Da hast du schlicht die falsche CPU ausgewählt, so ist es richtig:

Brauchst du nicht, einfach mal weg lassen. Dem Kernel kannst du auch ueber das Sys-Interface oder ueber Desktop-Applets sagen was du so willst, damit koenntest du eher Feinsteuerung betreiben oder so.
Damit hast du zumindest eine Fehlerquelle weniger, an den cpufrequtils muss es nicht liegen.

Ich glaube nicht, dass das Problem an den cpufrequtils liegt. Ich bin mir ziemlich sicher, dass es an den Kernel-Modulen liegt, da beim Laden des Kernels die ersten Fehlermeldungen angezeigt werden (siehe die Ausgabe von dmesg oben).
