 |
|
I'm working with a 2.6.20-gentoo-r8 kernel on a DELL D820. Since I bought it a year ago, I never figured out how to have the power management working because of the cpufreqd complaining:
| Code: |
> /etc/init.d/cpufreqd start
* cpufreqd requires the kernel to be configured with CONFIG_CPU_FREQ
|
whereas the CONFIG_CPU_FREQ is actually set:
| Code: |
> grep CONFIG_CPU /usr/src/linux/.config
CONFIG_CPUSETS=y
CONFIG_CPU_FREQ=y
CONFIG_CPU_FREQ_TABLE=m
# CONFIG_CPU_FREQ_DEBUG is not set
CONFIG_CPU_FREQ_STAT=m
# CONFIG_CPU_FREQ_STAT_DETAILS is not set
CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y
# CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE is not set
CONFIG_CPU_FREQ_GOV_PERFORMANCE=y
CONFIG_CPU_FREQ_GOV_POWERSAVE=m
CONFIG_CPU_FREQ_GOV_USERSPACE=m
CONFIG_CPU_FREQ_GOV_ONDEMAND=m
CONFIG_CPU_FREQ_GOV_CONSERVATIVE=m
|
On the other hand, the cpufreq-info command says that "there is no known driver for cpufreq"
| Code: |
> cpufreq-info
cpufrequtils 002: cpufreq-info (C) Dominik Brodowski 2004-2006
Veuillez rapportez les erreurs et les bogues à linux@brodo.de, s'il vous plait.

There has to be something missing in my kernel configuration. Could anybody make a suggestion?

| you need to enable in kernel config a cpufreq driver, not only the governors! read their helps to find the right one for your cpu |

I clumsily tried the following setting in kernel configuration an it worked:
| Code: |
[*] CPU Frequency scaling
[ ] Enable CPUfreq debugging
<*> CPU frequency translation statistics
[ ] CPU frequency translation statistics details
Default CPUFreq governor (performance) --->
--- 'performance' governor
<*> 'powersave' governor
<*> 'userspace' governor for userspace frequency scaling
<*> 'ondemand' cpufreq policy governor
<*> 'conservative' cpufreq governor
--- CPUFreq processor drivers
<M> ACPI Processor P-States driver
< > AMD Mobile K6-2/K6-3 PowerNow!
< > AMD Mobile Athlon/Duron PowerNow!
< > AMD Opteron/Athlon64 PowerNow!x
< > Cyrix MediaGX/NatSemi Geode Suspend Modulation
<*> Intel Enhanced SpeedStep
--- Built-in tables for Banias CPUs
<*> Intel Speedstep on ICH-M chipsets (ioport interface)
<*> Intel SpeedStep on 440BX/ZX/MX chipsets (SMI interface)
<*> Intel Pentium 4 clock modulation
< > nVidia nForce2 FSB changing
< > Transmeta LongRun
< > VIA Cyrix III Longhaul
--- shared options
[ ] /proc/acpi/processor/../performance interface (deprecated)
[ ] Relaxed speedstep capability checks
