 Posted: Wed Apr 14, 2004 3:55 pm Post subject: cpufreq confusion on Mobile P4 |
 |
|
I have a Dell Inspiron 5150 with a Mobile Pentium 4 3.06 GHz processor (note that this is not a desktop Pentium 4, nor a Pentium 4-M - it's a Mobile Pentium 4). According to Windows and other sources, it has two states: 3.06 GHz and 1.6 GHz.
According to /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq, however, my max frequency is 1599960 kHz, or 1.6 GHz. This is gentoo-dev-sources-2.6.5.
Here's the pertinent .config parameters:
| Code: |
CONFIG_MPENTIUM4=y
#
# CPU Frequency scaling
#
CONFIG_CPU_FREQ=y
# CONFIG_CPU_FREQ_PROC_INTF 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=y
CONFIG_CPU_FREQ_GOV_USERSPACE=y
# CONFIG_CPU_FREQ_24_API is not set
CONFIG_CPU_FREQ_TABLE=y
#
# CPUFreq processor drivers
#
CONFIG_X86_ACPI_CPUFREQ=y
# CONFIG_X86_ACPI_CPUFREQ_PROC_INTF is not set
# CONFIG_X86_POWERNOW_K6 is not set
# CONFIG_X86_POWERNOW_K7 is not set
# CONFIG_X86_POWERNOW_K8 is not set
# CONFIG_X86_GX_SUSPMOD is not set
# CONFIG_X86_SPEEDSTEP_CENTRINO is not set
CONFIG_X86_SPEEDSTEP_ICH=y
# CONFIG_X86_SPEEDSTEP_SMI is not set
CONFIG_X86_P4_CLOCKMOD=y
CONFIG_X86_SPEEDSTEP_LIB=y
# CONFIG_X86_LONGRUN is not set
# CONFIG_X86_LONGHAUL is not set

Why can't the kernel see that my CPU is capable of 3.06 GHz? |

What is mentioned as cpuinfo_min_freq ? cat /proc/cpuinfo
Also, please enable debugging in arch/i386/kernel/cpu/cpufreq/speedstep-lib.c (uncomment //#DEFINE SPEEDSTEP_DEBUG or something like that), and send the relevant parts of dmesg to the maintainer of speedstep-ich and speedstep-lib (me) [linux at __nospam__ brodo dot de) |

I've been fiddling with cpufreqd, and amongst all my reboots and such, it looks like it's corrected itself. Bootup now says 3.06 GHz, and everything else reads as it should.
I'll reply to this again if something else comes up.
Thanks for the reply. |
