 |
|
Hi!
I have a Fujitsu-siemens amilo xi-1546 notebook with intel centrino duo 2,16Ghz. After trying everything I still can't get any version of speedstep to work on my laptop and both cores work on their highest frequency no matter what I do. Does anyone know how to cope with it? Thanks.

I'm using cpufreqd on my T2300 @1.66GHz without any troubles.

| That's why I'm asking about people, who have >2Ghz Cpu - I know that T2300 works ok. |

works fine for me, do you have the right cpufreq kernel module and are you using the correct method of manipulating the frequency based on the cpufreq drivers you chose

| That's what I'm not so sure about - I follow gentoo-wiki but maybe I made a mistake somewhere. Could you tell me which modules do you use and all other related stuff? Thanks. |

you need Intel Enhanced Speedstep with sub associated options plus some governors, I recommend you set userspace to default and also compile in performance, powersave, and ondemand

Wojtek_, I have the same problem with my HP nc8430 Notebook. It has a Yonah T2500 (2Ghz).
With my previous BIOS cpufreq didn't work at all. Now it works but it is very buggy.
When selecting the performance governor it runs only at 1,66Ghz instead of 2.0Ghz.
I assume its a bug in the kernel or in the acpi tables. |

how are you actually trying to change the frequency in the userland?

Running cpufreqd gives:
| Code: | | * cpufreqd requires the kernel to be configured with CONFIG_CPU_FREQ |
And cpufrequtils gives:
| Code: | * Enabling ondemand cpufreq governor ...
[ !! ]unknown or unhandled CPU?

I definately had this exact problem for a few weeks it seemed when I first got my laptop. I just remember giving up on it and trying later in the future and it worked. There might be issues with the Core 2 Duos since they are so new. Maybe 2.6.19 will have fixes for them. However, when the time comes, your kernel config should look like this:
| : | [*] CPU Frequency scaling
Default CPUFreq governor (userspace) --->
<*> 'performance' governor
<*> 'powersave' governor
--- 'userspace' governor for userspace frequency scaling
<*> 'ondemand' cpufreq policy governor
<*> Intel Enhanced SpeedStep
[*] Use ACPI tables to decode valid frequency/voltage pairs
[*] Built-in tables for Banias CPUs
|
If it looks like this and it still dosen't work then look at the -mm sources brokenout patches for cpufreq updates that might apply to your machine

Hi guys,
i have HP nc6320 notebook (T2400 Centrino Duo) and i had the same problem as you. After many hours of googling etc, i found one possible solution :
in new HP BIOS F08 is bug in ACPI, reverting to F06 solve my problem
F06 (ACPI ok..)
| Code: |
CPI: RSDP (v000 HP ) @ 0x000f7d70

ACPI: DSDT (v001 HP nc6340 0x00010000 MSFT 0x0100000e) @ 0x00000000
..
..
..
ACPI: CPU0 (power states: C1[C1] C2[C2])
ACPI: Processor [CPU0] (supports 8 throttling states)
ACPI: CPU1 (power states: C1[C1] C2[C2])
ACPI: Processor [CPU1] (supports 8 throttling states)
|
F08 (bad one..)
| Code: |
ACPI: RSDP (v002 HP) @ 0x000f7f00
ACPI: XSDT (v001 HP 30AA 0x27070620 HP 0x00000001) @ 0x3f7e57b4

ACPI: DSDT (v001 HP nc6340 0x00010000 MSFT 0x0100000e) @ 0x00000000
..
..
..
ACPI: Processor [CPU0] (supports 8 throttling states)
ACPI: Processor [CPU1] (supports 8 throttling states)
|
so you can check it..

| Could you write the command that prints the information you provided? I've had three versions of bios and none of them made it possible to use speedstep with my cpu. |

Did you try 2.6.18-emission1 sources? Everything workes for me, suspend2 too.  ) This is probably the best kernel choice for laptops... Can you try it and post "dmesg | grep acpi" once again from this kernel?

There is something wrong with the kernel and my laptop working together - my kernel recognized most of the hardware incorrectly - all the chipsets were recognized as VIA and not intel etc. Speedstep doesn't work, sensors don't work and wireless works only after rebooting the machine. |
