Hello, trying to get power management sorted on this notebook by following gentoo howto.
Trouble is that i can't find
| Code: |
/sys/devices/system/cpu/cpu0/cpufreq
|
found error that kernel does not support acpi but i have compiled acpi in:
| Code: |

Now when i had unbuntu on it powernowd did work, however there is no power saving settings in the bios what so ever and no sleep button.
What can be missing?
cheers

Hello, ok followed Fix Common ACPI Problems guide and fixed the one warning that was discovered, new dsdt in now compiled statically into kernel.
Problem is that i am still getting same problem on boot
| Code: |
powernow: Trying ACPI perflib
powernow: no support for ACPI processor found. Please recompile your kernel with ACPI processor
powernow: ACPI and legacy methods failed
|
| Code: |
ls /proc/acpi/
dsdt embedded_controller event fadt info power_resource
|
Here acpi kernel details
| Code: |
cat /usr/src/linux/.config | grep ACPI

Really not sure where to go now, want to use gentoo but can't have notebook without some power management

Hello, ok after 'fixing' acpi dstdt table powernow still complained:
| Code: |
powernow: PowerNOW! Technology present. Can scale: frequency and voltage.
powernow: No PST tables match this cpuid (0x7a0)
powernow: This is indicative of a broken BIOS.
powernow: Trying ACPI perflib
powernow: no support for ACPI processor found. Please recompile your kernel with ACPI
powernow: ACPI and legacy methods failed
|
After some research i found:
http://jos.nouwen.name/notebook/
which led me to
www.consultmatt.co.uk/linux/nx9005/powernow.php
The second site although not same notebook is same problem, that being that there is no pst table in powernow for the cpu in my notebook or more to the point the bios does not contain correct cpu ID so powernow does not find/recognise cpu and so fails.
Details of cpu can be found by emerging x86info and running:
See below for output.
To be honest this did not mean much to me, but the second sites problem was related to AMD mobile 2400 barton with ID 0x7a0, this is the same ID as my AMD mobile 2500 barton. There is a patch on the site to apply changes to powernow but it also contains other stuff not relevent to my notebook. Here is the relevent section:

Full patch http://www.consultmatt.co.uk/downloads/patches/kernel/2.6/2.6.1-all-in-1.patch
Now writing kernel patches is a little out of my skill range at moment so wonder if any one can help write one using x86info output below and details from patch above?
cheers

Update: I emailed the maintainer of powernow and he suggested trying mm-sources kernel, this cured powernow issue but introduced no related issues such as synaptic touchpad X setting preventing X loading, have emailed him again asking for relevent patch to try on gentoo-sources.

hello, ok tried applying the powernow patch in mm sources to gentoo-sources but got an error.
The patch can be found here:
ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.12-rc2/2.6.12-rc2-mm3/broken-out/
I did:
| Code: |
patch -p1 < powernow-k7recalibrate-cpu_khz.patch
|
then recompiled kernel but got error:
| Code: |
arch/i386/kernel/built-in.o(.init.text+0x540f): In function `powernow_cpu_init':
: undefined reference to `recalibrate_cpu_khz'
make: *** [.tmp_vmlinux1] Error 1
|
Any ideas what is amiss?
cheers
