2.4.27 with acpi-20040326-24-stable-release


My problem concerns processor throttling and speedstep.
I've been using Aristo Prestige 570 with Intel(R) Pentium(R) M processor 1500MHz (celeron, centrino)
and recently i noticed that there is no /proc/cpufreq, and cat /proc/acpi/processor/CPU0/throttling returns <not supported>.
Am I to install some patches to gain control over processor's clock?
Would it be safe to apply the patches for frequency controlling on 2.4.27 compiled with acpi-20040326-24-stable.

Sorry, for my bad english.

dzien dobre,

Are you certain that the appropriate ACPI modules were selected in that kernel?

In Slackware 2.4.28 bareacpi config I have this select:
Code:
CONFIG_ACPI_PROCESSOR=y
this gives me 8 (0-7) cpu throttling states.

Also, is it possible that your bios does not support this? I had to upgrade to the newest bios in my Dell to get _any_ acpi functions.

I also noticed that there wasn't cpufreq menu in 2.4.27 make(LOL), so I decided to install cpufreq backport patch for 2.4 kernels (ftp.linux.org.uk/pub/linux/cpufreq/cpufreq-LINUX_2_4-20041227.tar.gz) but loading speedstep-centrino failed.... unresolved symbols.
I tried to patch it against pure 2.4.27 from kernel.org but it didn't help.
After installing new 2.6.10 kernel problem was solved.
I should have done it earlier.
