I did some investigation and got it working, although it leads to some action items:
The file /etc/sysconfig/powersave/cpufreq allowed the specification of the kernel module to load. This was a fallback mechanism which did not work for me. Apparently, powersave no longer uses this item in this file (I cannot speak for any other items in this file), it says acpid does. So I check out acpid and acpid claims that *it* no longer supports loading this information (it *does* source the file and does nothing with the information therein, which is IMO a small bug). The responsibility falls on HAL.
Thus, item no. 1 is to document that the responsibility for loading the module is now HAL's job and neither powersave nor acpid's.
Yes, that's a bug. We were forced to move the loading of these modules to HAL at a late time in the process, so this variable didn't get removed although it's needless.
Item no. 2 is to remove the erroneous include line in acpid's init script. There may be other files that are sourced as well that are not used.
Ok, will have a look at that.
Item no. 3 is to have HAL get the parameter from a config file (/etc/sysconfig/powersve/cpufreq would be nice) but failing that to include p4-clockmod *which was not included in the list*. The static compilation of that list seems a little brittle to me but in any case the list is missing p4-clockmod (and p4_clockmod for the GREP line). Adding this information has allowed my powermanagement to work again.
No! Don't use p4_clockmod. It doesn't do frequency scaling but throttling. And throttling doesn't save you power, it only skips timer ticks making your system slow without any gain. p4_clockmod pretends to do scaling, but doesn't. That's the reason why it is not included in the list. In the initial comment you're writing that it saves you 26 minutes of battery life but I doubt that. Please come up with concrete figures if you are sure that's the case. Nevertheless, I will have a look at the remaining issues. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
