I think it's good. What we need, at least in my opinion, is to make this page a bit more pedagogic. As for now I see users becoming confused as to what module(s) they need and how to set it up. A user in the forum misunderstood this wiki page and struggled because he/she did add practically all possible modules to rc.conf.

Hello,

I'd like to point out that there's an issue with the p4-clockmod driver combined with the ondemand governor,

as seen here:

+
In short, the advice given in this wiki article isn't actually working(anymore) and for a newcomer(like me) there isn't really
+
a working substitute(as in re-compiling the kernel and modules).
+
 
+
== acpid ==
+
 
+
I found that acpi events were not processed until I installed acpid and added that to the daemon list (I removed laptop-mode).

+
== Move to [[cpufrequtils]] ==
+
 
+
I'm not sure why this page that specifically covers the cpufrequtils package was moved from cpufrequtils to this more generic title. The article title should match the package/utility described within, in my opinion. -- [[User:Pointone|pointone]] 18:41, 25 January 2011 (EST)

:The page contains incorrect information right now - it confuses the kernel's cpufreq with the userspace cpufrequtils package. All of the stuff on the page about drivers/modules, governors, /sys, etc. is independent of cpufreq'''utils'''. cpufrequtils provides a daemon script to set the governors and 3 userspace utilities, which offer similar functionality to the /sys filesystem and powertop. The two methods on the page for using laptop-mode-tools and acpid to set the governor are completely independent of cpufrequtils. I moved the page here after someone resurrected the old version that got merged into this article, because they were right that cpufrequtils != cpufreq, but there was also no reason to have 2 pages describing the same stuff.

CPU frequency driver

"Note: As of kernel 3.4; the native cpu module is loaded automatically"

I tested today in my netbook with Atom 330 with kernel 3.7 [testing]. the autoload module not working (after edit modules-load.d and reboot)

this still workinkg?
