Eelco Dolstra 685a901597 Fix description of powerManagement.cpuFreqGovernor 2013-01-24 13:55:59 +01:00
Eelco Dolstra e194d41b9c cpufreq: Don't complain if a CPU doesn't support the desired governor 2012-08-23 12:12:25 -04:00
Eelco Dolstra 9e5bbee2b1 Make cpufreq a service instead of a task 
Otherwise it will be restarted by switch-to-configuration even when it
hasn't changed.

Eelco Dolstra cc41bce79d * Prevent merging of some options. P.S. maybe string options 
should be "uniq" by default.

Eelco Dolstra cf36b3db80 * If power management is enabled, set the governor to ‘ondemand’ by 
default.  See
  
    http://www.codon.org.uk/~mjg59/power/good_practices.html
    
  for the reasoning.  (Basically, the ‘performance’ and ‘powersave’
  governors don't actually provide extra performance or power savings
  in most cases.)

  It used to be that desktop environments like KDE were able to set
  the governor through HAL (e.g. KDE could be configured to switch to
  the powersave governor when the user unplugs his laptop).  However,
  this is no longer the case with upower — it is now expected that
  everybody uses the ondemand governor.  See

    http://old.nabble.com/-PATCH--powerdevil-remove-cpufreq.patch-td27815354.html

* Rename ‘cpuFreqGovernor’ to ‘powerManagement.cpuFreqGovernor’.

* Include cpufreq-utils in the system path if a governor is set, since
  we depend on it anyway.
