ACPI (Advanced Configuration and Power Interface)
-------------------------------------------------
http://www.acpi.info[ACPI] je otvoreny standard vzajomnej komunikacie
hardveru, ktory na rozdiel od `APM` pracuje na urovni operacneho systemu
(a nie BIOSu), z coho prameni jeho vyssia flexibilita.

ACPI4Linux
~~~~~~~~~~
http://acpi.sourceforge.net[ACPI For Linux] je konkretna implementacia
standardu ACPI pre Linux. V aktualnych verziach sa nachadza priamo
v hlavnej verzii Linuxu, takze nie je potrebne rucne aplikovat zaplaty.

Potrebne je mat v Linuxe zapnute volby `CONFIG_PM`, `CONFIG_ACPI`
a volitelne dalsie vnorene casti (v menu ACPI).

ACPI daemon
~~~~~~~~~~~
Na plnohodnotne vyuzitie ACPI v Linuxe je vhodne mat nainstalovany
program http://sourceforge.net/projects/acpid[ACPId]. Jeho nastavenie
je ulozene v adresari `/etc/acpi` a definuju sa tam akcie, ktore sa
maju vykonat pri konkretnych udalostiach ako napriklad stlacenie
tlacidla na vypnutie pocitaca.


CpuFreq
-------
http://www.kernel.org/pub/linux/utils/kernel/cpufreq/cpufreq.html[]

 * moznost zmeny frekvencie procesora za behu OS
 * jednoduchy pristup k informaciam a ich zmene prostrednictvom `sysfs`
   v adresari `/sys/devices/system/cpu/cpu<cislo>/cpufreq/`

Vypis obsahu sa robi standardne pomocou `# cat subor` a zapis hodnoty
do zapisovatelneho suboru sa robi pomocou `# echo hodnota > subor`.
