[QUERY] cpuidle in SYSFS: /sys/devices/system/cpu/cpu0/cpuidle/state0/desc

[Ren Zhen]

Hi all:
In /Documentation/cpuidle/sysfs.txt, It says:
"desc : Small description about the idle state(string)".

when I cat desc:
------------------------------------------------------------------------
mysystem:/sys/devices/system/cpu/cpu0/cpuidle/state0/# cat desc
CPUIDLE CORE POLL IDLE
------------------------------------------------------------------------

Here is my question:What the meaning of  ‘CPUIDLE CORE POLL IDLE'?

Any help will be appreciated!
