Hi all: In /Documentation/cpuidle/sysfs.txt, It says: "desc : Small description about the idle state(string)". when I read 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! -- Sincerely, Ren Zhen
