Constructor & Destructor Documentation

ThrottleInterface::ThrottleInterface (   )

constructor

Member Function Documentation

bool ThrottleInterface::dethrottle (   )

dethrottles cpus Returns: true if throttling supported, false otherwise

void ThrottleInterface::disableThrottling (   )

disables throttling

void ThrottleInterface::restart (   )

resets the object and clears all local values this may be used to start evaluating from the beginning

bool ThrottleInterface::throttle (  int  percent = -1  )

throttles cpus Parameters: percent  throttle cpus to that percentage -1 means maximum throttling Returns: true if throttling supported, false otherwise

bool ThrottleInterface::updateCPUState (  EventManagement *  eM  )

checks all cpus whether they should get throttled Returns: false if something went wrong, true otherwise

Member Data Documentation

bool ThrottleInterface::_cpu_is_idle [private]

whether cpu is currently idle this does not reflect whether the cpu is throttled. This variable has to be true long enough for the cpu being throttled

PROCESSOR_EVENT_STATE ThrottleInterface::_event_state [private]

indicates whether an processor event was thrown value of 1 indicates that processor.low event has been thrown, value of 0 indicates, that it has not thrown till now

unsigned long ThrottleInterface::_msecs_cpu_idle [private]

timeout when processor.low event should be thrown if it stays under the limit for this time

bool ThrottleInterface::_throttling_supported [private]

defines whether throttling is supported
