Member Enumeration Documentation

anonymous enum

Enumerator:

TYPE_REQUEST_TIMER
TYPE_REQUEST_TIME
TYPE_REQUEST_LAST_TIMEOUT

Constructor & Destructor Documentation

TimerProtocol::TimerProtocol ( unsigned  cap_base, unsigned  instance = 0  )

inline

Member Function Documentation

unsigned TimerProtocol::time ( Utcb &  utcb, timevalue &  wallclocktime, timevalue &  timestamp  )

inline

Returns the wall clock time in microseconds.

It also contains a timestamp of the Motherboard clock in microseconds, to be able to adjust to the time already passed and to detect out-of-date values.

unsigned TimerProtocol::timer ( Utcb &  utcb, timevalue  abstime  )

inline

Program timer for timer.abstime.

unsigned TimerProtocol::triggered_timeouts ( Utcb &  utcb, unsigned &  count  )

inline

Member Data Documentation

const unsigned long TimerProtocol::WALLCLOCK_FREQUENCY = Config::WALLCLOCK_FREQUENCY

static

Timer infrastructure.

There is no frequency and clock here, as all is based on the same clocksource.
