static

Referenced by sc_core::sc_end_of_simulation_invoked().

◆ init()

void sc_gem5::Kernel::init ( )

overridevirtual

init() is called after all C++ SimObjects have been created and all ports are connected.

Initializations that are independent of unserialization but rely on a fully instantiated and connected SimObject graph should be done here.

Reimplemented from SimObject.

◆ regStats()

void sc_gem5::Kernel::regStats ( )

overridevirtual

Callback to set stat parameters.

This callback is typically used for complex stats (e.g., distributions) that need parameters in addition to a name and a description. Stat names and descriptions should typically be set from the constructor usingo from the constructor using the ADD_STAT macro.

Reimplemented from Stats::Group.

static

Definition at line 51 of file kernel.cc.

Referenced by sc_core::sc_start_of_simulation_invoked().

◆ startup()

void sc_gem5::Kernel::startup ( )

overridevirtual

startup() is the final initialization call before simulation.

All state is initialized (including unserialized state, if any, such as the curTick() value), so this is the appropriate place to schedule initial event(s) for objects that need them.

Reimplemented from SimObject.
