Detailed Description

GICv3 ITS module.

This class is just modelling a pio device with its memory mapped registers. Most of the ITS functionalities are implemented as processes (ItsProcess) objects, like ItsTranslation or ItsCommand. Main job of Gicv3Its is to spawn those processes upon receival of packets.

◆ drain()

DrainState gem5::Gicv3Its::drain ( )
overridevirtual

Draining is the process of clearing out the states of SimObjects.These are the SimObjects that are partially executed or are partially in flight.

Draining is mostly used before forking and creating a check point.

This function notifies an object that it needs to drain its state.

If the object does not need further simulation to drain internal buffers, it returns DrainState::Drained and automatically switches to the Drained state. If the object needs more simulation, it returns DrainState::Draining and automatically enters the Draining state. Other return values are invalid.

Note
An object that has entered the Drained state can be disturbed by other objects in the system and consequently stop being drained. These perturbations are not visible in the drain state. The simulator therefore repeats the draining process until all objects return DrainState::Drained on the first call to drain().
Returns
DrainState::Drained if the object is drained at this point in time, DrainState::Draining if it needs further simulation.

Implements gem5::Drainable.

◆ getPort()

Port & gem5::Gicv3Its::getPort ( const std::string &  if_name,
PortID  idx 
)
overridevirtual

Get a port with a given name and index.

This is used at binding time and returns a reference to a protocol-agnostic port.

gem5 has a request and response port interface. All memory objects are connected together via ports. These ports provide a rigid interface between these memory objects. These ports implement three different memory system modes: timing, atomic, and functional. The most important mode is the timing mode and here timing mode is used for conducting cycle-level timing experiments. The other modes are only used in special circumstances and should not be used to conduct cycle-level timing experiments. The other modes are only used in special circumstances. These ports allow SimObjects to communicate with each other.

Parameters
if_namePort name
idxIndex in the case of a VectorPort
Returns
A reference to the given port

Reimplemented from gem5::SimObject.
