Reimplemented from BaseCPU.

Definition at line 199 of file base.cc.

References BaseCPU::CPU_STATE_SLEEP, BaseCPU::suspendContext(), and BaseCPU::updateCycleCounters().

◆ htmSendAbortSignal()

virtual void BaseSimpleCPU::htmSendAbortSignal ( HtmFailureFaultCause cause )

pure virtual

This function is used to instruct the memory subsystem that a transaction should be aborted and the speculative state should be thrown away.

This is called in the transaction's very last breath in the core. Afterwards, the core throws away its speculative state and resumes execution at the point the transaction started, i.e. reverses time. When instruction execution resumes, the core expects the memory subsystem to be in a stable, i.e. pre-speculative, state as well.

Implemented in TimingSimpleCPU, and AtomicSimpleCPU.

Referenced by SimpleThread::htmAbortTransaction().

◆ init()

void BaseSimpleCPU::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 BaseCPU.

Reimplemented in TimingSimpleCPU.

◆ initiateHtmCmd()

virtual Fault BaseSimpleCPU::initiateHtmCmd ( Request::Flags flags )

pure virtual

Hardware transactional memory commands (HtmCmds), e.g.

start a transaction and commit a transaction, are memory operations but are neither really (true) loads nor stores. For this reason the interface is extended and initiateHtmCmd() is used to instigate the command.

Implemented in TimingSimpleCPU, and AtomicSimpleCPU.
