References bootldr, Loader::ObjectFile::entryPoint(), and kernelEntry.

◆ initState()

void ArmISA::FsWorkload::initState ( )

initState() is called on each SimObject when not restoring from a checkpoint.

This provides a hook for state initializations that are only required for a "cold start".

Reimplemented from SimObject.

Reimplemented in ArmISA::FsLinux.
