Member Function Documentation

initState()

void gem5::RiscvProcess64::initState ( )

overrideprotectedvirtual

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 gem5::Process.

Definition at line 99 of file process.cc.
