◆ getBootLoader()

Loader::ObjectFile * ArmISA::FsWorkload::getBootLoader ( Loader::ObjectFile *const obj )

protected

Get a boot loader that matches the kernel.

Parameters

obj	Kernel binary

Returns: Pointer to boot loader ObjectFile or nullptr if there is no matching boot loader.

◆ 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.
