Member Function Documentation

◆ initState()

void ArmISA::FsFreebsd::initState ( )

overridevirtual

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.

◆ mapPid()

void ArmISA::FsFreebsd::mapPid	(	ThreadContext *	tc,
		uint32_t	pid
	)

This function creates a new task Id for the given pid.

Parameters

tc	thread context that is currentyl executing

◆ params()

◆ enableContextSwitchStatsDump

◆ secDataAddr

Addr ArmISA::FsFreebsd::secDataAddr

private

Definition at line 99 of file fs_workload.hh.

◆ secDataPtrAddr

Addr ArmISA::FsFreebsd::secDataPtrAddr

private

These variables store addresses of important data structures that are normaly kept coherent at boot with cache mainetence operations.

Since these operations aren't supported in gem5, we keep them coherent by making them uncacheable until all processors in the system boot.

Definition at line 98 of file fs_workload.hh.

◆ skipUDelay

PCEvent* ArmISA::FsFreebsd::skipUDelay = nullptr

private

PC based event to skip udelay(<time>) calls and quiesce the processor for the appropriate amount of time.

This is not functionally required but does speed up simulation.

Definition at line 91 of file fs_workload.hh.

Referenced by FsFreebsd(), and ~FsFreebsd().

◆ taskFile

std::ostream* ArmISA::FsFreebsd::taskFile

This is a file that is placed in the run directory that prints out mappings between taskIds and OS process IDs.

Definition at line 68 of file fs_workload.hh.

◆ taskMap

std::map<uint32_t, uint32_t> ArmISA::FsFreebsd::taskMap

This map stores a mapping of OS process IDs to internal Task IDs.

The mapping is done because the stats system doesn't tend to like vectors that are much greater than 1000 items and the entire process space is 65K.
