Function Documentation

dumpStats()

void smaug::gem5::dumpStats	(	const char *	msg,
		int	period = 0
	)

Dumps gem5 stats to the stats.txt file.

Parameters

msg	A section label for this stats dump.
period	Dump stats every N cycles. If 0, only dumps stats once.

Definition at line 49 of file utils.cpp.

getCpuId()

int smaug::gem5::getCpuId

(

)

Returns the logical CPU number.

This does not implement the cpuid instruction!

Definition at line 71 of file utils.cpp.

quiesce()

void smaug::gem5::quiesce

(

)

Puts the CPU to sleep.

When a CPU is sleeping, it will not generate any simulation events, respond to snoop packets, etc. It can be woken with a call to wakeCpu.

Definition at line 59 of file utils.cpp.

switchCpu()

void smaug::gem5::switchCpu

(

)

Switches to the next CPU type.

Often used to implement fast-forwarding, in which switchCpu is called just before starting the detailed region of simulation.
