Constructor & Destructor Documentation

◆ SSTFrequencyLimitDetector()

geopm::SSTFrequencyLimitDetector::SSTFrequencyLimitDetector	(	PlatformIO &	platform_io,
		const PlatformTopo &	platform_topo
	)

std::vector< std::pair< unsigned int, double > > geopm::SSTFrequencyLimitDetector::get_core_frequency_limits ( unsigned int core_idx ) const

overridevirtual

Estimate the maximum achievable frequencies of a given core.

Parameters

[in] core_idx GEOPM topology index of the core to query.

Returns: A vector of alternative frequency configurations. Each vector element is a pair of a count of high-priority cores in the package, and this core's achievable frequency if that count is not exceeded.

double geopm::SSTFrequencyLimitDetector::get_core_low_priority_frequency ( unsigned int core_idx ) const

overridevirtual

Estimate the low priority frequency of a given core.

void geopm::SSTFrequencyLimitDetector::update_max_frequency_estimates ( const std::vector< double > & observed_core_frequencies )

overridevirtual

Update the estimates for maximum achievable core frequencies.

Caches the estimates to be queried by other functions in this interface.

Parameters

observed_core_frequencies The measured frequency for each core across a region of interest (e.g., epoch to epoch, across GEOPM regions, etc).
