virtual void mammut::cpufreq::CpuFreq::disableBoosting ( ) const

pure virtual

Disabled frequency boosting.

virtual void mammut::cpufreq::CpuFreq::enableBoosting ( ) const

pure virtual

Enables frequency boosting.

static std::vector<topology::VirtualCore*> mammut::cpufreq::CpuFreq::filterVirtualCores	(	const std::vector< topology::VirtualCore * > &	virtualCores,
		const std::vector< topology::VirtualCoreId > &	identifiers
	)

staticprotected

From a given set of virtual cores, returns only those with specified identifiers.

Parameters

virtualCores	The set of virtual cores.
identifiers	The identifiers of the virtual cores we need.

Returns: A set of virtual cores with the specified identifiers.

Domain* mammut::cpufreq::CpuFreq::getDomain ( const topology::VirtualCore * virtualCore ) const

Gets the domain of a specified virtual core.

Parameters

virtualCore The virtual core.

Returns: The domain of the virtual core.

virtual std::vector<Domain*> mammut::cpufreq::CpuFreq::getDomains ( ) const

pure virtual

Gets the domains division of the cores.

Returns: A vector of domains.

std::vector<Domain*> mammut::cpufreq::CpuFreq::getDomains ( const std::vector< topology::VirtualCore * > & virtualCores ) const

Given a set of virtual cores, returns the domains to which these virtual cores belong.

Parameters

virtualCores The set of virtual cores.

Returns: A vector of domains.

std::vector<Domain*> mammut::cpufreq::CpuFreq::getDomains ( const topology::PhysicalCore * physicalCore ) const

Given a physical core, returns the domains covered by the virtual cores of that physical core.

Parameters

physicalCore The physical core.

Returns: A vector of domains.

std::vector<Domain*> mammut::cpufreq::CpuFreq::getDomains ( const topology::Cpu * cpu ) const

Given a CPU, returns the domains covered by the virtual cores of that CPU.

Parameters

cpu The CPU.

Returns: A vector of domains.

std::vector<Domain*> mammut::cpufreq::CpuFreq::getDomainsComplete ( const std::vector< topology::VirtualCore * > & virtualCores ) const

Given a set of virtual cores, returns the a vector of domains. The domains in this vector are only those who have all their virtual cores contained in the specified set. Accordingly, for each element D in the returned vector, D->getVirtualCores() will return a subset of virtualCores parameter. ATTENTION: There must be no duplicate virtual cores in virtualCores vector.

Parameters

virtualCores The set of virtual cores.

Returns: A vector of domains.

static Governor mammut::cpufreq::CpuFreq::getGovernorFromGovernorName ( const std::string & governorName )

static

Returns the governor identifier starting from the name of the governor.

Parameters

governorName The name of the governor.

Returns: The identifier associated to governorName, or GOVERNOR_NUM if no association is present.

static std::string mammut::cpufreq::CpuFreq::getGovernorNameFromGovernor ( Governor governor )

static

Returns the governor name associated to a specific identifier.

Parameters

governor The identifier of the governor.

Returns: The governor name associated to governor.

std::vector<RollbackPoint> mammut::cpufreq::CpuFreq::getRollbackPoints ( ) const

Returns a rollback point for each domain. They can be used to bring the domains back to the point when this function is called.

Returns: A vector of rollback points.

virtual bool mammut::cpufreq::CpuFreq::isBoostingEnabled ( ) const

pure virtual

Returns true if frequency boosting is enabled.

Returns: True if frequency boosting is enabled, false otherwise.

virtual bool mammut::cpufreq::CpuFreq::isBoostingSupported ( ) const

pure virtual

Returns true if frequency boosting is supported.

Returns: True if frequency boosting is supported, false otherwise.

bool mammut::cpufreq::CpuFreq::isGovernorAvailable ( Governor governor ) const

Checks the availability of a specific governor.

Parameters

governor The governor.

Returns: True if the governor is available for all domains, false otherwise.

void mammut::cpufreq::CpuFreq::rollback ( const std::vector< RollbackPoint > & rollbackPoints ) const

Bring the domains to the respective rollback points.

Parameters

rollbackPoints A vector of rollback points.
