Detailed Description

Fixed Priority QoS Policy.

Fixed Priority Policy: based on a configured RequestorID to priority map, it returns a fixed QoS priority value: every requestor has a fixed priority.

Member Function Documentation

◆ init()

void QoS::FixedPriorityPolicy::init ( )

overridevirtual

init() is called after all C++ SimObjects have been created and all ports are connected.

Initializations that are independent of unserialization but rely on a fully instantiated and connected SimObject graph should be done here.

Reimplemented from QoS::Policy.

Definition at line 57 of file policy_fixed_prio.cc.

◆ initRequestorName()

void QoS::FixedPriorityPolicy::initRequestorName	(	std::string	requestor,
		uint8_t	priority
	)

Initialize the fixed requestor's priority by providing the requestor's name and priority value.

The requestor's name has to match a name in the system.

Parameters

requestor	requestor's name to lookup.
priority	priority value for the requestor

Definition at line 62 of file policy_fixed_prio.cc.

References priorityMap.

◆ initRequestorObj()

void QoS::FixedPriorityPolicy::initRequestorObj	(	const SimObject *	requestor,
		uint8_t	priority
	)

Initialize the fixed requestor's priority by providing the requestor's SimObject pointer and priority value.

Parameters

requestor	requestor's SimObject pointer to lookup.
priority	priority value for the requestor

Definition at line 69 of file policy_fixed_prio.cc.

References priorityMap.

◆ schedule()

uint8_t QoS::FixedPriorityPolicy::schedule	(	const RequestorID	id,
		const uint64_t	data
	)

overridevirtual

Schedules a packet based on fixed priority configuration.

Parameters

id	requestor id to schedule
data	data to schedule

Returns: QoS priority value

Implements QoS::Policy.
