Member Function Documentation

virtual void IrqManager::acknowledgeIrq ( irq_id_t Id )

pure virtual

Acknoledge the IRQ reception, in case you returned false in the IrqHandler::irq() function. If this is not called there won't be any following irqs.

Parameters

[in] Id the irq's identifier

Implemented in OpenPic, Pic, HostedIrqManager, Pic, and Heathrow.

bool IrqManager::control	(	uint8_t	irq,
		ControlCode	code,
		size_t	argument
	)

virtual

Controls specific elements of a given IRQ

Reimplemented in Pic, and HostedIrqManager.

Here is the caller graph for this function:

IrqManager& IrqManager::operator= ( const IrqManager & )

private

The assignment operator

Note: NOT implemented

virtual irq_id_t IrqManager::registerIsaIrqHandler	(	uint8_t	irq,
		IrqHandler *	handler,
		bool	bEdge = `false`
	)

pure virtual

Register an ISA irq

Parameters

[in]	irq	the ISA irq number (from 0 to 15)
[in]	handler	pointer to the IrqHandler class
[in]	bEdge	whether this IRQ is edge triggered or not

Returns: the irq's identifier

Implemented in Pic, and HostedIrqManager.

Here is the caller graph for this function:

virtual irq_id_t IrqManager::registerPciIrqHandler	(	IrqHandler *	handler,
		Device *	pDevice
	)

pure virtual

Register a PCI irq

Implemented in Pic, and HostedIrqManager.

Referenced by Ehci::initialiseController().

Here is the caller graph for this function:

void IrqManager::tick ( )

virtual

Called every millisecond, typically handles IRQ mitigation.

Reimplemented in Pic, and HostedIrqManager.

Definition at line 25 of file IrqManager.cc.

Referenced by HostedTimer::irq(), and Rtc::irq().

Here is the caller graph for this function:

virtual void IrqManager::unregisterHandler	(	irq_id_t	Id,
		IrqHandler *	handler
	)

pure virtual

Unregister a previously registered IrqHandler

Parameters

[in] Id the irq's identifier

Implemented in OpenPic, Pic, HostedIrqManager, Pic, and Heathrow.
