int __ht_create_irq	(	struct pci_dev *	dev,
		int	idx,
		ht_irq_update_t *	update
	)

__ht_create_irq - create an irq and attach it to a device. : The hypertransport device to find the irq capability on. : Which of the possible irqs to attach to. : Function to be called when changing the htirq message

The irq number of the new irq or a negative error value is returned.

int ht_create_irq	(	struct pci_dev *	dev,
		int	idx
	)

ht_create_irq - create an irq and attach it to a device. : The hypertransport device to find the irq capability on. : Which of the possible irqs to attach to.

ht_create_irq needs to be called for all hypertransport devices that generate irqs.

The irq number of the new irq or a negative error value is returned.

(

unsigned int

irq

)

ht_destroy_irq - destroy an irq created with ht_create_irq : irq to be destroyed

This reverses ht_create_irq removing the specified irq from existence. The irq should be free before this happens.
