Interrupt Initialization and Destruction Functions

Use the following functions to create and remove interrupts:

ddi_intr_alloc(9F)

Allocates system resources and interrupt vectors for the specified type of interrupt.

ddi_intr_free(9F)

Releases the system resources and interrupt vectors for a specified interrupt handle.

ddi_intr_set_cap(9F)

Sets the capability of the specified interrupt through the use of the DDI_INTR_FLAG_LEVEL and DDI_INTR_FLAG_EDGE flags.

ddi_intr_add_handler(9F)

Adds an interrupt handler.

ddi_intr_dup_handler(9F)

Use with MSI-X only. Copies an address and data pair for an allocated interrupt vector to an unused interrupt vector on the same device.

ddi_intr_remove_handler(9F)

Removes the specified interrupt handler.

ddi_intr_enable(9F)

Enables the specified interrupt.

ddi_intr_disable(9F)

Disables the specified interrupt.

ddi_intr_block_enable(9F)

Use with MSI only. Enables the specified range of interrupts.

ddi_intr_block_disable(9F)

Use with MSI only. Disables the specified range of interrupts.

ddi_intr_set_mask(9F)

Sets an interrupt mask if the specified interrupt is enabled.

ddi_intr_clr_mask(9F)

Clears an interrupt mask if the specified interrupt is enabled.

ddi_intr_get_pending(9F)

Reads the interrupt pending bit if such a bit is supported by either the host bridge or the device.
