Detailed Description

Software-managed ISR table.

Data types for a software-managed ISR table, with a parameter per-ISR.

Macro Definition Documentation

INTC_BASE_ISR_TBL_OFFSET

#define INTC_BASE_ISR_TBL_OFFSET

(

node_id

)

Value:

        Z_SW_ISR_TBL_KCONFIG_BY_ALVL(DT_INTC_GET_AGGREGATOR_LEVEL(node_id))

Get an interrupt controller node's level base ISR table offset.

Parameters

node_id

node identifier of the interrupt controller

Returns

CONFIG_2ND_LVL_ISR_TBL_OFFSET if node_id is a second level aggregator, CONFIG_3RD_LVL_ISR_TBL_OFFSET if it is a third level aggregator

INTC_CHILD_ISR_TBL_OFFSET

#define INTC_CHILD_ISR_TBL_OFFSET

(

node_id

)

Value:

        (INTC_BASE_ISR_TBL_OFFSET(node_id) +                                                       \
         (DT_NODE_CHILD_IDX(node_id) * CONFIG_MAX_IRQ_PER_AGGREGATOR))

Get the SW ISR table offset for a child interrupt controller.

This macro is a alternative form of the INTC_INST_ISR_TBL_OFFSET. This is used by pseudo interrupt controller devices that are child of a main interrupt controller device.

Parameters

node_id

node identifier of the child interrupt controller

Returns

Software ISR table offset of the child

INTC_INST_ISR_TBL_OFFSET

#define INTC_INST_ISR_TBL_OFFSET

(

inst

)

Value:

        (INTC_BASE_ISR_TBL_OFFSET(DT_DRV_INST(inst)) + (inst * CONFIG_MAX_IRQ_PER_AGGREGATOR))

Get the SW ISR table offset for an instance of interrupt controller.

Parameters

inst	DT_DRV_COMPAT interrupt controller driver instance number

Returns

Software ISR table offset of the interrupt controller

IRQ_PARENT_ENTRY_DEFINE

#define IRQ_PARENT_ENTRY_DEFINE	(		_name,
			_dev,
			_irq,
			_offset,
			_level )

Value:

        static const STRUCT_SECTION_ITERABLE_ALTERNATE(intc_table, _irq_parent_entry, _name) = {   \
                .dev = _dev,                                                                       \
                .level = _level,                                                                   \
                .irq = _irq,                                                                       \
                .offset = _offset,                                                                 \
        }

Register an interrupt controller with the software ISR table.

Parameters

_name	Name of the interrupt controller (must be unique)
_dev	Pointer to the interrupt controller device instance
_irq	Interrupt controller IRQ number
_offset	Software ISR table offset of the interrupt controller
_level	Interrupt controller aggregator level

IRQ_TABLE_SIZE

#define IRQ_TABLE_SIZE   (CONFIG_NUM_IRQS - CONFIG_GEN_IRQ_START_VECTOR)

ISR_FLAG_DIRECT

#define ISR_FLAG_DIRECT   BIT(0)

This interrupt gets put directly in the vector table.
