Functions
RTEMS_WEAK rtems_interrupt_entry **	bsp_interrupt_get_dispatch_table_slot (rtems_vector_number index)
	Gets a reference to the interrupt handler table slot associated with the index.

rtems_status_code	bsp_interrupt_check_and_lock (rtems_vector_number vector, rtems_interrupt_handler routine)
	Checks the vector and routine. When the checks were successful, the interrupt support lock will be obtained.

rtems_interrupt_entry *	bsp_interrupt_entry_find (rtems_vector_number vector, rtems_interrupt_handler routine, void arg, rtems_interrupt_entry **previous_next)

void	bsp_interrupt_initialize (void)
	Initialize Interrupt Manager implementation.

rtems_status_code	rtems_interrupt_entry_install (rtems_vector_number vector, rtems_option options, rtems_interrupt_entry *entry)
	Installs the interrupt entry at the interrupt vector.

Variables
rtems_interrupt_entry *	bsp_interrupt_dispatch_table [BSP_INTERRUPT_DISPATCH_TABLE_SIZE]
	Each member of this table references the first installed entry at the corresponding interrupt vector or is NULL.

uint8_t	bsp_interrupt_handler_unique_table [(BSP_INTERRUPT_DISPATCH_TABLE_SIZE+7+1)/8]
	This table contains a bit map which indicates if an entry is unique or shared.

Detailed Description

This source file contains the generic interrupt controller support implementation.

Function Documentation

◆ bsp_interrupt_check_and_lock()

rtems_status_code bsp_interrupt_check_and_lock	(	rtems_vector_number	vector,
		rtems_interrupt_handler	handler
	)

Checks the vector and routine. When the checks were successful, the interrupt support lock will be obtained.

Parameters

vector	is the interrupt vector number to check.
routine	is the routine to check.

Return values

RTEMS_SUCCESSFUL	The requested operation was successful.
RTEMS_INCORRECT_STATE	The interrupt support was not initialized.
RTEMS_CALLED_FROM_ISR	The function was called from within interrupt context.
RTEMS_INVALID_ADDRESS	The `routine` parameter was NULL.
RTEMS_INVALID_ID	There was no interrupt vector associated with the number specified by `vector`.

◆ bsp_interrupt_get_dispatch_table_slot()

RTEMS_WEAK rtems_interrupt_entry ** bsp_interrupt_get_dispatch_table_slot ( rtems_vector_number index )

Gets a reference to the interrupt handler table slot associated with the index.

Returns: Returns a reference to the interrupt handler table slot associated with the index.

Variable Documentation

◆ bsp_interrupt_handler_unique_table

uint8_t bsp_interrupt_handler_unique_table[(BSP_INTERRUPT_DISPATCH_TABLE_SIZE+7+1)/8]

This table contains a bit map which indicates if an entry is unique or shared.

If the bit associated with a vector is set, then the entry is unique, otherwise it may be shared. If the bit with index BSP_INTERRUPT_DISPATCH_TABLE_SIZE is set, then the interrupt support is initialized, otherwise it is not initialized.
