Detailed Description

This group contains the Interrupt Manager implementation.

The Interrupt Manager implementation manages a sequence of interrupt vector numbers greater than or equal to zero and less than BSP_INTERRUPT_VECTOR_COUNT. It provides methods to install, remove, and dispatch interrupt entries for each vector number, see bsp_interrupt_dispatch_entries().

The entry points to a list of interrupt entries are stored in a table (= dispatch table).

You have to configure the Interrupt Manager implementation in the <bsp/irq.h> file for each BSP. For a minimum configuration you have to provide BSP_INTERRUPT_VECTOR_COUNT.

For boards with small memory requirements you can define BSP_INTERRUPT_USE_INDEX_TABLE. With an enabled index table the dispatch table will be accessed via a small index table. You can define the size of the dispatch table with BSP_INTERRUPT_DISPATCH_TABLE_SIZE.

You have to provide some special routines in your BSP (follow the links for the details):

Optionally, the BSP may define the following macros to customize the vector installation after installing the first entry and the vector removal before removing the last entry:

bsp_interrupt_vector_install()
bsp_interrupt_vector_remove()

The following now deprecated functions are provided for backward compatibility:

BSP_get_current_rtems_irq_handler()
BSP_install_rtems_irq_handler()
BSP_install_rtems_shared_irq_handler()
BSP_remove_rtems_irq_handler()
BSP_rtems_irq_mngt_set()
BSP_rtems_irq_mngt_get()

Function Documentation

◆ bsp_interrupt_clear()

rtems_status_code bsp_interrupt_clear ( rtems_vector_number vector )

Clears the interrupt vector.

Parameters

vector is the number of the interrupt vector to clear. It shall be valid.

Return values

RTEMS_SUCCESSFUL	The requested operation was successful.
RTEMS_UNSATISFIED	The request to cause the interrupt vector has not been satisfied. The presence of this error condition is implementation-defined. The interrupt vector attributes obtained by rtems_interrupt_get_attributes() should indicate if it is possible to clear a particular interrupt vector.

◆ bsp_interrupt_facility_initialize()

void bsp_interrupt_facility_initialize ( void )

BSP specific initialization.

This routine will be called form bsp_interrupt_initialize() and shall do the following:

Initialize the facilities that call bsp_interrupt_handler_dispatch(). For example on PowerPC the external exception handler.
Initialize the interrupt controller. You shall set the interrupt controller in a state such that interrupts are disabled for all vectors. The vectors will be enabled with your bsp_interrupt_vector_enable() function and disabled via your bsp_interrupt_vector_disable() function. These functions have to work afterwards.

BSP specific initialization.

Resets vectored interrupt interface to default state. Disables all interrupts. Set all sources as IRQ (not FIR).

Return values

RTEMS_SUCCESSFUL All is set

◆ bsp_interrupt_get_attributes()

rtems_status_code bsp_interrupt_get_attributes	(	rtems_vector_number	vector,
		rtems_interrupt_attributes *	attributes
	)

Gets the attributes of the interrupt vector.

Parameters

	vector	is the interrupt vector number. It shall be valid.
[out]	attributes	is the pointer to an rtems_interrupt_attributes object. When the function call is successful, the attributes of the interrupt vector will be stored in this object. The pointer shall not be NULL. The object shall be cleared to zero by the caller.

Return values

RTEMS_SUCCESSFUL The requested operation was successful.

Gets the attributes of the interrupt vector.

Enables HW interrupt for specified vector

Parameters

[in] vector vector of the isr which needs to be enabled.

Return values

RTEMS_INVALID_ID	vector is invalid.
RTEMS_SUCCESSFUL	interrupt source enabled.

◆ bsp_interrupt_handler_default()

void bsp_interrupt_handler_default ( rtems_vector_number vector )

Default interrupt handler.

This routine will be called from bsp_interrupt_handler_dispatch() with the current vector number vector when the handler list for this vector is empty or the vector number is out of range.

Note: This function must cope with arbitrary vector numbers vector.

◆ bsp_interrupt_initialize()

void bsp_interrupt_initialize ( void )

Initialize Interrupt Manager implementation.

You must call this function before you can install, remove and dispatch interrupt entries. There is no protection against concurrent initialization. This function must be called at most once. The BSP specific bsp_interrupt_facility_initialize() function will be called after all internals are initialized. If the BSP specific initialization fails, then this is a fatal error. The fatal error source is RTEMS_FATAL_SOURCE_BSP and the fatal error code is BSP_FATAL_INTERRUPT_INITIALIZATION.

◆ bsp_interrupt_is_pending()

rtems_status_code bsp_interrupt_is_pending	(	rtems_vector_number	vector,
		bool *	pending
	)

Checks if the interrupt is pending.

The function checks if the interrupt associated with the interrupt vector specified by vector was pending for the processor executing the function call at some time point during the call.

Parameters

	vector	is the interrupt vector number. It shall be valid.
[out]	pending	is the pointer to a `bool` object. It shall not be `NULL`. When the function call is successful, the pending status of the interrupt associated with the interrupt vector specified by `vector` will be stored in this object. When the interrupt was pending for the processor executing the function call at some time point during the call, the object will be set to true, otherwise to false.

Return values

RTEMS_SUCCESSFUL	The requested operation was successful.
RTEMS_UNSATISFIED	The request to get the pending status has not been satisfied.

◆ bsp_interrupt_raise()

rtems_status_code bsp_interrupt_raise ( rtems_vector_number vector )

Causes the interrupt vector.

Parameters

vector is the number of the interrupt vector to cause. It shall be valid.

Return values

RTEMS_SUCCESSFUL	The requested operation was successful.
RTEMS_UNSATISFIED	The request to raise the interrupt vector has not been satisfied. The presence of this error condition is implementation-defined. The interrupt vector attributes obtained by rtems_interrupt_get_attributes() should indicate if it is possible to raise a particular interrupt vector.

◆ bsp_interrupt_vector_disable()

rtems_status_code bsp_interrupt_vector_disable ( rtems_vector_number vector )

Disables the interrupt vector.

This function shall disable the vector at the corresponding facility (in most cases the interrupt controller). It will be called then the last entry is removed for the vector in rtems_interrupt_entry_remove() for example.

Note: The implementation should use bsp_interrupt_assert( bsp_interrupt_is_valid_vector( vector ) ) to validate the vector number in ::RTEMS_DEBUG configurations.

Parameters

vector is the interrupt vector number.

Return values

RTEMS_SUCCESSFUL	The requested operation was successful.
RTEMS_UNSATISFIED	The request to disable the interrupt vector has not been satisfied. The presence of this error condition is implementation-defined. The interrupt vector attributes obtained by rtems_interrupt_get_attributes() should indicate if it is possible to disable a particular interrupt vector.

Disables the interrupt vector.

Disables HW interrupt for specified vector

Parameters

[in] vector vector of the isr which needs to be disabled.

Return values

RTEMS_INVALID_ID	vector is invalid.
RTEMS_SUCCESSFUL	interrupt source disabled.

◆ bsp_interrupt_vector_enable()

rtems_status_code bsp_interrupt_vector_enable ( rtems_vector_number vector )

Enables the interrupt vector.

This function shall enable the vector at the corresponding facility (in most cases the interrupt controller). It will be called then the first entry is installed for the vector in rtems_interrupt_entry_install() for example.

Note: The implementation should use bsp_interrupt_assert( bsp_interrupt_is_valid_vector( vector ) ) to validate the vector number in ::RTEMS_DEBUG configurations.

Parameters

vector is the interrupt vector number.

Return values

RTEMS_SUCCESSFUL	The requested operation was successful.
RTEMS_UNSATISFIED	The request to enable the interrupt vector has not been satisfied. The presence of this error condition is implementation-defined. The interrupt vector attributes obtained by rtems_interrupt_get_attributes() should indicate if it is possible to enable a particular interrupt vector.

◆ bsp_interrupt_vector_is_enabled()

rtems_status_code bsp_interrupt_vector_is_enabled	(	rtems_vector_number	vector,
		bool *	enabled
	)

Checks if the interrupt is enabled.

The function checks if the interrupt associated with the interrupt vector specified by vector was enabled for the processor executing the function call at some time point during the call.

Parameters

	vector	is the interrupt vector number. It shall be valid.
[out]	enabled	is the pointer to a `bool` object. It shall not be `NULL`. When the function call is successful, the enabled status of the interrupt associated with the interrupt vector specified by `vector` will be stored in this object. When the interrupt was enabled for the processor executing the function call at some time point during the call, the object will be set to true, otherwise to false.
