Detailed Description

Header file for Interrupt Manager.

This encapsulates functionality related to the Classic API Interrupt Manager.

This include file contains all the constants and structures associated with the Interrupt Manager.

Macro Definition Documentation

rtems_interrupt_cause

#define rtems_interrupt_cause

(

_interrupt_to_cause

)

This routine generates an interrupt.

Note

No implementation.

rtems_interrupt_clear

#define rtems_interrupt_clear

(

_interrupt_to_clear

)

This routine clears the specified interrupt.

Note

No implementation.

rtems_interrupt_disable

#define rtems_interrupt_disable

(

_isr_cookie

)

_ISR_Disable(_isr_cookie)

Disable RTEMS Interrupt.

Note

The interrupt level shall be of type rtems_interrupt_level.

This macro is only available on uni-processor configurations. The macro rtems_interrupt_local_disable() is available on all configurations.

rtems_interrupt_enable

#define rtems_interrupt_enable

(

_isr_cookie

)

_ISR_Enable(_isr_cookie)

Enable RTEMS Interrupt.

Note

The interrupt level shall be of type rtems_interrupt_level.

This macro is only available on uni-processor configurations. The macro rtems_interrupt_local_enable() is available on all configurations.

rtems_interrupt_flash

#define rtems_interrupt_flash

(

_isr_cookie

)

_ISR_Flash(_isr_cookie)

Flash RTEMS Interrupt.

Note

The interrupt level shall be of type rtems_interrupt_level.

This macro is only available on uni-processor configurations. The macro rtems_interrupt_local_disable() and rtems_interrupt_local_enable() is available on all configurations.

rtems_interrupt_is_in_progress

bool rtems_interrupt_is_in_progress

(

void

)

_ISR_Is_in_progress()

RTEMS Interrupt Is in Progress.

A return value of true indicates that the caller is an interrupt service routine and not a thread. The directives available to an interrupt service routine are restricted.

rtems_interrupt_local_disable

#define rtems_interrupt_local_disable

(

_isr_cookie

)

_ISR_Disable_without_giant( _isr_cookie )

This macro disables the interrupts on the current processor.

On SMP configurations this will not ensure system wide mutual exclusion. Use interrupt locks instead.

Parameters

[in]

_isr_cookie

The previous interrupt level is returned. The type of this variable must be rtems_interrupt_level.

See also

rtems_interrupt_local_enable().

rtems_interrupt_local_enable

#define rtems_interrupt_local_enable

(

_isr_cookie

)

_ISR_Enable_without_giant( _isr_cookie )

This macro restores the previous interrupt level on the current processor.

Parameters

[in]

_isr_cookie

The previous interrupt level returned by rtems_interrupt_local_disable().
