Files
file	modes.h
	This header file defines the task modes of the Task Manager API.

Macros
#define	RTEMS_INTERRUPT_MASK   CPU_MODES_INTERRUPT_MASK
	This task mode constant corresponds to the interrupt enable/disable bits.
#define	RTEMS_ALL_MODE_MASKS   0x0000ffff
	This task mode constant is a mask with all mode bits set.
#define	RTEMS_ASR   0x00000000
	This task mode constant is used to indicate signal processing is disabled.
#define	RTEMS_ASR_MASK   0x00000400
	This mode constant corresponds to the signal enable/disable bit.
#define	RTEMS_CURRENT_MODE   0
	This task mode constant is used when the user wishes to obtain the current task mode of the executing task.
#define	RTEMS_DEFAULT_MODES   0x00000000
	This task mode constant represents the default mode set.
#define	RTEMS_INTERRUPT_LEVEL(_interrupt_level)   ( ( _interrupt_level ) & RTEMS_INTERRUPT_MASK )
	Returns the task mode with the processor-dependent interrupt level corresponding to the specified interrupt level. More...
#define	RTEMS_NO_ASR   0x00000400
	This task mode constant is used to indicate signal processing is disabled.
#define	RTEMS_NO_PREEMPT   0x00000100
	This task mode constant is used to indicate preemption is disabled.
#define	RTEMS_NO_TIMESLICE   0x00000000
	This task mode constant is used to indicate timeslicing is disabled.
#define	RTEMS_PREEMPT   0x00000000
	This task mode constant is used to indicate preemption is enabled.
#define	RTEMS_PREEMPT_MASK   0x00000100
	This task mode constant corresponds to the preemption enable/disable bit.
#define	RTEMS_TIMESLICE   0x00000200
	This task mode constant is used to indicate timeslicing is enabled.
#define	RTEMS_TIMESLICE_MASK   0x00000200
	This task mode constant corresponds to the timeslice enable/disable bit.

Typedefs
typedef uint32_t	rtems_mode
	This type is used to represent a task mode set.

Functions
rtems_mode	rtems_interrupt_level_body (uint32_t level)
	Returns the return value of RTEMS_INTERRUPT_LEVEL() for the specified interrupt level. More...

Variables
const uint32_t	rtems_interrupt_mask
	This task mode constant has the same value as RTEMS_INTERRUPT_MASK. More...

Detailed Description

Macro Definition Documentation

RTEMS_INTERRUPT_LEVEL

#define RTEMS_INTERRUPT_LEVEL

(

_interrupt_level

)

( ( _interrupt_level ) & RTEMS_INTERRUPT_MASK )

Returns the task mode with the processor-dependent interrupt level corresponding to the specified interrupt level.

The Classic API supports 256 interrupt levels using the least significant eight bits of the mode set. On any particular processor variant, fewer than 256 levels may be supported. At least level 0 (all interrupts enabled) and level 1 (interrupts disabled, on most architectures) are supported.

Parameters

_interrupt_level

is the interrupt level.

Definition at line 154 of file modes.h.

Function Documentation

rtems_interrupt_level_body()

rtems_mode rtems_interrupt_level_body

(

uint32_t

level

)

Returns the return value of RTEMS_INTERRUPT_LEVEL() for the specified interrupt level.

This function is used by bindings from languages other than C and C++.

Parameters

level

is the interrupt level.

Variable Documentation

rtems_interrupt_mask

const uint32_t rtems_interrupt_mask

This task mode constant has the same value as RTEMS_INTERRUPT_MASK.
