Detailed Description

RTEMS thread and RTEMS_ASR modes.

This encapsulates functionality related to the task modes supported by the Classic API Task Manager.

This include file contains all constants and structures associated with the RTEMS thread and RTEMS_ASR modes.

Macro Definition Documentation

◆ RTEMS_ASR

#define RTEMS_ASR 0x00000000

This mode constant is used to indicate signal processing is enabled.

◆ RTEMS_ASR_MASK

#define RTEMS_ASR_MASK 0x00000400

This mode constant corresponds to the signal enable/disable bit.

Referenced by _Modes_Is_asr_disabled().

◆ RTEMS_INTERRUPT_LEVEL

#define RTEMS_INTERRUPT_LEVEL ( _mode_set ) ( (_mode_set) & RTEMS_INTERRUPT_MASK )

RTEMS_INTERRUPT_LEVEL.

This function returns the processor dependent interrupt level which corresponds to the requested interrupt level.

Note: RTEMS supports 256 interrupt levels using the least significant eight bits of MODES.CONTROL. On any particular CPU, fewer than 256 levels may be supported.

◆ RTEMS_NO_ASR

#define RTEMS_NO_ASR 0x00000400

This mode constant is used to indicate signal processing is disabled.

Referenced by _Modes_Is_asr_disabled().

◆ RTEMS_NO_PREEMPT

#define RTEMS_NO_PREEMPT 0x00000100

This mode constant is used to indicate preemption is disabled.

◆ RTEMS_NO_TIMESLICE

#define RTEMS_NO_TIMESLICE 0x00000000

This mode constant is used to indicate timeslicing is disabled.

◆ RTEMS_PREEMPT

#define RTEMS_PREEMPT 0x00000000

This mode constant is used to indicate preemption is enabled.

Referenced by _Modes_Is_preempt().

◆ RTEMS_PREEMPT_MASK

#define RTEMS_PREEMPT_MASK 0x00000100

This mode constant corresponds to the preemption enable/disable bit.
