This encapsulates functionality related to the task modes supported by the Classic API Task Manager.
◆ RTEMS_ALL_MODE_MASKS
#define RTEMS_ALL_MODE_MASKS 0x0000ffff |
The following constants define the individual modes and masks which may be used to compose a mode set and to alter modes.
◆ 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.
◆ RTEMS_CURRENT_MODE
#define RTEMS_CURRENT_MODE 0 |
This mode constant is used when the user wishes to obtain their current execution mode.
◆ RTEMS_DEFAULT_MODES
#define RTEMS_DEFAULT_MODES 0x00000000 |
This mode constant is the default mode set.
◆ RTEMS_INTERRUPT_LEVEL
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_INTERRUPT_MASK
This mode constant corresponds to the interrupt enable/disable bits.
◆ RTEMS_NO_ASR
#define RTEMS_NO_ASR 0x00000400 |
This mode constant is used to indicate signal processing is 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.
◆ RTEMS_PREEMPT_MASK
#define RTEMS_PREEMPT_MASK 0x00000100 |
This mode constant corresponds to the preemption enable/disable bit.
◆ RTEMS_TIMESLICE
#define RTEMS_TIMESLICE 0x00000200 |
This mode constant is used to indicate timeslicing is enabled.
◆ RTEMS_TIMESLICE_MASK
#define RTEMS_TIMESLICE_MASK 0x00000200 |
This mode constant corresponds to the timeslice enable/disable bit.
◆ rtems_mode
The following type defines the control block used to manage each a mode set.
◆ rtems_interrupt_level_body()
rtems_mode rtems_interrupt_level_body |
( |
uint32_t |
level | ) |
|
Body for RTEMS_INTERRUPT_LEVEL Macro.
