Detailed Description

This section describes configuration options related to selecting a scheduling algorithm for an application. A scheduler configuration is optional and only necessary in very specific circumstances. A normal application configuration does not need any of the configuration options described in this section.

By default, the Deterministic Priority Scheduler algorithm is used in uniprocessor configurations. In case SMP is enabled and the configured maximum processors (CONFIGURE_MAXIMUM_PROCESSORS) is greater than one, then the Earliest Deadline First SMP Scheduler is selected as the default scheduler algorithm.

For the schedulers provided by RTEMS (see Scheduling Concepts), the configuration is straightforward. All that is required is to define the configuration option which specifies which scheduler you want for in your application.

The pluggable scheduler interface also enables the user to provide their own scheduling algorithm. If you choose to do this, you must define multiple configuration option.

Macro Definition Documentation

◆ CONFIGURE_CBS_MAXIMUM_SERVERS

#define CONFIGURE_CBS_MAXIMUM_SERVERS

This configuration option is an integer define.

The value of this configuration option defines the maximum number Constant Bandwidth Servers that can be concurrently active.

Default Value
The default value is CONFIGURE_MAXIMUM_TASKS.
Constraints

The following constraints apply to this configuration option:

  • The value of the configuration option shall be greater than or equal to zero.
  • The value of the configuration option shall be less than or equal to SIZE_MAX.
  • The value of the configuration option shall be less than or equal to a BSP-specific and application-specific value which depends on the size of the memory available to the application.
Notes
This configuration option is only evaluated if the configuration option CONFIGURE_SCHEDULER_CBS is defined.

◆ CONFIGURE_MAXIMUM_PRIORITY

#define CONFIGURE_MAXIMUM_PRIORITY

This configuration option is an integer define.

For the following schedulers

this configuration option specifies the maximum numeric priority of any task for these schedulers and one less that the number of priority levels for these schedulers. For all other schedulers provided by RTEMS, this configuration option has no effect.

Default Value
The default value is 255.
Constraints
The value of the configuration option shall be equal to 3, 7, 31, 63, 127, or 255.
Notes

The numerically greatest priority is the logically lowest priority in the system and will thus be used by the IDLE task.

Priority zero is reserved for internal use by RTEMS and is not available to applications.

Reducing the number of priorities through this configuration option reduces the amount of memory allocated by the schedulers listed above. These schedulers use a chain control structure per priority and this structure consists of three pointers. On a 32-bit architecture, the allocated memory is 12 bytes * (CONFIGURE_MAXIMUM_PRIORITY + 1), e.g. 3072 bytes for 256 priority levels (default), 48 bytes for 4 priority levels (CONFIGURE_MAXIMUM_PRIORITY == 3).

The default value is 255, because RTEMS shall support 256 priority levels to be compliant with various standards. These priorities range from 0 to 255.

◆ CONFIGURE_SCHEDULER_ASSIGNMENTS

#define CONFIGURE_SCHEDULER_ASSIGNMENTS

This configuration option is an initializer define.

The value of this configuration option is used to initialize the initial scheduler to processor assignments.

Default Value
The default value of this configuration option is computed so that the default scheduler is assigned to each configured processor (up to 32).
Constraints

The following constraints apply to this configuration option:

  • The value of the configuration option shall be a list of the following macros:

    • RTEMS_SCHEDULER_ASSIGN( scheduler_index, attributes )
    • RTEMS_SCHEDULER_ASSIGN_NO_SCHEDULER

    The scheduler_index macro parameter shall be a valid index of the scheduler table defined by the CONFIGURE_SCHEDULER_TABLE_ENTRIES configuration option.

    The attributes macro parameter shall be set to exactly one of the following constants:

    • RTEMS_SCHEDULER_ASSIGN_PROCESSOR_MANDATORY
    • RTEMS_SCHEDULER_ASSIGN_PROCESSOR_OPTIONAL
  • The value of the configuration option shall be a list of exactly CONFIGURE_MAXIMUM_PROCESSORS elements.
Notes

Where the system was built with SMP support enabled, this configuration option is evaluated, otherwise it is ignored.

This is an advanced configuration option, see Clustered Scheduler Configuration.

RTEMS allows the application to provide its own task/thread scheduling algorithm. In order to do this, one shall define CONFIGURE_SCHEDULER_USER to indicate the application provides its own scheduling algorithm. If CONFIGURE_SCHEDULER_USER is defined then the following additional macros shall be defined:

  • CONFIGURE_SCHEDULER shall be defined to a static definition of the scheduler data structures of the user scheduler.
  • CONFIGURE_SCHEDULER_TABLE_ENTRIES shall be defined to a scheduler table entry initializer for the user scheduler.
  • CONFIGURE_SCHEDULER_USER_PER_THREAD shall be defined to the type of the per-thread information of the user scheduler.

At this time, the mechanics and requirements for writing a new scheduler are evolving and not fully documented. It is recommended that you look at the existing Deterministic Priority Scheduler in cpukit/score/src/schedulerpriority*.c for guidance. For guidance on the configuration macros, please examine cpukit/include/rtems/confdefs/scheduler.h for how these are defined for the Deterministic Priority Scheduler.
