Field Documentation
◆ do_zero_of_workspace
| bool rtems_configuration_table::do_zero_of_workspace |
If this element is TRUE, then RTEMS will zero the Executive Workspace.
When this element is FALSE, it is assumed that the BSP or invoking environment has ensured that memory was cleared before RTEMS was invoked.
◆ idle_task_stack_size
| uint32_t rtems_configuration_table::idle_task_stack_size |
This field specifies the size of the IDLE task's stack.
If less than or equal to the minimum stack size, then the IDLE task will have the minimum stack size.
◆ interrupt_stack_size
| uint32_t rtems_configuration_table::interrupt_stack_size |
This field specifies the size of the interrupt stack.
If less than or equal to the minimum stack size, then the interrupt stack will be of minimum stack size.
◆ maximum_key_value_pairs
| uint32_t rtems_configuration_table::maximum_key_value_pairs |
This field contains the maximum number of POSIX API key value pairs which are configured for this application.
- Note
- There can be potentially be a key/value pair for every thread to use every key. But normally this many are not needed in a system.
◆ microseconds_per_tick
| uint32_t rtems_configuration_table::microseconds_per_tick |
This field specifies the number of microseconds which elapse between clock ticks.
This is the basis for RTEMS timing.
◆ nanoseconds_per_tick
| uint32_t rtems_configuration_table::nanoseconds_per_tick |
This field specifies the number of nanoseconds which elapse between clock ticks.
This value is derived from the microseconds_per_tick field and provided to avoid calculation at run-time.
◆ stack_allocator_avoids_work_space
| bool rtems_configuration_table::stack_allocator_avoids_work_space |
Specifies if the stack allocator avoids the work space.
If this element is true, then the stack allocator must not allocate the thread stacks from the RTEMS Workspace, otherwise it should allocate the thread stacks from the RTEMS Workspace.
◆ unified_work_area
| bool rtems_configuration_table::unified_work_area |
Specifies if a unified work area is used or not.
If this element is true, then the RTEMS Workspace and the C Program Heap use the same heap, otherwise they use separate heaps.
