Detailed Description

Table of User Defined Configuration Parameters.

This include file contains the table of user defined configuration parameters.

Macro Definition Documentation

rtems_configuration_get_do_zero_of_workspace

#define rtems_configuration_get_do_zero_of_workspace

(

)

_Memory_Zero_before_use

This macro assists in accessing the field which indicates whether RTEMS is responsible for zeroing the Executive Workspace.

rtems_configuration_get_maximum_processors

#define rtems_configuration_get_maximum_processors

(

)

(_SMP_Processor_configured_maximum)

Returns the configured maximum count of processors.

The actual number of processors available for the application will be less than or equal to the configured maximum count of processors.

On single-processor configurations this is a compile time constant which evaluates to one.

Returns

The configured maximum count of processors.

rtems_configuration_get_stack_allocator_avoids_work_space

#define rtems_configuration_get_stack_allocator_avoids_work_space

(

)

(_Stack_Allocator_avoids_workspace)

Return if the stack allocator avoids the work space.

Return values

true	The stack allocator must not allocate the thread stacks from the RTEMS Workspace
false	The stack allocator should allocate the thread stacks from the RTEMS Workspace.

rtems_configuration_get_work_space_size

#define rtems_configuration_get_work_space_size

(

)

Value:

(_Workspace_Size + \
          (rtems_configuration_get_stack_allocator_avoids_work_space() ? \
            0 : rtems_configuration_get_stack_space_size()))

Typedef Documentation

rtems_stack_allocate_hook

typedef Stack_Allocator_allocate rtems_stack_allocate_hook

Stack allocator allocate handler.

Parameters

stack_size

The size of the stack area to allocate in bytes.

Return values

NULL	Not enough memory.
other	Pointer to begin of stack area.

rtems_stack_allocate_init_hook

typedef Stack_Allocator_initialize rtems_stack_allocate_init_hook

The stack allocator initialization handler.

Parameters

stack_space_size

The size of the stack space in bytes.

rtems_stack_free_hook

typedef Stack_Allocator_free rtems_stack_free_hook

Stack allocator free handler.

Parameters

]	addr A pointer to previously allocated stack area or NULL.
