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

(

)

(Configuration.do_zero_of_workspace)

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

(

)

1

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_work_space_size

#define rtems_configuration_get_work_space_size

(

)

Value:

(Configuration.work_space_size + \
          (rtems_configuration_get_stack_allocator_avoids_work_space() ? \
            0 : rtems_configuration_get_stack_space_size()))

rtems_configuration_is_smp_enabled

#define rtems_configuration_is_smp_enabled

(

)

false

Returns true if the SMP mode of operation is enabled, and false otherwise.

In uni-processor configurations this is a compile-time constant which evaluates to false.

Return values

true	SMP mode of operation is enabled.
false	Otherwise.

Typedef Documentation

rtems_stack_allocate_hook

typedef void*(* rtems_stack_allocate_hook) (size_t stack_size)

Task stack allocator hook.

Parameters

[in]

stack_size

is the Size of the task stack in bytes.

Return values

NULL	Not enough memory.
other	Pointer to task stack.

rtems_stack_allocate_init_hook

typedef void(* rtems_stack_allocate_init_hook) (size_t stack_space_size)

Task stack allocator initialization hook.

Parameters

[in]

stack_space_size

is the size of the stack space in bytes.

rtems_stack_free_hook

typedef void(* rtems_stack_free_hook) (void *addr)

Task stack deallocator hook.

Parameters

[in]

addr

is a pointer to previously allocated task stack.
