/** * @file * * @brief Configuration Table Template that will be Instantiated * by an Application * * This include file contains the configuration table template that will * be instantiated by an application based on the setting of a number * of macros. The macros are documented in the Configuring a System * chapter of the Classic API User's Guide * * The model is to estimate the memory required for each configured item * and sum those estimates. The estimate can be too high or too low for * a variety of reasons: * * Reasons estimate is too high: * + FP contexts (not all tasks are FP) * * Reasons estimate is too low: * + stacks greater than minimum size * + messages * + application must account for device driver resources * + application must account for add-on library resource requirements * * NOTE: Eventually this may be able to take into account some of * the above. This procedure has evolved from just enough to * support the RTEMS Test Suites into something that can be * used remarkably reliably by most applications. */ /* * COPYRIGHT (c) 1989-2014. * On-Line Applications Research Corporation (OAR). * * The license and distribution terms for this file may be * found in the file LICENSE in this distribution or at * http://www.rtems.org/license/LICENSE. */ #ifndef __CONFIGURATION_TEMPLATE_h #define __CONFIGURATION_TEMPLATE_h /* * Include the executive's configuration */ #include #include #include #ifdef CONFIGURE_DISABLE_BSP_SETTINGS #undef BSP_DEFAULT_UNIFIED_WORK_AREAS #undef BSP_IDLE_TASK_BODY #undef BSP_IDLE_TASK_STACK_SIZE #undef BSP_INITIAL_EXTENSION #undef BSP_INTERRUPT_STACK_SIZE #undef BSP_MAXIMUM_DEVICES #undef BSP_ZERO_WORKSPACE_AUTOMATICALLY #undef CONFIGURE_BSP_PREREQUISITE_DRIVERS #undef CONFIGURE_MALLOC_BSP_SUPPORTS_SBRK #else #include #endif #ifdef RTEMS_NEWLIB #include #endif #ifdef __cplusplus extern "C" { #endif extern rtems_initialization_tasks_table Initialization_tasks[]; #if defined(RTEMS_MULTIPROCESSING) extern rtems_multiprocessing_table Multiprocessing_configuration; #endif #ifdef RTEMS_POSIX_API extern posix_api_configuration_table Configuration_POSIX_API; #endif /** * This macro determines whether the RTEMS reentrancy support for * the Newlib C Library is enabled. */ #ifdef RTEMS_SCHEDSIM #undef RTEMS_NEWLIB #endif #if (defined(RTEMS_NEWLIB) && !defined(CONFIGURE_DISABLE_NEWLIB_REENTRANCY)) #define CONFIGURE_NEWLIB_EXTENSION 1 #else #define CONFIGURE_NEWLIB_EXTENSION 0 #endif #ifndef RTEMS_SCHEDSIM #include #ifdef CONFIGURE_INIT const rtems_libio_helper rtems_libio_init_helper = #ifdef CONFIGURE_APPLICATION_DISABLE_FILESYSTEM rtems_libio_helper_null; #else rtems_libio_init; #endif const rtems_libio_helper rtems_libio_post_driver_helper = #ifdef CONFIGURE_APPLICATION_DISABLE_FILESYSTEM rtems_libio_helper_null; #else rtems_libio_post_driver; #endif const rtems_libio_helper rtems_libio_exit_helper = #ifdef CONFIGURE_APPLICATION_DISABLE_FILESYSTEM rtems_libio_helper_null; #else rtems_libio_exit; #endif const rtems_libio_helper rtems_fs_init_helper = #ifdef CONFIGURE_APPLICATION_DISABLE_FILESYSTEM rtems_libio_helper_null; #else rtems_filesystem_initialize; #endif #endif #endif /* * If the application disables the filesystem, they will not need * a mount table, so do not produce one. */ #ifdef CONFIGURE_APPLICATION_DISABLE_FILESYSTEM #define CONFIGURE_HAS_OWN_MOUNT_TABLE #endif /** * This macro defines the number of POSIX file descriptors allocated * and managed by libio.
