* score: INTERNAL_ERROR_IDLE_THREAD_STACK_TOO_SMALLSebastian Huber2022-10-141-1/+2
| | | | | | | Ensure that the IDLE storage allocator did allocate a suffiently large area. Update #3835. Update #4524.
* config: Add CONFIGURE_IDLE_TASK_STORAGE_SIZESebastian Huber2022-10-141-1/+2
| | | | | | | | | | | | By default, allocate the IDLE task storage areas from the RTEMS Workspace. This avoids having to estimate the thread-local storage size in the default configuration. Add the application configuration option CONFIGURE_IDLE_TASK_STORAGE_SIZE to request a static allocation of the task storage area for IDLE tasks. Update #3835. Update #4524.
* score: INTERNAL_ERROR_IDLE_THREAD_CREATE_FAILEDSebastian Huber2022-10-141-0/+1
| | | | | | Add the INTERNAL_ERROR_IDLE_THREAD_CREATE_FAILED fatal error in case the creation of an idle thread fails. This may happen due to a failing create extension provided by the application.
* score: Do not expose <limits.h> to <rtems.h>Sebastian Huber2022-08-301-3/+1
| | | | | | | | The <rtems.h> header file should not unnecessarily include standard C header files. The <string.h> and <limits.h> header includes were removed in 2017. Update #4662.
* interr.h: Fix gcc 12 warningRyan Long2022-08-191-1/+3
| | | | | | | The warning that this fixes states that "ISO C restricts enumerator values to range of 'int'." Updates #4662
* cpukit/include/rtems/score/[a-r]*.h: Change license to BSD-2Joel Sherrill2022-02-281-3/+22
| | | | Updates #3053.
* Remove obsolete rtems_gxx_*() implementationSebastian Huber2022-01-271-2/+2
| | | | | | | | | | | GCC versions prior to 6.1 used a RTEMS thread model based on rtems_gxx_*() functions. GCC version 6.1 or later uses the self-contained synchronization objects of Newlib <sys/lock.h> for the RTEMS thread model. Remove the obsolete implementation. Close #3143.
* score: Remove _Internal_errors_What_happenedSebastian Huber2021-07-281-17/+1
| | | | | | | | | | Users have access to the fatal error source and code though the fatal error extension. The user-specific fatal error handling should be done in statically initialized fatal error handlers. The _Internal_errors_What_happened was updated after the fatal error extension. In addition, there was no API to get the information stored in _Internal_errors_What_happened. In SMP configurations, this object could contain a mix of different fatal errors. Remove this object to save some bytes of storage.
* rtems: Add RTEMS_FATAL_SOURCE_SPURIOUS_INTERRUPTSebastian Huber2021-07-261-0/+7
| | | | | | | | Add RTEMS_FATAL_SOURCE_SPURIOUS_INTERRUPT as the fatal source for spurious interrupts. Use the interrupt vector number of the spurious interrupt for the fatal code. Update #3269.
* score: Canonicalize Doxygen @file commentsSebastian Huber2020-12-021-4/+2
| | | | | | Use common phrases for the file brief descriptions. Update #3706.
* score: Canonicalize Doxygen groupsSebastian Huber2020-12-021-3/+2
| | | | | | | Adjust group identifier and names to be in line with a common pattern. Use common phrases for the group brief descriptions. Update #3706.
* config: CONFIGURE_INIT_TASK_CONSTRUCT_STORAGE_SIZESebastian Huber2020-11-261-1/+2
| | | | | | | | | | In order to better support applications which use the new rtems_task_construct() directive add the CONFIGURE_INIT_TASK_CONSTURCT_STORAGE_SIZE configuration option. If this option is specified, then the Classic API initialization task is constructed with rtems_task_construct(). Update #4181.
* Avoid INTERNAL_ERROR_RTEMS_INIT_TASK_ENTRY_IS_NULLSebastian Huber2020-11-261-1/+1
| | | | | | | Replace a runtime check with a compile time assertion. This makes the INTERNAL_ERROR_RTEMS_INIT_TASK_ENTRY_IS_NULL obsolete. Update #4181.
* config: Simplify task stack allocator initSebastian Huber2020-11-191-1/+1
| | | | | Replace runtime checks with compile time assertions. This makes the INTERNAL_ERROR_BAD_STACK_HOOK obsolete.
* rtems: Improve RTEMS_NO_RETURN attributeSebastian Huber2020-10-101-3/+3
| | | | | | | | | | | Provide RTEMS_NO_RETURN also in case RTEMS_DEBUG is defined to prevent errors like this: error: no return statement in function returning non-void [-Werror=return-type] Use C11 and C++11 standard means to declare a no-return function. Close #4122.
* CONFIGURE_MAXIMUM_THREAD_LOCAL_STORAGE_SIZESebastian Huber2020-09-171-1/+2
| | | | | | | | | | | Add this application configuration option. This configuration option can be used to reserve space for the dynamic linking of modules with thread-local storage objects. Add RTEMS_TASK_STORAGE_ALIGNMENT to define the minium alignment of a thread-local storage size. Update #4074.
* libio: Add POSIX user environment pointer to TCBSebastian Huber2020-02-251-1/+1
| | | | | | | | | | The IO library used a POSIX key to store an optional POSIX user environment pointer. This pulled in the POSIX keys support in every application configuration. Add a user environment pointer to the thread control block (TCB) instead. Applications which do not need the POSIX user environment will just get an overhead of one pointer per thread. Close #3882.
* score: Remove _Workspace_Allocate_or_fatal_error()Sebastian Huber2019-12-131-1/+1
| | | | | | This function is unused. Update #3735.

* Remove explicit file names from @fileSebastian Huber2019-02-281-1/+1
| | | | | | This makes the @file documentation independent of the actual file name. Update #3707.
* score: Fix per-CPU data allocationSebastian Huber2018-12-181-1/+2
| | | | | | | | | | | Allocate the per-CPU data for secondary processors directly from the heap areas before heap initialization and not via _Workspace_Allocate_aligned(). This avoids dependency on the workspace allocator. It fixes also a problem on some platforms (e.g. QorIQ) where at this early point in the system initialization the top of the RAM is used by low-level startup code on secondary processors (boot pages). Update #3507.
* score: Static Objects_Information initializationSebastian Huber2018-12-141-1/+1
| | | | | | | | | | | Statically allocate the objects information together with the initial set of objects either via <rtems/confdefs.h>. Provide default object informations with zero objects via librtemscpu.a. This greatly simplifies the workspace size estimate. RTEMS applications which do not use the unlimited objects option are easier to debug since all objects reside now in statically allocated objects of the right types. Close #3621.
* Remove INTERNAL_ERROR_INTERRUPT_STACK_TOO_SMALLSebastian Huber2018-09-211-1/+1
| | | | | | | | | | | | The configured interrupt stack size (CONFIGURE_INTERRUPT_STACK_SIZE) is checked against the minimum task stack size. The minium tasks task stack size is also a configuration option (CONFIGURE_MINIMUM_TASK_STACK_SIZE). So, this check does not really help in case of configuration errors. In addition, the interrupt stack is also re-used as the initialization stack in most BSPs. It is probably better to use a stack checker to detect problems. Update #3459.
* Add RTEMS_FATAL_SOURCE_INVALID_HEAP_FREESebastian Huber2018-06-051-0/+7
| | | | | | | | An invalid heap usage such as a double free is usually a fatal error since this indicates a use after free. Replace the use of printk() in free() with a fatal error. Update #3437.
* Remove make preinstallChris Johns2018-01-251-0/+268
A speciality of the RTEMS build system was the make preinstall step. It copied header files from arbitrary locations into the build tree. The header files were included via the -Bsome/build/tree/path GCC command line option. This has at least seven problems: * The make preinstall step itself needs time and disk space. * Errors in header files show up in the build tree copy. This makes it hard for editors to open the right file to fix the error. * There is no clear relationship between source and build tree header files. This makes an audit of the build process difficult. * The visibility of all header files in the build tree makes it difficult to enforce API barriers. For example it is discouraged to use BSP-specifics in the cpukit. * An introduction of a new build system is difficult. * Include paths specified by the -B option are system headers. This may suppress warnings. * The parallel build had sporadic failures on some hosts. This patch removes the make preinstall step. All installed header files are moved to dedicated include directories in the source tree. Let @RTEMS_CPU@ be the target architecture, e.g. arm, powerpc, sparc, etc. Let @RTEMS_BSP_FAMILIY@ be a BSP family base directory, e.g. erc32, imx, qoriq, etc. The new cpukit include directories are: * cpukit/include * cpukit/score/cpu/@RTEMS_CPU@/include * cpukit/libnetworking The new BSP include directories are: * bsps/include * bsps/@RTEMS_CPU@/include * bsps/@RTEMS_CPU@/@RTEMS_BSP_FAMILIY@/include There are build tree include directories for generated files. The include directory order favours the most general header file, e.g. it is not possible to override general header files via the include path order. The "bootstrap -p" option was removed. The new "bootstrap -H" option should be used to regenerate the "headers.am" files. Update #3254.
