* Update company nameSebastian Huber2023-05-201-1/+1
| | | | | The embedded brains GmbH & Co. KG is the legal successor of embedded brains GmbH.
* 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 Huber2022-10-141-1/+2
| | | | | | 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.
* cpukit/: Scripted embedded brains header file clean upJoel Sherrill2022-03-101-6/+0
| | | | Updates #4625.
* sapi/src/*.c: Change license to BSD-2Joel Sherrill2022-02-281-3/+22
| | | | Updates #3053.
* sapi: Canonicalize @defgroup and @file commentsSebastian Huber2020-12-021-2/+3
| | | | | | | Adjust group identifier and names to be in line with a common pattern. Use common phrases for the group and file 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.
* CONFIGURE_MAXIMUM_THREAD_LOCAL_STORAGE_SIZESebastian Huber2020-09-171-2/+3
| | | | | | | | | | | 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.
* Canonicalize config.h includeSebastian Huber2020-04-161-2/+2
| | | | | | | | Use the following variant which was already used by most source files: #ifdef HAVE_CONFIG_H #include "config.h" #endif
* score: Fix per-CPU data allocationSebastian Huber2018-12-181-2/+3
| | | | | | | | | | | 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.
* cpukit: Add _arc4random_getentropy_fail.Christian Mauderer2017-11-171-1/+2
| | | | | | | Add a default implementation of _arc4random_getentropy_fail with an internal error. Update #3239.
* INTERNAL_ERROR_ILLEGAL_USE_OF_FLOATING_POINT_UNITSebastian Huber2017-07-251-2/+3
| | | | | | Add new fatal error INTERNAL_ERROR_ILLEGAL_USE_OF_FLOATING_POINT_UNIT. Update #3077.
* Add INTERNAL_ERROR_LIBIO_STDERR_FD_OPEN_FAILEDSebastian Huber2016-12-121-1/+2
| | | | Update #2825.
* Add INTERNAL_ERROR_LIBIO_STDOUT_FD_OPEN_FAILEDSebastian Huber2016-12-121-1/+2
| | | | Update #2825.
* Add INTERNAL_ERROR_LIBIO_SEM_CREATE_FAILEDSebastian Huber2016-12-121-1/+2
| | | | Update #2825.
* INTERNAL_ERROR_LIBIO_USER_ENV_KEY_CREATE_FAILEDSebastian Huber2016-12-121-1/+2
| | | | Update #2825.
* Add INTERNAL_ERROR_POSIX_INIT_THREAD_CREATE_FAILEDSebastian Huber2016-12-121-1/+2
| | | | Update #2825.
* Add INTERNAL_ERROR_RTEMS_INIT_TASK_CREATE_FAILEDSebastian Huber2016-12-121-1/+2
| | | | Update #2825.
* score: Uncomment unused internal error codesSebastian Huber2016-11-231-3/+3
| | | | Update #2825.
* score: Add thread queue enqueue calloutSebastian Huber2016-11-231-1/+1
| | | | | | | Replace the expected thread dispatch disable level with a thread queue enqueue callout. This enables the use of _Thread_Dispatch_direct() in the thread queue enqueue procedure. This avoids impossible exection paths, e.g. Per_CPU_Control::dispatch_necessary is always true.
* score: Robust thread dispatchSebastian Huber2016-11-231-1/+2
| | | | | | | | | | | | On SMP configurations, it is a fatal error to call blocking operating system with interrupts disabled, since this prevents delivery of inter-processor interrupts. This could lead to executing threads which are not allowed to execute resulting in undefined behaviour. The ARM Cortex-M port has a similar problem, since the interrupt state is not a part of the thread context. Update #2811.
* score: Add and use _Thread_Dispatch_direct()Sebastian Huber2016-11-181-1/+2
| | | | | | | | | | This function is useful for operations which synchronously block, e.g. self restart, self deletion, yield, sleep. It helps to detect if these operations are called in the wrong context. Since the thread dispatch necessary indicator is not used, this is more robust in some SMP situations. Update #2751.
* score: First part of new MrsP implementationSebastian Huber2016-11-021-1/+2
| | | | Update #2556.
* score: Add deadlock detectionSebastian Huber2016-07-271-2/+3
| | | | | | | | | | The mutex objects use the owner field of the thread queues for the mutex owner. Use this and add a deadlock detection to _Thread_queue_Enqueue_critical() for thread queues with an owner. Update #2412. Update #2556. Close #2765.
* score: _CORE_mutex_Check_dispatch_for_seize()Sebastian Huber2016-05-301-1/+1
| | | | | | | | | | | Move the safety check performed by _CORE_mutex_Check_dispatch_for_seize() out of the performance critical path and generalize it. Blocking on a thread queue with an unexpected thread dispatch disabled level is illegal in all system states. Add the expected thread dispatch disable level (which may be 1 or 2 depending on the operation) to Thread_queue_Context and use it in _Thread_queue_Enqueue_critical().
* score: Add fatal errors for NULL entry init tasksSebastian Huber2016-01-081-2/+4
| | | | | | This simplifies the global construction. Update #2514.
* score: Simplify debug code and use _Assert()Sebastian Huber2015-03-221-1/+1

* score: PR788: Add INTERNAL_ERROR_RESOURCE_IN_USESebastian Huber2014-04-031-1/+2
| | | | | | | | | | | | | | | Issue a fatal error in case a thread is deleted which still owns resources (e.g. a binary semaphore with priority inheritance or ceiling protocol). The resource count must be checked quite late since RTEMS task variable destructors, POSIX key destructors, POSIX cleanup handler, the Newlib thread termination extension or other thread termination extensions may release resources. In this context it would be quite difficult to return an error status to the caller. An alternative would be to place threads with a non-zero resource count not on the zombie chain. Thus we have a resource leak instead of a fatal error. The terminator thread can see this error if we return an RTEMS_RESOURCE_IN_USE status for the rtems_task_delete() for example.

* score: Delete INTERNAL_ERROR_SHUTDOWN_WHEN_NOT_UPSebastian Huber2014-02-191-1/+1
| | | | | This error case is no longer required since rtems_shutdown_executive() can be called anytime, anywhere

Rename rtems_internal_error_description() to rtems_internal_error_text(). Rename rtems_fatal_source_description() to rtems_fatal_source_text(). Rename rtems_status_code_description() to rtems_status_text(). Remove previous implementation of rtems_status_text().
