* cpukit/rtems/src/[s-z]*.c: Change license to BSD-2Joel Sherrill2022-02-281-3/+22
| | | | Updates #3053.
* score: Introduce CPU budget operationsSebastian Huber2021-11-151-3/+6
| | | | | | | | | | | | | | This patch set replaces the CPU budget algorithm enumeration with a set of CPU budget operations which implement a particular CPU budget algorithm. This helps to hide the CPU budget algorithm implementation details from the general thread handling. The CPU budget callouts are turned into CPU budget operations. This slightly reduces the size of the thread control block. All schedulers used the default scheduler tick implementation. The tick scheduler operation is removed and the CPU budget operations are directly used in _Watchdog_Tick() if the executing thread uses a CPU budget algorithm. This is performance improvement for all threads which do not use a CPU budget algorithm (default behaviour).
* score: Rename _Stack_Free_nothing()Sebastian Huber2021-05-111-1/+1
| | | | | | | Rename _Stack_Free_nothing() in _Objects_Free_nothing() to make it reusable for the message queue buffers. Update #4007.
* rtems: Check for NULL config in task constructSebastian Huber2021-04-231-0/+4
| | | | | | | Since there are already excessive NULL pointer checks in the Classic API, do this also in rtems_task_construct(). Update #3959.
* score: Replace Objects_Name_or_id_lookup_errorsSebastian Huber2021-04-071-0/+4
| | | | | Replace Objects_Name_or_id_lookup_errors with new Status_Control codes. Get rid of the _Status_Object_name_errors_to_status lookup table.
* score: Fix internal error status numberSebastian Huber2021-04-071-0/+22
| | | | | | The value of STATUS_CLASSIC_INTERNAL_ERROR must be equal to RTEMS_INTERNAL_ERROR. Add static assertions to ensure that the status codes match.
* score: Fix thread initializationSebastian Huber2021-02-261-16/+7
| | | | | | | | Close the thread object if a thread create extension fails. Also call the delete extension to avoid resource leaks in early extensions if a late extension fails. Close #4270.
* score: Remove _Objects_Open()Sebastian Huber2021-02-241-1/+1
| | | | | Use the type safe _Objects_Open_u32() instead. Return the object identifier to enforce a common usage pattern.
* score: Add _Thread_Get_objects_information()Sebastian Huber2021-02-011-0/+8
| | | | | | | | | | | | | | | | | | | | | We do not need all the checks if we have a valid indentifier to a thread class object. Using the new _Thread_Get_objects_information() instead of the inline function _Thread_Get_objects_information_by_id() avoids dead code since the identifier in a thread control is always valid and the return NULL path in _Thread_Get_objects_information_by_id() would be dead code. The _Thread_Get_objects_information_by_id() should be an inline function since it is used by _Thread_Get() and thus performance critical. Static analyzers which cannot derive that the identifier in a thread control is always valid, may find a potential NULL pointer access (or otherwise find dead code). The identifier in an object control is always valid, see _Objects_Initialize_information() and _Objects_Extend_information(). Move _RTEMS_tasks_Free() to the only source file which calls this function.
* rtems: Canonicalize Doxygen @file commentsSebastian Huber2020-12-021-2/+3
| | | | | | Use common phrases for the file brief descriptions. Update #3706.
* Remove *_Is_null() inline functionsSebastian Huber2020-10-141-1/+1
| | | | Simply compare the values against NULL.
* rtems: Canonicalize name and id checksSebastian Huber2020-10-011-4/+6
| | | | | | Check the name followed by the id check in all create directives. Compare pointers against NULL. Fix formatting.
* rtems: Add rtems_task_construct()Sebastian Huber2020-09-171-0/+300
In contrast to rtems_task_create() this function constructs a task with a user-provided task storage area. The new directive uses a configuration structure instead of individual parameters. Add RTEMS_TASK_STORAGE_SIZE() to calculate the recommended size of a task storage area based on the task attributes and the size dedicated to the task stack and thread-local storage. This macro may allow future extensions without breaking the API. Add application configuration option CONFIGURE_MINIMUM_TASKS_WITH_USER_PROVIDED_STORAGE to adjust RTEMS Workspace size estimate. Update #3959.
