* rtems: Add rtems_get_build_label()Sebastian Huber2021-02-251-0/+50
| | | | Update #4269.
* config: Adjust stack allocator initializationSebastian Huber2021-02-241-1/+10
| | | | | | | Use the right system initialization step for the stack allocator initialization. Do the stack allocator initialization before the workspace initialization so that _Memory_Allocate() can be used to get memory for the allocator.
* score: Remove _Objects_Open()Sebastian Huber2021-02-241-4/+2
| | | | | Use the type safe _Objects_Open_u32() instead. Return the object identifier to enforce a common usage pattern.
* Update copyright notice to 2021Sebastian Huber2021-01-271-1/+1
|
* cpucounter: Increase conversion accuracySebastian Huber2021-01-261-3/+4
| | | | | | The maximum frequency is UINT32_MAX. Converted to a uint64_t variable it can be shifted by 32. The addition does not overflow since bin_per_s - 1 is UINT32_MAX.
* sapi: Canonicalize @defgroup and @file commentsSebastian Huber2020-12-0239-69/+208
| | | | | | | 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.
* rtems: Canonicalize implementation Doxygen groupsSebastian Huber2020-12-021-1/+1
| | | | | | | | | Rename Classic API top-level group from Classic to RTEMSImplClassic. Use RTEMSImplClassic as a prefix for the subgroups. Change the group names to be in line with the API group names. Use common phrases for the group brief descriptions. Update #3706.
* rtems: Simplify includes in version.cSebastian Huber2020-12-021-1/+1
|
* posix: Delete unused _POSIX_Fatal_error()Sebastian Huber2020-12-021-179/+0
|
* 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.
* rtems: Move from <rtems.h> to <rtems/config.h>Sebastian Huber2020-09-182-2/+2
| | | | | | Move configuration related declarations and definitions to <rtems/config.h>. The goal is to make <rtems.h> an include only header file.
* 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.
* rtems: Add _RTEMS_Name_to_id()Sebastian Huber2020-08-311-21/+31
| | | | | | | | | | Simplify object name to identifier directives. Using _RTEMS_Name_to_id() to implement the directives enables a tail call optimization. Change license to BSD-2-Clause according to file history. Update #3053.
* rtems: Move declartion of _RTEMS_versionSebastian Huber2020-07-141-2/+1
| | | | Close #3978.
* score: Update _Copyright_NoticeSebastian Huber2020-05-061-3/+2
| | | | | Add the _Copyright_Notice to a special linker set to prevent a garbage collection of this item.
* rtems: Deprecate _Copyright_NoticeSebastian Huber2020-05-061-0/+2
| | | | Close #3973.
* rtems: Add rtems_get_copyright_notice()Sebastian Huber2020-05-061-0/+46
| | | | Update #3973.
* rtems: Deprecate use of _RTEMS_versionSebastian Huber2020-05-061-0/+2
| | | | Close #3970.
* doxygen: Switch @brief and @ingroupSebastian Huber2020-04-281-1/+2
| | | | This order change fixes the Latex documentation build via Doxygen.
* sapi: Add param check to rtems_extension_create()Sebastian Huber2020-04-171-4/+10
| | | | | | Check that the extensions table is not NULL. Change format. Update #3953.
* Canonicalize config.h includeSebastian Huber2020-04-1636-41/+41
| | | | | | | | Use the following variant which was already used by most source files: #ifdef HAVE_CONFIG_H #include "config.h" #endif
* config: Initialize IO drivers on demandSebastian Huber2020-02-262-13/+45
|
* libio: Add POSIX user environment pointer to TCBSebastian Huber2020-02-251-1/+9
| | | | | | | | | | 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.
* sysinit: Add RTEMS_SYSINIT_ZERO_MEMORYSebastian Huber2020-02-061-1/+9
| | | | | | | | Use a dedicate system initialization step to zero the memory used for the workspace and C program heap. This avoids dead code in case CONFIGURE_ZERO_WORKSPACE_AUTOMATICALLY is not configured.
* config: Add CONFIGURE_VERBOSE_SYSTEM_INITIALIZATIONSebastian Huber2020-02-041-0/+557
| | | | Update #3861.
* Use RTEMS_SYSINIT_ORDER_LAST_BUT_5Sebastian Huber2020-02-041-1/+1
| | | | | | | | Use RTEMS_SYSINIT_ORDER_LAST_BUT_5 instead of RTEMS_SYSINIT_ORDER_LAST to allow applications and support functions to place system initialization handlers behind the standard handlers. Update #3838.
* bsps: Rework work area initializationSebastian Huber2020-02-041-0/+13
| | | | | | | | | | | | | | | | | | | | The work area initialization was done by the BSP through bsp_work_area_initialize(). This approach predated the system initialization through the system initialization linker set. The workspace and C program heap were unconditionally initialized. The aim is to support RTEMS application configurations which do not need the workspace and C program heap. In these configurations, the workspace and C prgram heap should not get initialized. Change all bsp_work_area_initialize() to implement _Memory_Get() instead. Move the dirty memory, sbrk(), per-CPU data, workspace, and malloc() heap initialization into separate system initialization steps. This makes it also easier to test the individual initialization steps. This change adds a dependency to _Heap_Extend() to all BSPs. This dependency will be removed in a follow up change. Update #3838.
* rtems-5: Improve heap fatal error informationsebastian.huber2019-11-051-2/+3
| | | | Update #3806.
* rtems: Make rtems_version_control_key() saferSebastian Huber2019-09-091-1/+1
| | | | | Return the empty string instead of a NULL pointer if no version key is available.
* rtems: Add rtems_scheduler_get_processor_maximum()Sebastian Huber2019-04-091-1/+1
| | | | | | | | | | | Add rtems_scheduler_get_processor_maximum() as a replacement for rtems_get_processor_count(). The rtems_get_processor_count() is a bit orphaned. Adopt it by the Scheduler Manager. The count is also misleading, since the processor set may have gaps and the actual count of online processors may be less than the value returned by rtems_get_processor_count(). Update #3732.
* doxygen: Rename Score* groups in RTEMSScore*Sebastian Huber2019-04-041-1/+1
| | | | Update #3706
* doxygen: Added Version to API->ClassicAndreas Dachsberger2019-04-041-1/+1

* Remove superfluous <rtems/system.h> includesSebastian Huber2019-03-144-4/+0

* 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.
* score: Static Objects_Information initializationSebastian Huber2018-12-142-33/+43
| | | | | | | | | | | 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.
* rtems: Use object information to get config maxSebastian Huber2018-12-142-1/+103
| | | | | | | Use functions instead of macros. Add missing rtems_configuration_get_maximum_*() functions. Update #3621.
* score: Remove Objects_Information::is_stringSebastian Huber2018-12-071-2/+1
| | | | | | Use Objects_Information::name_length to store this information. Update #3621.
* Convert CPU counter ticks to/from sbintime_tSebastian Huber2018-12-031-2/+20
| | | | | The sbintime_t is an efficient time format. Add the ability to convert CPU counter ticks to/from sbintime_t.
* Rename files to make them unique within cpukitSebastian Huber2018-10-041-0/+0
| | | | This allows to build librtemscpu.a in one rush in the future.
* Add _CPU_Counter_frequency()Sebastian Huber2018-06-151-3/+15
| | | | | | | | | | Add rtems_counter_frequency() API function. Use it to initialize the counter value converter via the new system initialization step (RTEMS_SYSINIT_CPU_COUNTER). This decouples the counter implementation and the counter converter. It avoids an unnecessary pull in of the 64-bit integer division from libgcc. Update #3456.
* Add RTEMS_FATAL_SOURCE_INVALID_HEAP_FREESebastian Huber2018-06-051-1/+2
| | | | | | | | 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.
* Update rtems_fatal_source_text()Sebastian Huber2018-06-051-2/+3
| | | | | | Add RTEMS_FATAL_SOURCE_PANIC to rtems_fatal_source_text(). Update #3244.
* score: Use self-contained API mutexSebastian Huber2017-12-041-9/+0
| | | | | | | | | | Use a self-contained recursive mutex for API_Mutex_Control. The API mutexes are protected against asynchronous thread cancellation. Add dedicated mutexes for libatomic and TOD. Close #2629. Close #2630.
* sapi/src/panic.c: Add include of <rtems/bspIo.h>Joel Sherrill2017-11-291-0/+1

* sapi: New implementation of rtems_panic()Sebastian Huber2017-11-221-0/+32
| | | | | | | | | | | | The previous rtems_panic() implementation was quite heavy weight. It depended on _exit() which calls the global destructors. It used fprintf(stderr, ...) for output which depends on an initialized console device and the complex fprintf(). Introduce a new fatal source RTEMS_FATAL_SOURCE_PANIC for rtems_panic() and output via vprintk(). Update #3244.
* 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.
* cpukit: Add a Version API.Chris Johns2017-11-101-0/+63
| | | | | | | | Provide functions to get the version string, major, minor and revision numbers and the version control identifer that is a unique tag for the version control system. Update #3199.
* posix: Implement self-contained POSIX mutexSebastian Huber2017-10-051-0/+37
| | | | | | | | POSIX mutexes are now available in all configurations and no longer depend on --enable-posix. Update #2514. Update #3112.
* posix: Implement self-contained POSIX condvarSebastian Huber2017-10-051-0/+33
| | | | | | | | POSIX condition variables are now available in all configurations and no longer depend on --enable-posix. Update #2514. Update #3113.
* posix: Implement self-contained POSIX rwlocksSebastian Huber2017-10-051-0/+29
| | | | | | | | POSIX rwlocks are now available in all configurations and no longer depend on --enable-posix. Update #2514. Update #3115.
