* rtems: Add RTEMS_FATAL_SOURCE_SPURIOUS_INTERRUPTSebastian Huber2021-07-261-1/+2
| | | | | | | | 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: Add PER_CPU_DATA_NEED_INITIALIZATION()Sebastian Huber2021-06-101-13/+0
| | | | | | | | | Make the initialization of the per-CPU data optional. Change license to BSD-2-Clause according to file history and re-licensing agreement. Update #3053.
* Remove superfluous <rtems/score/wkspace.h> includesSebastian Huber2021-04-201-1/+0

* Add system initialization step for target hashSebastian Huber2021-02-261-1/+9
| | | | Update #4267.
* 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

* 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.

| | | | 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

* 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.
* build: Move sapi/Makefile.amSebastian Huber2018-10-093-109/+0
|
* Rename files to make them unique within cpukitSebastian Huber2018-10-042-1/+1
| | | | 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.
* build: Remove EXTRA_DISTSebastian Huber2018-04-041-1/+0
| | | | | A "make dist" is not supported. So, it makes no sense to have pure "make dist" related stuff in the Makefile.am.
* Remove make preinstallChris Johns2018-01-2522-8315/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
