2022-09-19Do not use RTEMS_INLINE_ROUTINESebastian Huber1-9/+9
Directly use "static inline" which is available in C99 and later. This brings the RTEMS implementation closer to standard C. Close #3935.
2022-02-28cpukit/include/rtems/posix/*.h: Change license to BSD-2Joel Sherrill1-3/+22
Updates #3053.
2018-12-14score: Static Objects_Information initializationSebastian Huber1-6/+0
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.
2018-10-29Remove RTEMS_SCORE_OBJECT_ENABLE_STRING_NAMESSebastian Huber1-2/+4
Enable support for string objects names unconditionally. Add const qualifier throughout. Split _Objects_Namespace_remove() into _Objects_Namespace_remove_u32() and _Objects_Namespace_remove_string() to avoid an unnecessary dependency on _Workspace_Free(). Update #2514.
2018-01-25Remove make preinstallChris Johns1-0/+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.
2017-10-05posix: Implement self-contained POSIX semaphoresSebastian Huber1-38/+44
For semaphore object pointer and object validation see POSIX_SEMAPHORE_VALIDATE_OBJECT(). Destruction or close of a busy semaphore returns an error status. The object is not flushed. POSIX semaphores are now available in all configurations and no longer depend on --enable-posix. Update #2514. Update #3116.
2017-09-12posix: Ignore pshared for semaphoresSebastian Huber1-1/+0
Since we have only one process, sharing between processes is trivial. Close #3124.
2016-09-08score: Introduce Thread_queue_Lock_contextSebastian Huber1-1/+1
Introduce Thread_queue_Lock_context to contain the context necessary for thread queue lock and thread wait lock acquire/release operations to reduce the Thread_Control size.
2016-05-30score: Add semaphore variantsSebastian Huber1-0/+2
2016-05-30score: Add _Thread_queue_Context_set_MP_callout()Sebastian Huber1-1/+1
Add _Thread_queue_Context_set_MP_callout() to simplify _Thread_queue_Context_initialize(). This makes it possible to more easily add additional fields to Thread_queue_Context.
2016-05-26score: Add Status_Control for all APIsSebastian Huber1-27/+0
Unify the status codes of the Classic and POSIX API to use the new enum Status_Control. This eliminates the Thread_Control::Wait::timeout_code field and the timeout parameter of _Thread_queue_Enqueue_critical() and _MPCI_Send_request_packet(). It gets rid of the status code translation tables and instead uses simple bit operations to get the status for a particular API. This enables translation of status code constants at compile time. Add _Thread_Wait_get_status() to avoid direct access of thread internal data structures.
2016-05-25score: Move thread queue MP callout to contextSebastian Huber1-4/+5
Drop the multiprocessing (MP) dependent callout parameter from the thread queue extract, dequeue, flush and unblock methods. Merge this parameter with the lock context into new structure Thread_queue_Context. This helps to gets rid of the conditionally compiled method call helpers.
2016-05-20score: Rename _Objects_Get_local()Sebastian Huber1-1/+1
Rename _Objects_Get_local() into _Objects_Get(). Confusions with the previous _Objects_Get() function are avoided since the Objects_Locations parameter is gone.
2016-05-02score: Optimize _Objects_Get_local()Sebastian Huber1-2/+2
Make the interrupt lock context the second parameter to avoid register moves.
2016-04-22posix: Use _Objects_Get_local() for semaphoresSebastian Huber1-7/+4
This simplifies the code since the object location is no longer used. Remove superfluous header includes.
2016-04-22score: Avoid Giant lock for CORE mtx/semSebastian Huber1-23/+3
Avoid Giant lock for CORE mutex and semaphore flush and delete operations. Update #2555.
2016-04-21score: Fix _CORE_semaphore_Flush()Sebastian Huber1-1/+0
Use proper CORE_semaphore_Status for _CORE_semaphore_Flush() and _CORE_semaphore_Destroy() operations. Close #2696.
2016-03-18score: Add _Objects_Get_by_name()Sebastian Huber1-9/+11
Replace _Objects_Name_to_id_string() with _Objects_Get_by_name() since all users of this function are interested in the object itself and not the identifier. Use the object allocator lock to protect the search. Update #2555.
2016-02-03Optional POSIX Semaphore initializationSebastian Huber1-8/+1
Update #2408.
2015-05-19score: Fine grained locking for semaphoresSebastian Huber1-0/+14
Update #2273.
2015-05-19score: Add Thread_queue_Control::LockSebastian Huber1-0/+1
Move the complete thread queue enqueue procedure into _Thread_queue_Enqueue_critical(). It is possible to use the thread queue lock to protect state of the object embedding the thread queue. This enables per object fine grained locking in the future. Delete _Thread_queue_Enter_critical_section(). Update #2273.
2014-03-31score: PR2152: Use allocator mutex for objectsSebastian Huber1-10/+3
Use allocator mutex for objects allocate/free. This prevents that the thread dispatch latency depends on the workspace/heap fragmentation.

This required ensuring that all POSIX and compilering binding code makes a distinction between the public Id type (e.g. pthread_t, etc.) and the RTEMS Object_Id type. All POSIX Object Get routines should not take the POSIX Id type as the argument. Sixteen bit RTEMS Ids should be placed into the 32-bits reserved by the POSIX API type in a uniform manner now. This removed all assumptions that the external Id types in POSIX and ITRON are the same as the internal Object Id type.

Some of these services incorrectly took a timeout as a relative time. Others would compute a 0 delta to timeout if the absolute time and the current time were equal and thus incorrectly block the caller forever. The root of the confusion is that POSIX specifies that if the timeout is incorrect (e.g. in the past, is now, or is numerically invalid), that it does not matter if the call would succeed without blocking. This is in contrast to RTEMS programming style where all errors are checked before any critical sections are entered. This fix implemented a more uniform way of handling POSIX absolute time timeouts. + pthread_cond_timedwait - could block forever + mq_timedreceive - used relative not absolute time + mq_timedsend - used relative not absolute time + pthread_mutex_timedlock - used relative not absolute time + pthread_rwlock_timedrdlock- used relative not absolute time + pthread_rwlock_timedwrlock- used relative not absolute time + sem_timedwait - could block forever
