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.
2017-09-27score: Rename to _Scheduler_ControlSebastian Huber1-2/+2
Rename struct Scheduler_Control to _Scheduler_Control to allow its use in standard header files, e.g. <pthread.h>. Update #3112.
2016-09-21score: Rework thread priority managementSebastian Huber1-2/+2
Add priority nodes which contribute to the overall thread priority. The actual priority of a thread is now an aggregation of priority nodes. The thread priority aggregation for the home scheduler instance of a thread consists of at least one priority node, which is normally the real priority of the thread. The locking protocols (e.g. priority ceiling and priority inheritance), rate-monotonic period objects and the POSIX sporadic server add, change and remove priority nodes. A thread changes its priority now immediately, e.g. priority changes are not deferred until the thread releases its last resource. Replace the _Thread_Change_priority() function with * _Thread_Priority_perform_actions(), * _Thread_Priority_add(), * _Thread_Priority_remove(), * _Thread_Priority_change(), and * _Thread_Priority_update(). Update #2412. Update #2556.
2016-06-22score: Introduce map priority scheduler operationSebastian Huber1-0/+9
Introduce map/unmap priority scheduler operations to map thread priority values from/to the user domain to/from the scheduler domain. Use the map priority operation to validate the thread priority. The EDF schedulers use this new operation to distinguish between normal priorities and priorities obtain through a job release. Update #2173. Update #2556.
2016-05-30score: Use owner of thread queue for CORE mutexSebastian Huber1-10/+6
2016-05-30score: Rework CORE inherit priority mutexSebastian Huber1-49/+0
Provide dedicated seize and surrender methods for inherit priority mutexes. This eliminates CORE_mutex_Attributes.
2016-05-30score: Rework CORE priority ceiling mutexSebastian Huber1-24/+0
Rework seize and surrender methods to use CORE_ceiling_mutex_Control. This eliminates CORE_mutex_Disciplines.
2016-05-30score: Add CORE mutex variantsSebastian Huber1-13/+30
Add CORE_recursive_mutex_Control and CORE_ceiling_mutex_Control to avoid the run-time evaluation of attributes to figure out how a particular mutex methods should behave. Start with the no protocol variants. This eliminates the CORE_MUTEX_DISCIPLINES_FIFO and CORE_MUTEX_DISCIPLINES_PRIORITY disciplines.
2016-05-30score: Simplify CORE mutexSebastian Huber1-7/+0
Remove superfluous support for simple binary semaphores. With this we can get rid of the CORE_MUTEX_NESTING_BLOCKS variant.
2016-05-02score: Delete __RTEMS_STRICT_ORDER_MUTEX__Sebastian Huber1-25/+0
Remove support for strict order mutexes. Close #2124.
2016-03-29score: Remove Thread_queue_Queue::operations fieldSebastian Huber1-0/+6
Remove the Thread_queue_Queue::operations field to reduce the size of this structure. Add a thread queue operations parameter to the _Thread_queue_First(), _Thread_queue_First_locked(), _Thread_queue_Enqueue(), _Thread_queue_Dequeue() and _Thread_queue_Flush() functions. This is a preparation patch to reduce the size of several synchronization objects.
2014-03-31score: Delete CORE_mutex_Control::lockSebastian Huber1-3/+0
The holder field is enough to determine if a mutex is locked or not. This leads also to better error status codes in case a rtems_semaphore_release() is done for a mutex without having the ownership.

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
