* Remove make preinstallChris Johns2018-01-251-207/+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.
* score: Move thread queue timeout handlingSebastian Huber2017-10-241-1/+0
| | | | | Update #3117. Update #3182.
* score: Rename function threadq support functionSebastian Huber2017-10-241-1/+1
| | | | | | | | | Rename _Thread_queue_Context_set_do_nothing_enqueue_callout() into _Thread_queue_Context_set_enqueue_do_nothing_extra(). More _Thread_queue_Context_set_enqueue_*() functions will follow. Update #3117. Update #3182.
* score: Add _Thread_queue_Object_nameSebastian Huber2017-01-311-1/+1
| | | | | | | | | | | | | Add the special thread queue name _Thread_queue_Object_name to mark thread queues embedded in an object with identifier. Using the special thread state STATES_THREAD_QUEUE_WITH_IDENTIFIER is not reliable for this purpose since the thread wait information and thread state are protected by different SMP locks in separate critical sections. Remove STATES_THREAD_QUEUE_WITH_IDENTIFIER. Add and use _Thread_queue_Object_initialize(). Update #2858.
* score: Add STATES_THREAD_QUEUE_WITH_IDENTIFIERSebastian Huber2017-01-111-1/+1
| | | | | Add thread state bit to identify thread queues that are embedded in an object with identifier.
* score: Optimize _Thread_queue_Enqueue()Sebastian Huber2016-11-241-1/+4
| | | | | | | | | Move thread state for _Thread_queue_Enqueue() to the thread queue context. This reduces the parameter count of _Thread_queue_Enqueue() from five to four (ARM for example has only four function parameter registers). Since the thread state is used after several function calls inside _Thread_queue_Enqueue() this parameter was saved on the stack previously.
* score: Rename _Thread_queue_Enqueue_critical()Sebastian Huber2016-11-231-1/+1
| | | | | Delete unused _Thread_queue_Enqueue() and rename _Thread_queue_Enqueue_critical() to _Thread_queue_Enqueue().
* score: Add thread queue enqueue calloutSebastian Huber2016-11-231-1/+1
| | | | | | | Replace the expected thread dispatch disable level with a thread queue enqueue callout. This enables the use of _Thread_Dispatch_direct() in the thread queue enqueue procedure. This avoids impossible exection paths, e.g. Per_CPU_Control::dispatch_necessary is always true.

* cpukit: Add and use Watchdog_Discipline.Gedare Bloom2016-07-251-3/+0
| | | | | | | | | Clock disciplines may be WATCHDOG_RELATIVE, WATCHDOG_ABSOLUTE, or WATCHDOG_NO_TIMEOUT. A discipline of WATCHDOG_RELATIVE with a timeout of WATCHDOG_NO_TIMEOUT is equivalent to a discipline of WATCHDOG_NO_TIMEOUT. updates #2732
* rtems: Simplify rtems_semaphore_delete()Sebastian Huber2016-05-301-14/+0
| | | | | Due to the unified status codes, we can now use a common flush and destroy method for semaphore and mutex variants.

* score: _CORE_mutex_Check_dispatch_for_seize()Sebastian Huber2016-05-301-1/+2
| | | | | | | | | | | Move the safety check performed by _CORE_mutex_Check_dispatch_for_seize() out of the performance critical path and generalize it. Blocking on a thread queue with an unexpected thread dispatch disabled level is illegal in all system states. Add the expected thread dispatch disable level (which may be 1 or 2 depending on the operation) to Thread_queue_Context and use it in _Thread_queue_Enqueue_critical().
* score: Add Status_Control for all APIsSebastian Huber2016-05-261-57/+12
| | | | | | | | | | | 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.
* Fix semaphore post overflow statusSebastian Huber2016-05-261-1/+2
| | | | Close #2720.
* score: Move thread queue MP callout to contextSebastian Huber2016-05-251-97/+69
| | | | | | | | 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.
* score: Get rid of mp_id parameterSebastian Huber2016-05-251-11/+0
| | | | | Get rid of the mp_id parameter used for some thread queue methods. Use THREAD_QUEUE_QUEUE_TO_OBJECT() instead.
* score: _CORE_semaphore_Seize()Sebastian Huber2016-05-201-2/+0
| | | | Delete unused parameter.
* score: Avoid Giant lock for CORE mtx/semSebastian Huber2016-04-221-19/+27
| | | | | | | Avoid Giant lock for CORE mutex and semaphore flush and delete operations. Update #2555.
* score: Introduce _Thread_queue_Flush_critical()Sebastian Huber2016-04-211-10/+36
| | | | | | | | Replace _Thread_queue_Flush() with _Thread_queue_Flush_critical() and add a filter function for customization of the thread queue flush operation. Update #2555.
* score: Fix _CORE_semaphore_Flush()Sebastian Huber2016-04-211-8/+16
| | | | | | | Use proper CORE_semaphore_Status for _CORE_semaphore_Flush() and _CORE_semaphore_Destroy() operations. Close #2696.
* score: Rework MP thread queue callout supportSebastian Huber2016-04-061-42/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The thread queue implementation was heavily reworked to support SMP. This broke the multiprocessing support of the thread queues. This is fixed by this patch. A thread proxy is unblocked due to three reasons 1) timeout, 2) request satisfaction, and 3) extraction. In case 1) no MPCI message must be sent. This is ensured via the _Thread_queue_MP_callout_do_nothing() callout set during _Thread_MP_Allocate_proxy(). In case 2) and 3) an MPCI message must be sent. In case we interrupt the blocking operation during _Thread_queue_Enqueue_critical(), then this message must be sent by the blocking thread. For this the new fields Thread_Proxy_control::thread_queue_callout and Thread_Proxy_control::thread_queue_id are used. Delete the individual API MP callout types and use Thread_queue_MP_callout throughout. This type is only defined in multiprocessing configurations. Prefix the multiprocessing parameters with mp_ to ease code review. Multiprocessing specific parameters are optional due to use of a similar macro pattern. There is no overhead for non-multiprocessing configurations.
* score: _Thread_queue_Flush() parameter changesSebastian Huber2016-04-061-28/+14
| | | | | | | | | | | | Change _Thread_queue_Flush() into a macro that invokes _Thread_queue_Do_flush() with the parameter set defined by RTEMS_MULTIPROCESSING. For multiprocessing configurations add the object identifier to avoid direct use of the thread wait information. Use mp_ prefix for multiprocessing related parameters. Rename Thread_queue_Flush_callout to Thread_queue_MP_callout since this type will be re-used later for other operations as well.
* score: Delete Thread_Wait_information::idSebastian Huber2016-04-061-1/+0
| | | | | | | | | | | This field was only by the monitor in non-multiprocessing configurations. Add new field Thread_Wait_information::remote_id in multiprocessing configurations and use it for the remote procedure call thread queue. Add _Thread_Wait_get_id() to obtain the object identifier for debug and system information tools. Ensure the object layout via static asserts. Add test cases to sptests/spthreadq01.

* score: Remove Thread_queue_Queue::operations fieldSebastian Huber2016-03-291-22/+13
| | | | | | | | | 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.
* score: Introduce Thread_queue_QueueSebastian Huber2015-07-231-2/+4
| | | | | | Separate the thread queue heads and lock from the operations. This enables the support for light weight objects which only support one queuing discipline.

* score: Add Thread_queue_Control::LockSebastian Huber2015-05-191-7/+12
| | | | | | | | | | | 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.
