* Add pthread_getconcurrency() and pthread_setconcurrency()Joel Sherrill2016-04-142-0/+43
| | | | | | | | | This is the very simple implementation specified by the Open Group for implementations with 1:1 kernel thread to user thread mappings. http://pubs.opengroup.org/onlinepubs/9699919799/functions/pthread_getconcurrency.html updates #2680.
* posix: Run key destructors during thread restartSebastian Huber2016-04-141-0/+10
| | | | | | | | | | POSIX key destructors must be called during thread restart. Just like the POSIX cleanup handlers. This ensures that the TLS object destructors are called during thread restart for example. It is important for the global construction, which uses a thread restart to run the Init task in a clean environment. Close #2689.

| | | | | | rcsid is defined, but not used. So discard it. Signed-off-by: Peng Fan <van.freenix@gmail.com>

* posix: Rename killinfo()Sebastian Huber2016-04-125-5/+5
| | | | | | Apparently killinfo() is not defined by POSIX, glibc or FreeBSD. Rename killinfo() to _POSIX_signals_Send() to cleary mark it as an internal function.

| | | | | Get region and lock allocator in _Region_Get_and_lock() in case the region exists and unlock it in _Region_Unlock().
* score: Simplify _Objects_Get_no_protection()Sebastian Huber2016-04-1214-341/+207
| | | | | | | This functions supports only local objects. Thus, drop the location parameter which was unused by all callers. Remove superfluous includes from Classic Region implementation.

* libblock: Drop superfluous <stdlib.h> includeSebastian Huber2016-04-077-1/+6
| | | | | | Drop superfluous <stdlib.h> include from <rtems/diskdevs.h> since this leads to conflicts with the latest Newlib in case this header file is used in the FreeBSD kernel space, e.g. for USB mass storage support.
* network: Quirk for Newlib compatibilitySebastian Huber2016-04-071-0/+1
| | | | | Newlib provides now a declration for random() in <stdlib.h>. This confilicts with the define in <rtems/rtems_bsdnet_internal.h>.

* score: Rework MP thread queue callout supportSebastian Huber2016-04-0637-458/+795
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Simplify _Thread_queue_Do_flush()Sebastian Huber2016-04-061-4/+1
| | | | | Also set the thread wait return code for thread proxies since this causes no harm.
* score: _Thread_queue_Flush() parameter changesSebastian Huber2016-04-0621-193/+186
| | | | | | | | | | | | 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: Fix _Thread_queue_Extract_locked()Sebastian Huber2016-04-061-4/+8
| | | | | | We must update the wait flags under protection of the current thread lock, otherwise a _Thread_Timeout() running on another processor may interfere.
* score: Delete MP support for RW locksSebastian Huber2016-04-069-54/+19
| | | | MP support was not implemented.
* score: Delete Thread_Wait_information::idSebastian Huber2016-04-0632-41/+188
| | | | | | | | | | | 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: _User_extensions_Remove_set()Sebastian Huber2016-03-311-1/+4
| | | | | | | Use unprotected chain operation in _User_extensions_Remove_set() since the caller must own the object allocator lock. Update #2555.
* Move various driver interface definition headers file libcsupport/ to include/Joel Sherrill2016-03-309-25/+31
| | | | | | | | | | | These were in libcsupport for historical reasons and the placement no longer made sense. As part of this move, some of the files were placed under subdirectories which reflect their installed location. Thank you git for allowing us to move files. Years of CVS resulted in files being somewhere they no longer belonged.
* score: Objects_Thread_queue_Extract_calloutSebastian Huber2016-03-3010-23/+28
| | | | | Change parameters of the objects thread queue extract callout to avoid a cast and explicit use of the thread wait information.
